Who are the IPMTs?

One of the many ways the National Park Service (NPS) is combating invasive plants is through the Invasive Plant Management Team (IPMT) program, whose work provides support to approximately 290 national park units. For the past 22 years, teams have provided professional assistance directly to the parks, filling a much-needed gap in park expertise and assisting parks in preventing introductions of new species, reducing existing infestations, and restoring native plant communities and ecosystem functions.

The Biological Resources Division supports 15 IPMTs from coast to coast. Two more teams are funded through park base funding. IPMT liasons (team coordinators), IPMT data managers, IPMT field crew leaders, and IPMT field staff provide specialized scientific and technical assistance to and across all organizational levels of the NPS.

What do the IPMTs do?

Using multiple strategies, each team creates a work plan tailored to the needs of their partner parks, which may include:

  • Cooperation and collaboration,
  • Inventory and monitoring,
  • Prevention,
  • Early Detection and rapid response (EDRR)
  • Treatment and control, and
  • Restoration.

IPMTs work in a wide variety of ecosystems to target over 700 invasive plant species nationwide. The IPMT’s work in both urban and natural environments, ranging from park units within Washington DC to the Alaskan backcountry.

IPMTs By Region
