The data was developed from Map 1 on page 5 of Introduction to the California Condor by Snyder and Snyder, 2005. The data represents what the authors described as the "approximate range of the California Condor in about 1800". In early historical times, the authors described the California Condor as being widely distributed along the west coast of North America, from present day British Columbia in Canada to the mountains of northern Baja California in Mexico.

Oral sylvatic plague vaccine baits (SPV) and placebo baits were distributed once annually from 2013-2016 on treated and non-treated paired plots from 2013-2016. Black-tailed prairie dogs (BTPD) were live-trapped and permanently marked with passive integrated transponders and ear tags on 4 pairs of plots each year from 2013-2017 to provide capture/recapture data for use in estimating BTPD survival. The first data set (CMR_SPV_RAW_CAPTURE_DATA.csv) lists all captures and associated covariates with each line representing data from a single prairie dog. The second data set (CMR_BTPD_WEIGHTS.csv) lists the weight and associated information for each prairie dog at each handling. The third data set (CMR_FLEAS_BY_HOST.csv)...
Fishes of the Upper Colorado River Basin have one of the highest levels of endemism in the United States. The range and abundance of these fish has declined over the last century and continues to decline as a result of legacy impacts from past management practices, current water management, interactions with non-natives, and other impacts. Seven of these fish are considered imperiled by the American Fisheries Society and four are listed as endangered by the U.S. Fish and Wildlife Service. We applied a complementarity-based approach to develop priority ranks (0 – 1; low to high) for catchments in the Upper Colorado River Basin. We used methods and a framework that we had previously developed for the Lower Colorado...
FOREWORD The abundance and distribution of Pacific lamprey (Entosphenus tridentatus, formerly Lampetra tridentata) has significantly declined throughout its range over the past three decades. Many factors have contributed to this decline, including: impeded passage at dams and diversions, altered management of water flows and dewatering of stream reaches, dredging, chemical poisoning, poor ocean conditions, degraded water quality, disease, over-utilization, introduction and the establishment of non-native fishes, predation, and stream and floodplain degradation (Luzier et al 2009). Mitigation and restoration actions focused on habitat restoration of salmonid species within tributary habitats may also have contributed...

Seedskadee National Wildlife Refuge Complex includes: Seedskadee National Wildlife Refuge and Cokeville Meadows NationalWildlife Refuge. Seedskadee National Wildlife Refuge (NWR) is located in southwestern Wyoming. The name Seedskadee originated from the Shoshone Indian word "Sisk-a-dee-agie" meaning "river of the prairie hen." The 27,230 acre Refuge protects a mosaic of riparian, wetland, and upland shrub habitats along 36 miles of the Green River. The river is an oasis that bisects the vast high desert sagebrush plains of southwest Wyoming. Seedskadee NWR was established in 1965 as mitigation for the loss of habitat when Flaming Gorge and Fontenelle dams were constructed. The riparian corridor is an important...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
