Data were obtained as part of a project assessing risk to the federal and California listed endangered Yuma Ridgway's rail (Rallus obsoletus yumanensis) populations resulting from selenium contaminated agricultural runoff and to inform habitat restoration and management decisions. Four data sets were produced and used to analyze patterns of Yuma Ridgway’s rail (Rallus obsoletus yumanensis, renamed from Rallus longirostris yumanensis [R. longirostris yumanensis retained in taxonomy section until further updated in ITIS system, https://www.itis.gov/submit.html]) occupancy and inter-marsh movements and to estimate rail abundance and regional population size to assess extent of selenium exposure of Yuma Ridgway’s rail...
These data include site information for call count stations used to monitor secretive marshbirds, specifically Yuma Ridgway's rail (Rallus obsoletus yumanensis), at and near the Salton Sea and Sonny Bono Salton Sea National Wildlife Refuge (SBSSNWR) in 2016 and complete count information for four species of secretive marshbird [Yuma Ridgway's rail, Virginia rail (Rallus limicola), Sora (Porzana carolina), American bittern (Botaurus lentiginosus)], detected among surveys at those sites between March 8 and April 17, 2016. Also included is location information from Yuma Ridgway’s rails marked with radio-downloaded GPS transmitters and tracked between April 4 and November 17, 2016.
