"Deer have been a blight on suburbia for a while now, munching their way through tract-housing gardens and making some highways extremely dangerous for motorists, as their populations have exploded. (In DC, where they live in abundant numbers in the city's biggest park, Rock Creek Park, they're known by neighbors as rats with antlers.) Deer are also radically changing places like the forests of the Adirondacks by devouring young tree shoots from the storied maples and leaving nothing but beech. But a new study finds that it's not just deer populations that are wreaking havoc on North American ecosystems. It's all of the large mammals that graze on plants."
