Correct me if I'm wrong, but since Jungle Habitat's demise as an animal safari in the early '70's, the land had laid vacant and nobody 'owned' the land. Essentially the State took control but did not dedicate any use for the land. ATV/ Dirtbikers saw an opportunity and began shredding trails through the woods at JH. At some point the mtb community, such as JORBA, Town Cycle, etc, started building trails for mtb use. The government caught wind of this and said you can't just freely build trails since it is not a park nor private property. I believe JORBA lobbied (successfully) and the sanctioning bodies that regulate Ringwood and Ramapo took the orphan JH under their control. From what I understand is that JH would be considered a County Park, and therefore no ATV's allowed.
I ride JH (mtb) a lot and love the trail work, even assisted when I could, and I'd hate to see this great place closed to mountain bikers and utterly destroyed with just one weekend of ATV/ Motos. How fast do you think the switchbacks of Otter Slide and Animal Chute will be ruined?
