Aspen, Thursday, April 1
Aspen Center for Environmental Studies (ACES), at 7:30 p.m. Free tea and cookies will be available beforehand. Hosted by WW and ACES. Historical photographs of the Canadian Rocky Mountains taken in the early 1900s show the treeline elevation to be 500 feet lower than it is today. This presentation explores what caused such a significant ecological shift, where variations in the change occur, and other changes occurring in the treeline environment of the southern Canadian Rocky Mountains. The presentation will explain how the documentation of the impacts of anthropogenic climate change on a remote alpine landscape poses challenging questions for conservationists and restorations. Unlike the direct and localized impacts of mining or logging on ecosystems, climate change affects the treeline and alpine ecosystems in diffuse ways which become integrated into prior ecosystem functions over the long term. Traditional conservation and restoration strategies may not be logistically feasible or ethically appropriate. |
