Comparison of methods to estimate population density of Pacific giant salamanders in small streams of the southern Oregon Cascades

Creator:

Leuthold, Niels C.

Abstract:

I compared hand sampling, two-pass multiple removal sampling, mark-recapture and catchability-based population estimates for the Pacific giant salamander (Dicamptodon tenebrosus) at 22 sites in 11 streams of Cascade Mountains of Oregon. Mark-recapture and catchability-based population estimates were not significantly different (p 0.86). Hand sampling and two-pass multiple removal population estimates...
