Rodhouse TJ and Garrett LK. 2008. Camas monitoring at Nez Perce National Historical Park and Big Hole National Battlefield: 2008 Annual Status Report. Natural Resource Technical Report. NPS/UCBN/NRTR—2008/133. National Park Service. Fort Collins
The UCBN has instituted a long-term citizen science-based monitoring program for detecting status and trends in camas (Camassia quamash) populations in Big Hole National Battlefield (BIHO) and Weippe Prairie, a unit of Nez Perce National Historical Park (NEPE). This report details the status and trend estimates obtained from the first four years of mointoring camas lily populations in the Weippe Prairie site of Nez Perce National Historical Park and Big Hole National Battlefield. Overall trend estimates are stable to slightly increasing. Camas populations across the two parks vary widely and the two largest populations, which occur in Weippe Prairie, are still below historic estimates of camas abundance. Invasion by orange hawkweed and sulphur cinquefoil in Weippe Prairie, as measured by frequency of occurrence in camas plots, appears to be stable or slightly decreasing. No weeds are currently being monitored in the camas meadow at BIHO.
