Wildlife
Public concern over the potential effects of timber harvesting and intensive forest management on wildlife has focused primarily on the decline or loss of large, charismatic species such as the spotted owl, grizzly bear, and timber wolf. Because of the relatively small size of the harvest units used in this experiment, it is not possible to evaluate responses to level or pattern of retention by these and other wildlife species with large spatial requirements. However, there are a broad array of other taxa (i.e., songbirds, small mammals, and amphibians) that represent major components of the native biodiversity in forested ecosystems, and some of these species may also be at risk. Because of their social, political, and biological significance, studies of wildlife are a central element of our research. Wildlife studies are designed to evaluate responses of diurnal forest birds, arboreal rodents, bats, forest-floor small mammals, and amphibians to different levels and patterns of green-tree retention.
An overview of the sampling strategies and predicted responses of selected wildlife species to the DEMO harvest treatments can be found in: Lehmkuhl, J.; West, S.; Chambers, C.; McComb, W.; Manuwal, D.; Aubry, K.; Erickson, J.; Gitzen, R.; Leu, M. 1999.
