Description: In 2001 NJFW 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.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 here includes mapping of vernal habitat locations 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. These vernal habitat locations, all of the CRSAA-identified sites, as well a sites identified by on-the-ground reconnaissance, are categorized as either "potential vernal habitat location" or "vernal habitat location."
