Old forest remnants contribute to sustaining biodiversity: The case of the Albert River valley
The Albert River valley hosts the only old-growth stands of western redcedar in the Invermere Timber Supply Area (TSA). This portion of the Interior Cedar Hemlock moist cool (ICHmk1) biogeoclimatic variant is spatially disjunct from the rest of the ICHmk1 in British Columbia and lies on calcareous s...

The Albert River valley hosts the only old-growth stands of western redcedar in the Invermere Timber Supply Area (TSA). This portion of the Interior Cedar Hemlock moist cool (ICHmk1) biogeoclimatic variant is spatially disjunct from the rest of the ICHmk1 in British Columbia and lies on calcareous soil. Surveys of lichens and vascular plants in the valley bottom of the Albert River revealed an uncommonly rich area, including about 10% of the vascular plant species known to British Columbia. Eight of these are either Blue- or Red-listed in the province. Nine of the lichens found are either new to North America, western North America, or British Columbia, and seven may be new to science.
