Welcome to the Okanagan and Similkameen Invasive Species Society
Celebrating 29 Years
"The Okanagan and Similkameen, a region defined by its exceptional biodiversity, is increasingly facing threats from invasive species – the 'fourth horseman' of global biodiversity loss. Effective prevention and management of invasives is not just an ecological imperative; it's vital for safeguarding our economic prosperity, and ensuring the continued well-being of our community."
- Gregg Howald, OASISS Chair
​
"Globally, invasive species are the second largest threat to biodiversity after habitat loss. Our work is more important now than ever. We are ready to work with everyone, across jurisdictions, to protect natural ecosystems in the Okanagan-Similkameen for the benefit of generations to come."
- Lisa Scott, Executive Director
