NJDEP Vernal Habitat within the ENSP Highlands Extended Boundary
This data set is a product of the Landscape Project, Version 3.0, within the ENSP Highlands Extended Boundary, a pro-active, ecosystem-level approach to the long-term protection of imperiled and priority species and their important habitats in New Jersey. In 2001 ENSP partnered with Rutgers University Center for Remote Sensing and Spatial Analysis (CRSSA) to develop a method for mapping potential vernal pools throughout New Jersey. Through an on-screen visual interpretation of digital orthophotography, CRSSA identified over 13,000 potential pools throughout the state. A subset of these pools was field verified and confirmed, with an 88% accuracy rate (Lathrop et al. 2005), to meet the physical characteristics to qualify as a vernal pool. Prior versions of the Landscape Maps have not included mapping of vernal habitat areas. In accordance with N.J.A.C. 7:7A-1.4, the term "vernal habitat" includes a vernal pool - or the area of ponding - plus any freshwater wetlands adjacent to the vernal pool. The Department has included mapping of vernal habitat areas in Version 3.0 that relies upon data developed by the Department and Rutgers University Center for Remote Sensing and Spatial Analysis (CRSSA) to identify sites that should be field checked for possible identification as vernal habitats areas. DEP staff is in the process of field-verifying these pools. The Department also maps vernal habitat areas based upon on-the-ground assessment of sites not captured by the CRSSA mapping. In Version 3.0 of the Landscape Maps, all of the CRSAA-identified sites, as well a sites identified by on-the-ground reconnaissance, are categorized as either "potential vernal habitat areas" or "vernal habitat areas."
The purpose of the high_vp layer is to provide users with peer reviewed, scientifically sound wildlife data that is easily accessible and can be integrated with planning, protection and land management programs at every level of government (state, county, municipal) as well as nongovernmental conservation organizations and private land owners.
