The NWIPC operates throughout a large area of BC: roughly west of the Rocky Mountains to the Pacific Ocean, including the Queen Charlotte Islands, 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 area, the NWIPC has divided the area into seven invasive plant management areas (IPMAs) in order to undertake invasive plant management over geographically defined areas as opposed to a jurisdictional basis. The IPMAs are:
- Queen Charlotte Islands
- Stikine-Skeena
- Houston
- Burns Lake
- Vanderhoof
- Prince George
- Robson Valley
Contractors in each IPMA inventory, treat, and monitor invasive plant infestation sites using the NWIPC Plan and Profile as a science-based strategy and treatment prioritization.
