The goal of this study is to develop standardized survey and monitoring protocols for the four prairie species found in Oregon which are currently listed by U.S. Fish and Wildlife Service (USFWS): Bradshaw’s lomatium (Lomatium bradshawii), Kincaid’s lupine (Lupinus oregonus, formerly Lupinus sulphureus ssp. kincaidii), Nelson’s checkermallow (Sidalcea nelsoniana), and Willamette daisy (Erigeron decumbens). Survey protocols are designed to assess sites for the presence of the target species and, if found, to obtain simple estimates of population status, size, and threats in a relatively short period of time, in order to provide a maximum amount of data quickly and efficiently. Monitoring protocols are designed to facilitate population monitoring and comparison of data between years and sites. These protocols will facilitate the tracking of population abundance and evaluation of population trends, and will provide data useful for making management decisions and adjusting management strategies. Demographic study data collection protocols, although not the primary focus of this study, are provided to help those interested in assessing longer-term population structure and conducting species-specific modeling of population viability in order to have a better idea of the number and size of populations needed to ensure long-term persistence and recovery of the species.
