OASISS encompasses the Okanagan-Similkameen, a region known for its high tourism and recreation values, and diverse agriculture. It is a hot spot for species and ecosystems at risk. The dry climate and desert-like habitats – an extension of the Great Basin Desert to the south – are unique in BC. These features combined with an ever-growing population create challenges with respect to the management of invasive species.


Our strategic planning needs to take into consideration all these factors when making decisions about how to best manage the highest priority invaders, such as puncturevine, longspine sandbur and yellow flag iris, species that either occur completely or predominantly within the confines of our region. Part of our success during the past 25 years is a direct result of cooperative and collaborative partnerships with our neighbouring jurisdictions, including our colleagues in Washington state.
