Invasive Plant Inventories at Provincial Parks


Kikomun Creek, Norbury Lake, Premier Lake and Wasa Lake are use front country parks found within the Ministry of Environment (MOE) Kootenay Region.  Ecosystems in these parks provide important habitat for a wide array of native plant and animal species, and also contain a number of rare and endangered species.  Invasive plants threaten the integrity of some of these ecosystems.  In response to this threat, the MOE Kootenay Region implemented an Invasive Plant Inventory at these parks.

Inventories were conducted for all invasive plant species identified in the Forest and Range Practices Act, BC Weed Control Act within the four identified parks. 

Results from this invasive plant inventory at Kikomun Creek, Norbury Lake, Premier Lake, and Wasa Lake Provincial Parks can be summarized as follows:

  • Parks ranged in size from Premier Lake at more than 830 ha, to Norbury Lake at 100 ha, with the area surveyed totalling 1760 ha
  • Eighty polygons were surveyed among the four parks ranging from 40 at Kikomun Creek to 9 at Wasa Lake
  • Approximately 320 sites were located during the survey, with nearly 400 invasive plant sites
  • Kikomun Creek accounted for more than one-half of the total sites and total invasive plant species sites
  • Norbury Lake was the smallest of the parks surveyed, but contained more than 30 total sites and 50 individual invasive plant sites
  • Premier Lake is the largest of the parks, but it had the least total invasive plant species sites, and the second lowest number of total sites
  • Wasa Lake was the second smallest park, but had the second largest number of total sites and total invasive species sites, with 68 and 72, respectively
  • Spotted knapweed, houndstongue, Canada thistle, oxeye daisy, sulphur cinquefoil and hawkweed species are the primary species among the four parks
