Invasive Species


Gypsy Moths have been destroying Pennsylvania’s forests since the 1970s. According to DCNR, the gypsy moth is the principal agent of tree mortality over the last 50 years.

Spotted Lanternfly (SLF) has been reported in Blair County and is abundant in surrounding counties. SLF are commonly found on the invasive tree-of-heaven, but it will lay eggs on any flat surface. While tree-of-heaven is the favorite food of SLF, they also feed on grapevines, maples, hops, black walnut, and other important plants in Pennsylvania. Damage from feeding SLF leads to decreased plant health and/or death. Here’s some tips for identifying SLF:

  • Adults about 1 inch long, spotted wings with red underneath
  • Nymphs are black with white spots
  • Egg masses are about one inch long and have a mud-like covering


Hemlock Woolly Adelgid (HWA) only affects Eastern Hemlocks. They feed at the base of the hemlock needles causing the needles to die. A hemlock can die in as little as four years after being infected by HWA. Tips to identify HWA infections include:

  • White, woolly bunches at the base of hemlock needles
  • Yellowing needles, crown thinning, and branch die back

Japanese knotweed was introduced to the US in the late 1800s as an ornamental and to stabilize stream banks. It covers banks along streams and rivers in the County and along roadsides. Here’s some tips to help you identify it:

  • Large, bright green and heart-shaped leaves
  • Green and red hollow stems resemble bamboo
  • Flowers (white clusters) appear in late summer
  • Commonly found in wetlands or along stream/river banks

Knotweed spreads very rapidly and grows tall and thick, smothering out native vegetation. Though it was planted for stream bank stabilization, it provides very poor erosion control compared to native plants.
