The NWIPC operates throughout a large area of B.C. from the Rocky Mountains of Valemount west 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). In addition to Provincial Crown Land, Nisga'a Nation and First Nations traditional territory, it includes four regional districts; one unincorporated region; sixteen incorporated municipalities; and over 100 Parks/Protected areas; including areas managed by forest licensees, agriculture operations, railways, and the Province via the Ministry of Transporation, and Ministry of Forests, Lands and Natural Resource Operations.
To manage this area, the NWIPC has divided the area into eight 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:
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.
