This matrix of private, municipal and state lands includes the Manasquan Reservoir, Howell Park, Allaire State Park, and Manasquan Wildlife Management Area. The Manasquan River meanders through areas of mixed upland forest, forested wetland and suburban developments before widening upon its approach to the Atlantic Ocean. The open waters near the mouth of the river offer refuge for wintering waterfowl. This IBA is contains the Manasquan River Natural Heritage Priority Site. Designated by New Jersey Department of Environmental Protection, Natural Heritage Priority Sites are considered the state?s most significant natural areas.

Conservation Issues

High intensity development has impacted the area and ongoing development pressure adjacent to protected lands continues to threaten the integrity of this IBA. The loss of natural filtering systems such as forests and open marshes has degraded water quality and habitat for waterfowl and shorebirds. As small areas of forest are lost, the remaining forest fragments become less favorable for forest interior birds. Overabundant deer and invasive plants, such as garlic-mustard (Alliaria petiolata), common reed (Phragmites australis) and Japanese stilt grass (Microstegium vimineum), also threaten habitat quality. The Manasquan River Watershed Association has developed a management plan to protect the area?s natural resources.
