Fig. 3: Relationship of litter mass (XTsf) to Aridity Index (AI) for Australian forests and woodlands.
From: Litter accumulation and fire risks show direct and indirect climate-dependence at continental scale
AI = 1 (vertical dashed gray line) when precipitation and evapotranspiration are equal. Red line is moving average and orange shading represents the 0.999 confidence interval.
