In addition to the
politics of the Oak Ridges Moraine, Happy Valley Forest faces a number of political and social issues. Since the late 1990s,
ATV use throughout the forest became a concern, both because the vehicles create noise, and because they cause damage to various plants; some indigenous plants are in danger of
