THE SCIENTIFIC ANALYSES that have led to the provincial government’s recently announced old-growth logging deferrals were first developed by Dr Karen Price, Dr Rachel Holt and forester Dave Daust. Their 2020 peer-reviewed study, BC’s Old Growth Forest: A Last Stand for Biodiversity, estimated that 33 of BC’s 36 forested biogeoclimatic zone variants have 10 percent or less remaining forest containing large or very large trees.
Because of the physical and biological characteristics of old-growth forests containing large trees, they support high levels of biodiversity. But Price, Holt and Daust have pointed out that when the extent of such old forest in a biogeoclimatic zone variant falls below 10 percent, that zone falls into a high risk category for loss of biodiversity. The result? Most of BC is now teetering on the brink, beyond which extinction of plant and animal species will surely accelerate. (Story here).
The three are also founding members of the Science Alliance for Forestry Transformation (SAFT). SAFT’s public outreach includes video presentations on the subject, including the one below in which Price explains why we need to end logging of old-growth forests containing large and very large old trees.
