Résumé :
AbstractExotic aquatic plant management is a major concern for public reservoir management in many regions of the United States. A study was conducted to measure the effects of alternative aquatic plant management strategies on recreational expenditures and regional economic activity. The study area was Lake Guntersville, Alabama, and the local economy surrounding the lake. Lake Guntersville is one of the largest reservoirs in the Tennessee Valley Authority system. Results suggested that relatively moderate levels of aquatic plant control are associated with the highest levels of recreation-related economic effects on the economy surrounding Lake Guntersville.

Résumé :
The objective of this research is to determine the relationship between land use, particularly density, and per capita spending levels in cities across the United States. A model was developed using data from the U.S. Census Bureau’s Annual Survey of State and Local Government Finances to estimate the impacts of population-weighted density and other factors on per capita municipal spending. This study focused on municipal spending for eight categories that theoretically could be influenced by land use development: fire protection, streets and highways, libraries, parks and recreation, police, sewer, solid waste management, and water. Density was found to be negatively associated with per capita municipal expenditures for the following cost categories: operational costs for fire protection, streets and highways, parks and recreation, sewer, solid waste management, and water; construction costs for streets and highways, parks and recreation, sewer, and water; and land and existing facility costs for police, sewer, and water. Results were insignificant for other cost categories, and a positive relationship was found for police operations costs. In general, results support the conclusion that increased density is associated with reduced per capita municipal spending for several cost categories.

Résumé :
Abstract Increased emphasis on sustainable resource management in forestry has effectuated a demand for various nontimber values. Nonconsumptive wildlife recreation is an important nontimber service produced on forest and rangeland. Travel cost models and data from the 1991 National Survey of Fishing, Hunting and Wildlife-Associated Recreation are used to estimate the demand and value for nonconsumptive wildlife-associated recreation in the United States. Resulting welfare measures are shown to be sensitive to assumptions about the cost of travel time, pecuniary costs, and functional form. Consumer surplus estimates range from 18.7 to 327.5 dollars per trip, while aggregate estimates of consumer surplus resulting from access to nonconsumptive wildlife recreation range from 5.8 to 66.4 billion dollars annually. Availability of information about nonparticipants allows comparison of truncated and untruncated demand models. Contrary to previous findings, consumer surplus estimates from truncated models are smaller than for untruncated counterparts. Trip demand is found to be adversely affected by per capita decreases in forest and rangeland. Models include interaction variables to avoid forcing hunting or fishing as potential substitutes for the large number of people who do not hunt or fish. Hunting and nonconsumptive wildlife recreation are complementary activities, while the results for fishing are mixed. FOR. SCI. 46(4):496–506.

Résumé :
Risk management is an issue that has been previously addressed in recreation and athletic professions. The litigious nature of today's society requires that risk management procedures and policies be in place in recreation and athletic facilities. An institution that has implemented risk management procedures will better protect itself from costly litigation. This article is a follow-up to a 1997 article by Mulrooney & Green that discussed the overall risk management process and presented a risk management paradigm for recreational sport facilities. The purpose of this study was to examine college recreation facilities to elucidate if risk management procedures were in place in light of Spiegler v. State of Arizona (1996). This case resulted in a $5,000,000 verdict for the plaintiff, a result that might have been avoided with a properly developed and implemented risk management program. The study also examined the importance administrative personnel placed on having a risk management policy, and to what degree risk procedures and risk management training were implemented. A questionnaire designed and validated for utilization in a previous study was sent to 178 Division 1 universities throughout the United States. One hundred and twenty-three respondents completed and returned the survey. Based upon the results of the study, it is evident that the importance of risk management and its impact on liability reduction has not reached the administration of campus recreation and sport programs.

Résumé :
Federal wildland fire management policy in the United States directs the use of value-based methods to guide priorities. However, the economic literature on the effect of wildland fire on nonmarket uses, such as recreation, is limited. This paper introduces a new approach to measuring the effect of wildfire on recreational use by utilising newly available long-term datasets on the location and size of wildland fire in the United States and observed behaviour over time as revealed through comprehensive National Park Service (NPS) visitor data. We estimate travel cost economic demand models that can be aggregated at the site-landscape level for Yellowstone National Park (YNP). The marginal recreation benefit per acre of fire avoided in, or proximate to, the park is US$43.82 per acre (US$108.29 per hectare) and the net present value loss for the 1986–2011 period is estimated to be US$206 million. We also estimate marginal regional economic impacts at US$36.69 per acre (US$90.66 per hectare) and US$159 million based on foregone non-resident spending in the 17-county Great Yellowstone Area (GYA). These methods are applicable where time-series recreation data exist, such as for other parks and ecosystems represented in the 397-unit NPS system.

Résumé :
There has been extensive research on the association between environmental attitudes and outdoor recreation (or nature-based leisure activities) since the 1970s. There is now considerable evidence to support the claim that spending time in nature leads to greater connectedness to nature and thereby greater pro-environmental attitudes and behavior. However, there is an absence of research focused specifically on the association between outdoor recreation and concern for climate change, which is arguably the most pressing environmental problem facing the world today. We build on previous research by using the 2021 General Social Survey and structural equation modeling to analyze the association between frequency of engaging in outdoor recreation and concern for climate change among adults in the United States, with special attention to the role of enjoying being in nature. Controlling for other factors, we find that frequency of outdoor recreation has a positive, significant effect on climate change concern, but only indirectly via enjoyment of nature. Individuals who more frequently engage in outdoor recreation activities tend to report a greater sense of enjoyment of being outside in nature, and this enjoyment of nature is associated with a higher level of concern for climate change.

Résumé :
This qualitative study of representative bureaucracy examines the extension and limitations of liberal democratic rights by connecting environmental and social history with policy, individual decision making, gender, race, and class in American history. It documents major cultural shifts in a homogeneous patriarchal organization, constraints, advancement, and the historical agency of women and minorities. "Creating a Multicultural Forest Service" identifies a relationship between natural and human resources and tells a story of expanding and contracting civil liberties that shifted over time from women and people of color to include the differently-abled and LGBT communities. It includes oral history as a key to uncovering individual decision points, relational networks, organizational activism, and human/nature relations to shape meaningful explanations of historical institutional change. With gender and race as primary categories, this inquiry forms a history that is critical to understanding federal bureaucratic efforts to meet workforce diversity goals in natural resource organizations.

Résumé :
There are two prevailing views today about our forests and natural resources. Both views are considered the "right" view, each position comprising a set of values by which we make decisions and choices about using our natural resources. The "dominant world view," is anthropocentric and agriculturally based, with a strong belief that we can "fix" environmental problems through the use of technology. The key result of this view is a belief in the efficiency of economic expansion and its continued growth. The second view maintains we are part of nature, not masters of it, and that we have developed an arrogant attitude toward nature, believing we have the right to do as we wish regardless of the consequences. The result of this view is a belief in the interconnectedness of all life, thus all life has rights. This work argues that the "dominant" worldview shaped the policies of the U.S. Forest Service (USFS). Consistent with this worldview, the USFS management. paradigm was to provide the greatest return, a commodity-driven focus. However, when public values changed towards a more ecocentric view, the USFS should have reevaluated its method of doing business. Instead, it remained entrenched in its management objective- timber production. After the courts enjoined the USFS against cutting in the Pacific Northwest, aftet struggling with confrontational environmentalists and increased activism within the agency, the USFS attempted to re-write its management paradigm. However even though the policy sounds eco-friendly, the USFS is still mandated by Congress, and forced by appropriations approved by Congress, to cut trees. Different ideologies are accommodated only when they do not conflict with economics. Thus, in spite of changing values, it is still business as usual.

Texte intégral
Résumé :
This study analyzed the top 3 successful snatch attempts by individual lifters in each weight class at a U.S. National Championship weightlifting meet. Two-dimensional (2-D) body position and characteristics of the lifts were compared via 2D video analysis in groups of lifters who displaced forward, showed no displacement, or displaced backward to receive the bar. No significant group differences (p > 0.05) were noted for body mass, bar mass, or hip angle. The rearward displacement group had a significantly greater horizontal distance between the shoulder and heel at the end of the pull (determined as the point where the bar ceases to accelerate vertically). Hip angles for the no displacement group had a small-to-moderate effect size (0.50) in comparison to the forward displacement group, but they only showed a small effect size (0.17) when compared with the rearward displacement group. The forward displacement group showed a small-to-moderate effect size compared with both the no displacement group (0.51) and the rearward displacement group (0.55) concerning the horizontal distance from the shoulder to the heel. These data seem to suggest that rearward displacement in the drop-under phase in the snatch is not detrimental to performance and actually seems to be a preferred technique in U.S. national level lifters. In addition to evidence that rearward displacement is exhibited in elite lifters and is coached globally, it seems this is the preferred technique in international competitions. This technique may be considered a viable variation of the snatch by coaches and athletes of all levels.

Résumé :
Tourism can provide transformational experiences, in positive and/or negative ways, for any tourist. It can provide new experiences that can be (deeply) affective as tourists encounter new places, people, cultures, and activities that they may have never encountered before. For tourists with disability, transformational experiences can be even more significant, again in positive and/or negative ways. An estimated 1.3 billion people (16% of the global population) live with disability (World Health Organisation, 2023). The United Nations (2006) Convention on the Rights of Persons with Disabilities (UNCRPD) asserts that people with disabilities should be able to access, participate in, and enjoy leisure, recreation, and tourism experiences as a fundamental human right. It is important to appreciate that disability is not a homogenous concept, but complex and multifaceted (Buhalis and Michopoulou, 2011; Darcy and Dickson, 2009). Adapting to meet the access requirements of visitors with disabilities is not only beneficial for economic sustainability, but also for the social sustainability of a community, at national, regional/state, and local levels, by putting into practice the values enshrined in the UNCRPD (United Nations [UN], 2006; CockburnWootton and McIntosh, 2020). We note the difference between ‘accessibility’ (often perceived as physical access/infrastructure) and ‘inclusion’ (an understanding and appreciation of diverse customers). In this presentation, we will set out four pillars that are essential in developing tourism destinations to provide accessible and inclusive experiences.

Résumé :
Nutrient enrichment of aquatic environments is a prevalent issue with wide-reaching negative implications for ecological stability, tourism and recreation, and vital drinking supplies. Proper management of nutrient influxes—primarily nitrogen and phosphorus—into aquatic environments is facilitated by continuous monitoring of nutrient levels within water bodies of interest, which offers a more complete understanding of seasonal trends and faster response times compared to traditional lab testing. However, continuous nutrient monitoring systems are prohibitively expensive, with ongoing energy and maintenance requirements that limit deployment. Machine learning shows potential for virtual sensor development with real-time nutrient prediction, based on continuously monitored surrogate indicators. In this study, we test the feasibility of this premise by evaluating the performance of Random Forest regressor (RF), k-Nearest Neighbors (kNN), Support Vector Machine regression (SVM), Decision Tree regressor, Artificial Neural Network, Gradient Boosting Regressor (GBR), and Histogram Gradient Boosting Regressor (HGBR) on one year of water quality testing data from sites across the Continental United States (CONUS). To address values missing not at random, an issue prevalent in water quality testing data, important surrogate indicators are identified by permutation importance. Models are then trained and tuned with Bayesian Optimization to identify hyperparameters optimal for explaining target variance. Across both phosphorus and nitrogen prediction, RF achieved the highest validation performance, with GBR and HGBR trailing marginally. Ensemble tree models appear to be well-suited to continuous nutrient monitoring and may be a cost-efficient solution to greatly supplement the existing highfrequency testing network.

Résumé :
From the late nineteenth century, ramblers, trampers and bushwalkers have been instrumental in the creation of national parks. Their advocacy combined interests in nature conservation with recreational pursuits, heralding the two competing and often contradictory purposes of national park estates. In Australia, protected wilderness areas were invariably repositories of sacred sites linked by networks of walking pads across landscapes shaped by millennia of Indigenous occupation. From the mid-twentieth century, new infrastructure was required in national parks to cater for the growth in tourism. In Australia, the state-based system of “national” parks resulted in an uneven approach to both the creation of protected areas and the design of infrastructure for the hosts and guests. This approach was in marked contrast to the United States, where the Mission 66 program – approved by Congress in 1955 – resulted in a decade-long programme of expenditure on infrastructure that established the reputation of their national park system, and ensured a systematic national approach. This paper examines the piecemeal history of planning for bushwalkers in Australian national parks through a comparison of competing interests – the minimal needs of the self-sufficient rambler with infrastructure that caters for diverse tourism experiences. Australian case studies illustrate a contested but changing approach to planning for pedestrians in protected areas, from the making of tracks by volunteers and depression-era work gangs to elevated walks through forest canopies. A historical analysis highlights the changing attitudes to tourism and conservation challenges, now informed by greater knowledge of ecology and the belated recognition of Indigenous ownership and pre-colonial land management regimes. Threats to the biodiversity in protected areas suggest that a planning approach, which combines multiple disciplines and interests, will increasingly elevate both the bushwalker and tourist in their experience of nature.

Résumé :
Glen Canyon National Recreation Area (GLCA) encompasses more than 0.5 million ha (1.25 million ac) and extends over 322 km (200 mi) from its northern boundary in southern Utah to its southern boundary in northern Arizona. It is one of the most rugged, remote, and floristically diverse national parks on the Southern Colorado Plateau (Thomas et. al 2005) and has more than 4,900 km (3,045 mi) of waterways flowing through its eight Hydrologic Unit Code (HUC 8) watersheds. GLCA’s larger perennial rivers include the Colorado, Escalante, Dirty Devil, San Juan, and Paria, with smaller perennial and intermittent streams flowing into each of these rivers. After the creation of the Glen Canyon Dam, Lake Powell formed, covering 13% of the park’s total land area when full and the national recreation area attracts over 4 million visitors annually, and in 2019 GLCA ranked 19th highest in recreational visits out of all national parks. The National Park Service Natural Resource Condition Assessment Program selected GLCA to pilot its new NRCA project series. NRCA projects evaluate the best available science to provide park managers with reliable, actionable information pertaining to natural resource conditions in their park. For the park-selected focal study resources, this includes consideration of drivers and stressors known or suspected of influencing resource conditions; assessment of current conditions and trends for indicators of condition; and potential near-term and future activities or actions managers can consider, improving their knowledge and management of natural resources in parks. For focal resources that lack adequate data to assess current conditions, a gap analysis is provided (in lieu of a condition assessment) to highlight the present status of knowledge of the resource and to suggest useful indicators, data, and studies for further consideration and investigation. Park managers are encouraged to identify information needs and pose questions during the NRCA scoping process, with the understanding that information will be provided to help address those needs and answer those questions when possible. For a comprehensive list of GLCA managers’ questions and needs, please refer to Appendix A, Table A-1. The focus of GLCA’s NRCA study was the water-dependent resources—tinajas, springs & seeps, including water quality, riparian zone, amphibians, including the northern leopard frog (Lithobates pipiens), and small, native fishes—that are found off the mainstem Colorado River. Managers were interested in these particular environments and the natural resources that depend on them because they are less studied, and the habitats are “biodiversity hotspots” due to the intersection of complex desert and freshwater ecosystems in a region limited by water. The following summaries highlight the key findings of GLCA’s focal resource drivers and stressors (Chapter 2), states (Chapter 3), and manager responses (Chapter 4).

Résumé :
In 2021, recreation visits to National Park Service (NPS) sites rebounded from the COVID-19 pandemic-driven low visitation of 2020 and climbed to 297,115,406 recreation visits. This is an increase of 60 million recreation visits (+25.3%) from 2020 and a decrease of 30 million recreation visits (-9.3%) from 2019. Recreation visitor hours were 1,356,657,749 – a 28.6% increase from 2020 and a 5.1% decrease from 2019. Total overnight stays followed a similar pattern with 12,745,455 overnight stays – up 4.7 million (+58.5%) from 2020 and down 1.1 million (-8%) from 2019. Five parks were added to the reporting system in 2021: Alagnak Wild River in Alaska, Camp Nelson National Monument in Kentucky, Medgar and Myrlie Evers Home National Monument in Mississippi, Tule Springs Fossil Beds National Monument in Nevada, and World War I Memorial in Washington, D.C. These parks were responsible for over 629,000 recreation visits in 2021. Factors influencing visits to National Park System units in 2021 include: continuing closures and limited capacities due to COVID-19 mitigation at some parks, temporary closures for wildland fires in 2021 (eleven parks), severe regional smoke/haze from ongoing wildland fires throughout the summer and early autumn affecting parks in the western half and northern tier of states in the continental U.S., two hurricanes in 2021 – both in August – impacted visitation: Hurricane Henri caused temporary closures of some parks in the northeast and Hurricane Ida caused temporary closures of parks along the Gulf Coast and generated some heavy flooding in the northeast, hurricanes and wildland fires in previous years resulting in lingering closures, most notably Hurricanes Irma and Maria in 2017, the Carr and Woolsey Fires in 2018, Hurricane Dorian in 2019, the Caldwell, Cameron Peak, East Troublesome, and Woodward Fires in 2020, and Hurricane Sally in 2020. Forty-four parks set a record for recreation visits in 2021 and 6 parks broke a record they set in 2020. See Appendix A for a list of record parks. The number of reporting units with over 10 million recreation visits was the same as in recent years (3 parks) and 73 parks had over 1 million recreation visits. Twenty-five percent of total recreation visits occurred in the top 8 parks and fifty percent of total visitation occurred in the top 25 parks. Several parks passed annual visitation milestones including Capulin Volcano NM which passed 100,000 annual recreation visits for the first time, Big Bend NP and Devils Tower NM which each passed 500,000 annual recreation visits for the first time, and Zion NP which passed 5 million visits for the first time. Other parks passed milestones for accumulated recreation visits including Hamilton Grange NMEM (1968-2021) and Palo Alto Battlefield NHP (2003-2021) each passing 1 million total recreation visits, Voyageurs NP (1976-2021) passing 10 million total recreation visits, and Hot Springs NP (1904-2021) passing 100 million total recreation visits. Population center designations were updated in 2021 to reflect overlap of park boundaries with statistical areas from the 2020 U.S. Census. Many population center changes reflect increases in local population as indicated by parks changing from rural to outlying or from outlying to suburban. Other changes reflect increasing complexity in population density as parks changed from a single designation, such as rural or suburban, to a mixed designation. See the Definitions section for population center definitions and Table B.1 for previous and updated population center designations by park. In the pages that follow, a series of tables and figures display visitor use data for calendar year 2021. By documenting these visits across the National Park System, the NPS Statistical Abstract offers a historical record of visitor use in parks and provides NPS staff and partners with a useful tool for effective management and planning. In 2021, 394 of 423 NPS units...

Muldavin, Esteban, Yvonne Chauvin, Teri Neville, Hannah Varani, Jacqueline Smith, Paul Neville et Tani Hubbard. A vegetation classi?cation and map : Guadalupe Mountains National Park. National Park Service, 2024. http://dx.doi.org/10.36967/2302855.

Texte intégral
Résumé :
A vegetation classi?cation and map for Guadalupe Mountains National Park (NP) is presented as part of the National Park Service Inventory & Monitoring - Vegetation Inventory Program to classify, describe, and map vegetation communities in more than 280 national park units across the United States. Guadalupe Mountains NP lies in far west Texas and contains the highest point in the state, Guadalupe Peak (8,751 ft; 2,667 m). The mountain escarpments descend some 5,000 ft (1,500 m) to the desert basins below forming a complex geologic landscape that supports vegetation communities ranging from montane coniferous forests down to desert grasslands and scrub. Following the US National Vegetation Classi?cation (USNVC) standard, we identi?ed 129 plant associations hierarchically tiered under 29 groups and 17 macrogroups, making it one of the most ecologically diverse National Park Service units in the southwestern United States. An aspect that adds to this diversity is that the park supports communities that extend southward from the Rocky Mountains (?ve macrogroups) and Great Plains (one macrogroup) and northward from the Chihuahuan Desert (two macrogroups) and Sierra Madre Orientale of Mexico (three macrogroups). The remaining six macrogroups are found in the Great Basin (one macrogroup), and throughout the southwestern United States (remaining ?ve macrogroups). Embedded in this matrix are gypsum dunelands and riparian zones and wetlands that add further complexity. We describe in detail this vegetation classi?cation, which is based on 540 vegetation plots collected between 2006 and 2010. Full descriptions and diagnostic keys to the plant associations along with an overall plant species list are provided as appendices. Based on the vegetation classi?cation and associated plot data, the vegetation map was developed using a combined strategy of automated digital object-oriented image classi?cation and direct-analog image interpretation of four-band National Agricultural Imagery Program (NAIP) aerial photography from 2004 and 2008 and Landsat Thematic Mapper satellite imagery. The map is designed to facilitate ecologically-based natural resource management at a 1:24,000 scale with 0.5-ha minimum map unit size. The map legend is hierarchically structured: the upper Level 1 consists of 16 map units corresponding in most cases to the USNVC group level, and an additional map unit describing built-up land and agriculture; Level 2 is composed of 48 nested map units re?ecting various combinations of plant associations. A ?eld-based accuracy assessment using 341 vegetation plots revealed a Level 1 overall accuracy of 79% with 90% CI of 74?84% and 68% with 90% CI of 59?76% at Level 2. An annotated legend with summary descriptions of the units, distribution maps, aerial photo examples of map unit polygons, and representative photos are provided in Appendix D. Large wall-size poster maps at 1:35,000 scale were also produced following NPS cartographic standards. The report, plot data, and spatial layers are available at National Park Service Vegetation Mapping Program https://www.nps.gov/im/vegetation-inventory.htm). Outcomes from this project provide the most detailed vegetation classi?cation and highest resolution mapping for Guadalupe Mountains NP to date to support many uses including ?re, recreation, vegetation, and wildlife management, among others. The upper Level 1 map is particularly suited to landscape-scale, park-wide planning and linkages to its sister park, Carlsbad Caverns NP. The Level 2 mapping provides added detail for use at a more localized project scale. The overall accuracy of the maps was good, but because Guadalupe Mountains NP is primarily wilderness park, there were logistical challenges to map development and testing in remote areas that should be considered in planning management actions. In this context, some map units would bene?t from further development and accuracy assessment. In particular, a higher resolution mapping of McKittrick Creek riparian habitat at 1:6,000 scale or ?ner is recommended for this important habitat in the park. In addition, developing a structural canopy height model from LiDAR imagery would be useful to more accurately quantify woody canopy density and height to support ?re management and other habitat management issues. With respect to understanding vegetation dynamics in this time of rapid environmental change, the 540 vegetation plots themselves are su?ciently georeferenced and have the data resolution to be useful in detecting change at the decadal scales across much of the park. To this end, an additional recommendation would be to install more plots to ?ll the gaps among the main vegetation units of the park, both spatially and thematically. Overall, the Vegetation and Classi?cation Map for Guadalupe Mountains NP will support the park?s management e?orts and enhance regional understanding of vegetation and ecology of ecosystems of the southwestern United States.

Résumé :
Abundant gull populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to an acceptable level. Gulls are classified as a migratory bird species and are protected by federal and, in most cases, state laws. In the United States, gulls may be taken only with a permit issued by the U.S. Fish and Wildlife Service. Occasionally, an additional permit is required from the state wildlife management agency.

Texte intégral
Résumé :
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.

Résumé :
Harmful and toxic algal blooms (HABs) are a well-established and severe threat to human health, economies, and marine and freshwater ecosystems on all coasts of the United States and its inland waters. HABs can comprise microalgae, cyanobacteria, and macroalgae (seaweeds). Their impacts, intensity, and geographic range have increased over past decades due to both human-induced and natural changes. In this report, HABs refers to both marine algal and freshwater cyanobacterial events. This Harmful Algal Research and Response: A National Environmental Science Strategy (HARRNESS) 2024-2034 plan builds on major accomplishments from past efforts, provides a state of the science update since the previous decadal HARRNESS plan (2005-2015), identifies key information gaps, and presents forward-thinking solutions. Major achievements on many fronts since the last HARRNESS are detailed in this report. They include improved understanding of bloom dynamics of large-scale regional HABs such as those of Pseudo-nitzschia on the west coast, Alexandrium on the east coast, Karenia brevis on the west Florida shelf, and Microcystis in Lake Erie, and advances in HAB sensor technology, allowing deployment on fixed and mobile platforms for long-term, continuous, remote HAB cell and toxin observations. New HABs and impacts have emerged. Freshwater HABs now occur in many inland waterways and their public health impacts through drinking and recreational water contamination have been characterized and new monitoring efforts have been initiated. Freshwater HAB toxins are finding their way into marine environments and contaminating seafood with unknown consequences. Blooms of Dinophysis spp., which can cause diarrhetic shellfish poisoning, have appeared around the US coast, but the causes are not understood. Similarly, blooms of fish- and shellfish-killing HABs are occurring in many regions and are especially threatening to aquaculture. The science, management, and decision-making necessary to manage the threat of HABs continue to involve a multidisciplinary group of scientists, managers, and agencies at various levels. The initial HARRNESS framework and the resulting National HAB Committee (NHC) have proven effective means to coordinate the academic, management, and stakeholder communities interested in national HAB issues and provide these entities with a collective voice, in part through this updated HARRNESS report. Congress and the Executive Branch have supported most of the advances achieved under HARRNESS (2005-2015) and continue to make HABs a priority. Congress has reauthorized the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) multiple times and continues to authorize the National Oceanic and Atmospheric Administration (NOAA) to fund and conduct HAB research and response, has given new roles to the US Environmental Protection Agency (EPA), and required an Interagency Working Group on HABHRCA (IWG HABHRCA). These efforts have been instrumental in coordinating HAB responses by federal and state agencies. Initial appropriations for NOAA HAB research and response decreased after 2005, but have increased substantially in the last few years, leading to many advances in HAB management in marine coastal and Great Lakes regions. With no specific funding for HABs, the US EPA has provided funding to states through existing laws, such as the Clean Water Act, Safe Drinking Water Act, and to members of the Great Lakes Interagency Task Force through the Great Lakes Restoration Initiative, to assist states and tribes in addressing issues related to HAB toxins and hypoxia. The US EPA has also worked towards fulfilling its mandate by providing tools and resources to states, territories, and local governments to help manage HABs and cyanotoxins, to effectively communicate the risks of cyanotoxins and to assist public water systems and water managers to manage HABs. These tools and resources include documents to assist with adopting recommended recreational criteria and/or swimming advisories, recommendations for public water systems to choose to apply health advisories for cyanotoxins, risk communication templates, videos and toolkits, monitoring guidance, and drinking water treatment optimization documents. Beginning in 2018, Congress has directed the U.S. Army Corps of Engineers (USACE) to develop a HAB research initiative to deliver scalable HAB prevention, detection, and management technologies intended to reduce the frequency and severity of HAB impacts to our Nation’s freshwater resources. Since the initial HARRNESS report, other federal agencies have become increasingly engaged in addressing HABs, a trend likely to continue given the evolution of regulations(e.g., US EPA drinking water health advisories and recreational water quality criteria for two cyanotoxins), and new understanding of risks associated with freshwater HABs. The NSF/NIEHS Oceans and Human Health Program has contributed substantially to our understanding of HABs. The US Geological Survey, Centers for Disease Control and Prevention, and the National Aeronautics Space Administration also contribute to HAB-related activities. In the preparation of this report, input was sought early on from a wide range of stakeholders, including participants from academia, industry, and government. The aim of this interdisciplinary effort is to provide summary information that will guide future research and management of HABs and inform policy development at the agency and congressional levels. As a result of this information gathering effort, four major HAB focus/programmatic areas were identified: 1) Observing systems, modeling, and forecasting; 2) Detection and ecological impacts, including genetics and bloom ecology; 3) HAB management including prevention, control, and mitigation, and 4) Human dimensions, including public health, socio-economics, outreach, and education. Focus groups were tasked with addressing a) our current understanding based on advances since HARRNESS 2005-2015, b) identification of critical information gaps and opportunities, and c) proposed recommendations for the future. The vision statement for HARRNESS 2024-2034 has been updated, as follows: “Over the next decade, in the context of global climate change projections, HARRNESS will define the magnitude, scope, and diversity of the HAB problem in US marine, brackish and freshwaters; strengthen coordination among agencies, stakeholders, and partners; advance the development of effective research and management solutions; and build resilience to address the broad range of US HAB problems impacting vulnerable communities and ecosystems.” This will guide federal, state, local and tribal agencies and nations, researchers, industry, and other organizations over the next decade to collectively work to address HAB problems in the United States.
