BLM OR-WA Population Monitoring and Effects of Grazing on Greene's Mariposa Lily on the Cascade-Siskiyou National Monument
The principle purpose of this project is to develop a partnership with individuals and organizations in order to improve the public's understanding of a rare endemic plant species that occurs in Southwest Oregon and Northern California. This research is designed to scientifically document the species population biology, habitat herbivory and response to differing management conditions within the range of the species including the Cascades Siskiyou National Monument and surrounding landscape. (1) Determine the effects of herbivory by wild and domestic animals (insects, small mammals, large mammals including deer and livestock) on Green's mariposa lily population processes and trends, and recommend effective management strategies to promote the species' viability within the Cascade¿Siskiyou National Monument (Basic Understanding and Applied Science Focus Area) (2) Identify climate drivers of population growth for Greene's mariposa lily and provide suggestions for management and or restoration to support the persistence of this species on the National Monument in the future (Applied Science Focus Areas). (3) Evaluate trends in plant communities associated with Greene's mariposa lily and how they relate to herbivory and climate to provide management recommendations for this species on public lands inside and outside of the National Monument (Basic Understanding and Applied Science Focus Areas).
