Invasive beavers: Bad for the climate

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 (14 percent of the total forested area) were colonized by .

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.
