Restoring Damaged Ecosystems for the Future WYOMING (wpr) - The standard thinking on restoring damaged ecosystems in America is to try to reproduce the forests, grasslands, or lakes to the time before Europeans arrived here. But, a botany professor from the University of Wyoming has published a paper in the journal Science saying a new approach may be needed. Stephen Jackson co wrote the paper with a professor from Australia. Jackson told Addie Goss that using pre-European times as a model for ecological restoration is not always accurate because Native Americans impacted the land and ecosystems changed due to the climate. © Copyright 2009, wpr
