Wild pigs “carbon hoofprint” causes climate change? You must be kidding.

The black area is the native distribution of wild pigs and the hatched area is where they are an invasive species (the study’s focal area). Pink and non-hatched is where invasive pigs could expand to in future. On the scale low represents <1 individual/km and high represents >11 individuals/km.
Simulations of CO2 emissions from wild pigs. Histograms show annual CO2 emissions in million metric tonnes (MMT; log10 scale) and proportionate increase of soil CO2 emissions as a result of wild pig soil damage in their current non-native distribution, shown on the map.
