Matt Clark is Associate Professor and Director of Research (Minnesota Landscape Arboretum). The University of Minnesota Landscape Arboretum is a 1,200-acre public garden in Chaska, Minnesota, that attracts nearly 700,000 visitors per year. Best known for its beautiful display gardens, nationally recognized tree collections, protected natural areas and research activity, the Arboretum is easy to explore via paved paths, such as Three-Mile Walk and Three-Mile Drive, which are open year-round. Many miles of wooded trails, stone pathways and routes for cross-country skiers and snowshoers provide access to the healing power of nature in all seasons.
