Bear Swamp/Red Lion Preserve is located in the western portion of the Pinelands region near the small community of Red Lion. This IBA is a large expanse of primarily forested wetlands including pitch-pine (Pinus rigida) lowlands, Atlantic white cedar (Chamaecyparis thyoides) swamps and remnant cranberry bogs. The site is composed of three tracts donated to the New Jersey Natural Lands Trust (NLT) and many privately owned lands.

Conservation Issues

Only about a third of the Bear Swamp/Red Lion Preserve IBA is owned and managed by the NLT. Expansion of existing development and activities associated with residential development threaten the remaining habitats of this site. Protection of privately-owned lands can be achieved by promoting landowner incentives for protecting and managing habitat and by prioritizing parcels for conservation and acquisition. Control of invasive species, including southern pine beetles and gypsy moths, need to be implemented through appropriate methods. Forests should be protected as large, contiguous patches and managed to maintain a diversity of Pinelands community types including early successional habitats. Illegal off-road vehicle use is a major threat that requires control through increased law enforcement. Brown-headed Cowbird parasitism has been identified as a threat at this site.
