Survey of colonial nesting waterbird species on the Atlantic Coast of New Jersey - 1989

Prior to this survey, the last survey was performed in 1985, and there was a vital need to repeat the survey since populations of these species can fluctuate widely from year to year. Regular surveillance is necessary to recognize population declines before they become serious. Additionally, the assessment of populations in the eastern United States depends on periodic statewide surveys. Region-wide surveys are conducted on a regular basis and the N.J. survey will supplement surveys performed in other eastern states. The data from the ENSP survey is the sole source of information on these species in N.J. and has been incorporated in the 1977 and 1986 federal review of these species (Erwin 1979, Andrews 1986). Since N.J. supports one of the largest populations of colonial waterbirds in the eastern U.S., completion of this survey is of vital importance to a regional assessment. This study also provides the basis for sound assessment of impacts from coastal projects potentially affecting colonial waterbird species. The mapping of the nesting areas provides the most current boundaries of nesting colonies and the composite overlays from previous surveys will yield a valid estimate of potential nesting sites in the entire Atlantic coastal zone. Colony maps provide the basis for assessing impact by developments that require CAFRA, Waterfront Development, Wetlands, and other permits. Information on the status of nesting areas is also important to the Bureau of Coastal Engineering and the U.S. Army Corps of Engineers in locating dredge spoil disposal areas needed for regular maintenance of the Inner-coastal Waterway and other navigation channels. Current information is required to avoid unnecessary protection of sites which are no longer viable as well as to identify sites newly in need of protection
