Elodea spp. (Elodea) is Alaska’s first known invasive aquatic plant, first discovered in urban lakes in 2010. The combination of human pathways and climate change related shifts in seasonality and temperature have resulted in Elodea’s range expansion into Alaska’s freshwater resources. Elodea transmission often occurs when plant fragments get entangled in seaplane rudders and are carried to remote waterbodies where they quickly establish dense plant growth. This growth inhibits seaplane access and drastically alters aquatic ecosystems. Recent research showed that Elodea can have significant negative impacts on parks, subsistence, aviation‐related recreation, and Alaska’s salmon fisheries. For example, the economic...

Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White Suckers) to create hybridization and reduced reproductive success. Minnows are more diverse in the Adirondacks, and our analyses suggest that they show three major distributional patterns that reflect post-glacial colonization and temperature preferences. We are analyzing data from hundreds of lakes to discern the rules that structure...

The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to generate metrics for pilot ecosystem accounts for the southeast – part of natural capital accounts that assess ecosystems’ contributions to the economy in order to help governments better understand their reliance on natural systems and manage natural resources to ensure their benefits are sustained into the future. These data were...

Invasive annual grasses are a primary, severe, and challenging threat to habitat conservation and restoration for sage-dependent wildlife across federal, state and private lands. Successful management solutions for sagebrush rangelands are likely to be multiphasic, involving some sequence of interventions such as herbicides, seeding of competitive natives that also create habitat, and temporarily altering land use, in an adaptive-management approach. The proposed work tests different herbicides and options for applying them with different seeding and land uses, across a gradient of climate and soils in Interior Regions 5 and 7.This research will examine the efficacy of management options for controlling cheatgrass...

Conifer encroachment is one of the most significant threats to sagebrush habitats and the species that rely on them. Removal of encroaching conifers is beneficial for Greater Sage-Grouse, but impacts on other sagebrush-obligate species are not well understood. This project aims to quantify the impact of conifer removal on sagebrush songbird abundance and reproductive success. Work has been initiated through a previously-supported (by IR5/7 SA) Cooperative Fish and Wildlife Research Unit project across six conifer-removal and six conifer-remaining (control) plots of ca. 55 ha each. Initial results suggest that conifer removal benefits both abundance and nesting success of sagebrush-obligate species (Brewers Sparrows...

The Wind River Reservation in Wyoming contains over 2 million acres of the best and most diverse and intact habitats in the contiguous US. It is home to the Eastern Shoshone and Northern Arapaho Tribes. In collaboration with Tribal Fish and Game, the USFWS Lander Fish and Wildlife Conservation Office and the USGS Wyoming Cooperative Research Unit, partners have been conducting an investigation of the migration patterns of 113 GPS-collared mule deer that began in 2018. As part of our SA diversity and inclusion efforts with a $60,500 investment, this project will extend the ongoing work and engage various segments of the tribal community in the research as a means to further understanding of fish and wildlife management...

To better inform conservation efforts targeted at reversing grassland bird declines and ensure self-sustaining populations of at-risk species such as the lesser prairie-chicken (Tympanuchus pallidicinctus), a better understanding of broad-scale habitat availability for grassland birds is needed. his project will evaluate the utility of NDVI and phenology-based metrics in estimating lesser prairie-chicken reproductive habitat quality remotely over broad spatial scales.1. Evaluate the influence of grazing, fire, and precipitation on NDVI-related metrics in the Central and Southern Great Plains.2. Identify NDVI-related metrics that best distinguish lesser prairie-chicken reproductive habitat from non-habitat. 3. Relate...

The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...

Using a solutions-oriented, multi-agency collaboration, we propose to pilot a large-scale assessment of an alternative (herding, electric- and virtual-fence) grazing strategy designed to mimic pre-colonial grazing patterns by bison, to ascertain their value for local- and regional-scale assemblages ofsagebrush- and grassland-associated birds in Montana. A fundamental goal of most wildlife-based grazing programs is to foster a mosaic of patches that represent the broadest possible spectrum of habitat types that benefits different sagebrush- and grassland-associated birds in different parts of the landscape (for example, western meadowlarks, vesper sparrows, and thick-billed longspur in open, heavily grazed areas;...

Grassland loss to woody encroachment is widespread and ongoing. Mechanical removal of Eastern Red Cedar (ERC) is the most cost-shared practice to address this threat. Cost-share is provided based on acres with different levels of infestation. Delineation of the different levels of infestation is time consuming butrequired to ensure the appropriate amount of cost-share is provided and contractors are not over/under compensated. The Rangeland Brush Estimation Toolbox(RaBET) is geospatial tool that can accurately automate this process. Unfortunately,wet-meadows and other wetland features cause the tool to overestimate woody cover. This project will provide funds to finish the National Wetlands Inventory (NWI). This...
Conservation planning, the process of deciding how to protect, conserve, enhance and(or) minimize loss of natural and cultural resources, is a fundamental process to achieve conservation success in a time of rapid environmental change. Conservation targets, the measurable expressions of desired resource conditions, are an important tool in biological planning to achieve effective outcomes. Conservation targets provide a focus for planning, design, conservation action, and collaborative monitoring of environmental trends to guide landscape-scale conservation to improve the quality and quantity of key ecological and cultural resources. It is essential to have an iterative and inclusive method to define conservation...
Mortalities of Florida manatees (Trichechus manatus latirostris) have significantly increased this winter, especially along the East Coast of Florida, leading to the declaration of an Unusual Mortality Event (UME). Carcasses are exhibiting signs of starvation, related to a lack of food resources from persistent algal blooms and cold stress. These conditions are expected to continue through at least next winter. We will perform health assessments with our partners and attach GPS telemetry tags for current information on habitat use. We will perform habitat surveys at sites used by manatees, determine available species composition and extent, and collect data to inform carrying capacity estimation. Specific objectives...

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

The Anaktuvuk River Fire was the largest, highest-severity wildfire recorded on Alaska’s North Slope since records began in 1956. The 2007 Anaktuvuk River Fire was an order of magnitude larger than the average fire size in the historic record for northern Alaska and indices of severity were substantially higher than for other recorded tundra burns. An interdisciplinary team assessed fire effects including burn severity, potential plant community shifts, and effects on permafrost and active layers. Observers monumented, photographed, and measured 24 burned and 17 unburned reference transects, starting the year after the fire, and spanning the range of vegetation types and burn severities.
