2nd year Conservation and Restoration Ecology (CARE) major Iraleigh Anderson used this slideshow as part of an oral presentation for Restoration Ecology class at Lakeland College. CARE is one of four majors available in Lakeland's environmental sciences diploma. Her topic was the American beaver and how this "original wetland engineer" can help with ecosystem restoration.
