COTTONWOOD RIPARIAN ECOSYSTEMS OF THE SOUTHERN INTERIOR

BC Ministry of Environment's Lands and Parks Division, British Columbia Ecosystems at Risk publication

"Why are cottonwood ecosystems at risk? In British Columbia's dry southern interior, black cottonwood forests are found along the banks of streams and lakes where moisture is plentiful. These islands of green in an otherwise arid environment provide crucial habitat for a wide range of plant and animal species. Even if the adjacent land is not developed, once the flooding disturbance is lost it is only a matter of time before the cottonwoods die off and are replaced by other tree or plant species." "The BC Conservation Data Centre has ranked the cottonwood ecosystems of the southern interior among the rarest plant communities of the province. Already reduced to mere fragments, the remaining stands are considered endangered. In the South Okanagan and Similkameen Valleys, fewer than 500 hectares remain, 411 hectares of which is privately owned land. Undisturbed stands make up only a fraction of this total."

SPECIES AT RISK & LOCAL GOVERNMENT - A PRIMER FOR BRITISH COLUMBIA

[Hosted by the District of Squamish]   British Columbia is home to a wealth of native species and subspecies - more than any other province. They include 1,088 vertebrates, 2,850 vascular plants, 4,500 marine invertebrates and over 35,000 insects. This web site will help you: learn about species at risk and the threats they face, learn which species at risk are in your area, search for species at risk by name or ecosystem type, and learn how Local Governments can help conserve species at risk.
