Alan Seeger Natural Area in Huntingdon County, Pennsylvania
A healthy eastern hemlock tree is seen at Alan Seeger Natural Area in Huntingdon County, Pa., on Oct. 7, 2020. An invasive insect, the hemlock woolly adelgid, has attacked trees in the area, which holds a rare stand of old-growth hemlocks. The hemlock woolly adelgid causes an infested tree to drop its needles, and stressed trees can eventually die from heat and drought. Active management in Pennsylvania includes chemical treatment and biocontrols—essentially predatory beetles that eat the invasive insect. Keeping a forest healthy—by safeguarding its soils, water quality and biodiversity—plays a huge part in keeping trees resilient to the invaders. (Photo by Will Parson/Cheapeake Bay Program)
