Nearly one-third of that land lies below 100 feet elevation. Lake level on Champlain fluctuates seasonally from about 95 to 101 feet above sea level so much of the park is subjected to seasonal inundation. The forest type in these floodplain areas is uncommon in Vermont, found only around Lake Champlain. The North Hero example is noted for its size, relatively undisturbed condition, and rare flora habitat. The thick woods around the campground, and the fact that much of the property was farmed and pastured before becoming a park, have led to conditions favorable for wildlife.
Old fields are in stages of reverting to forest.
There is a diversity of habitats that land management in the park works to perpetuate. Fields are periodically mowed, burned, or cut back around the edges. Patches of one or two acres are clear-cut into the woods on a rotating schedule to create staggered openings in varied successional stages. Such habitat work pays off. Whitetailed deer are common.
