WebIn a study, published in the journal Nature, Thomas Crowther and colleagues (2015) mapped tree density across the world. 3 To do this, they utilised 429,775 ground-sourced measurements of tree density from every continent on Earth to generate a global map of forest trees. They define a tree as a plant with woody stems larger than 10 cm diameter ... WebFor example, citing previous studies, they point out that the mass of leaves on a typical tree can grow 100-fold for a 10-fold increase in tree diameter. At the scale of the tree stand, the authors suggest that decreasing productivity can be explained by the death of trees leading to a decrease in tree density in a given even-aged stand.
