Abstract

An abundance and demography survey was conducted on Chinese Paddle-tail salamanders, Pachytriton brevipes, found within the Valley of the Wild Monkeys Park in Huangshan, China. Established mark-recapture sampling techniques were used to investigate population size of this species within the park's streams. Digital photographs were taken of all individuals encountered in order to identify recaptures in a non-invasive manner. There were 56 adult individuals encountered with six recaptured in Y A2 stream and 12 individuals with five recaptured in the Y Al stream. Both Jolly-Seber closed population and Lincoln-Peterson open population models were used to estimate population abundance. Estimates were then compared to a pilot study conducted during the 2005 CWU-Anhui University cooperative field school, to evaluate population stability. The combined results suggest that adult population sizes are stable from year-to­year and individuals have small home ranges and low mobility, which could make them susceptible to management activities that fragment their populations.
