The Sea to Sky Invasive Species Council (SSISC) is a non-profit society that works in cooperation with organizations, governments and industry on the south coast of British Columbia, Canada, in a province wide effort to minimize the negative impacts caused by invasive species. The society was formed in July of 2009 and initiated by Stewardship Pemberton and the Whistler Biodiversity Project.

What we do:

  1. Raise awareness and educate the public, government agencies, and other land managers about invasive species and their impacts;
  2. Provide a conduit for information and a source of expertise on invasive species including identification, prevention and control;
  3. Improve invasive plant stakeholder communication and information sharing;
  4. Minimize the further introduction and spread of invasive species in the area through early detection and control, and coordinated integrated invasive species management efforts; and
  5. Work with local government to implement policy.

Where we work:

We work on the southern coast of BC just north of the Vancouver Regional District.  Our borders coincide with the Squamish-Lillooet Regional District (SLRD) electoral areas C & D, which includes Squamish, Whistler and Pemberton.  We also cover the Village of Lions Bay that is just south of the SLRD.


We work closely with our neighbouring invasive groups: the Coastal Invasive Plant CommitteeGreater Vancouver Invasvive Plant Council, Fraser Valley Invasive Plant Council and the new Lillooet Region Invasive Species Society.

We also work closely with the Invasive Species Council of BC and all the regional invasive councils throughout BC.
