Two at-risk species also benefit from the protection afforded by Stone Harbor Bird Sanctuary. Cope's Gray Tree Frog, abundant in the Sanctuary, is an endangered species in New Jersey. Monarch Butterflies, which thrive on the nectar provided by flowers in the Sanctuary's gardens, are currently under review for listing under the Endangered Species Act.

What is a Habitat Mosaic?
A habitat mosaic is a landscape in which several different ecosystems occur near each other. Mosaics are particularly rich in biodiversity because the individual ecosystems support different plants and animals.
The borders between habitats - transition areas - are also very important as many species use both habitats and cross between them freely. For example, some birds feed in grasslands and nest in forest edges. Likewise, some frogs, like the Cope's Gray Tree Frog, breed in wetlands and hibernate in woodlands.
Habitat mosaics provide for the animals that depend on specific habitats as well as those that rely on more than one habitat. Stone Harbor Bird Sanctuary supports
a habitat mosaic that includes forest, freshwater and tidal marshes, and meadows.
Atlantic Maritime Forest borders both a tidal salt marsh and freshwater marsh, creating a rich habitat mosaic supporting a great diversity of wildlife.

Bird Sanctuary Habitat Map
- Tidal Marsh
The tidal marsh is connected to the bay through a pipe running beneath 3rd Avenue. Salt water flows through tidal channels and spills into the cordgrass-dominated marsh. Fiddler crabs and small fish make their homes here and provide food for wading birds. - Freshwater Marsh
Hidden within the Sanctuary is a freshwater pond that supports more than two acres of freshwater marsh. The marsh is dominated by low-growing grasses, sedges, and flowering plants. Phragmites, the common reed, is an invasive plant that has invaded the freshwater marsh. The Borough is working to manage Phragmites. The freshwater marsh is home to a wide variety of frogs and toads, and used by many species of birds. - Successional Meadow
The successional meadow is highly productive and dynamic, and supports a diverse range of wildlife. Native grasses and forbs (non-woody flowering plants) predominate and provide abundant food. The low vegetation offers cover for birds and other small animals, while the open canopy allows light and heat to reach the ground - essential for reptiles and amphibians that can't generate their own body heat. This meadow is a system in transition, with woody shrubs and trees moving in. This type of shrub/scrub habitat is important for many bird species. - Upland Forest
The upland forest ecosystem is a remnant of the Atlantic Maritime Forest that once covered the Atlantic coast's barrier islands and coastal plain. This ecosystem has largely been lost due to development, existing now only in small patches. Within the upland forest, ancient trees adapted to wind and salt spray dominate, primarily American holly, sassafras, black cherry, and red cedar.
- Heron Overlook Path
Located off 3rd Avenue and surrounded by beautiful gardens, Heron Overlook provides a view of the saltwater wetlands - a popular heron feeding area. During spring and fall, Neotropical songbirds break their epic journeys here; in fall Monarchs swarm the flower gardens on their way south. - Meadow Walk Path
Also located off 3rd Avenue, Meadow Walk exists between two worlds: freshwater marsh to the left of the trailhead, saltwater marsh to the right. Herons and egrets hunt here in spring and summer, while songbirds enjoy the cedars and feed in the marsh year-round. - Egret Espy Path
The entrance to Egrey Espy in on 2ndAvenue. The path crosses a footbridge and ancient sand dune and enters a centuries-old remnant of Atlantic Maritime Forest, a reminder of South Jersey's past. Migratory and year-round resident birds keep this path alive with activity. - Holly Path
Located on 2nd Avenue, Holly Path meanders across ancient sand dunes, through Atlantic Maritime Forest with stands of sassafras, holly, and cedar, and past a 300-year-old holly tree. Black-crowned Night-Herons frequent this path, which is closed from March 1 to October 1 to limit disturbance and encourage the birds to use the site.

The Stone Harbor Bird Sanctuary is a wonderfully preserved microcosm of what the barrier islands of New Jersey looked like hundreds of years ago. As you walk along Sanctuary paths, it is easy to imagine the Lenni-Lenape Indians wandering through the maritime forest, crossing wind swept sand dunes, past groves of white cedar, birch, pine, holly and sassafras trees, taking time to drink water from a spring fed freshwater pond and then, fishing in the salt water meadows surrounded by herons and songbirds.(Submitted on August 13, 2026, by Pete Skillman of Townsend, Delaware.)
