Recent studies have suggested that bait movement and caching by foxes (Vulpes vulpes) may increase the potential risk of off-target effects from 1080 meat baits close to urban habitats. The M-44 ejector is an alternative way to deliver 1080 to foxes that will eliminate bait movement and caching. Whilst the M-44 ejector has been used for the control of foxes using cyanide in the United States, we investigated its use with 1080 as a toxicant. Exotic eutherian carnivores are generally more sensitive to 1080 than are most Australian endemic wildlife species, yet no useful difference in sensitivity to cyanide exists for these groups. The lower risk associated with occupational exposure to 1080 compared with cyanide suggests that it is a more desirable toxicant for fox control. Pen trials were undertaken in order to establish an appropriate capsule dose of 1080 to be used in the ejector. A minimum capsule dose of 2.7 mg of 1080 is estimated to be consistently lethal to foxes weighing up to 8.3 kg. The recommended dose is below the current meat bait dose of 3.0 mg 1080 used in Victoria. This may represent an improvement in occupational safety and a reduction in non-target risk.

This paper explores the management implications of a recent study that was designed to explore public and stakeholder values of wildlife in Victoria, Australia. Questionnaires (n = 1431) were used to examine values and knowledge of wildlife held by residents from seven Victorian municipalities and members of six wildlife management stakeholder groups. The results suggest that most Victorians have a relatively strong emotional attachment to individual animals (the humanistic value) and are interested in learning about wildlife and the natural environment (the curiosity/learning/interacting value). In comparison, the negativistic, aesthetic, utilitarian-habitat and dominionistic/wildlife-consumption values were not expressed as strongly. These findings suggest that wildlife managers should expect support for wildlife management objectives that reflect the relatively strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife.

Koala populations in Australia are declining due to threats such as chlamydiosis, wild dog predation and vehicle collision. In the last decade, grazing livestock emerged anecdotally as a threat to koala survival in areas where koala habitat and livestock grazing land overlap. This is the first study investigating the significance of livestock-inflicted injuries and deaths in koala populations over a large spatial and temporal scale. We investigated the outcome, scale, and frequency of livestock–koala incidents via an online survey and analysed koala admission records in Queensland wildlife hospitals and a wildlife rescue group (Wildlife Victoria) in Victoria. The results provide evidence of both livestock-inflicted injuries and deaths to koalas, especially as these have been confirmed by witness statements. The outcomes for the koala victims of the incidents were severe with a 75% mortality rate. The reported frequency of livestock–koala incidents was low but increasing, with 72 cases (0.14% out of 50,873 admissions) in Queensland wildlife hospitals during 1997–2019, and 59 cases (0.8% of 7017 rescue records) in Wildlife Victoria during 2007–2019. These incidents were likely to be under-reported due to the remoteness of the incident location, possible mis-diagnoses by veterinarians and the possible reluctance of farmers to report them. Future research is encouraged to explore the mechanics and causes of livestock–koala incidents and to develop management strategies to minimise the livestock threat to koalas.

Abstract Over the last four decades, forest management goals have transitioned to multiuse objectives, begging the question of their impact on wildlife habitat. Using USDA Forest Service Forest Inventory and Analysis data and the WHINGS (Wildlife Habitat Indicator for Native Genera and Species) model, the trends in wildlife habitat were quantified from 1977 to 2018 across Minnesota. Statewide, 35.5% of species experienced significant improvement in habitat, 29% significant reductions, and 35.5% nonsignificant change. The extent of habitat (acreage) increased for 100% of species, but the quality declined for 63% of species. Results were explained by the reduction in acreage of larger size classes of the aspen, balsam, and birch forest type and increases in smaller, younger forest area. Specifically, forest management that converted aspen stands to other forest types benefited certain wildlife species over others. Future forest management should consider the balance between the habitat requirements of the diverse native species in Minnesota. Study Implications Trends in forest wildlife habitat over the last four decades across Minnesota highlight that forest management often favors one species at the expense of another. Statewide, wildlife species with preferences for larger, older aspen experienced diminished habitat, whereas habitat for species preferring younger forest types or older nonaspen types increased. Regionally, the forested ecoregions in Minnesota (northeast) generally saw reduced habitat, whereas the prairie/agricultural regions (south and northwest) saw the largest increases. Through this and further applications, forest and wildlife managers can rapidly assess the habitat implications of proposed management, whether for environmental review, forest planning, or harvest scheduling.

AbstractWildlife and fish have much to gain from the movement toward alternative, sustainable agricultural practices. Interrelated reasons for the habitat improvements to be expected from a change to sustainable systems include reduced use of agricultural chemicals, better care of the soil, and reintroduction of greater landscape diversity. The most well-documented benefits would result from reduced use of agrichemicals, which often are toxic and frequently change the structure and composition of available food and cover. The wildlife benefits of erosion prevention and landscape diversification are less well-documented but may be as significant for habitat improvement. The opportunities to enhance habitat using sustainable farming methods are beginning to receive increased attention from wildlife professionals. As a result, efforts are under way to expand use of sustainable methods on farmlands managed by the U.S. Fish and Wildlife Service.

Water quality improvement is generally the primary objective of treatment wetlands. Creation of wildlife habitat is an inevitable outcome of these projects. However, an increasing number of treatment wetland projects have been purposely designed and operated to enhance their beneficial utility to wildlife and humans. This trend to multi-purpose treatment wetlands has broadened the basis for assessing the advantages of this natural treatment alternative. There are at least 21 treatment wetlands in the U.S. that were implemented with wildlife habitat creation and/or human use as principal goals. A number of treatment wetlands outside the U.S. also share these priorities. Hundreds of other wetlands have collected and reported quantitative data on wildlife and/or human uses. The North American Treatment Wetland Database (NADB) has been expanded to include critical wildlife habitat and human use data. This paper provides a preliminary inventory of these habitat and human use treatment wetlands, summarizes lessons learned, and identifies additional data needs.

Abstract The Northeastern Forest Inventory and Analysis unit has completed one full cycle of forestland ownership surveys. The results of 14 state surveys show the majority of forestland of the region to be controlled by a large, diverse population of nonindustrial private landowners. These people are from varied background and exhibit a wide range of interests and attitudes toward wildlife, wildlife habitat, and forest management. The demographic and additional characteristics of forest landowners, together with the structural characteristics of their forestland, creates opportunities for, and constraints upon, forest management favorable for wildlife habitat improvement.

The southern brown bandicoot (Isoodon obesulus) occurs across the periphery of southern and eastern Australia as a series of isolated regional populations. Historical records and recent surveys conducted for I. obesulus indicate that it has disappeared or decreased significantly from many parts of its former range. Vegetation clearance, habitat fragmentation, feral predators and fire have all been implicated in the decline of the species. This paper examines the distribution of I. obesulus in the Portland region of south-western Victoria. Historical records of I. obesulus were compiled from the specimen collection of Museum Victoria, the Atlas of Victorian Wildlife, Portland Field Naturalists’ Club records and anecdotal sources. Field surveys were conducted to determine the current distribution of I. obesulus in the study area based on evidence of its foraging activity. The historical records reveal limited information: most are clustered around centres of human activity, indicating observational bias. The field surveys demonstrate that I. obesulus occurs in the Portland region as a series of local populations. Each local population is associated with a patch of remnant native vegetation separated from neighbouring patches by dispersal barriers. Within these habitat remnants the occurrence of the species is sporadic. Approximately 69% of the potential habitat is managed by the Forests Service, 31% is managed by Parks Victoria, and less than 0.5% is held under other tenures. Spatial isolation of habitat remnants, fires and feral predators are the main threats to I. obesulus in the Portland region.

We review the distribution, habitat and conservation status of the eastern pygmy-possum (Cercartetus nanus) in Victoria. Data on the habitat occurrences and rates of detection were gleaned from 133 published and unpublished fauna surveys conducted from 1968 to 2003 in Gippsland; northern Victoria; the Melbourne area and south-western region. C. nanus was reported from a broad range of vegetation communities, which predominantly included a dense mid-storey of shrubs rich in nectar-producing species such as those from the families Proteaceae and Myrtaceae. Survey effort using a range of methods was immense across surveys: 305,676 Elliott/cage trap-nights, 49,582 pitfall trap-nights, 18,331 predator remains analysed, 4424 spotlight hours, and 7346 hair-sampling devices deployed, 1005 trees stagwatched, and 5878 checks of installed nest-boxes. The surveys produced 434 records of C. nanus, with Elliott/cage trapping, pitfall trapping and analysis of predator remains responsible for the vast majority of records (93%). These data and those from the Atlas of Victorian Wildlife indicate that although C. nanus has a widespread distribution in Victoria, it is rarely observed or trapped in fauna surveys. Only 11 (8%) of the surveys we reviewed detected >10 individuals. C. nanus is likely to be sensitive to several recognised threatening processes in Victoria (e.g., feral predators, high frequency fire, feral honeybees). There is also evidence of range declines in several regions, which suggests that the species is vulnerable to extinction. Therefore, we recommend that it be nominated as a threatened species in Victoria.

The Harris County Flood Control District is implementing a wetland mitigation bank project that includes highway runoff as a significant water source. Part of this project is being implemented in cooperation with the Texas Department of Transportation through funding from the Intermodal Surface Transportation Efficiency Act for water quality improvement. This collaborative effort includes treatment and final polishing of storm water runoff from a portion of Beltway 8, northeast of Houston, Texas. The project includes approximately 89 ha (220 acres) of storm water-polishing wetlands and associated wildlife habitat. The overall train of natural treatment processes includes a tie-in to the existing beltway storm sewer, a surge basin for initial collection and storage of storm water, a pump station and force mail allowing flexible water delivery to the rest of the system, a series of polishing ponds and polishing wetland marshes, and an interconnected array of habitat wetlands and swales including ponds, littoral marshes, and transitional wetland forest areas. Design of the polishing and treatment wetlands balances the multiple goals of water quality improvement, flood-flow retention, and creation of valuable wildlife habitat.

A study was undertaken to explore relationships between wetland characteristics which make them efficient water purifiers versus their ability to serve as wildlife habitat. The effects of designing constructed wetlands for improved habitat on water treatment efficiencies were quantified. Results indicate that some sacrifice in treatment efficiency is required and that the degree of efficiency reduction is dependant upon pollutant loading rates. However, sacrifice in efficiency is much smaller than increase in habitat quality, and can be offset by increasing wetland area. A practical, theoretical application was then attempted.

The purpose of this study was to evaluate the potential for protecting critical resplendent quetzal habitat on private lands bordering the south-western edge of the Monteverde Cloud Forest Reserve, Costa Rica. First, a habitat analysis was made of 12 forest patches using a 10% strip method to obtain an importance value for the Lauraceae fed on by the resplendent quetzal. Second, a landowner survey was conducted using a structured interview questionnaire to determine landowner attitudes, and the possible factors influencing these attitudes, towards forested land, wildlife, the resplendent quetzal and potential habitat protection incentives. Significant differences were found between forest patch importance values for the Lauraceae suggesting that for conservation purposes careful forest patch selection is important. Most landowners were found to value their forested land more than their land under other uses and to favor technical forest management assistance over leasing. If funding can be made available there is a good chance that resplendent quetzal habitat can be adequately protected and managed through providing assistance to those landowners with the most critical forest patches.Department of Natural Resources

Increased afforestation and protective legislation in the latter half of the 20th Century allowed the British pine marten Martes martes population to recover from near extinction. Although still largely confined to northern Scotland, the marten population is expanding its size and range by utlising coniferous plantation forests which have become increasingly available. However, little is known about the marten’s ecology in plantation forestry, and less about how they may adapt to changing silvicultural trends. This study investigated aspects of pine marten ecology within Morangie forest, a managed plantation in NE Scotland, with the ultimate aim of formulating management guidelines for modern plantation forests. During the course of the study 11 pine marten were radiotracked and their home ranges mapped to examine marten-habitat associations at several spatial scales. Compositional analysis of habitat based on dominant vegetation type showed that martens established their home ranges in areas dominated by mature forest, whilst showing relative avoidance for open heath moor and grazed pasture. Within home ranges, foraging martens utilised patches of graminoid vegetation, such as those typically associated with Microtus voles, in areas with little or no tree canopy cover. These findings provide unequivocal evidence that fine-scale patches of non-forested habitat provide crucial foraging resources for marten, and therefore ought to be provisioned for in forest management plans. To assist the implementation of these requirements in forest planning, a model was developed to predict the fine scale distribution of Microtus-rich foraging habitat for marten using GIS-based habitat variables that are routinely available to forest managers: topographic wetness index, stand tree height and stand basal area. Management recommendations of ways to improve wind-firm plantation forests as habitats for pine marten are provided. To augment the investigation of marten spatial ecology, the diet of martens was examined seasonally through the analysis of contents from c. 2450 scats, 86 % of which were genetically identified as being pine marten in origin. Marten diets displayed marked seasonality, but small mammals, berries and small birds were the principal foods consumed based on both frequency of occurrence and estimated weight of biomass ingested. Comparison of the relative composition of small mammal species in the diet with those available in the environment revealed that marten displayed an indisputable preference for Microtus voles. Such habits demonstrate that the niche of Scottish martens has diverged from those in mainland populations which predominantly prey upon Clethrionomys voles. A comparison of the marten’s winter diet with those found in studies at similar latitudes (58°N) demonstrated that the Scottish diet was more similar to diets at more southerly latitudes as they contained more fruit and fewer large mammals than typically boreal diets. Investigation of inter-annual variation of the marten’s spring diet from five successive years revealed that Microtus were consistently the most important prey species in the diet each year. Indirect evidence of the relative abundance of Microtus suggested that Microtus populations were non-cyclic. Findings are discussed with reference to the unique ecological circumstances confronting marten in the Scotland; typical of insular populations the UK has a depauperate native fauna in comparison with mainland Europe, in addition to this, mild climatic conditions, particularly over winter, and a historically fragmented landscape appear to have allowed the niche of the Scottish marten to diverge from that considered typical elsewhere in its range. The Scottish marten is dependent on both forested and open habitats, and is both a Microtus specialist and trophic generalist.

Monitoring the distribution, abundance and demography of species is vital to ensure that conservation efforts are appropriate and effective. Monitoring enables evaluation of responses to natural or human disturbance, highlights the need for management interventions and enables these interventions to be assessed and refined. The methods used largely depend on the specific aim of monitoring and behaviour of the target species, as well as the time and spatial scale that monitoring is required to cover. The European pine marten (Martes martes) is one of few remaining mammalian predators native to the UK. Since persecution in the early 19th century resulted in their near extinction, pine martens have recovered part of their former range in Scotland. Their recent recovery and an overlap in territory with vulnerable prey species such as the capercaillie (Tetrao urogallus) make the collection of accurate baseline data and subsequent monitoring of population trends vital for conservation efforts. Faecal counts have traditionally been used to provide a relative measure of population density for pine marten. In most cases, absolute measures of population density require individual identification. Non-invasive genotyping can provide this information but the quality of DNA from these samples is often poor. Here, the process is refined for pine marten faeces (scats) and hair samples. DNA degradation increased significantly for scats exposed to rainfall, with the rate of DNA amplification success reduced by 38% over a 16 day period. Success rates for hair samples were higher when more hair follicles were included in the analysis. Population densities were estimated for three forests in Scotland using a robust combination of non-invasive genotyping of hair samples and spatially explicit capture recapture modelling. Population density estimates of 0.07 (95% CI 0.03 - 0.16) to 0.38 km-2 (95% CI 0.11 - 1.07) were obtained which are within the range of previous estimates for forests elsewhere in Scotland. The first attempt to quantify the relationship between traditional scat counts and home range size was then conducted; a significant negative correlation exists but only when population density is relatively low. Previous studies suggest that pine martens in Western Europe are less forest dependent than those in Eastern Europe. Results from this thesis support this, with populations at the highest density found at sites with intermediate forest cover. This tolerance of lower forest cover is also apparent in the diet. Despite a preference for Myodes voles in populations in Eastern Europe, those in Western Europe show a strong preference for Microtus voles as well as a higher level of frugivory. We assess the autumn diet of four populations in Scotland assess the effect of forest cover and sex on the diet. There was no evidence of differential consumption of Microtus voles or birds between the sexes. Our analysis shows that frugivory is influenced by forest fragmentation, with a 5-fold increase in the occurrence of fruit (from 2% to 10%) as forest cover increased from 4% to 47%. Diversionary feeding has been suggested as a management technique to reduce the depredation of capercaillie by pine martens. This thesis presents the first attempt to quantify the success and cost-efficacy of diversionary feeding for a range of problems (crop damage, threatened safety, livestock depredation) across 30 experimental trials. The strategy proved more effective when targeted towards food-limited populations, and when aiming to alleviate habitat damage or risks to human safety rather than depredation. A novel decision-making framework was developed to aid managers with the initial planning of the strategy and its subsequent implementation within an adaptive format. Further to this, the feasibility of using diversionary feeding with a view to reduce the depredation of capercaillie by pine martens was assessed. Questionnaire responses were collected from people who have provided food for pine martens throughout Scotland. A positive reaction to food was observed, with 58% of respondents reporting that initial visits occurred within one week of placement and 46% reporting that subsequent visits were received daily. These results suggest that diversionary feeding may be a viable option for pine marten management, although testing of its impact on capercaillie productivity would be required.

Wetlands in the United States have been decreasing in number from the time European settlers began draining them for agricultural purposes to the present. Wetlands serve many important ecological functions such as waterfowl habitat.The purpose of this project was to investigate wetland creation literature in order to develop a process which could be applied to a particular site to attract waterfowl. The topics reviewed for this project were goal setting, for wetland creations, wetland creation methodologies and waterfowl habitat criteria. The major portion of the project was devoted to the construction process of the wetland. The criteria used to direct the wetland construction were hydrology, topographic contour design, revegetation, and protective buffers. Trail development to provide public access for educational purposes was also an important component of the wetland design. Waterfowl habitat criteria was also researched and applied to the project in order it insure that waterfowl would be attracted to the wetland.The process developed from the research was applied to Jim Haberek's property located in Anderson, Indiana. The product was a masterplan which included a site analysis, a water level management plan, a contour design, a revegetation plan, protective buffers and a trail design for the public.Department of Landscape Architecture

ZusammenfassungRothirsche, in der Jägersprache als Rotwild bezeichnet, können starke Emotionen hervorrufen und große Konflikte verursachen. Das Management von Rotwild sollte evidenzbasiert sein, sich also an wissenschaftlich gewonnenen Erkenntnissen orientieren. In diesem Kapitel fasse ich zusammen, wie solch ein evidenzbasiertes Rotwildmanagement grundsätzlich gestaltet sein sollte und welche Evidenzen es für verschiedene Aspekte des Rotwildmanagements gibt. Hierbei spielt die Jagd zwar eine wichtige Rolle, ist aber nur eine der möglichen Maßnahmen, mit denen Managementziele erreicht werden können. Ebenso ist die numerische Steuerung von Populationsgrößen bzw. -dichten in der Regel nur ein Zwischenziel im Management.Ein evidenzbasiertes Rotwildmanagement sollte adaptiv aufgebaut sein und somit immer eine Erfolgskontrolle beinhalten, durch die sowohl die Umsetzung als auch die Wirkung von Managementmaßnahmen stetig überprüft und verbessert werden können. Solch eine Erfolgskontrolle basiert auf einem Langzeit-Monitoring, das mindestens die Faktoren Populationsentwicklung, Wildzustand und Wildeinfluss beinhalten sollte.Die Verbreitung von Rotwild sowie der Austausch zwischen einzelnen Vorkommen werden in Deutschland stark von gesetzlichen Vorgaben und der Landschaftszerschneidung durch Siedlungen und Straßen bestimmt. Durch die räumliche Isolation und den damit einhergehenden geringen Genfluss zeigen einige Rotwildvorkommen bereits stark reduzierte genetische Diversität, sehr kleine genetisch-effektive Populationsgrößen und hohe Inzuchtwerte. Vor diesem Hintergrund sollte die Vernetzung der Rotwildvorkommen verbessert werden, was einerseits durch die Abschaffung rotwildfreier Gebiete erreicht werden könnte, andererseits durch Wiedervernetzungsmaßnahmen, z. B. durch Wildkorridore und Querungshilfen über Verkehrsinfrastrukturen.Rothirsche passen ihr Raum-Zeit-Verhalten und ihre Habitatwahl an eine „Landschaft der Angst“ an, die vom wahrgenommenen Mortalitätsrisiko, dem Nahrungsangebot und der Habitatstruktur abhängt. Auch Störungen durch menschliche Aktivitäten spielen hierbei eine wichtige Rolle. Wissenschaftliche Studien belegen, dass sich Rotwild durch eine Steuerung dieser Faktoren in Raum und Zeit lenken lässt, wodurch Konflikte reduziert werden können. In der Praxis kann hierfür eine Zonierung für das Flächenmanagement sowie eine Kombination aus lokaler Schwerpunkt- und großflächiger Intervallbejagung angewandt werden, über die Rotwild von bestimmten Flächen ferngehalten und auf andere Flächen gelenkt werden kann.Einige der bestehenden Abschussvorgaben für Rotwild erscheinen biologisch nicht plausibel, und es ist nicht sicher nachgewiesen, ob sie die gewünschten Effekte haben. Die Abschussplanung bzw. die dafür nötige Zuwachsberechnung erfolgt meist anhand von unbekannten Parametern zu Reproduktionsraten, Populationsstrukturen und Mortalitäten. Die hierdurch entstehenden Unsicherheiten bei der Vorhersage zukünftiger Bestandesentwicklungen sollten durch zusätzliche, populationsspezifische Forschung gemindert werden. Um Rotwildbestände über die Jagd zu reduzieren, müssen vor allem Alttiere erlegt werden, was aus Gründen des Tierschutzes den vorherigen Abschuss der geführten Kälber erfordert.Basierend auf diesen Evidenzen mache ich grundsätzliche Vorschläge für das Rotwildmanagement, schlage Schritte vor, um weitere Evidenzen zu schaffen, und identifiziere weitergehenden Forschungsbedarf.AbstractRed deer can cause strong emotions and also severe damage. Red deer management should be evidence-based and hence use scientifically derived information. In this chapter, I summarize what an evidence-based red deer management should generally look like and what evidences actually exist for different aspects of red deer management. Hunting plays an important part in this, but is just one possible action to reach management goals. Similarly, the numeric control of population abundances or densities is usually just an intermediate goal in wildlife management.An evidence-based red deer management should be adaptive and hence requires a control of success, so that implementation and effect of management actions can constantly be evaluated and improved. Such a control of success is based on a long-term monitoring that considers at least the three factors population development, animal performance, and herbivore impacts.The distribution of red deer in Germany and the exchange among populations are severely impacted by legal regulations and by landscape fragmentation due to settlements and roads. The spatial isolation and associated low levels of gene flow have already led to low genetic diversity, low genetic-effective population sizes and high inbreeding values in some populations. This calls for an improvement of connectivity among red deer populations, which could be accomplished by giving up areas where red deer are not allowed to exist, and by defragmentation measures, such as wildlife corridors and crossing structures over transportation infrastructures.Red deer adjust their space-time-behavior and habitat selection to the landscape of fear, which is shaped by the perceived mortality risk, food availability and habitat structure. Disturbances by humans also play a major role in this. Scientific research shows that red deer can be steered in space and time through these factors and that such a steering can reduce conflicts. From a practical standpoint, such steering can be accomplished by a zoning concept that combines area management, locally intensive hunting and broad-scale hunting in intervals, so that red deer are kept away from certain areas while being steered into other areas.Some of the existing harvesting guidelines appear biologically implausible and their effectiveness has not sufficiently been demonstrated. Harvest planning is often based on unknown values for reproduction rates, population structures and mortalities. This leads to high uncertainties when predicting the future development of populations, calling for population-specific research to reduce these uncertainties. To reduce red deer abundances, especially adult females need to be harvested. Due to animal welfare laws, this is usually accompanied by an increased harvest of calves.Based on these evidences, I provide general guidelines for red deer management, suggest further steps for generating additional evidences, and identify remaining research needs.

The era of the Information Technology revolution has endeavored mankind with enormous technological comforts. Apart from human health care, cloud computing integrated with other technologies can be exploited for the welfare of endangered wildlife animals that are currently on the verge of facing extinction in the near future. International Union for Conservation of Nature (IUCN) has declared a huge number of wildlife species into red list falling into 'critically endangered', 'endangered' and 'vulnerable' species because of pathogenic diseases, poaching, habitat degradation, and climate change. The aim of the chapter is to propose a cloud computing based wildlife health care model to preserve, sustain and protect the global wildlife heritage and wildlife conservation by identifying and providing treatment to diseased animals, monitoring their health conditions periodically and protecting against poaching. The proposed health care model makes use of various wearable sensors implanted on and within the body of an animal. The sensors perform data gathering about different body-related parameters to be transmitted to a cloud system for analysis and reporting a required timely action. When a cloud system senses emergency with respect to the health-related or threat-related incident, the information is immediately signaled to wildlife physician and wildlife ranger respectively to act accordingly.

<em>Abstract</em>.—Waquoit Bay is a coastal estuary located on the south side of Cape Cod. The primary rivers feeding the bay, the Quashnet and Childs rivers, are small, coldwater, groundwater-fed streams. Most of the watersheds of both rivers were originally set aside in the 1600s as a plantation for the Native American Mashpee Wampanoag tribe. The rivers were heavily modified in the late 1700s by the building of mill dams and later in the 1800s by cranberry agriculture. The anadromous Brook Trout <em>Salvelinus fontinalis </em>fisheries in both rivers were acclaimed in the early 1800s. Anadromous river herring <em>Alosa </em>spp. runs were created on both streams by connecting the streams to Johns Pond, a natural kettle hole pond. After anadromous Brook Trout populations declined due primarily to habitat loss, efforts were initiated in the 1950s to restore anadromy to Brook Trout in Cape Cod rivers by overstocking with hatchery Brook Trout. After this project, land protection along the river started with the purchase of abandoned cranberry bogs. Both rivers were heavily stocked with Brown Trout <em>Salmo trutta </em>in the 1970s and 1980s to create a sea-run Brown Trout fishery. In 1976, Trout Unlimited began an ongoing habitat improvement project in the Quashnet River. In the 1970s and 1980s, the rapid development of Cape Cod threatened the watershed. In 1988, the Waquoit Bay National Estuarine Research Reserve was formed and the Commonwealth of Massachusetts purchased land in the watershed to preserve it as open space. As part of the purchase agreement, a potential well site was reserved, which led to studies by the U.S. Geological Survey on the hydrology of the Quashnet River and the impact of potential wells. In the early 1990s, fisheries management shifted away from the stocking of Brown Trout to focus on the native Brook Trout fishery. The Mashpee National Wildlife Refuge, a consortium of landowners centered on Waquoit Bay, was formed in 1995. In 1997, the contaminant ethylene dibromide from the former Otis Air Force Base Superfund site was found to be entering the upper Quashnet River. This led to the creation of a system of berms and groundwater extraction systems. The failure of part of the berm system led to concerns about fisheries impacts, and a restoration plan was developed. A Brook Trout passive integrated transponder tagging project was initiated on the Quashnet River in 2007, and the Brook Trout population has been annually sampled since 2000. In 2008–2010, adult wild Brook Trout from the Quashnet River were transplanted to the Childs River and a wild Brook Trout population was reestablished. Nitrogen loading from the watershed has become a major issue for the Waquoit Bay estuary, causing algae blooms and water-quality impacts. The fisheries of the Waquoit Bay tributaries have been protected and enhanced by an ongoing combination of land protection, fisheries management and research activities, and habitat improvements involving a wide variety of partners. Watershed development and potential climate change continue to threaten both the estuarine resources of Waquoit Bay and the native freshwater and diadromous fisheries of its tributaries.

Ecosystem management, in the ideal sense, gives appropriate consideration to the complex and interdependent ecological and social systems that comprise forestlands. One prominent and growing arena where ecological and social systems interact is in the recreational use of wildlands. Recreational uses of forestlands are among an extensive array of commodities and amenities that are increasingly demanded of forest managers. An in-depth understanding of the relationships between recreational and other important uses is essential to effective ecosystem management. Within the human dimension of ecosystem management, recreation and amenity uses of forestlands and the associated benefits of those uses, constitute an important component of management decisions. Forestland recreation is a special form of leisure behavior not only because it takes place outdoors, but because it depends upon a “natural” setting. Particular environmental settings are crucial to the fulfillment of forest recreation goals, because the recreationist seeks meaningful and satisfying experiences rather than simply engagement in activities. Importantly, wildland recreation takes place in settings that result from management actions of one form or another, whether the management objective is recreation opportunity, wildlife habitat improvement, or timber production, among others. The recreation opportunity spectrum (ROS) provides a conceptual framework for relating opportunities for particular behaviors and experiences to specific settings. The ROS argues that recreator's pursuits of certain activities in specific settings reveals their demand for experiences that are satisfying and that may give long-term benefits. The ROS framework describes a spectrum of recreation opportunity classes that relate a range of recreation experiences to an array of possible settings and activities. Setting structure is composed of three components: an ecological component, a social component, and a managerial component. The ecological component comprises the physical-biological conditions of the setting. These are typically delineated by the relative remoteness of the setting, its size, and evidence of human impact (number and condition of trails, structures, or roads, alteration of vegetation, etc.). The social component is typically defined by the number of users at one time (density) in the setting, delineated by the number of encounters or sightings a recreation party has with others.

Wetlands in the arid Central Basin and Range (“Central Basin”) ecoregion of Utah are scarce but provide important functions including critical habitat for wildlife including Species of Greatest Conservation Need and migratory birds, water quality improvement, and recreational and aesthetic values. The Utah Geological Survey (UGS) conducted a study in 2019 and 2020 to better understand the location, type, condition, and potential function of wetlands in the ecoregion. This study focused on areas in the Great Salt Lake and Escalante Desert-Sevier Lake (“Sevier Basin”) HUC6 watersheds within the Central Basin to complement previous work by the UGS that focused on other watersheds in the ecoregion.
