An herbarium is like a library, but instead of books, it houses carefully preserved plant specimens from a specific geographic area.
These collections are vital to the health and wellbeing of our natural spaces. Since they are often compiled over many yearsâsometimes even decadesâherbariums offer an invaluable record of how plant species and their ranges have changed over time. Many also preserve the genetic material of these plants through seed banks and other conservation methods. Beyond their scientific importance, herbariums inspire a deep appreciation for nature in all who witness their beautifully pressed specimens.
Herbariums are truly remarkable, which is why Save Barnegat Bay is proud to have contributed to one of the most comprehensive collections in New Jerseyâat Island Beach State Parkâthanks to the dedication of our principal botanist, Linda Kelly. Linda, one of the state’s foremost botanists, has spent nearly two decades [INSERT ACTUAL TIMELINE] collecting nearly every plant species, both on land and in water, that inhabits Island Beach State Park. This collection is known as the Emily deCamp Herbarium.
The Emily deCamp Herbarium was founded by the deCamp family and friends, all passionate nature enthusiasts who wanted to promote a deeper connection to the environment through education and engagement. The herbariumâs mission is to showcase the rich biodiversity of New Jerseyâs native plant life by:
- Illustrating the intricate “chain of life” in a way that captivates and educates,
- Empowering the public to begin exploring and understanding their own local ecosystems.
This special collection is housed at both the Forked River Interpretive Center and Coast Guard Station 112 (a former Coast Guard station) in Island Beach State Park, south of Seaside Park, NJ, and at our EcoCenter at 117 Haines Rd, Toms River. We are also honored to share that the seeds from these plants are preserved at Georgian Court University, largely due to the efforts of our late, beloved board member Dr. Louise Wooton. Louiseâs passion for Barnegat Bay, her dedication to its biodiversity, and her unwavering commitment to dune ecology were integral to both her lifeâs work and our continued efforts to protect these ecosystems.

The Plant Communities: An Overview
There are nine distinct plant communities at Island Beach State Park. While the above illustration may suggest a clear, linear progression of these communities from the bay to the ocean, this is a broad generalization. Some communities, like freshwater wetlands, can be found outside of these typical zonesâsuch as along the A13 trail east of the thicket. Similarly, the tidal marshes that dominate the southern end of the park give way to bayshore communities in the middle and northern sections of the park.
Submerged Aquatic Vegetation
Eelgrass and widgeon grass are submerged aquatic vegetation (SAV) that provide a habitat for many marine animals. Acting as a nursery, juvenile wildlife have higher survival rates here than in sandy soils. Migrating waterfowl, especially brant, are dependent upon this habitat.
Bayshore
Racks of eelgrass, discarded shells of animal life, roots from undermined cedar trees, and stands of Phragmites are representative of the bayshore community. In this area that battles erosion, plants protect the shoreline from damaging waves and winter ice, while trees serve as nesting sites for egrets and herons.
Tidal Marsh
Tidal marshes teem with life. The sunâs energy, tidewater, and plants make this one of the most productive environments in the world. Grasses help build the marsh, creating habitats for a multitude of animals. The sheltered waters serve as a nursery and haven for many marine species as well as New Jerseyâs largest osprey colony.
Freshwater Wetlands
Freshwater wetlands occur in areas with depressions and a high water table. Vegetation provides cover for wildlife that depend on fresh water. This community is essential for muskrats, insects, turtles, and frogs. Migratory waterfowl find a variety of food in these areas. Visitors are surprised to find cranberries growing near the pounding surf.
Maritime Forest
The maritime forest is a nationally significant plant community. The diversity of plants is extremely unusual for a barrier island. Slow growing, salt-tolerant trees dominate. Atlantic white cedar, pitch pine, red cedar, American holly, willow oak, sweetbay magnolia, and the southern red oak create a unique habitat.
Edge
An array of wildflowers blooms along the road edge. This narrow area has the greatest number of plants due to seeds being introduced by cars, birds and man. Even though many of these plants are annuals, they create a patchwork of color during the summer and provide a habitat for rabbits, birds, and even red foxes looking for food.
Thicket
The thicket is impenetrable to man, but ideal for wildlife. Decreasing amounts of salt spray and an increase in soil moisture support many berry-producing shrubs, trees, and vines. They provide cover and rich food sources for migratory songbirds and many other wildlife species.
Secondary Dunes
The harsh environment is also obvious in the secondary dunes. Salt spray pruning shapes the trees and shrubs, creating the gentle curves of this landscape. The dry, salty soil is tolerated by beach plum, black cherry, goldenrod, poison ivy, and beach heather. This community provides the most colorful botanical displays during the spring and fall season.
Primary Dune
Primary dunes are the first line of defense from the ocean waves. American beach grass, sea rocket, and seaside goldenrod survive salt-laden winds and dry soil conditions. Beach grass stabilizes the dunes, sea rocket provides protective habitat for beach nesting birds, and seaside goldenrod supplies a valuable food source for Mexico-bound monarch butterflies.
