The Northwest Invasive Plant Council (NWIPC) was established to provide resolution of issues and coordination for invasive plant management programs in Northwest BC.
The Northwest Invasive Plant Council (NWIPC) is a not-for-profit organization with a Board of Directors representing a diverse range of stakeholder groups. The NWIPC currently has directors representing the local government, provincial government, First Nations, agriculture industries, environmental groups and utilities.
The NWIPC operates throughout a large area of BC: roughly west of the Rocky Mountains to the Pacific Ocean, including Haida Gwaii, and north of Quesnel to the Yukon border. The area comprises a total land base of 37,642,600 hectares, including 854,013 hectares of Agricultural Land Reserve (ALR). It includes four regional districts; one unincorporated region; sixteen incorporated municipalities; over 100 Parks/Protected areas; First Nations land; land managed by utility companies, forestry operations or the agriculture industry; in addition to crown land.
To manage this large landbase, the NWIPC has divided the area into seven invasive plant management areas (IPMAs). The IPMAs are:
• Haida Gwaii
• Lakes District
• Prince George
• Robson Valley
NWIPC provides support and coordination for those involved in the various aspects of invasive plant management including awareness, inventory, treatments and assessment. NWIPC also uses resources pooled by member organizations to conduct on-the-ground management and treatment of invasive plants.
