资源简介：
Dependent double-observer amphibian egg mass counts were conducted twice annually for three years (2009-2011) at seven vernal pools at Marsh-Billings-Rockefeller National Historical Park in Woodstock, VT. The goal of the project was to monitor amphibian productivity via egg mass counts, estimate population sizes of Wood Frog (Rana sylvatica), Spotted Salamander (Ambystoma maculatum), and Jefferson Salamander (Ambystoma jeffersonianum), and provide baseline data with which to assess the effects of forestry operations on these species.
