The program

Local help, close to home.

The Okanagan Valley is well-known for its diverse habitats, from the lakes, streams and sage-covered grasslands in the valley bottom to the Ponderosa Pine and Douglas fir forests reaching up to the rugged cliffs above. Is it any surprise that the Okanagan Valley has more species of bats living here than anywhere else in Canada?

Bats commonly seen at night and found roosting in and around buildings are the Little Brown Bat and Yuma Bat, although other species can be encountered. The Okanagan and Similkameen region is also home to many unique bats that are at risk due to loss of habitat and a lack of suitable spots for winter hibernation and summer maternity colonies.
