About Fraser Valley Invasive Species Society

Protecting Fraser Valley Biodiversity

The Fraser Valley Invasive Species Society is a non-profit society. Our mandate is to minimize the negative social, economic, and environmental impacts associated with invasive species. We achieve our mandate through coordination of land managers, education and outreach, and on the ground invasive plant management. Invasive species are considered to be one of the greatest threats to biodiversity world-wide, second only to habitat loss. Already introduced plant species represent 26% of the entire flora in British Columbia (BC Conservation Data Centre, Ministry of Environment, 2012). All citizens of British Columbia are affected by invasive species. Help preserve our natural heritage!

Priority Ranking of Invasive Plants

The Fraser Valley Invasive Species Society holds regular strategic planning sessions where we update the list of priority species for management that field season and identify high priority areas for invasive plant management. We currently have four categories for invasive plants:

Prevent
Species not known to occur in the region but likely to establish if introduced. Watch for, and if found, eradicate.
Eradicate
Species known to occur in limited distribution and low density. Eradicate if found.
Contain
Established infestations found in portions of the region. Contain existing infestations and prevent spread to uninfested areas.
Control
Established infestations common and widespread throughout the Fraser Valley. Focus control in high value areas and use biological control if available.
