Key Biodiversity Areas
Canada's critical places for nature
How we work
KBAs are sites that contribute to the persistence of biodiversity nationally and globally. Found across land, freshwater, and marine environments, KBAs support rare and threatened species and ecosystems, as well as key natural processes. They range in size from small patches of habitat to large tracts of land or water.
KBAs are designated based on specific, measurable criteria. The designation does not give the site a particular management prescription or legal status. KBAs may encompass private or public land, sometimes overlapping, partially or entirely, with legally protected sites.
The KBA Program strives to ensure that sites are properly identified, their values are well documented and effectively managed, and that these places are adequately safeguarded and receive appropriate resources.
Where we work
WCS Canada focuses on KBAs across Canada as part of the KBA Canada partnership.
