The dataset contains maps of total % C₃ and C₄ plant cover, proportional C₃ and C₄ vegetation (relative to combined C₃ and C₄ cover), and vegetation δ¹³C isoscape (stable carbon isotope values) across Australia. Data are centered on year 2015. We used vegetation and land-use rasters to categorize grid-cells (100 m²) into woody (C₃), native herbaceous (C₃ and C₄), and herbaceous cropland (C₃ and C₄) cover. TERN Ecosystem Surveillance field surveys and environmental factors were regressed to predict native C₄ herbaceous cover. These layers were combined and a δ¹³C mixing model was used to calculate site-averaged δ¹³C values.
