Englewood Flat Rock Nature Preserve
Englewood’s Flat Rock Nature Preserve consists of 150 acres of second growth woodland, wetlands, meadows, gardens and ponds and nature building managed by Flat Rock Nature Association, a non-profit organization which hosts educational programs. 75 acres of the preserve are city owned Green Acres lands and 75 acres consist of the former Allison Woods Park which officially became part of Flat Rock Nature Preserve in 1988.

The preserve is surrounded on the north, south and west by dense residential housing. Englewood Cliffs is to the east of the preserve. Flat Rock Nature Preserve is a remnant section of a once massive hardwood forest on the western palisades. This forest remained intact until about 1859 when large scale logging occurred to provide railroad ties for the northern railroad which had extended into Englewood. Overtime, the forest grew back on land that was to become the Flat Rock Nature Preserve.

Over the years, several development proposals threatened the forest. In 1900, a few acres of the future nature preserve experienced quarrying which occurred until 1925. Today, the staging area of the quarry is the present day parking area of the nature center. A handicap accessible .1 of a mile boardwalk, constructed in 1989, goes near cliffs that were exposed during the quarry operations.
Quarry Boardwalk

Around 1907, a huge cemetery was proposed for the woods of Flat Rock but was declined by the city due to the land being unsuited for this purpose. In 1927 Paterno Construction Company bought land in the future preserve in order to construct residential development. Roads were constructed throughout Flat Rock’s forest. Construction of the houses was soon to follow but the great depression occurred effectively canceling the development. The roads became the foundation of the present trails found in the nature preserve. Over the next few decades new development threats came and went but the woods remained.
In 1968, the citizens of Englewood voted to approve a city bond issue to acquire and preserve the remaining open land in Englewood. In 1973, the organization that would become Flat Rock Nature Preserve was formed to manage the preserved open space.
Flat Rock Brook
Flat Rock Brook
Flat Rock flows into the preserve from the north. The brook is a tributary of the Overpeck Creek (Flat Rock’s confluence with the Overpeck Creek is just south of the border between Englewood and Leonia) which is a tributary of the Hackensack River. Flat Rock Brook is classified as FW2-NT (Fresh water, non-trout). The water quality has been designated as poor as indicated by the variety and number of sampled invertebrates. The water quality was tested by the Flat Rock Brook Nature Association which formed a stream study team to evaluate the health of Flat Rock. Recently, the Flat Rock Brook Nature Association received a grant of $9, 625 to help restore Flat Rock Brook by encouraging native plant species and removing invasive exotic plants. The grant was received from the Watershed Institute.

Flat Rock Ponds
Flat Rock Brook Nature Preserve features two ponds, Quarry Pond and MacFadden’s Pond.
Turtles in Quarry Pond
Quarry Pond is located to the south of the preserve near the nature center’s building. Quarry Pond has not been dredged since the 1970s. Sediment from nearby trails have been filling in the pond causing decreasing oxygen levels. Duckweed, an aquatic plant, has taken over the pond. In the fall of 2010, city officials voted to use funds from an unused 2007 bond ordinance to dredge the pond. If the pond does not get dredged, it will disappear and become a marshland which seems to be the fate of MacFadden’s Pond. MacFadden’s Pond is found in the northern area of the preserve. The pond was formed by the damming of Flat Rock Brook as it enters the preserve from the north.
MacFadden's Pond
The city of Englewood approved a dredging project for the pond in 2007 but when the cost to dredge the pond was found to be more than a million dollars, the dredging plan was canceled.
Trails
Red Trail
In addition to the quarry boardwalk, the preserve features over three miles of trails. The red trail is the longest at 1.2 miles and traverses the heart of the preserve and helps to connect Macfadden’s Pond with the nature center. The white trail, at .6 encircles the nature center and goes through gardens and around Quarry Pond. The .6 orange trail traverses in the western section of the preserve near Flat Rock.
Orange Trail
The yellow trail goes over a mystery bridge (called a mystery because the bridge appeared mysteriously one weekend) near Macfadden pond and back to the red trail. Click here for a trail map.
