Mammalian abundance in riparian and adjacent terrestrial habitats prior to and immediately following forest harvesting in the Copper Lake watershed, Newfoundland
The Copper Lake Buffer Zone Study was initiated in 1994 to evaluate the effects of forest harvesting practices on mammalian, avian and piscine assemblages in a small watershed. This portion of the Copper Lake study evaluates mammalian abundance in riparian habitats both prior to and immediately foll...
