The Pennsylvania Army National Guard's (PAARNG) most important training site is also the site of one of Pennsylvania's most important ecosystems. Fort Indiantown Gap National Guard Training Center sits on 5,500 acres of grassland and scrubland habitat, 112 miles of streams, 294 acres of jurisdictional wetlands, and 11,000 acres of forest.

Home to PAARNG headquarters and host to more than 130,000 military personnel each year, Fort Indiantown Gap is one of the busiest Guard training sites in the nation. It also is the only live fire, maneuver military training facility in Pennsylvania as well as serving as a critical habitat to numerous plants and wildlife. At least 127 rare species live at Fort Indiantown Gap, proving a unique management challenge for the installation's Natural Resources Conservation (NRC) team.
