The Peters Mountain mallow is a fire-dependent herbaceous plant species endemic to Peters Mountain, Virginia. Its population declined over the twentieth century, likely because of fire exclusion. We used firescarred trees to reconstruct the fire history of Peters Mountain (Hoss et al. 2008) and found that fires occurred frequently in the past, before fire protection became commonly practiced. The mean fire interval for the site was 2.5 years, and most fires occurred during the dormant season (spring or fall). Fire frequency is lower today. In 2005, at the time of our fieldwork, 29 years had elapsed since the last fire. The results suggest the need to reintroduce fire to restore the Peters Mountain mallow and its habitat.
