Yosemite National Park has long been the subject of botanical work aimed at describing the abundance and variety of plant life of the area. In spite of the fair degree to which the park’s flora is understood, information on the current status of listed plant species has lagged in the past two decades. To address this need, the U.S. Geological Survey entered into an agreement with the National Park Service (NPS) to update information on listed species occurring in the park, to determine population status of the highest priority species, and to create predicted habitat models for a subset of those. USGS worked with the Park Botanist to revise the park’s special status plant list, adding species newly documented in the park, those for which we uncovered evidence of occurrence, and new species listings. For each taxon, we provided information on listing status, distribution, habitat, elevation range, flowering period and rationale for inclusion on the list. Following survey work in 2003 and 2004, we proposed additional candidates for the park list. These were compiled using the same procedure of evaluating evidence of occurrence, distribution and listing information. The result is a list composed of 151 taxa that include four state-listed species, 13 Forest Service Sensitive taxa, and 62 taxa listed by the California Native Plant Society (CNPS).
