Invasive Beavers: Bad for the Climate
May 1, 2019
Each year, Wildlife Conservation Society scientists publish more than 300 peer-reviewed studies and papers. “WCS 3-Sentence Science” is a regular tip-sheet — in bite sized helpings — of some of this published work.
Here we present Alejandro Kusch’s work on the effects of invasive beavers on terrestrial carbon storage :
- Scientists documented the effects of invasive North American beavers (Castor canadensis) on carbon sequestration of a riparian forest in Tierra del Fuego.
- Scientists estimated that 1.177 (+/- 0.103) megatonnes of carbon would be lost if all of the predicted 18,384 hectares (70 square miles) of habitat (14 percent of the total forested area) were colonized by beavers.
- These results document the impacts of invasive mammals on large terrestrial carbon sinks and highlight the need for understanding the magnitude of such effects across both landscape- and regional-scales.
