Many a good project has faltered for lack of these necessities. One type of project that has become popular in Maryland schoolyards is the stormwater wetland. Rich Mason of the Chesapeake Bay Field Office of the U.S. Fish and Wildlife Service explains that the typical stormwater pond, with its uniform geometric shape, smooth bottom contour, and steep slopes, provides neither a diverse habitat for wildlife nor safe access for students. These changes would include irregular shape, small islands, and a combination of deep pools and shallow benches for emergent wetland plants. Gently sloping sides and observation decks make for safe access.
School districts vary widely in their response to the liability issue in relation to ponds.
If fencing is required, the enclosure should be large enough to allow for a vegetated buffer area around the pond and room for groups of students to work. A Place to Grow Planning the Schoolyard Environment Cameron Elementary School in Fairfax County, VA, has taken the habitat idea in a somewhat different direction. Their courtyard sports a barn full of goats, rabbits, chickens, and ducks. Our kids are city kids who would otherwise never have much interaction with animals. When Cameron was renovated, the district built them a barn and washdown area plus benches and tables.
