SKOWHEGAN — Plans to promote and develop a multi-use trail system are underway, with grant money to start on the project at Coburn Woods, a 336-acre nature conservancy owned by the Somerset Woods Trustees. The Somerset Woods Trustees, a land trust that works to promote conservation of forests, wildlife habitats and wetlands in Somerset County, plans to put in two new parking areas at entrances to the woods and eventually expand a three-mile trail system in hopes of getting more people to use the trails, said Roger Poulin, a member of the board of directors. “We don’t have brochures and we’re not really on any websites, so except for people that live in the area no one knows about the trails or uses them,” Poulin said on a recent afternoon as he walked through the trails now covered in leaves. The land trust recently received a $1,500 grant from Plum Creek Timber Company to construct parking lots at two entrances to the trails, on Russell Road and Coburn Avenue.
