Abstract/Summary

Over 2 years of surveys of 3 stream networks, stream salamander occupancy was better described by covariates related to the position of the site within the network than microhabitat features. Via simulation, we found that changes in occupancy can be detected by preferentially sampling headwaters, but causes of variation in extinction rates will require more intensive effort.
