Corn Creek wetlands in the Creston Valley


An ecosystem is an ever changing, interdependent system of plants, animals, microorganisms, and "non-living" things—like sand and rock—which come together as a functional unit. Ecosystems can be thought of in wide-ranging scales, from a bug under a decaying log to an entire forest type covering thousands of square kilometres. Because of the topography, latitude, coastline and various climates in the province, B.C. is home to a wide array of ecosystems.

The Columbia River Basin, although not including a coastline, is home to many B.C. ecosystems. For the purposes of the Biodiversity Atlas at this time, we have focused on three basic categories within the Basin. They are: Deciduous Forests, Grasslands and Wetlands. By using the Atlas, you are able to see the many pieces (either together or discretely) which come together to form some of the ecosystems in the Basin.

When our complex ecosystems become simplified through the loss of component parts or processes, they get out of balance and lose their ability to withstand and adapt to natural or human-caused disturbances. Projects like the Biodiversity Atlas enable interested people to observe this balance and, hopefully, keep it in check.
