Woody encroachment and subsequent brush management aimed at reducing woody plant cover can alter soil organic carbon (SOC) pools. However, brush management influences on the sources and stability of SOC is unknown. Using a space-for-time approach in a site with closely co-located patches representing unencroached grassland, woody encroachment, and brush management, we coupled stable isotopes and plant-derived biomarkers to quantify how woody encroachment alters input sources and stability of SOC and how these patterns change with brush management.
