This IBA runs the entire length of the Arthur Kill with habitats including a narrow saltwater channel separating New Jersey from Staten Island; a contiguous habitat area on the northwest corner of Staten Island; extensive tidal and nontidal marshes; associated upland forests and several tributaries including the Elizabeth, Rahway and Woodbridge Rivers, and the Moses, Piles and Smith Creeks. This site also includes Union County Parks. The Arthur Kill Complex is extremely important as it provides some of the only remaining open space in this highly urbanized region.

Conservation Issues

The Arthur Kill Complex and its tributaries occur in one of the most urbanized areas of the northeastern United States. Habitat degradation from surrounding activities is a constant threat. Declining habitat quantity and quality can be attributed to chemical and nutrient pollution, stormwater and sewage discharge, stream channelization (and other changes in water flow), illegal filling and dumping activities, fragmentation, invasive species, mammalian predators, poorly planned development and other activities. Many conservation organizations including NJ Conservation Foundation (NJCF), NJ Audubon Society (NJAS), Trust for Public Land, and American Littoral Society have partnered with government agencies, local communities and private landowners to address these issues. NJCF and the NJAS conducted an inventory of the river and stream corridor in 1990. NJCF used this information to develop the Arthur Kill Greenways Tributaries Greenway Project and published Greenways to the Arthur Kill. This document identified priority wildlife habitats requiring protection and mapped potential greenways to protect the area?s resources. NJCF and other organizations have since worked to create a network of protected areas along the Arthur Kill. While many areas of this IBA are in public ownership and in need of appropriate management, many of the identified critical habitats are still privately held and need to be prioritized for conservation and/or acquisition.
