Containment Areas

A containment area identifies a core infestation of invasive plants. Invasive plant control is generally done from the outside (less dense) to the inside (more dense, source population) of the containment area, using multiple control methods (e.g. biocontrol inside the containment area and mechanical and/or chemical control outside the area). A containment area with complete elimination or naturalization (using biocontrol) of the target species can be removed.

The CCCIPC invasive plant containment areas are identified by consensus decisions by the Regional Strategic Planning subcommittee. Once the CCCIPC board of directors has agreed on a containment area and its perimeter is defined, this information is sent to the Inter-Ministry Invasive Species Working Group (IMISWG) for final approval. When approval is obtained, the containment area polygon is sent to the Invasive Alien Plant Program application manager to be included in the database. For more information about establishing containment lines, please refer to the IMISWG Protocol to Establish Containment Lines. There are currently 5 containment areas in the CCCIPC. These containment areas are for dalmatian toadflax, field scabious, marsh plume thistle, orange and invasive yellow hawkweeds and sulphur cinquefoil.  The marsh plume thistle containment line joins up with the containment line just north of the CCCIPC border that the NWIPC has established to delineate the areas of intensive concern and minimize the spread of MPT. There is a knapweed containment line to the south of the CCCIPC’s geographic boundaries on the border of the Thompson-Nicola Regional District.
