Abstract:

Spalding’s catchfly (Silene spaldingii) is a rare plant endemic to bunchgrass grasslands, sagebrush-steppe, and open pine communities of the inland Pacific Northwest. It was listed as Threatened by the U.S. Fish and Wildlife Service in 2001 and is a high priority conservation concern for the Bureau of Land Management (BLM) in Idaho. In 2009, botanists from the Idaho Natural Heritage Program conducted surveys for Spalding’s catchfly at six sites on BLM lands in the Lower Salmon and Snake river canyons. We documented Spalding’s catchfly at four of the sites. In addition, we documented populations of five other species of conservation concern: broadfruit mariposa lily (Calochortus nitidus), Palouse thistle (Cirsium brevifolium), spacious monkeyflower (Mimulus ampliatus), Columbia Plateau or black spines cactus (Pediocactus nigrispinus), and scabrous goldenweed (Pyrrocoma scaberula).
