RARE PLANTS OF THE SOUTHERN INTERIOR
The Okanagan and Similkameen valleys are home to one of the most unique, endangered and biodiverse ecosystems in Canada. Biodiversity is the variety of life and loss of biodiversity can have lasting effects including fewer new medicines, greater vulnerability to natural disasters and greater effects from climate change. Rare plants have become threatened or endangered in most cases due to urban development and agricultural land use.
