Summary

Data are the result of fixed-area, time-constrained searches for terrestrial salamanders within and nearby a wildfire-affected area of the Willamette National Forest, OR. The spatial extent of the study was within one kilometer of the border of the Clark fire that burned an area of 2,009 ha in 2003. Site surveys occurred during March and April, 2005. An important feature of the data is that 100m2 sub-plots (nested within plots) were repeatedly searched for terrestrial salamanders independently up to nine times so that variation in the probability of capture could be estimated and accounted for concurrent with estimates of occupancy probability.

Purpose

Prior to our study, researchers studying short term impacts of wildfire on terrestrial salamanders in western North America consistently observed greater numbers within burns compared to nearby unburned areas. This observed pattern conflicted with the known physiology of these species and with landscape-scale associations of salamanders with forest stand age. We hypothesized that the observed pattern was largely the result of differences between burned and un-burned areas in the conditional probability of detecting individuals given presence; the salamanders that were present were easier to find in the burns because the structural complexity of ground cover was much reduced by the fire. Our study was designed to test this hypothesis and learn about true impacts of a burn on salamander abundance and site occupancy.
