Frank E. Jadwin State Forest
State Reforestation Areas Lewis #1, #4, #10, and #13
This 20,412 acre state forest, one of the largest and most diverse in New York State, spans the townships of Croghan and Diana. It was named as a memorial to former Conservation Department (now NYSDEC) District Forester Frank E. Jadwin, who was locally instrumental in the acquisition and establishment of the state forests which exist today. A memorial site and plaque was established after his death and can be found on the west side of State Route 812.
The diversity of this forest is evidenced by over 12,000 acres of natural hardwood and conifer forest, 5,000 acres of softwood plantations, 2,500 acres of ponds and wetlands, and 500 acres of brush land, historic sites, and other unique areas. Unusually large and ecologically important wetlands such as Sunday, Patchin, Pine Creek, and Compo swamps drain into trout streams including the West Branch of the Oswegatchie River, Pine Creek, Blanchard Creek, Brown Creek, and Compo Creek.
Over 18 miles of major graveled forest access roads service this forest; including the Wahalula (0.8 miles), Old Croghan 0.7 miles), Judy Cole (2.8 miles), Patchin (1.7 miles), Blanchard Creek (2.7 miles), Loop (3.2 miles), Mountain Swamp (0.3 miles), Nelson(0.8 miles), Henry (0.9 miles), Wisner (2.7 miles), Oswegatchie Corners (0.3miles), Q (1.5 miles), and Bailey Swamp (0.1 miles). Lum (0.2 miles) and PASNY (0.8 miles) are hiking trails and also allow motor vehicle access for people with disabilities by permit. Seven gravel pits exist on the forest and are used to help maintain these routes.
