In the vast Pinelands National Reserve of southern New Jersey, powerful vehicles trample protected sand dunes and drive circles through ancient ponds. Like in many wild places, "off-roading" has grown more popular here. Some of the off-roading activity is perfectly legal - provided it stays on established trails - but ignoring the rules is widespread.
As a gritty local conservationist works to protect habitat for threatened species, tensions flare with off-roading enthusiasts who fear their access to the forest will be restricted. Pine Mud is the first feature documentary to explore the controversial and intensifying problem of off-road vehicle damage on public lands.
