The data set contains information on leaf <sup>13</sup>C isotope composition studied on three species, <i>Maireana sedifolia</i>, <i>Ptilotus obovatus</i> and <i>Eremophila scoparia</i> from the core 1 ha Salmon Gum plot at the Credo, Great Western Woodland site.

The dataset contains maps of total % C<sub>3</sub> and C<sub>4</sub> plant cover, proportional C<sub>3</sub> and C<sub>4</sub> vegetation (relative to combined C<sub>3</sub> and C<sub>4</sub> cover), and vegetation δ<sup>13</sup>C 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 m<sup>2</sup>) into woody (C<sub>3</sub>), native herbaceous (C<sub>3</sub> and C<sub>4</sub>), and herbaceous cropland (C<sub>3</sub> and C<sub>4</sub>) cover. TERN Ecosystem Surveillance field surveys and environmental factors were regressed to predict native C<sub>4</sub> herbaceous cover. These layers were combined and a δ<sup>13</sup>C mixing model was used to calculate site-averaged δ<sup>13</sup>C values.

The record contains information on the leaf level physiology, chemistry and structural traits data measured from dominant tree and shrub species from the Great Western Woodlands Site in 2013. Data on leaf level physiology parameters associated with light saturated photosynthesis and intercellular carbon dioxide curves (AC<sub>i</sub>), and leaf dry mass per leaf area trait (LMA) and leaf nitrogen and phosphorous content are provided.
