About Us
The Okanagan and Similkameen Invasive Species Society (OASISS) is a non-profit organization dedicated to the prevention, detection and management of invasive species in the Okanagan-Similkameen region. Established in 1996, OASISS addresses invasive species and their pathways of spread. Partners work collaboratively to prioritize species and management areas.
The role of OASISS is to encourage and facilitate coordinated inventory, treatment and monitoring of invasive plants. The society is also responsible for monitoring local lakes for invasive mussels and other aquatic invasive species. Public education programming and training is provided via websites, social media and in person throughout the region.
