Pennsville in Salem County, New Jersey — The American Northeast (Mid-Atlantic)
Pea Patch Island Heronry
Wading birds are highly social and thrive in noisy crowded colonies. However, the habitat available for these birds is being threatened by oil spills, industrial pollution, and pesticides. Protecting the heronry is critical to the survival of these species. By observing the population of these wading birds, the health of the wetland can be determined. A low population can be an early warning sign of environmental changes in these areas.
The heronry shares Pea Patch Island with historic Fort Delaware. It is a designated nature preserve with limited access and is managed by the Division of Parks and Recreation.
