Tree Shape and Branch Structure: Mathematical Models

Dick F Yeatts Mathematical and Computational Forestry & Natural-Resource Sciences (MCFNS) 2012

Other claims from this paper (9)

Method / resource A leaf distribution model describes tree profiles with one parameter.
Observation The total area of stems leaving a fork usually exceeds the entering stem area.
Mechanism The model finds that bulking up reduces branching tissue quantity.
Association Branching angle increases with the degree of bulking up.
Association Trunk cross-sectional area is determined by tree profile and side branch angle.
Observation Observed crowns show azimuthal symmetry.
Method / resource Uniform crown leaf distribution produces nearly spherical predicted profiles.
Method / resource Leaves concentrated at branch ends produce essentially conical predicted profiles.
Method / resource Field branching measurements generally agree with the predicted relationship.
