Here's a source for some unique NJ maps:
In conjunction with its newly adopted vernal habitats protocols, the NJDEP is providing mapping to assist in locating the vernal habitats so far identified and certified by the Department. The mapping is approximate, and will be updated and refined on an ongoing basis as more vernal habitats are certified. More detailed information on a particular vernal habitat can be obtained by contacting the Land Use Regulation Program at LURWEB@dep.state.nj.us
Areas highlighted in green on the New Jersey state map on the site represent USGS Quadrangles in which there exist vernal habitats. If you click on area representing the quadrangle, a detailed map will appear showing specific locations of the vernal habitats in that area. The example here is in the Wanaque Reservoir region.
