Edwin B. Forsythe National Wildlife Refuge




The Edwin B. Forsythe National Wildlife Refuge is located within Atlantic and Ocean Counties along the southern New Jersey coast. Approximately, 47,000 acres of salt marsh (80%), shallow bay, tidal flats, dunes, and pine forest are protected and managed by the U.S. Fish and Wildlife Service. These coastal habitats are especially crucial for birds that use the Atlantic flyway for fall and spring migration. There are also several threatened and endangered species that call the refuge home. Most of the refuge is relatively inaccessible to the general public. But, in Oceanville (800 Great Creek Rd., Oceanville, NJ 08205) there is a visitor center, an eight-mile wildlife drive, and  3.7 miles of trails that allows visitors to view the incredible flora and fauna protected in this reserve.

FLORA


At the beginning and end of the  8-mile wildlife drive there is typical maritime forest habitat. Typical trees include a mix of hardwoods such as Sassafras (Sassafras albidum), Red Maple (Acer rubrum), various oaks trees including Southern Red Oak (Quercus falcata), Post Oak (Q. stellata), and Black Oak (Q. velutina).  Assorted gymnosperms include Red Cedar (Juniperus virginiana) and Pitch Pine (Pinus rigida). Shrub layers and understory include Sweet Pepper Bush (Clethra alnifolia), Wax Myrtle (Morella cerifera), Bayberry (M. pensylvanica), Arrowwood Viburnum ( Viburnum dentatum) and Beach Plum (Prunus maritima). Vines include Virginia Creeper (Parthenocissus quinquefolia), Catbrier (Smilax rotundifolia), and Poison Ivy (Toxicodendron radicans).


Within the wetlands, fresh and brackish waters, you typically see a mix of Narrow Leaved Cattail (Typhya angustifolia), various Spartina species such as Spartina patens, Salt Marsh Bulrush (Schoenoplectus maritimus), Spikegrass (Distichlis spicata), Marsh Elder (Iva frutescens), Marsh Mallow (Althaea officinalis), Groundsel Bush (Baccharis halmifolia), and the invasive Common Reed (Phragmites australis). Of course, there are many other species through-out the refuge too numerous to mention!

BIRDS


The refuge protects and provides nesting sites for the federally threatened Piping Plover and other special species such as Black Skimmers, Least Terns, and American Oystercatchers. I did see Black Skimmers and American Oystercatchers along the drive. I really enjoyed watching the Black Skimmers gracefully “skimming” along the canals. Although I did not visit the refuge during the peak of spring or fall migration, I did manage to view a total of 55 bird species, about half of which were various waterfowl and shore birds. For most people, including myself, the Ospreys stole the show! Numerous nesting platforms are spaced out along the length of the 8-mile wildlife drive and every platform supported an Osprey family. The chicks were large and kept the parents busy bringing fish to the nest. It was awesome to watch the adults shred the fish and feed the young! One sad note, many of the Osprey nests had plastic shopping bags incorporated into the nest structure.

Barn Swallow, these birds were common at the begining of the 8-mile wildlife drive near the visitor center. They were nesting under the boardwalks.

 I asked two other birders and got two different answers.

Unfortunately, I just missed a rare visit by a Roseate Spoonbill (only the 5th or 6th time reported for the state), but a fellow birder did give me a tip about a nearby Tricolored Heron that is also an unusual visitor to N.J.

MAMMALS


I was amazed and pleasantly surprised by the diversity of mammals I observed within a relatively short time and small area. While driving along the 8-mile loop and exploring several of the shorter trails I observed White-tailed Deer (Odocoileus virginianus),  several Muskrats (Ondatra zibethicus), Gray Squirrels (Sciurus carolinensis), an Eastern Chipmunk (Tamias striatus), a Raccoon (Procyon lotor), and a River Otter, (Lutra canadensis). I observed one Muskrat cutting aquatic vegetation (sedges) and swimming with the plants towards the canal bank and out of my sight. Another Muskrat was feeding. It did not seem bothered by my presence and sat for quite a while eating vegetation. The highlight of one day was seeing a River Otter! It was swimming among the water lilies at the end of Gull Pond Road. I was so excited that I forgot to snap a picture before it dived back under the water and disappeared. This area is where I also saw the Raccoon. It was at the water’s edge and I think we surprised each other. The Raccoon quickly retreated into the thick brush. It was probably looking for turtle nests to raid. I had seen evidence all day of destroyed turtle nests. It was obvious that the eggs had not hatched naturally, the shells were usually some distance from the nest cavity and arranged in small piles. On another trip to the refuge a mink (Neovison vison) the road in front of my car.

REPTILES AND AMPHIBIANS

Often when I am hiking I will snap photos of plants and animals with the idea that I will make a more positive identification later. So, I was pleasantly surprised when looking at my photos that a toad I had seen along Jen’s Trail turned out to be a Fowler's Toad (Bufo woodhousii fowleri) a N.J. species of special concern. It is often confused with the more common Eastern American Toad (Bufo americanus). One way to separate the two species is to look at the back of the head. On Fowler’s Toads the parotid glands touch the postorbital ridge while on the Eastern American Toad there is a gap or small connecting spur between the parotid glands and postorbital ridge.

The Northern Diamondback Terrapin (Malaclemys terrapin) is the only turtle species, in the world, that inhabits brackish water for their entire life. On my first day visiting the refuge the turtles were everywhere! The females were in the forests, along the canals banks, in the roads, and even crossing bridges looking for suitable nesting sites. There was easily 100+ turtles sighted along the wildlife drive through the refuge. Cars were stopping and waiting for turtles to cross or carefully driving around them. Unfortunately,  many of the females were trying to dig nests and lay eggs directly in the gravelly roadbed. Many moved once cars approached and I hope they found safer more suitable nest locations. There was also much evidence that many of the nests had fell victim to raccoons and other predators. The “Conserve Wildlife Foundation of N.J.”  stated that, “ Only around 1-3% of the eggs laid actually produce a hatchling, and success rates of young reaching adulthood is also low.” The exact population status of the Northern Diamondback Terrapin in N.J. is not known. Other nearby states such as Rhode Island and Massachusetts have the turtles listed as endangered or threatened respectively. Many N.J. conservation groups are supporting studies and lobbying for more protection of this unique species. Oddly, on my other two visits on subsequent days I probably saw less than 10 Terrapins total!

Two other turtle species seen within the refuge was the Eastern Mud Turtle (Kinosternon subrubrum) and Common Box Turtle (Terrapene carolina).

INSECTS

I did not focus on insects, but several species were very conspicuous along the wildlife drive and trails in the refuge. One notorious species was the Greenhead Horsefly (Tabanas nigrovitatus). They are actually pretty flies with large emerald green eyes and yellowish bodies, but the females feed on blood, including human blood, and can deliver a painful bite. Simply opening your car door allows dozens to quickly enter and fly around the interior, annoying you even within the supposed protection of your car. As I drove around the refuge I was constantly lowering the windows enticing them to fly back out. What was really intimidating was the huge clouds of Greenheads that would follow the car even as you were driving! At one point, Alfred Hitchcock’s “ The Birds”  came to mind as I tried to avoid the biting swarms. I did spray with OFF insect repellant which helped some but,  over the years Greenheads have become fairly resistant to many commercial bug sprays and even with protection you still receive numerous bites. So, as I stood with my binoculars and camera I alternated between nature watching and swatting flies. I also suddenly understood the large occurrence of Purple Martin houses in yards and around parks in Southern N.J.

The other insect was much more passive and beautiful, this was the Monarch Butterfly (Danaus plexippus). Large populations of Common Milkweed (Asclepias syriaca), Butterfly Weed (Asclepias tuberosa), and other wildflowers grew along the wildlife drive providing food and shelter for the Monarchs and many other butterflies and insects.

The Edwin B. Forsyth Wildlife Refuge is definitely on my list of favorite wildlife viewing areas. For four dollars a day (per car) the 8-mile wildlife loop is the biggest bang for your buck!
