Pennsylvania Forestry Facts PA’s nearly 17 million acres of forest land provides recreation opportunites, wood products, clean air and water, and is the habitat for many plants and animals National forest planning effort themes: ~conserve working forests ~protect forests from harm ~enhance public benefits from forests
Coniferous Trees Eastern Hemlock Eastern White Pine • Official state tree of PA • Found in cool, moist woods • Population declining rapidly due to Woolly Adelgid • One of the most valued timber trees • Found in moist or dry woods
Coniferous Trees Pitch Pine Eastern Red Cedar • Medium-sized tree commonly found throughout PA in sandy soil • High resin content makes the lumber good for construction and railroad ties • Slow growing, but long lived tree • Wood is used for fence posts and moth-proof chests

Pennsylvania’sForestThreats Discovered in PA in 1932 and is responsible for millions of acres of defoliation yearly. Discovered in Pennsylvania is late 1960’s and is a serious pest of the Eastern Hemlock. This caterpillar is a threat to many forests causing defoliation of hardwood trees. Major outbreaks recorded in PA since mid-1930’s.
