Ninham Mountain State Forest locator map

Nimham Mountain, named after Chief Daniel Nimham of the Wappingers tribe, contains 1,023 acres in the town of Kent, Putnam County. This property is very popular with bikers, hikers and horseback riders and has an extensive network of trails and old roads. Proof of current negative Coggins certificate is required for all horses and out-of-state horse owners are required to produce a 30-day health certificate. Forest cover is mainly mixed hardwoods with some conifer plantations. Parking lots are on Nichols Street, Gipsy Trail Road, and Mt. Nimham Road.

Forest Land Management:

The forests of this state forest are managed to produce forest crops, maintain diverse wildlife habitats, and provide recreational opportunities while protecting aesthetics and water quality. A state forester's main tool in accomplishing these objectives is careful harvesting of trees.

Timber Management:

Timber stands are classified as either conifer plantations, meaning they were planted, or natural hardwoods, meaning they regenerate without human assistance. Stands of introduced pine, spruce or larch are planted in old farm fields, because they need open areas with direct sunlight to thrive. Such stands usually grow for about 80 to 100 years depending on species and soil conditions. They are usually managed by a series of partial thinnings. These thinnings provide sunlight openings in the canopy to encourage natural regeneration of native hardwoods. Removal of the conifer overstory in a final harvest allows hardwood seedlings to grow to maturity. There may be areas where the stand could be replanted with conifers if certain conditions exist.

Hardwood trees are not usually planted, as they spread vast amounts of seed and thereby naturally regenerate. Periodic thinning of hardwood forest stands through the sale of forest products gives the residual trees more growing space. This helps keep the forest healthy and provides openings for new seedlings, which in turn provide a revolving supply of food and cover for wildlife and are a source of future crop trees.

Hardwood stands are managed in either of two silvicultural styles, uneven aged or even aged. With uneven aged management, trees of all sizes and ages are maintained at all times throughout the stands, which will generally contain large trees giving an illusion of old growth. At Nimham Mountain, the hardwood stands were harvested just prior to state ownership. With even aged management, all of the hardwood trees within the stand are maintained at about the same age.


Users of the trail system may observe forest management practices which may at times disrupt trail use. Planning for multiple uses of the forest lands considers all disruptive impacts.

Fire Tower:

(Closed 5/4/15 through 5/8/15 for repairs) Located in the Taconic Hills north of New York City in Putnam County, Mount Ninham Fire Tower was built by the State of New York and the CCC in 1940. The 82'6" International Derrick Model 1937 tower LS-40 with 7' x 7' metal cab is located on state forestland. Although not used for fire detection in many years, it is maintained as a radio repeater site. Vandals burned the observer's cabin in 1994. Restoration of the tower was undertaken by the Town of Kent Conservation Advisory Commission.

State Forest Regulations:

Anyone enjoying this multiple use area must observe these rules which protect both them and the forest environment.

Volunteer Projects:

DEC appreciates public assistance. Volunteer projects will be considered if consistent with management policy and legal constraints. Volunteer projects are always subject to DEC supervision.
