What characterizes included bark?

What characterizes included bark?

• A. Bark that is strong and supportive for limbs.
• B. Bark that has little connective strength and often fails in narrow crotched trees.
• C. Bark that protects trees from weather extremes.
• D. Bark that enhances the growth of neighboring branches.

Answer: (B)

Included bark is characterized by its lack of connective strength, which poses a risk for the structural integrity of the tree. This condition often occurs at narrow crotches—where two branches or a branch and the trunk meet—leading to a situation where the bark is trapped between the two tissues instead of being properly integrated with the wood. This inclusion can prevent the formation of strong, supportive tissue that is necessary for the branch or limb to withstand stress, such as wind or weight from foliage. As a result, trees with included bark can be more prone to limb failure, especially in adverse conditions. Understanding included bark is crucial for maintaining tree health and ensuring proper structural support in landscape settings.
