Silene spaldingii, Spalding's catchflyAbstract:
Spalding’s catchfly (Silene spaldingii S. Watson) is a rare plant endemic to the bunchgrass, sagebrush-steppe, and open pine communities of the inland Pacific Northwest. Large portions of these habitats have been eliminated by cultivation or degraded by livestock grazing and non-native plant invasion, and Spalding’s catchfly was listed as federally Threatened by the U.S. Fish and Wildlife Service (USFWS) in 2001 (USFWS 2001). Two long-term demographic studies of Spalding’s catchfly were conducted in canyon grasslands of west-central Idaho (2002-2013) to determine population dynamics to guide conservation and management of this species: 1) the FWS study funded primarily by the USFWS and 2) the BLM study funded primarily by the Bureau of Land Management (BLM). Demographic estimates were based on encounter histories using stage-based transition matrices and mark-recapture analyses. This report compares and summarizes the results of these two demographic studies.
