The forest is known as mixed mesophitic. Sugar and red maple, along with yellow-poplar, line the moist north and east-facing slopes. Mixed oaks occupy the warmer and drier south and west sides of the hills. Rhododendron thickets share the wet creek bottoms with hemlock. Mountain laurel, dogwood, sassafras and greenbriar occur throughout. An area of pitch pine can be found growing in the rocky face near Miller Trail.
This forest is mostly third growth, resulting from extensive timber harvesting by the Summit Lumber Co. of Uniontown around 1938-40. Many of the old logging roads and tram roads are in evidence, along with the dark brown sawdust piles that give mute testimony to the once active portable sawmills.
An abandoned farm field near the east end of Brocker and Tebolt Trails is reverting to brush and forestland. Several acres were planted with spruce and larch.
There are no restroom locations, and you must pack in potable water.
Camping in the Forbes State Forest is restricted to backpack-type camping. Camping out of vehicles or campers is not permitted. Permits for camping are required only if campers stay more than one night at any campsite. All campers are encouraged to obtain a permit in case you are overdue or if someone needs to reach you.
