Invasive wild pigs (Sus scrofa) as a human-mediated source of soil carbon emissions: uncertainties and future directions.

Invasive wild pigs (Sus scrofa) - also known as feral pigs, feral swine, and wild hogs - have been spread by humans outside of their native range and are now established on every continent except Antarctica (Barrios-Garcia & Ballari, 2012). Through their uprooting of soil, they are known to affect food security, drive the loss of native plants and animals, and jeopardise cultural resources (Barrios-Garcia & Ballari, 2012; Risch et al., 2021; Sloane et al., 2021). In our recent article, we explored another threat from their soil disturbance: greenhouse gas emissions (O'Bryan et al., 2021). We discussed that ongoing and future management of wild pigs could bring potential co-benefits through the reduction CO2 emissions, but our analysis revealed a great deal of uncertainty that points to potential wide-ranging consequences of their management on CO2 emissions.
