Audience:  Government and Public

The objectives of this project are to: (1) inventory current levels of hybridization of WCT populations in the Upper Kootenay drainage; (2) compare current levels of WCT x RBT hybridization with levels 10 to 20 years ago; (3) identify pure populations to be conserved for genetic integrity; and (4) evaluate current and future threats to population persistence to inform conservation management of existing populations throughout the ecosystem.
