Why do Tree Branches Fail?

We will explore how researchers from ecology, forestry and arboriculture have utilized biomechanics to understand how trees contend with the forces mother nature can throw at them during their long-life span. Biomechanics approaches integrate biology and engineering principles to explore how organisms deal with their environment. We will explore two studies that examine how loads move through a branch union/fork. A close relationship was found between aspect ratio and different failure types, and we will discuss how this information can help define the point at which a weaker co-dominant fork occurs.
