| In F08, BC Hydro continued to participate actively in the Canadian Intermountain Joint Venture (CIJV), a multi-faceted partnership of BC-based resource industries, conservation organizations, academia and government agencies. The CIJV was formed to address the challenges of sustaining healthy populations of birds and other wildlife while ensuring the viability of other uses of the landscape. It is designed to increase the effectiveness of existing and new initiatives to address species at risk and stewardship through effective coordination, building on existing regional partnerships and fostering greater cooperation. | |||

Notes:
- Compliance with the federal Species at Risk Act (SARA) is required and there are provincially listed species that are protected under the B.C. Wildlife Act and the Forest and Range Practices Act (Identified Wildlife). This means BC Hydro must comply with these federal and provincial pieces of legislation by avoiding, mitigating and compensating for impacts to listed species and being involved in recovery strategies and action plans as appropriate. Red and Blue Listings is an inventory process used by the B.C. Conservation Data Centre. It does not have any regulatory force. In the interest of reducing its regulatory risk BC Hydro has been proactive in seeking to identify and reduce its impacts on listed species and undertaking a number of stewardship initiatives.
- Federally listed species under SARA are either Endangered (ENd), Threatened (THr) or of Special Concern (SC). We are currently tallying which of these species and populations occur in lands owned or managed by BC Hydro while proceeding with programs to enhance, restore or maintain known endangered or threatened species and their habitats. This listing does not include stewardship initiatives undertaken solely as part of Water Use Planning and other programs.
- Stewardship means preventative, restorative, enhancement or maintenance initiatives over the long-term time scale required to protect and maintain, restore, or enhance populations and their habitats.
- These programs are largely undertaken with partners as part of our Compensation Programs and were funded in full or in part by BC Hydro and are shown in italics.
