No threat to global soil carbon stocks by wild boar grubbing.

Abstract

In their paper "Unrecognized threat to global soil carbon by a widespread invasive species" O'Bryan et al. (2021) suggested that wild boar (also named feral pigs or wild pigs) and their grubbing reduce global soil organic carbon (SOC) stocks. In this study models were used to estimate global wild boar abundance and postulated additional CO2 emissions due to wild boar bioturbation. However, the authors ignored experimental evidence about the effects of wild boar on SOC that points in a completely different direction altogether.
