WHIP is a multi-partner co-op consisting of Federal, State, Tribal and County government agencies plus local non-profit organizations and schools specializing in environmental education. These groups work together under a memorandum of understanding which encourages and formalizes the cooperative relationship necessary for effective management, coordination and implementation of invasive species programs. Additional organizations or individuals are encouraged to contact any WHIP steering committee member for information regarding how to informally participate with WHIP.
