As of 2022, sixteen formal Partner groups have pledged their voluntary participation in WHIP, including governmental agencies, civic groups, tribal entities, and environmental schools. Recognizing the importance of cooperation and the awareness that invasive species must be managed across jurisdictional borders, these Partners have signed a Memorandum of Understanding (MOU) to show their support for our shared mission. The MOU is renewed every 5 years. WHIP also collaborates with many informal partners including educators, volunteers, and other interested groups.
MOU partners are listed below.
