Quick Summary

A "shake" in forestry refers to a separation of wood tissue within timber. These defects can occur in various ways, such as ring shake, heart shake, or wind shake, and are often caused by factors like shrinkage, high winds, or the natural growth processes of the tree. These separations can negatively impact the wood's appearance, strength, and stability. Shingles, a building material used for roofing and siding, can also be made from wood, sometimes split from logs in a manner that relates to the term "shake".123456
