Previously, this land was owned by the Warren Manufacturing Company. Started in 1873 by John L. Riegel, this paper plant processed wood pulp from the forest into sheets of paper through steam-powered machinery harnessed by the river. The timber was also used to make
charcoal, which was sold to farmers as fertilizer. Mill workers stacked and burned the timber on man-made flat areas against the hillside called “charcoal landings.” The remains of several charcoal landings are still visible along the trails. Look for flat areas with very dark soil. Near Musconetcong Gorge, the towns of Warren Glen and Riegelsville were built by the paper company to house their workers. The company was more recently known as Fibermark, Inc. The county acquired much of the property in 1977, and smaller parcels have since been added, bringing the total area of the preserve to 523 acres.

HABITAT AND WILDLIFE This oak-hickory forest is a major food source for wildlife. Gray Squirrels and White-tailed Deer are common residents, and evidence of Black Bears in the park has been recorded.

The ravine and water seeps located in the park provide excellent habitat for reptiles and amphibians and can be identified by rocky areas with moss and ferns growing around them.

Several types of birds can be seen throughout the year. Evidence of woodpeckers, such as the Downy Woodpecker, can be found along the Nature Trail. Turkey Vultures and hawks can be seen flying above as they use the thermal pockets created by the Musconetcong Ridge. With the ample supply of acorns and nuts, do not be surprised if you come across a flock of Wild Turkeys in the park.

RECREATIONAL OPPORTUNITIES The trails at the park are designed for hiking only. Most of the trails range from moderate to slightly difficult. They take advantage of the smoothest grounds but are steep in some areas. This park offers beautiful vistas.

HUNTING In order to control the population of deer on park property, hunting is permitted. Hunters must obtain a special permit issued by the Division. Visitors between September and February are strongly encouraged to wear blaze orange or confine visits to Sundays. See additional information on the Hunterdon County Park System Controlled Hunting Program.

With the exception of park properties with reservable facilities, all properties are “carry in / carry out” and trash/recycling receptacles are
not provided. Please plan accordingly and do not leave any trash/recyclables behind.
