How to pack tropical trees

How many cookies fit on a baking sheet? How many oranges fit in a bag? In order to calculate how much carbon a tropical forest can store, scientists working with data from the Smithsonian's ForestGEO network came up with biologically sound explanations behind the simple mathematical rules of thumb that can be used to determine how many trees fit in a tropical forest and how big they get, essential information for calculating the ability of forests to store carbon.
