Undergrads in the Smithsonian-Mason School of Conservation's exciting summer field skills course recently visited Leopold's Preserve to explore connections between forests, wetlands, and watersheds through hands-on fieldwork.
Students investigated the impacts of deer browsing by comparing vegetation inside and outside a deer exclosure, visited a rare upland depression swamp, and joined Park Manager Nick Davis for a tour of an active beaver wetland.
A trip highlight was seeing the beavers' engineering up close. The site features three levels of ponds, where it's possible to look up from one pond to view a dam holding back water in the pond above. From lodges to dams, students thoroughly enjoyed this firsthand look at how beavers shape the landscape around them.
