This week, hundreds of volunteers will plant more than 15,000 trees over 23 acres at the Flight 93 National Memorial. Since the reforestation project began in 2012, more than 2,000 volunteers have planted more than 105 acres with 74,000 trees of many varieties native to the area.
In three to five more years, the goal is to fill the former coal mine with 150,000 indigenous trees, reports Mary Pickels in the Tribune-Review.
Varieties planted this year will include American chestnut, sugar maple, dogwood, red maple, American crab apple, white pine, black walnut, and Pennsylvania’s state tree, the Eastern hemlock.
