Recently, there has been growing public awareness of both the finite nature and the
ecological effects of using fossil fuels to generate energy. This public awareness has
created an increased interest in renewable bioenergy resources, especially those produced
within a nation’s own borders. In light of this fact, I addressed whether the relative
abundance and body condition of amphibians and small mammals varied predictably
across forest plots that differ in the amount of woody biomass removal using drift-fence
arrays and visual encounter surveys. Results varied between species. However, only two
species (Blarina brevicauda and Lithobates sylvaticus) showed a clear negative response
to harvest. These data showed that the initial effect of harvest, or harvest and green tree
reserve type, appear to be important predictors for many of the amphibian and small
mammal species studied. To ensure forest sustainability, further study during stand
maturation will be necessary to better ascertain the long-term effects of coarse woody
debris harvest on amphibian and small mammal species.
