Population trends of Lomatium bradshawii before and after prairie fires: 1988- 1997

A USFWS recovery plan for L. bradshawii (Parenti et al. 1993) targets population monitoring and enhancement as two actions needed to meet recovery objectives for the species. Population monitoring alone will not contribute to the species’ recovery unless it is combined with rigorous analysis to identify populations at risk and evaluate enhancement techniques. The goal of this report is to evaluate the effects of fire on the population dynamics and trends of L. bradshawii at three federally-managed sites, from 1988 through 1997. Analyses of the effect of fire using transition matrix models (over the period of 1988-1993) have been reported previously and are update here.
