Abstract: Demographic modeling is used to understand the population viability of Furbish's lousewort, Pedicularis furbishiae, a perennial plant species endemic to the St. John River Valley in northern Maine. Environment‐specific summaries of demographic parameters (survivorship, growth, and fecundity) over four years, organized into stage‐based projection matrices, provide predictions of future population dynamics given a deterministic extension of past conditions. Stochastic modeling, using (I) empirically observed variation in demographic parameters, and (2) estimated rates of natural catastrophes, leads to predictions of extinction probability.
