We conducted a global meta-analysis of vegetation studies and found that the relative importance of different environmental factors as determinants of plant community composition varied with spatial scale. In particular, the importance of climate factors relative to edaphic factors increased with increasing spatial extent and grain, with scale thresholds of about 2000 km2 for extent and 300 m2 for grain.
