This dataset depicts staffed visitor stations within the Pacific Southwest Region of the U.S. Fish and Wildlife Service. Staffed visitor stations may be refuge offices that are open to the public during specified hours, or may be dedicated visitor centers. This dataset does not include kiosks or other areas which contain information for visitors but are not staffed. The locations of these stations are based on the USFWS Corporate Master Table, with additional editing and updates based on the input of field and visitor services staff.

The Hydrology Line Feature Class defines linear hydrographic features on RSL and in the region of hydrologic influence (RHI). The line feature class is composed of NHD Plus streams outside of the refuge borders in the region of hydrologic influence (RHI) and more detailed digitzed canals, ditches and streams on RSL based off 2010 National Agriculture Imagery Program (NAIP) 1 meter aerial imagery.

Sediment grain-size distributions, stable carbon isotope ratios (d13C), total carbon to total nitrogen ratios (C:N), short-lived radionuclides (Beryllium-7, Cesium-137, and Lead-210), concentrations of 76 parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and concentrations of 33 per- and polyfluoroalkyl substances (PFAS) were measured in the northern reach of San Francisco Bay (San Pablo and Suisun Bays), and in stream beds of the lower reaches of Napa River and Sonoma Creek, 5 months and 20 months after the 2017 Atlas and Nuns wildfires. New sites for sediment geochemistry analyses added 20 months post-fire included the lower reaches of Petaluma Creek and Suisun Slough, and in marsh sediment on Napa...

This data set depicts the facility point features (i.e. gates, boat launches, blinds) at the Colusa National Wildlife Refuge in Colusa County, California. This facilties dataset was heads-up digitized using aerial imagery. Certain facility features (gates) were snapped to the Sacramento National Wildlife Refuge Complex - Roads dataset.
This presentation aired as part of the Great Basin LCC webinar series on November 1, 2017. The presentation was given by Dr. Jim Sedinger and Phillip Street of University of Nevada Reno and Shawn Espinosa of the Nevada Department of Wildlife.Description: This project uses management-related variation in grazing by both feral horses and livestock as well as five years of field work to assess how both Greater Sage-grouse and the habitats on which they depend might be influenced by grazing. The research team monitored radio-tagged sage-grouse and vegetation on Hart Mountain and Sheldon National Wildlife Refuges as well as lands managed by the Bureau of Land Management (BLM) south and west of Sheldon from 2013-2016....

Shallow subsurface electrical conductivity was mapped at Wigeon National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 25 line-kilometers (km) of data were acquired over an area of approximately 2 square-kilometer. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey path;...

Shallow subsurface electrical conductivity was mapped at Northeast National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 14 line-kilometers (km) of data were acquired over an area of approximately 2 square-kilometer. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey...

Shallow subsurface electrical conductivity was mapped at Jerde National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 10 line-kilometers (km) of data were acquired over an area of approximately 1 square-kilometer. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey path;...

Shallow subsurface electrical conductivity was mapped at Westgard National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 21 line-kilometers (km) of data were acquired over an area of approximately .5 square-kilometers. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey...
