Harold N. Peek Preserve
Alert During this public health crisis, Natural Lands’ nature preserves remain open to the public as places to engage in outdoor activity, such as walking, hiking, or running, which are considered allowable individual activities as part of the stay-at-home orders for both Pennsylvania and New Jersey. Social distancing must be maintained. If the parking lot is full please visit at another time. All public facilities, including restrooms, are closed to the public until further notice. Thank you for your understanding.
Located along the freshwater, tidal Maurice River, the Harold N. Peek Preserve is home to some of the healthiest wild rice marsh in southern New Jersey. This wetland habitat is an excellent place to observe a wide variety of birds, especially migrating waterfowl and raptors. The preserve is part of the Maurice River Corridor “Important Bird Area” (a National Audubon Society designation).
Native wild rice is an exuberant grass. The species growing at the Harold N. Peek Preserve, Zinzania aquatica, is an annual, which means it only lives for one year. In May, the first leaves appear. By the time the plants flower mid-summer, they’ve grown nearly nine feet tall. In late-August, the seeds—rice kernels—ripen. Many are eaten by huge flocks of Red-winged blackbirds that are—in turn—pursued by Sharp-shinned and Cooper’s Hawks. But many more seeds fall into the water and mud where they’re eaten throughout the winter months by waterfowl such as Green-winged Teal, Mallards, and Northern Pintails. Those seeds the waterfowl miss become next year’s plants.
A mature Atlantic white-cedar (Chamaecyparis thyoides) swamp discharges tea-colored water to the marsh in the southeastern corner of the preserve. Cedar was harvested extensively in southern New Jersey for two centuries—the tannin in cedar bark was used to cure leather—and, consequently, few large cedar swamps in the region remain. Cedar-dominated forests like the one found here are ecologically unique and globally rare; they provide vital resources to a wide variety of wildlife and plant species, many of which are threatened or endangered.
Another native plant of particular interest is the prehistoric ground pine (Lycopodium dendroidium) that forms a six-inch evergreen carpet at several locations within the preserve. While it looks like a tree, ground pine is actually a type of club-moss: plants that reproduce by spores rather than seeds. These spores contain lypodine, once used as an explosive in fireworks. When mixed with air, the spores are highly flammable.
In the Paleozoic Era (about 300 million years ago), the ancestors of modern-day club-mosses reached gigantic proportions. These huge plants, some up to 200 feet tall, eventually transformed into the extensive coal beds that humans still mine as fossil fuel.
Harold N. Peek Preserve was established in 1992 and expanded in subsequent years. Harold Peek, who lived on the property with his family for 35 years, was a commercial fisherman who grew up hunting and trapping in the marsh, and harvesting oysters in Delaware Bay. The Peek’s modest home now serves as the New Jersey field office.
In the early part of the 20th century, much of the property was farmland. Dikes that once separated the marsh from the main river channel made it possible for farmers to raise hay, corn, and other crops. Others planted apple orchards, the remnants of which present occasional canoeing obstacles in the river.
