A new map shows forest height around the globe and will improve estimates of how much carbon is stored in trees.

Figure 1: Variation with height in physiological and structural features of redwood trees at Humboldt Redwoods State Park, California. We accessed tree crowns by shooting arrows trailing filament ...

For Sophie’s tree that means 110cm 3.14 = 35cm diameter. To calculate the TPZ, multiply the diameter by 12; for Sophie’s tree that is 35 x 12 = 420cm or 4.2m.

1 A height-light trajectory (HLT, a fitted curve relating canopy exposure to tree height) was determined for populations of individuals of each of 47 tree species in a Liberian lowland rainforest. The ...
