The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

This R code (YKDsalinity_QC.R) is used to process the raw legacy salinity data for fixed and random plots (2006 - 2019) and produce the quality controlled legacy salinity data for analysis and sharing (YKDsalinity_QC.csv). Basic operations include transforming missing value to a common code, transforming other variables to match the data dictionary, and cleaning spatial location issues. Of special note is that this QC process discover significant error in location data due to a variety of reasons so the random plot centers are added to the data table and should be used for analysis. The code requires the raw data (“Official_YKD.SALINITY.DATA.MASTER.2020.csv”), a definition of the nest plot study area (“NestPlotStudyAreaBoundary.geojson”),...

Geodatabase that contains US Fish and Wilflife Service (FWS) One Range, Current Range, Speceis List Area (SLA), and Area of Influence data for speceis listed under the Endangered Speceis Act (ESA), within the state of Wyoming. Summary of each range type below. To ensure latest version of range data and additional information please look up species in FWS ECOS https://ecos.fws.gov/ecp/. One Range One Range represents a single dataset that delineates the FWS Current Range and Species List Area (SLA) for species. These data inform the public of where the species may occur on the landscape and provide the basis for generating species lists in Information for Planning and Consultation (IPAC). One Range data represents...
FWS 2018 Species Status Assessment (SSA) report avaialble through FWS ServCat.
This dataset represents USFWS Whitebark Pine (WBP) (Pinus albicaulis) Species Distribution Modeling (SDM) extent used for WBP 2023 range update, attributed with USFWS 2018 WBP Species Status Assessment (SSA) Analysis Unit (AU) names. The polygons contained in this shapefile delineate the modeling extent for USFWS WBP SDM work (2023) and represents the maximum extent for SDM and USFWS Current Range and Species List Area (SLA) for WBP. Polygons of this extent dataset attributed to match USFWS 2018 WBP SSA AUs and represent updated AUs capturing additional areas of occurrence identified in the 2023 range update.

This data is a series of 135 50m resolution raster layers representing the sea level rise models for heights by 2100 ( 0.3m,0.5m,1.0m,1.5m,2.0m) under Low, Medium, and High senarios. The time of the models initialize at 2005 and continue for the years 2020,2030,2040,2050,2060,2070,2080,2090, and 2100. The CRS of the data is EPSG 4437 , Puerto Rico and Virgin Islands . The purpose of this data set was to estimate impacts over time on terrestrial species habitat under various sea level rise models and scenarios.

Strategic conservation of at-risk species is a priority for the Northeast Region of the U. S. Fish and Wildlife Service (Service). We define at-risk species as those that are at risk of becoming threatened or endangered, that are in decline throughout their range, and for which we can make a positive change in the near term if we act collectively and strategically. Across the continent, freshwater mussels have experienced drastic declines. Over 74 % of the 306 species found in North America are in some state of imperilment, with 93 species federally listed as endangered or threatened. Many species are facing critical impairment where their continued existence depends on rapid, targeted intervention, while other...
Funding will be provided to Save the Bay, an organization based in Rhode Island that is developing cutting-edge runnelling techniques that are improving thousands of acres of marshes across the region. Save the Bay’s Restoration Director works with partners throughout the Northeast region, and regularly hosts partners in the field and via webinars to share tips and lessons learned on implementing these techniques. Funds will allow her to provide greater regional support in the form of training salt marsh practitioners and sharing evaluation results of runnelling effectiveness that will inform work throughout the Northeast. In addition to these funds, an additional $30,000 of Coastal program funding will supplement...
