Invasive Strike Force Results

2015 Marked the fifth season of the Invasives Strike Force

Thanks to all the hard-working volunteers that helped us survey 1042 miles of trail for invasives in fiveyears!
We've almosted completed the 1340 miles of trail in the lower Hudson Valley New York and northern New Jersey areas that we began with in 2011. (Of course, now there are even more trails to survey!).
