Wind turbines in Judith Gap, Montana

Wind energy is emerging as a sustainable, domestically available energy source. However, development of wind farms does impact wildlife habitat, bird mortality, and migratory bird routes. Scientists and their partners at NOROCK are studying these impacts and working towards developing predictive tools for land managers that assist in decision making and are protective of wildlife habitat and migration.

Still aren’t certain if climate change is a long term event or temporary trend? Why not look at those that will be most affected by the impacts of climate-change on our Rocky Mountain ecosystems. Scientists at NOROCK are doing just that by beginning two studies that will examine how climate change may be impacting the habitats of native fish and big game species. Full Story
