Columbia Wetlands Stewardship PartnersColumbia Headwaters Invasive Plant Species Project

The Columbia Headwaters Invasive Plant Species Project (CHIPSP) was successfully implemented in 2008 and has been operating as an effective inventory and management project for the Columbia Wetlands ecosystem and the surrounding area.   This program was required because previous to this study, no baseline data existed for invasive plant species in the Columbia Wetlands.  In addition, in a 2007 report conducted by Canadian Wildlife Service, it was determined that of the two possible ecosystem level threats to the Columbia Wetlands, invasive species are by far the most likely to exist and pose the greatest potential negative consequences.

Terrestrial Surveys

In 2010, Wildsight continued to monitor the terrestrial invasive plant infestations that were hand-pulled in both 2008 and 2009; Spotted Knapweed, Orange Hawkweed, Burdock, Blueweed, Diffuse Knapweed, Yellow Toadflax, Lamb’s Quarters, Bladder Campion, Common Tansy, Curled Dock, Chicory and Hounds Tongue.  Sow thistle is very common and not considered during this project.  Further hand pulling and monitoring at multiple sites was required and completed during the 2010 field season. Please see Table 1.  Program manager Rachel Darvill completed all hand pulling of weeds, along with project field assistant Amanda Gerrard.  On occasion we also had volunteers help us with the pulls. Some species are a low priority since they are not on the Columbia Shuswap Regional District (CSRD) Noxious weed list, even though they are an invasive plant.  Time constraints were also a factor in downgrades for priority. For a more detailed look at what was species were found, where they were found, how they were treated in 2010 and how effective treatments were over a 1 year period, please see the Table 1 at the end of this report.  This table also lists the areas and species of high priority for 2011.
