Forester evaluating hemlockState Forest Lands

NJ Forest Service monitors and maintains 775,000 acres of state-owned open space – that’s an area as large as the entire state of Rhode Island. These forests work hard – they produce clean water and air, absorb runoff, provide recreation, and are home to thousands of species of wildlife. To keep our forests productive, State Forestry Services monitors biodiversity, creates wildlife habitats, suppresses pest outbreaks, and restores ecologically significant areas.

Management of our forests incorporates the best forest stewardship principles derived from a forest management plan developed with public input.

These goals include:

- Research

- Education

- Public Notification

- Restore forest after pest or disease outbreak

- Encourage economic opportunity

Delaware & Raritan Canal State Park
Emerald Ash Borer and Restoration Project

- Mitigating the spread of invasive pest EAB and reducing hazardous ash along the 70 miles of towpath trails

- Removal and treatment will occur along towpath.

- To prevent spread of EAB, ash trees will be cut and left on site

- First state park to officially find EAB

- More information on EAB please visit

Be advised - Ash removal project currently shut down for timing restrictions.



Hacklebarney State Park
Superstorm Sandy Recovery

- Mowing of uprooted, toppled, and severely damaged trees from Superstorm Sandy.

- Control of invasive species like Japanese barberry, and wineberry.

- Planting of seedlings will occur if natural regeneration is unsuccessful.

- Fence out deer from eating seedlings.


Stokes State Forest
Oak Regeneration Project

- Generate a new population of mixed-oaks.

- Encourage a more resilient forest by promoting regeneration of oak.

- Project to being upcoming winter months.

- Tools to ensure a successful project will include deer fencing, prescribed burning, and invasive control as needed.


Brendan T. Byrne
Red Headed Wood Pecker Site

- Promote regeneration of shortleaf pine and mixed oak species.

- Retain and create snags (dead standing trees) for habitat and remove pine regeneration

- Combine multiple management practices to achieve ideal RHWP habitat.

- Increase recreational (birdwatching) value of the 12-acre site.

- Provide nesting, foraging and protection from ground predators.


Brendan T. Byrne
Magnolia Road Shelterwood

- Generate a new population of mixed oaks and pines through a shelterwood harvest.

- Follow harvesting activities with prescribed burning and site preparation to encourage establishment and regeneration
of oak and shortleaf pine species.


Double Trouble State Park
Superstorm Sandy Cedar Salvage

- Salvage the Atlantic-white cedar trees which were damaged and/or blown down during Superstorm Sandy.

- Simultaneously promote new AWC growth through a combination of management practices, including treatment with herbicide to help reduce competition from hardwoods, deer exclusion fencing, and replanting.

- Remove trees that pose a hazard of falling.

Sandy Damage

After Salvage


Double Trouble State Park
Rare Species Habitat

- Introduce disturbance (fire) to decrease fuel buildup (leaves and debris on forest floor).

- Open up the canopy with a shelterwood harvest, which will allow light to reach the forest floor.

- Leave patches of forest undisturbed to create a mixed and diverse favorable habitat for rare species.

- Improve health of trees remaining on site.


Washington Crossing State Park
Emerald Ash Borer Infestation

- Combat the spread of EAB and reduce the hazard of falling trees within the Green Grove Day Use area.

- Salvage and utilize the removed ash.

- Treat for invasive species.


Swartswood State Park
Preventative Ash Removal

- Remove ash trees as part of a larger preventative effort to combat the spread of EAB.

- Only remove trees located in and around high use areas posing the greatest risk.

- Enhance forest health and resilience.

Washington Turnpike
Wharton State Forest

- Purpose: Wildfire Strategic Risk Reduction through road maintenance of Washington Turnpike (25 acres total – 5 miles of road) and three silvilcutural thinnings (745 acres total).

- Road Maintenance included harvesting of trees along the shoulders (20 feet either side) and removal of stumps closest to the road edge for re-grading and re-establishment of roadside ditch to correctly drain the road as well as culvert replacement to restore road function and to overall restore fire break functionality.

- Silvicultural thinning included cutting of smaller trees lower in the canopy to reduce forest density, increase forest health, provide a strategic fuelbreak by breaking up the fuel ladder, and reduce risk of southern pine beetle attack.

- Completed: Tree harvesting along road, most removal of stumps, some re-grading of road, work remains active. Thinning of western section 125-200 acres total, work remains active.
