The article examines the principles and directions of the state policy of the USA on the nature protection in the early XX century, which is named conservation. It was determined that its precondition is the growing attention to wildlife of American philosophers, artists, writers, scientists who contributed to the formation of ecological consciousness in society. The article analyses the role of the USA President T. Roosevelt in development of conservation policy and its main areas: creation of public land reserve, including national forests and parks, forest conservation, water resources, reclamation of arid areas, initiating of various commissions that have to audit natural resources of the USA. The role of Governors’ Meeting (1908) and the National Congress on Conservation (1909) in the activization of the movement for conservation of natural resources in the United States is considered. It is proved that President Т. Roosevelt formulated the ideals of the American society on nature conservation, based on the values of civilization, patriotism and social morality, which became the basis of environmental policy in late XX – early XXI century.

Although millions of people recreate in parks, forests, and other conservation areas in the United States every year, research shows that some are left out; not everyone takes advantage of natural areas for the numerous benefits nature-based recreation provides. Results show that many people who do not participate in nature-based recreation feel constrained by their quality of time, not the quantity of time. In other words, they're saying, "Prove to me that it's worth my time to go out in nature. Show me something cool!" Based on research conducted in Hillsborough County, Florida and similar studies, this 6-page fact sheet written by Margaret E. Gullion and Taylor Stein and published by the UF/IFAS School of Forest Resources and Conservation addresses identifies strategies to improve the opportunities natural areas can provide a diverse public. https://edis.ifas.ufl.edu/fr415

This case study analyzes the potential impacts of weakening the National Park Service’s (NPS) “9B Regulations” enacted in 1978, which established a federal regulatory framework governing hydrocarbon rights and extraction to protect natural resources within the parks. We focus on potential risks to national parklands resulting from Executive Orders 13771—Reducing Regulation and Controlling Regulatory Costs [1]—and 13783—Promoting Energy Independence and Economic Growth [2]—and subsequent recent revisions and further deregulation. To establish context, we briefly overview the history of the United States NPS and other relevant federal agencies’ roles and responsibilities in protecting federal lands that have been set aside due to their value as areas of natural beauty or historical or cultural significance [3]. We present a case study of Theodore Roosevelt National Park (TRNP) situated within the Bakken Shale Formation—a lucrative region of oil and gas deposits—to examine potential impacts if areas of TRNP, particularly areas designated as “wilderness,” are opened to resource extraction, or if the development in other areas of the Bakken near or adjacent to the park’s boundaries expands [4]. We have chosen TRNP because of its biodiversity and rich environmental resources and location in the hydrocarbon-rich Bakken Shale. We discuss where federal agencies’ responsibility for the protection of these lands for future generations and their responsibility for oversight of mineral and petroleum resources development by private contractors have the potential for conflict.

Full textAbstract:
Abstract Snow density is calculated as a ratio of snow water equivalent to snow depth. Until the late 1990s, there were no continuous simultaneous measurements of snow water equivalent and snow depth covering large areas. Because of that, spatiotemporal characteristics of snowpack density could not be well described. Since then, the Natural Resources Conservation Service (NRCS) has been collecting both types of data daily throughout the winter season at snowpack telemetry (SNOTEL) sites located in the mountainous areas of the western United States. This new dataset provided an opportunity to examine the spatiotemporal characteristics of snowpack density. The analysis of approximately seven years of data showed that at a given location and throughout the winter season, year-to-year snowpack density changes are significantly smaller than corresponding snow depth and snow water equivalent changes. As a result, reliable climatological estimates of snow density could be obtained from relatively short records. Snow density magnitudes and densification rates (i.e., rates at which snow densities change in time) were found to be location dependent. During early and midwinter, the densification rate is correlated with density. Starting in early or mid-March, however, snowpack density increases by approximately 2.0 kg m−3 day−1 regardless of location. Cluster analysis was used to obtain qualitative information on spatial patterns of snowpack density and densification rates. Four clusters were identified, each with a distinct density magnitude and densification rate. The most significant physiographic factor that discriminates between clusters was proximity to a large water body. Within individual mountain ranges, snowpack density characteristics were primarily dependent on elevation.

Full textAbstract:
AbstractLoess is common in the Mid-Atlantic region of the United States south of the Late Wisconsinan glacial border particularly along rivers draining the glaciated areas of Pennsylvania, New Jersey, and New York. The broadest deposits occur on the flat landscapes of the Delmarva Peninsula in Maryland where two episodes of deposition have been identified. The earlier Miles Point Loess has a limited distribution and is buried by the more widespread Paw Paw Loess. OSL and 14C dates place deposition of the Miles Point Loess during MIS 3. The well developed paleosol formed in the Miles Point Loess acts as a stratigraphic marker. The Paw Paw Loess buries Clovis age cultural materials which date deposition to the end of the Pleistocene. Loess deposits and paleosols are critical in understanding regional landscape evolution, Late Pleistocene environments, and early North American cultural history. Mapping the extent of loess in the Mid-Atlantic using the Natural Resources Conservation Service’s gSSURGO database overrepresents loess in some areas and underrepresents in others.

Full textAbstract:
Butternut (Juglans cinerea L.) has many fine qualities as a nut species, however, it has never been commercially important. Although the nut is very edible, only a few cultivars have been selected that have desirable nut size and cracking qualities. In the last 20 years there has been a dramatic decline in the number of butternut in native stands caused to a large extent by the lack of natural reproduction and a damaging canker disease. Evidence suggests that superior, disease resistant trees can be propagated and if isolated from areas where the disease is prevalent, may remain disease-free. It is important that the remaining genetic diversity within the species is maintained. Various butternut conservation practices and research projects to restore butternut populations are underway in the United States and Canada.

Full textAbstract:
Abstract The United States Natural Resources Conservation Services Curve Number (NRCS-CN) method uses the CN and rainfall to calculate runoff. However, there are still some uncertainties in the method, such as choosing the most appropriate CN value. Therefore, this study attempts to evaluate the effectiveness of using the NRCS-CN method to estimate the runoff of five catchments in Sudan. For each catchment, CN values were obtained from the number of observed rainfall-runoff events using the NRCS table, arithmetic mean, median, and geometric mean methods. For each method, Nash–Sutcliffe efficiency (NSE) was obtained to evaluate the fit between the observed and runoff, and negative NSE values were found for all methods. Negative values of NSE indicate that the observed runoff and estimated runoff are not well fitted, and the NRCS-CN method is not suitable for runoff calculation in the study areas.

RESUMO A criação de unidades de conservação é considerada como principal ação de governo cujo objetivo é a preservação e conservação da biodiversidade. A delimitação de “áreas especiais” é uma prática observada desde as sociedades mais tradicionais, sendo que em muitas delas prevalecia um sentido mítico-religioso e, ao mesmo tempo, de conservação de recursos naturais. Em outras sociedades, essa ação esteve associada com a prática de esportes de caça por parte da realeza e da aristocracia rural. Os parques públicos começaram a surgir no século XIX nos Estados Unidos, numa perspectiva de preservação das belezas cênicas e proteção dos bens naturais contra a ação deletéria da sociedade. O tema em questão é discutido à luz da categoria geográfica de território e dos processos de territorialização, utilizando-se para esse fim suas múltiplas abordagens conceituais— biológica, ecológica e social. Discute-se no trabalho os problemas da desterritorialização, em ambos os sentidos (biológico e social), além da formação das redes empenhadas no processo de criação e gestão das unidades de conservação. Houve um esforço de trazer para essa discussão uma contribuição sobre o valor agregado à conservação da biodiversidade com base em princípios de uma nova disciplina - a Biologia da Conservação. O trabalho aborda ainda aspectos conceituais sobre as políticas públicas, em geral, e sobre a influência que elas têm, especificamente, sobre a problemática das unidades de conservação no Brasil.ABSTRACT The principal goal to create natural parks and biological reserves in the world is to promote the conservation of biodiversity.

Full textAbstract:
Research Highlights: We demonstrate a macroscale framework combining an invasibility model with forest inventory data, and evaluate regional forest exposure to harmful invasive plants under different types of forest protection. Background and Objectives: Protected areas are a fundamental component of natural resource conservation. The exposure of protected forests to invasive plants can impede achievement of conservation goals, and the effectiveness of protection for limiting forest invasions is uncertain. We conducted a macroscale assessment of the exposure of protected and unprotected forests to harmful invasive plants in the eastern United States. Materials and Methods: Invasibility (the probability that a forest site has been invaded) was estimated for 82,506 inventory plots from site and landscape attributes. The invaded forest area was estimated by using the inventory sample design to scale up plot invasibility estimates to all forest area. We compared the invasibility and the invaded forest area of seven categories of protection with that of de facto protected (publicly owned) forest and unprotected forest in 13 ecological provinces. Results: We estimate approximately 51% of the total forest area has been exposed to harmful invasive plants, including 30% of the protected forest, 38% of the de facto protected forest, and 56% of the unprotected forest. Based on cumulative invasibility, the relative exposure of protection categories depended on the assumed invasibility threshold. Based on the invaded forest area, the five least-exposed protection categories were wilderness area (13% invaded), national park (18%), sustainable use (26%), nature reserve (31%), and de facto protected Federal land (36%). Of the total uninvaded forest area, only 15% was protected and 14% had de facto protection. Conclusions: Any protection is better than none, and public ownership alone is as effective as some types of formal protection. Since most of the remaining uninvaded forest area is unprotected, landscape-level management strategies will provide the most opportunities to conserve it.

Full textAbstract:
Conservation and human rights are currently threatened by direct and indirect effects of border enforcement practices on the Arizona-Sonora border. Increased border enforcement in urban areas has pushed migrants into remote conservation areas, threatening both the vulnerable borderland ecosystems and the human migrants passing through them. This study examines responses to human and environmental impacts of border policies in the case study region of Altar Valley in southern Arizona, where migrant traffic has increased greatly as a result of the expanded border enforcement near urban centers. We use ethnographic methods to explore and understand the actions of land-management and humanitarian aid groups attempting to address the socio-ecological crises wrought by increased border enforcement, in order to look for ways to reduce the crises through a better understanding of the context. Community partners include the Buenos Aires National Wildlife Refuge, the Coronado National Forest, and the No More Deaths humanitarian aid group, all located within 25 miles of the Arizona-Sonora border. The results of this study, carried out largely during the summer of 2008, describe how the actions of land-management and humanitarian groups eventually conflicted and resulted in littering citations for the humanitarian aid volunteers who left water for migrants along trails on the wildlife refuge. The conflict was branded as an issue of conservation versus human rights. I argue that the conflict between land-management personnel and humanitarian aid volunteers arose not just from differing conservation and humanitarian goals, but from their different conceptions of problems associated with border activity and different ideas of the borderlands as a place.

This paper reviews the status of natural resources distance learning program in the United States and China and discusses the feasibility of educational cooperation between the two countries. By identifying and comparing computer-based learning programs offered at 300 American and 7 Chinese institutions of higher education, I found that only a small number of schools in both countries currently provide natural resources courses via distance learning. Although great opportunities exist for cooperation between the two countries, challenges must be overcome. Some of these challenges include expanding the existing distance learning curriculum to offer more natural resources courses, providing greater flexibility for faculty members who must adjust to a new teaching role, and improving the English proficiency of Chinese students for more effective international distance learning.Master of Natural Resources

Full textAbstract:
The American marten (Martes americana) is an endangered species in Vermont and a Regional Species of Greatest Conservation Need in the northeastern United States. Though historically widespread in northeastern forests, their range presumably contracted to northern Maine and the High Peaks region of the Adirondacks by the early 1900s. Regionally, populations appear to be in recovery. Natural recolonization is believed to have occurred in New Hampshire, northeastern Vermont and the western Adirondacks. A reintroduction effort in southern Vermont that was originally declared unsuccessful is now believed to be the source of a recently detected population in the area. However, our current knowledge of distribution, population history and population connectivity relies primarily on occurrence data from harvest records, which are limited in scope and resolution. In Vermont, where population size is estimated to be extremely low, more robust estimates of population status may be critical to continued recovery.
I genotyped individuals from Maine, New York, New Hampshire, northeastern Vermont and southern Vermont at ten microsatellite loci and amplified a 320 base pair segment of the control region of mtDNA to estimate the source(s) of the two Vermont populations using statistical tests of genetic differentiation. I also used Bayesian and stochastic genetic clustering methods to estimate population genetic structure in the northeastern United States. Genetic structure exists at multiple scales in the region as a result of natural barriers to gene flow, human-mediated gene flow, and lineage sorting in relic populations. My results suggest that New Hampshire is a major source of colonization of northeastern Vermont and the population in southern Vermont is either a remnant of the reintroduction or a pre-reintroduction relic that has experienced introgression from the reintroduction stock. I identified three regions where relic populations perceived to be extirpated in the 1900s may have persisted.
I also developed an occupancy model for American marten in the northeastern United States using mixed-effects logistic regression based on expert opinion data. Eighteen experts from Maine, New Hampshire, Vermont and New York with backgrounds in trapping, wildlife management, and wildlife science participated in the survey. Experts were asked to estimate the probability of marten occupancy at 30 sites in the northeastern United States. Three top models described the data. Habitat covariates in those models were 1) percent canopy cover, 2) percent spruce-fir forest cover, 3) winter temperature, 4) elevation, and 5) road density. An AIC-weighted average of these three models had significant predictive ability (area under an ROC curve = 0.88) with respect to occurrence records in the northeastern United States. In addition, the model predicted that high quality habitat existed patchily along the central and northern Green Mountain spine in Vermont – where no occurrence records exist for at least a century. Top-scoring movement corridors between southern Vermont and nearby populations in northeastern Vermont/New Hampshire and New York occurred in the northern and central Green Mountains and across high resistance movement barriers in the Champlain valley. Corridors to New York were considered strong movement barriers and are unlikely to facilitate gene flow.

The projected growth in human population, rapid urbanization, and expansion of structures like highways and canals pose a major threat to the future survival of wildlife, particularly large terrestrial mammals. In many cases, wild animal populations have been restricted to fragmented habitat islands due to anthropogenic developments, endangering them to local extinction. Current and future wildlife conservation and management strategies are leading to the implementation of mitigation measures such as creation of wildlife habitat corridors. In this light, novel and interdisciplinary research methods such as approaches in the field of landscape genetics are proving to be increasingly useful and necessary for assessing the status of wildlife populations and furthering efficacy of conservation programs and management efforts. In this 5-year research study, I review literature in the field of landscape genetics, highlighting studies and their applications toward wildlife conservation over the past decade (2005-2014). I then use a landscape genetic approach to understand the potential impact of natural and human-made barriers in and around the northern Sonoran Desert on one of the widest-ranging mammals in the world, the mountain lion (Puma concolor). I employ recently developed genetic tools to assess the current population genetic status of mountain lions in this region and Geographic Information Systems (GIS) tools to relate observations to landscape features through interpretive maps. I further investigate the utility of GIS and expert-based models in connectivity conservation and suggest validating them with information on genetic relatedness and functional connectivity among mountain lions. Lastly, in many parts of this document, I emphasize the use of these methods and data sharing in conservation planning as well as wildlife management.

Full textAbstract:
Public participation can fundamentally improve natural resources planning and decision-making. On an ad hoc basis, it has been shown that public participation improves the durability and sustainability of plans and decisions; it increases the technical, consensus-building, and decision-making capacity of the public; it increases levels of trust; and it improves relationships between agency personnel and members of the public. Despite the proliferation of these new tools and strategies and their successful implementation, innovative and inclusive public participation methods have still not become widely integrated into the natural resources planning and administrative decision-making processes of federal agencies. Utilizing the Bureau of Land Management's Western Oregon Plan Revision process as a case study, this paper considers barriers to the regular inclusion of innovative and inclusive public participation methods in agency's planning and decision-making processes and provides some prescriptions for overcoming those barriers. Through analysis of this case study, I identify eight potential roadblocks to integrating innovative forms of public participation in natural resources planning and decision-making, including: 1) political context, 2) the purpose and need of the planning effort, 3) false expectations for public involvement, 4) geographic scope of the planning area, 5) the plan timeline, 6) federal budgetary pressure, 7) agency culture and individual attitudes towards public participation, and 8) the limitations of leadership

Full textAbstract:
The principal response of the global community to the threats against biodiversity has been the establishment of strictly protected areas, exemplified by the National Park System of the United States. In such areas, consumptive uses are banned and wild nature is allowed to exist in untrammeled form. Nonconsumptive recreational uses—such as sightseeing, hiking, swimming, boating, and camping—are permitted but are regulated as to place and time and number of participants. In the tropical forest realm, however, protected nature preserves are in a state of crisis. A number of tropical parks have already been degraded almost beyond redemption; others face severe threats of many kinds with little capacity to resist. The final bulwark erected to shield tropical nature from extinction is collapsing. The predictable and unpredictable ecological processes likely to affect the future ability of protected rain forest areas to retain their full biodiversity are examined in chapter 3. While the potential impact of ecological processes could be severe, they are amenable to technical solutions and could be solved given sufficient resources and knowledge. A far more immediate and significant threat is posed by human activities. Indeed, the crisis of parks in the tropics results primarily from increasing human pressure on all unexploited natural resources, aggravated by ineffective protection. Pressure on parks is exerted on local, regional, and national scales, usually taking the form of illegal land appropriation or resource extraction. The attack on tropical parks is being pressed by four main classes of actors: local and displaced populations of agriculturalists and extractors, governments, resource-robbing elites, and (in a few cases) indigenous forest-dwelling populations. In this chapter, we discuss the root causes of the actions of each of these groups and of the institutional failure that results in ineffective enforcement of park legislation. many common themes, regardless of the geographic area to which they pertained, and one theme in particular stood out: despite legal status and the presence of conservation officers, protected areas are not safe from illegal appropriation and exploitation. Our perception is that the threat to tropical parks is not widely appreciated.

<em>Abstract</em>.—Nonpoint source pollution in the form of stormwater runoff is one of the most important emerging threats to ecosystems along the coastal margins of the United States. A wide diversity of potentially toxic chemicals is commonly found in stormwater. These include the various pesticides, petroleum hydrocarbons, heavy metals, and other common contaminants that originate from commercial, industrial, residential, and agricultural land-use activities. These chemicals are mobilized from roads, lawns, crops, and other surfaces by rainfall and then transported to aquatic habitats via terrestrial runoff. The ongoing development of coastal watersheds nationwide is increasing the loading of nonpoint source pollutants to rivers, estuaries, and the nearshore marine environment. A central aim of the National Oceanic and Atmospheric Administration’s national Coastal Storms Program (CSP) is to enhance the resiliency of coastal ecosystems by improving the ability of coastal communities to anticipate and reduce the impacts of contaminated terrestrial runoff. Toxic chemicals in stormwater can adversely impact the health of fish, including threatened and endangered species. Nonpoint source pollution can also degrade the biological integrity of aquatic communities that support productive fish populations. This article examines the effects of stormwater runoff on fish and fisheries. Using case studies drawn from CSP project work in the Pacific Northwest and Southern California pilot regions, we show how degraded water quality can impact the health of fish during critical life history stages (i.e., spawning and rearing) as well as limit the overall effectiveness of fish habitat restoration. We also discuss some of the resources currently available to local communities to reduce the loading of toxics in stormwater, thereby increasing the resilience of aquatic communities. Finally, we identify priority areas for new research to help guide the future conservation and recovery of at-risk fish populations.

<em>Abstract</em>.—In support of the Magnuson–Stevens Conservation and Management Reauthorization Act of 2006, which tasked regional fisheries management councils with ending overfishing of numerous marine finfish species, the South Atlantic Fisheries Management Council established 8 deepwater (90–150 m [300–500 ft]) type II marine protected areas (MPAs) along the coastline of the southeastern United States. At the request of the South Carolina Department of Natural Resources (SCDNR), one of these MPAs was established on an undeveloped sand-bottom area previously permitted by SCDNR for artificial reef development. After monitoring the production potential of unfished artificial reefs for several years on shallower experimental reef sites, SCDNR staff proposed that a deeper location had the potential to become a highly productive spawning site, particularly for deepwater grouper species. Development of this permitted site began in 2014 when two 79-m (260 ft) barges with nearly 30 m (100 ft) of added profile were deployed. Subsequent monitoring of the site through remotely operated underwater vehicle video revealed colonization by several target species, including Warsaw Grouper <em>Hyporthodus nigritus</em>, Snowy Grouper <em>H. niveatus</em>, and Misty Grouper <em>H. mystacinus</em>. Due in part to the success of this deepwater MPA, the SCDNR was also granted spawning special management zone designation for its two previously established, undisclosed experimental artificial reef sites in federal waters off South Carolina in 2017.

Full textAbstract:
The Mojave Desert in the southwestern United States is one of the hottest and driest areas of North America. Climate change is likely to exacerbate these conditions. The region is home to many endemic plant species, including 24 federally threatened species. The impact of climate change factors on these sensitive Mojave Desert species is relatively unknown. Here we used a climate change vulnerability assessment to determine which imperiled plants may be most affected by changing climatic conditions. We evaluated the vulnerability of each species under future climate scenarios and calculated scores using metrics such as exposure, sensitivity, niche breadth, and dispersal capability. We found that most listed plant species were vulnerable to climate change, with 21% (N = 5) classified as extremely vulnerable, 25% (N = 6) classified as highly vulnerable, and 42% (N = 10) classified as moderately vulnerable. Contributing factors most frequently associated with vulnerability included various barriers to migration, high habitat specificity, and species sensitivity to changes in hydrological patterns. Many of these species are already threatened by ongoing anthropogenic stressors such as urban growth and associated developments, and these results suggest that climate change will pose additional challenges for conservation and management. Natural resource managers can use the vulnerability ranking and contributing factors identified from these analyses to inform ecological decisions related to threatened plants throughout desert regions.

<em>Abstract.—</em>As the United States has become increasingly urbanized, angling participation has declined. Urban fishing programs provide an opportunity to reverse this trend by effectively targeting new anglers while increasing fishing opportunities for current or recently lapsed urban anglers. There are three essential components in a successful urban fishing program: a resource with clean water and a quality fishery close to current or potential anglers, facilities to accommodate anglers, and advertisement of the fishery to inform and recruit anglers. Early in the development of an urban fishing program, urban anglers’ interests should be assessed and the program should be developed to meet these interests. Next, access to a quality fishery must be developed—either by creating new bodies of water or enhancing existing ones. Depending upon the level of fishing pressure and the species of interest to anglers, supplemental stocking and intensive management may be needed to maintain the fishery. Amenities such as restrooms, picnic areas, docks, and waste receptacles may also be important. Different angling groups may desire different amenities, so providing different sites to cater to these different groups is advisable. Once the facilities and amenities are in place, the resource must be marketed to targeted potential anglers. The marketing strategy should be tailored to each market segment being targeted. Lapsed anglers are the most easily recruited segment and should be a top priority for advertising. Minorities and children are also commonly targeted. As the U.S. population becomes more urbanized, urban fishing opportunities will continue to grow in importance. Without these opportunities, urbanites will likely be drawn toward the numerous other recreational activities that are conveniently available in urban centers, leading to further declines in angling involvement and concern for natural resource conservation and the environment.

Chapter 13 reviews the policies and instruments applied by governments to the conservation of natural capital in areas of national jurisdiction. Measures addressed include the assignment of property rights in biological resources; protective legislation; environmental offsets; incentive systems including taxes, subsidies, and payments for ecosystem services; and penalties. Particular attention is paid to common pool resource management regimes, legal restrictions on land use such as the US Endangered Species Act, biodiversity offsets, and payment systems such as the EU and US agri-environment schemes.

Full textAbstract:
Protagonists of global environmental governance often view the sovereign State as well as the principle of sovereignty as major stumbling blocks for effective environmental conservation and sustainable development. Some even herald the demise of the idea of the sovereign State. However, reality has it differently. Sovereignty is no longer an unqualified concept. Manifold new duties have been imposed upon the sovereign State as a result of the progressive development of international law. Much of the modern international law movement vests States with the responsibility to adopt regulations, to monitor and secure compliance and exercise justice in order to achieve its implementation, whereas supranational global environmental governance has remained notoriously weak. This article examines this proposition by reference to the environmental and developmental role of states in three landmark multilateral treaties: The United Nations Law of the Sea Convention (1982), the Convention on the Conservation of Biological Diversity (1992) and the Paris Agreement on climate change (2015). They demonstrate that sovereignty serves as a key organisational principle for the realization of global values, such as environmental conservation and sustainable development.

Full textAbstract:
In the remaining chapters we will focus increasingly on the response by colonized people to competition for, and commodification of, conquered environments. Political conflict over natural resources had deep historical roots in the Empire, and these issues were not resolved by dominion status for the British settler states nor decolonization after the Second World War. They fed into the politics of decolonization and into environmental debates within and beyond the post-colonial Commonwealth. Subsequent chapters traverse the moment of decolonization and explore elements of late twentieth-century political ecology. In South Asia and Africa state attempts to control and regulate natural resources changed power relations in the countryside and triggered popular resistance. Through conquest or annexation, some colonial and protectorate governments not only alienated large swathes of territory, but also assumed responsibility for and asserted rights over the natural environment. The governments of settler states moved to protect environments from careless settlers who ransacked it for wildlife or timber, and from indigenous peoples whose land-management systems were regarded as destructive. In some cases conservators recognized that European settlers wreaked more havoc than indigenes; Sim said of the Cape forests that the ‘Hottentot and Bushman inhabitants … were not intentionally destructive … But the advent of European civilization boded greater ill to the forests, and rapidly enough that ill has been accomplished.’ And some, such as Howard, saw value in local agrarian systems. But although regulation could affect all colonial subjects, it tended to bear most heavily on indigenous people. Colonial governments introduced policies of excluding humans from protected areas, as well as a wide range of other measures aimed at curbing customary user rights and maximizing state revenue. Stiff penalties were introduced to punish those who broke the new regulations, and thus the rise of bureaucratic conservationism often led to the criminalization of local resource extractors. In settler colonies the privatization of land transformed socio-environmental relationships, barring local communities from accessing resources they had long regarded as communally held and managed. In some early colonial settlements, this process echoed the enclosures of common land in eighteenth-century England. At a fundamental level it changed the value people placed upon land, setting in train a process towards individualized tenure, commercialization, and subdivision of territory.

Abstract Two hundred sixty-nine regulated pipeline system accidents caused fatalities and/or injuries in the United States between 2010 and 2018, resulting in 106 fatalities and 599 injuries requiring hospitalization. About 84% of these serious accidents occurred on gas distribution systems, which primarily transport natural gas. This study adapts probabilistic risk assessment (PRA) methods which are used predominantly in the space and nuclear industries to gas distribution systems in the U.S. Nationwide system and accident data are used to evaluate natural gas distribution system risks, estimate how many additional resources the public would be willing to dedicate to reduce or eliminate these risks, and determine which improvement areas warrant further evaluation. Recommendations regarding the overall PRA-based framework, as well as the scope, quality, and level of detail of the underlying data, are provided.

ABSTRACT In the midst of aggressive anti-drilling campaigns by environmental organizations and well-publicized complaints by citizens unaccustomed to oil and gas operations, rigorous studies of unconventional oil and gas development show that there are no widespread or systemic impacts on drinking water resources in the United States. In addition, air pollution and greenhouse gas emissions have significantly declined with the growth in natural gas production and its use in power generation. Furthermore, induced seismicity from subsurface waste disposal has plummeted in response to industry initiatives and new regulations. This record of environmental protection reflects the fact that U.S. hydraulic fracturing, like other oil and gas operations, is highly regulated by the states. In addition, air emissions, operations on federal lands, and subsurface injection are subject to federal regulation. Academic and government researchers have documented that chemicals and gas produced by hydraulic fracturing are not contaminating drinking water. However, as an added complication, methane occurs naturally in drinking water aquifers in some producing areas. In 2015, the U.S. Environmental Protection Agency (EPA) completed a four-year study of potential aquifer contamination from hydraulic fracturing and associated industry operations. The report found some impacts on drinking water including contamination of drinking water wells; however, the number of cases was small compared to the number of wells hydraulically fractured. The scientific peer-review and public critique of the study, which continues after more than a year, may recommend additional research. The emotionally charged, anti-fracking campaigns provided important lessons to U.S. operators: pre-drilling, baseline data on water and air quality are essential to answering public concerns; infrastructure issues such as increased truck traffic on small, local roads are important to residents; and the initial failure to disclose the composition of hydraulic fracturing fluid intensified public concern.

Understanding where, when, and how conditions are changing along the extent of an energy pipeline system, which can be vast, is a challenging task. The challenge can be even greater when natural disasters1 create a condition where access to affected pipelines, qualified personnel, and equipment is limited. To address these challenges, pipeline operators are working directly with experts in satellite technology to develop innovative applications incorporating the use of satellite technology and analytical processes to improve natural disaster monitoring and response. Through recent experiences following Hurricane Harvey in the Gulf Coast region of the United States in August-September 2017 and the wildfires and mudslides in Southern California that occurred in December 2017 to January 2018, space-borne Synthetic Aperture Radar (SAR) satellite data was shown to be a useful tool for wide-area monitoring. Satellite-based SAR imagery has the unique advantage of penetrating through cloud cover and smoke and is capable of providing an early view of the extent of damage in both conditions. Satellite data and continuous improvements to their derived analytical products have resulted in significant benefits for pipeline operators preparing for and responding to the effects of potentially damaging natural processes, including river scour, erosion, avulsion, mudslides, and other threats to pipeline integrity and public safety. SAR change detection algorithms and processes can provide effective results in identifying areas affected by natural disasters that are not readily available by other means. These methods also provide timely information for allocating and directing resources to the most critical locations in support of post-disaster assessment and analysis. SAR satellite data and Amplitude Change Detection (ACD) algorithms provided the basis for confirming where flooding near pipeline infrastructure was most substantial following Hurricane Harvey. In the case of the Southern Californian forest fires and mudslides in Ventura and Santa Barbara counties, recent investigations into ACD and Coherence Change Detection (CCD) algorithms showed promising results, providing a detailed view of damaged areas in near-real time. This paper describes the process of collecting, analyzing, and applying satellite data for assessing the impacts of natural disasters on pipeline infrastructure, and the methods applied, consisting primarily of multiple change detection algorithms, that are used to process the large volume of satellite archive images to extract relevant changes. This paper also describes how these tools and products were practically applied to support decisions by pipeline operators to protect and ensure the integrity and safety of pipelines in the affected areas.

Full textAbstract:
The inventory, evaluation and treatment of cultural resources represent a significant challenge for siting and permitting natural gas pipelines. Project sponsors assist the Federal Energy Regulatory Commission’s Office of Energy Projects with meeting its obligations under Section 106 of the National Historic Preservation Act. The increasing sophistication of compliance with Section 106 is reflected in the Office of Energy Project’s 2002 Guidelines for Reporting on Cultural Resources Investigations for Pipeline Projects. Recent pipeline projects in the United States have involved environmental study corridors that are both wide and extensive, a combination that results in the identification of large numbers of cultural properties. The process of cultural resources management begins in the project planning stage with the development of site location modeling, analysis of previous investigations within or near Areas of Potential Effect, and consideration of the likelihood for encountering potentially eligible National Register of Historic Places properties. Using this information, site detection survey strategies can be developed that intensively target only sensitive portions of the Area of Potential Effect. During the survey, identification of archaeological sites, historic structures, or cultural landscapes requires prompt evaluation of National Register eligibility status for the purposes of avoidance or development of treatment plans. This presentation considers the Section 106 compliance process and how project sponsors can effectively manage cultural resources to ensure cost effectiveness and maintenance of restricted project schedules, while meeting the objectives of the National Historic Preservation Act.

Full textAbstract:
Solar energy is the largest energy resource on the planet. Unfortunately, it is largely untapped at present, in part because sunlight is a very diffuse energy source. Concentrating solar power (CSP) systems use low cost reflectors to concentrate the sun’s energy to allow it to be used more effectively. Concentrating solar power systems are also well suited for large solar power plants that can be connected into the existing utility infrastructure. These two facts mean that CSP systems can be used to make a meaningful difference in energy supply in a relatively short period. CSP plants are best suited for the arid climates in the Southwestern United States, Northern Mexico, and many desert regions around the globe. A recent Western Governors’ Association siting study [1] found that the solar potential in the U.S. Southwest is at least 4 times the total U.S. electric demand even after eliminating urban areas, environmentally sensitive areas, and all regions with a ground slope greater than 1%.While it is currently not practical to power the whole county from the desert southwest, only a small portion of this area is needed to make a substantial contribution to future U.S. electric needs. Many of the best sites are near existing high-voltage transmission lines and close to major power load centers in the Southwest (Los Angeles, Las Vegas, and Phoenix). In addition, the power provided by CSP technologies has strong coincidence with peak electric demand, especially in the Southwest where peak demand corresponds in large part to air conditioning loads. Parabolic troughs currently represent the most cost-effective CSP technology for developing large utility-scale solar electric power systems. These systems are also one of the most mature solar technologies, with commercial utility-scale plants that have been operating for over 20 years. In addition, substantial improvements have been made to the technology in recent years including improved efficiency and the addition of thermal energy storage. The main issue for parabolic trough technology is that the cost of electricity is still higher than the cost of electricity from conventional natural gas-fired power plants. Although higher natural gas prices are helping to substantially reduce the difference between the cost of electricity from solar and natural gas plants, in the near-term increased incentives such as the 30% Investment Tax Credit (ITC) are needed to make CSP technology approach competitiveness with natural gas power on a financial basis. In the longer term, additional reductions in the cost of the technology will be necessary. This paper looks at the near-term potential for parabolic trough technology to compete with conventional fossil power resources in the firm, intermediate load power market and at the longer term potential to compete in the baseload power market. The paper will consider the potential impact of a reduced carbon emissions future.

When people talk about the Metropolitan Area (MA), they mean differently in different parts of the world with different contexts. Based on its spatial extent, internal structure, socio-economic function, and network characteristics, an MA can refer to various entities from a metropolis to a Megacity-region. In an effort to clarify the MA concept, we review the origin of the MA concept and its development in various parts of the world, especially the United States, Japan and China, so as to propose a spectrum of MAs, and their relationship with specific human and natural geographical contexts. Particularly, we find MAs in China typically have a unique three-circle structure, which is composed of a core circle, a commuting circle, and a functional metropolitan circle. By international comparable standards which include factors such as population density, facility density, and economic activity intensity, and adjusted with reasonable context-dependent considerations in China, the three circles are designated as follows: the spatial extent with the highest development intensity and assuming a central regional role is identified as the core circle; the districts and counties around the core circle with a commuting rate greater than 10% are identified as the commuting circle; and the districts and counties within an one-hour accessible zone are identified as the functional metropolitan circle. To test the model, we utilize eight sources of big data covering ecological background, population, economy, transportation, real estate, land use, infrastructure, and culture characteristics, and with a fusion analysis of the data we show how the factors combined give rise to the three-circle structure in typical Chinese MAs, and why the combination of the same factors in the US and Japanese contexts works otherwise to fill different niches in the spectrum of MAs mentioned above. For a further inquiry, within the framework of the same model and using the same dataset, we identify 32 cities from all 338 prefecture-level cities in China that would qualify as an MA or potential MA, which we call “the Metropolitan Areas with Chinese Characteristics”, and designate the spatial extent of the three circles within each of the MAs. Additional analyses are also conducted to locate the main development corridors, key growth poles, and currently underdeveloped regions in each of the MAs. We conclude the paper with discussions of potential challenges of MA development in China vis-a-vis current policies, such as cross-administration collaboration between jurisdictions within the same MA, and cross-scale collaboration between MAs, cities, and city groups. Placing the research in the global context, and considering the vast similarities between China and other developing countries in terms of population density, land resources, urbanization level, and socio-economic development status in general, we argue that China’s model of MAs may be also applicable to other developing countries. Therefore, this research may shed lights to planning researchers and practitioners around the world, especially in developing countries in understanding the development conditions of MAs in their own contexts, and also in methods for identifying and planning potential MAs to achieve their specific policy objectives.

Full textAbstract:
Southern California and Baja California share, besides a dynamic social and economic exchange and 226 kilometers of borderline, an important natural resource: water from the Colorado River. Both areas have arid and semiarid climate in large zones and local fresh water sources are scarce, so water imports from the Colorado are strategic for their continued social and economic growth. Southern California’s water supply comes from the State Water Project, the Colorado River Aqueduct and local sources; in turn, Baja California depends mostly on the water supplied by the Colorado River, with an aqueduct that serves the Pacific coastline cities of the state. Both water supply systems are considered high energy consumers, affecting the quality of life in the region. The sustainable development of both communities is a challenge to Mexican and American public policy planners who must recognize that, to meet the future water demands to support sustainable development in this area it will require improved utilization and management of water resources. In this paper, water supply sustainable indicators were calculated for southern California and Baja California to evaluate and compare their performance towards sustainability. Findings show big differences in the indicators like water use per person, percentage of the cost of water relative to household income, cost of electricity to convey water, etc. High contrast in both economies makes up for these differences, but as water stakeholders of an only source, that is, the Colorado River, Mexico and the United States should avoid those imbalances in water use and management efficiencies, as it might affect its availability and cost, bringing potential conflicts and disturbing the traditional friendly coexistence and growth of both communities.

Full textAbstract:
Geologic hazards pose a significant threat to pipeline integrity. As an existing pipeline system ages, targeted analysis and positioning of maintenance resources become increasingly important to remediating problem pipeline sections and to ensure timely response to system failures. A geographic information system (GIS) now is commonly used to model pipeline systems. Significant geologic hazards can be mapped and effectively managed in a GIS database as a way to assess risk and to target pipeline remediation resources. In particular, the potential for soil corrosion is a significant threat to pipelines. In the U.S., digital soil maps from the United States Department of Agriculture, Natural Resources Conservation Service (USDA NRCS) have been compiled into the Soil Survey Geographic (SSURGO) database. Numerous soil attributes are stored in the database allowing for a detailed examination of soil characteristics. SSURGO data is largely consistent in quality and geographic extent across the U.S. and is the best available database for a national assessment of soil corrosion potential. We describe the development of a national database for the collection of locations of known corrosion from pipeline system managers. This database can be compared to soil conditions, as noted in SSURGO or other supporting soil data, for the development of a model of soil parameters that may indicate the future potential for buried pipeline corrosion. This paper outlines the need for such a database, significant design considerations and the proposed process for model development.

Full textAbstract:
Abstract Railroad tank car transportation is the most efficient way to transport large amounts of hazardous material. More than 2 million tank-car loads of hazardous materials (hazmat) are transported annually by rail in the United States. Recently, the boom in the production of petroleum crude oil and natural gases from shale has dramatically increased the rail transport volume of flammable energy resources. However, accidents do occur, and the transportation of flammable hazardous material can result in disastrous consequences. The fire can heat up a tank car, rapidly increasing the inside pressure and causing the tank car to either rupture or explode. Railroad companies are developing or seeking advanced thermal protection systems to prevent tank car explosion or prolong the burst time to win a sufficient rescue time. It is of great importance to understand the existing thermal protection systems used in hazmat tank cars and to identify key priorities that the government and industry consider for improving tank car thermal protection performance, providing guidance for future thermal protection material development. Thus, this paper reviews the literature on the effects and analysis of different tank car thermal protection systems, identifying the effectiveness of different thermal protection components, properties of thermal protection materials, and testing methodologies. Different combinations of insulators and jackets are tested in order to observe the effects of the fire on the tank car. The tank car is tested while carrying hazardous material like liquefied petroleum gas, propane, and ethylene oxide, etc. This investigation analyzes the differences of thermal protection systems in prolonging the life span of a tank car engulfed in flames. A tank car can use either material like fiberglass, ceramic fiber blankets, perlite powder, or urethane foam to better insulate and thermally protect the tank car. An insulator is shown to prolong the life span of a tank car since bare tank cars tend to heat up rapidly when exposed to flames. The thermal protection system of a tank car is built of insulators, jackets, and supporting material for the insulator. The supporting material and jacket combination with the insulator also prevent the tank car from heating up rapidly. There are two primary testing methods, pool fire, and torch fire. Each type of fire has different outcomes and limits in which the tank car can withstand. When testing the heating of a tank car, thermocouples were placed throughout a tank car and recorded to check what areas were heated the most during the experiment. Some factors that had been accounted for in the previous studies were the wind speed and the direction of the wind, which affected the overall experiment, mostly torch fire experiments.

Full textAbstract:
Aim/Purpose: In the United States, the Centers for Disease Control and Prevention (CDC) tracks the disease activity using data collected from medical practices on a weekly basis. Collection of data by CDC from medical practices on a weekly basis leads to a lag time of approximately 2 weeks before any viable action can be planned. The 2-week delay problem was addressed in the study by creating machine learning models to predict flu outbreak. Background: The 2-week delay problem was addressed in the study by correlation of the flu trends identified from Twitter data and official flu data from the Centers for Disease Control and Prevention (CDC) in combination with creating a machine learning model using both data sources to predict flu outbreak. Methodology: A quantitative correlational study was performed using a quasi-experimental design. Flu trends from the CDC portal and tweets with mention of flu and influenza from the state of Georgia were used over a period of 22 weeks from December 29, 2019 to May 30, 2020 for this study. Contribution: This research contributed to the body of knowledge by using a simple bag-of-word method for sentiment analysis followed by the combination of CDC and Twitter data to generate a flu prediction model with higher accuracy than using CDC data only. Findings: The study found that (a) there is no correlation between official flu data from CDC and tweets with mention of flu and (b) there is an improvement in the performance of a flu forecasting model based on a machine learning algorithm using both official flu data from CDC and tweets with mention of flu. Recommendations for Practitioners: In this study, it was found that there was no correlation between the official flu data from the CDC and the count of tweets with mention of flu, which is why tweets alone should be used with caution to predict a flu out-break. Based on the findings of this study, social media data can be used as an additional variable to improve the accuracy of flu prediction models. It is also found that fourth order polynomial and support vector regression models offered the best accuracy of flu prediction models. Recommendation's for Researchers: Open-source data, such as Twitter feed, can be mined for useful intelligence benefiting society. Machine learning-based prediction models can be improved by adding open-source data to the primary data set. Impact on Society: Key implication of this study for practitioners in the field were to use social media postings to identify neighborhoods and geographic locations affected by seasonal outbreak, such as influenza, which would help reduce the spread of the disease and ultimately lead to containment. Based on the findings of this study, social media data will help health authorities in detecting seasonal outbreaks earlier than just using official CDC channels of disease and illness reporting from physicians and labs thus, empowering health officials to plan their responses swiftly and allocate their resources optimally for the most affected areas. Future Research: A future researcher could use more complex deep learning algorithms, such as Artificial Neural Networks and Recurrent Neural Networks, to evaluate the accuracy of flu outbreak prediction models as compared to the regression models used in this study. A future researcher could apply other sentiment analysis techniques, such as natural language processing and deep learning techniques, to identify context-sensitive emotion, concept extraction, and sarcasm detection for the identification of self-reporting flu tweets. A future researcher could expand the scope by continuously collecting tweets on a public cloud and applying big data applications, such as Hadoop and MapReduce, to perform predictions using several months of historical data or even years for a larger geographical area. *** NOTE: This Proceedings paper was revised and published in the journal Issues in Informing Science and Information Technology, 18, 63-81 At the bottom of this page, click DOWNLOAD PDF to download the published paper. ***

Wyndham, Amber, Emile Elias, Joel Brown, Michael Wilson, and Albert Rango. Drought Vulnerability Assessment to Inform Grazing Practices on Rangelands of Southeastern Colorado’s Major Land Resource Area 69. USDA Southwest Climate Hub, July 2018. http://dx.doi.org/10.32747/2018.6947062.ch.
Full textAbstract:
Increased climate variability, including more frequent and intense drought, is projected for the southwestern region of the United States. Increased temperatures and reduced precipitation lower soil water availability, resulting in decreased plant productivity and altering species composition, which may affect forage quality and quantity. Reduced forage quality and increased heat stress attributable to warmer temperatures could lead to decreased livestock performance in this system, which is extensively used for livestock grazing. Mitigating the effects of increasing drought is critical to social and ecological stability in the region. Reduced stocking rates, change in livestock breeds and/or grazing practices
are general recommendations that could be implemented to cope with increased climatic stress. Ecological Sites and their associated state–and-transition models (STMs) are tools to help land managers implement and evaluate responses to disturbances. The projected change in climate will vary depending upon geographic location. Vulnerability assessments and adaptation strategies are needed at the local level to inform local management decisions and help ameliorate the effects of climate change on rangelands. The United States Department of Agriculture (USDA) Southwest Climate Hub and Natural Resources Conservation Service (NRCS) worked together to produce this drought vulnerability
assessment at the Major Land Resource Area (MLRA) level, based on ecological sites and state-and-transition models that will help landowners and government agencies to identify and develop adaptation options for drought on rangelands. The assessment illustrates how site-specific information can be used to help minimize the effects of drought on rangelands and support informed decision-making for the selection of management adaptations within MLRA 69.

McDowell Peek, Katie, Blair Tormey, Holli Thompson, Allan Ellsworth, and Cat Hawkins Hoffman. Climate change vulnerability assessments in the National Park Service: An integrated review for infrastructure, natural resources, and cultural resources. National Park Service, June 2022. http://dx.doi.org/10.36967/nrr-2293650.
Full textAbstract:
Climate changes are affecting virtually all National Park Service units and resources, and an assessment of climate vulnerabilities is important for developing proactive management plans to respond appropriately to these changes and threats. Vulnerability assessments typically evaluate exposure and sensitivity of the assessment targets and evaluate adaptive capacity for living resources. Chapters in this report review and evaluate climate vulnerability assessments of National Park Service units and resources including infrastructure, natural resources, and cultural resources. Striking results were the diversity of approaches to conducting vulnerability assessments, the small number of vulnerability assessments for National Park Service cultural resources, and the large differences in the “state of the science” of conducting assessments among the three resource groups. Vulnerability assessment methodologies are well established for evaluating infrastructure and natural resources, albeit with very different techniques, but far less is known or available for designing and/or conducting cultural resources assessments. Challenges consistently identified in the vulnerability assessments, or the chapters were: Limited capacity of park staff to fully engage in the design and/or execution of the vulnerability assessments. Most park staff are fully engaged in on-going duties. Inconsistent use of terms, definitions, and protocols, sometimes resulting in confusion or inefficiencies. Discovering and acquiring National Park Service vulnerability assessments because results were inconsistently archived. Aligning results with park needs due to differences in level of detail, scope, and/or resolution, or format(s) for reporting results. Best practices and recommendations identified in multiple chapters were: Ensure that vulnerability assessments are designed to match parks’ needs, and that results are reported in ways that inform identified management decisions. Prioritize resources to be thoroughly assessed so effort is directed to the most important threats and resources. Evaluate all components of vulnerability (not just exposure). Explicitly and systematically address uncertainty, recognizing the range of climate projections and our understanding of potential responses. Identify and, where possible, focus on key vulnerabilities that most threaten conservation or management goals. Embrace partnerships and engage others with necessary expertise. Good vulnerability assessments usually require expertise in a broad range of subject areas.

Bradford, John, Caroline Havrilla, Jessica Hartsell, Daniel Schlaepfer, Molly McCormick, Seth Munson, Charles Yackulic, et al. Southeast Utah Group climate and drought adaptation report: Exposure and perennial grass sensitivity. National Park Service, July 2022. http://dx.doi.org/10.36967/2293951.
Full textAbstract:
National Park Service (NPS) managers face growing challenges resulting from the effects of climate change. In particular, as temperatures rise in coming decades, natural resource management in the western United States must cope with expectations for elevated severity and frequency of droughts. These challenges are particularly pronounced for vegetation managers in dryland environments. Developing adaptive strategies requires specific information about the expected magnitude of change in climate and drought conditions as well as insights into how those changes will affect important vegetation resources. This report describes research focused on Southeast Utah Group (SEUG) park units designed to provide information about exposure and sensitivity of perennial grasses to aridification. Analyses at larger regional scales are also reported for context and comparison. This report is a product of an ongoing climate adaptation collaboration between the U.S. Geological Survey (USGS), NPS, and Northern Arizona University. The study it summarizes contributes quantitative ingredients for vulnerability assessments that are needed in the Climate-Smart Conservation framework. As such, the results informed a series of climate adaptation workshops conducted between 2018 and 2021 for Colorado Plateau scientists and managers. This is a giant step forward in science-informed management. The information in this report can be used to craft management strategies that can be implemented at the right place and time for individual species of concern.

Taverna, Kristin. Vegetation classification and mapping of land additions at Richmond National Battlefield Park, Virginia: Addendum to technical report NPS/NER/NRTR 2008/128. National Park Service, September 2022. http://dx.doi.org/10.36967/2294278.
Full textAbstract:
In 2008 and 2015, the Virginia Department of Conservation and Recreation, Division of Natural Heritage produced vegetation maps for Richmond National Battlefield Park, following the protocols of the United States Geological Survey (USGS) – National Park Service (NPS) Vegetation Mapping Program. The original 2008 report was part of a regional project to map and classify the vegetation in seven national parks in Virginia. The 2015 report was an addendum to the original report and mapped the vegetation in newly acquired parcels. Since 2015, the park has acquired an additional 820 acres of land within 12 individual parcels, including the 650 acre North Anna unit. This report is an addendum to the 2008 and 2015 reports and documents the mapping of vegetation and other land-use classes for the 12 new land parcels at Richmond National Battlefield Park, with an updated vegetation map for the entire park. The updated map and associated data provide information on the sensitivity and ecological integrity of habitats and can help prioritize areas for protection. The vegetation map of the new land parcels includes eighteen map classes, representing 14 associations from the United States National Vegetation Classification, one nonstandard, park-specific class, and three Anderson Level II land-use categories. The vegetation classification and map classes are consistent with the original 2008 report. Vegetation-map classes for the new land parcels were identified through field reconnaissance, data collection, and aerial photo interpretation. Aerial photography from 2017 served as the base map for mapping the 12 new parcels, and field sampling was conducted in the summer of 2020. Three new map classes for the Park were encountered and described during the study, all within the North Anna park unit. These map classes are Coastal Plain / Outer Piedmont Basic Mesic Forest, Northern Coastal Plain / Piedmont Oak – Beech / Heath Forest, and Southern Piedmont / Inner Coastal Plain Floodplain Terrace Forest. The examples of Coastal Plain / Outer Piedmont Basic Mesic Forest and Southern Piedmont / Inner Coastal Plain Floodplain Terrace Forest at North Anna meet the criteria of size, condition, and landscape context to be considered a Natural Heritage exemplary natural community occurrence and should be targeted for protection and management as needed. New local and global descriptions for the three map classes are included as part of this report. Refinements were made to the vegetation field key to include the new map classes. The updated field key is part of this report. An updated table listing the number of polygons and total hectares for each of the 28 vegetation- map classes over the entire park is also included in the report. A GIS coverage containing a vegetation map for the entire park with updated Federal Geographic Data Committee (FGDC) compliant metadata was completed for this project. The attribute table field names are the same as the 2008 and 2015 products, with the exception of an additional field indicating the year each polygon was last edited.
