NJ 03625 The coastal zone features a diversity of wetland types of varying size, type and importance; from large forested fresh water wetlands tonarrow strips of salt marsh. Development can adversely affect adjacentwetlands through increasedrunoff, sedimentation and the introduction of chemicaland thermalpollutants. Buffer zones arestripsof vegetatedland,composed in many cases of natural ecotonal and upland plant communities which separate development from environmentally sensitive areas and lessen these adverse impacts of human disturbance. In addition,buffer zones provideerosioncontroland flood protection forresidentialareas. The definition of buffer widths appropriate to provide adequate protection to wetlands under different development situations has long been a point of contention. On-site soil characteristics, vegetation cover, topography, climate, and land use patterns, and human/wildlife/plantpopulation densities all determine the extent of development impacts and, consequendy, the appropriatebuffer width. Many states have set a minimum allowable wetlands buffer width and increasethe distancedependingon the intensity and type of land use. Widths ranging from 0 to 1000 feet have been variously set with andwithout data support. If the establishment ofeffecdve buffer zones is to be incorporated into management policies, then there hasto be supportingdata. Additionalstudies areneeded to define the criteriaaffecting effecdve buffer width. 781
