Reducing Storm Damage in Urban Forests:A Pruning Guide

Flyer describing how to prune trees for minimal storm damage.

Pruning reduces the risk of storm damage two ways: by reducing drag (wind resistance on the crown) and by lowering the height of the pressure center of the crown.  This flyer describes the results of research done to test the effects of crown reduction, thinning, and raising on 3 species of 3.5 inch caliper trees.    Drag and bending moment was recorded.
