We studied a population of Plethodon albagula inhabiting an abandoned mine in Garland County, Arkansas, to test whether variables such as fecundity, diameter of egg, total number of eggs produced, and total number of clutches were influenced by precipitation or prescribed burning. We also compared ratios of juveniles to adults during summer, a period when P. albagula sought refuge in the mine, to determine if prescribed burning influenced certain life stages more than others. Comparing years before and after burning and accounting for the influence of precipitation, we did not detect a significant effect of the prescribed burn on any reproductive variable. However, we did discover a decline in some reproductive variables 1.5 years post-burning. There also was no decline in the ratio of juveniles to adults before or after the burn. Prescribed burning in the inactive season did not affect reproduction or age composition of the population of P. albagula.
