Jakey Hollow Natural Area, Protected area in Columbia County, United States.

Jakey Hollow Natural Area is a 59-acre protected area in Mount Pleasant Township, Columbia County, Pennsylvania, on a small tributary of Little Fishing Creek near Mordansville. About half is old-growth Northern Conifer Forest, with second-growth eastern hemlock, a few virgin hemlock, chestnut, red and white oak, American beech, black birch, black cherry, white ash and dozens of white pines over 100 feet tall. A glen lies within the hollow.

Jakey Hollow was originally part of a larger forest covering the region, and its hardwood trees are about 200 years old. Timbering was done in the hollow, and former logging grades are still visible. In the 1950s Ward Crawford and his brother bought the land and protected it; the Pennsylvania Department of Conservation and Natural Resources purchased it from Crawford in 1990. In the 1990s the natural area was part of the Wyoming State Forest.

The Ward Crawford Trail, an unblazed one-mile route, starts at the parking lot, drops into the hollow, crosses the stream and climbs to a field. Footpaths beside the stream were made by earlier visitors, and hunting is permitted in the area.

The Ward Crawford Trail is an unblazed, one-mile route starting at the parking area off Crawford Road; it drops into the hollow, crosses the stream at the bottom and climbs to a field, with 100 feet of elevation change. Footpaths also run parallel to the stream. The trail system is informal, so expect uneven footing.

The forest features a blend of younger eastern hemlock and older white pines, with some hardwood trees surpassing 200 years in age. This age diversity demonstrates different stages of forest development within a single woodland.
