TABLE 1.

Breakdown of the Tallo database by biome, including number of tree records and species, as well as the median and range of stem diameter (D, in cm), tree height (H, in m) and crown radius (CR, in m) values. Biome classifications follow those of Olson et al. (2001), with boreal and montane biomes grouped together
