What is bark?
Quick Answer
Bark is the outer protective covering of a tree or woody plant stem. It helps shield the plant from damage, water loss, and disease.
The Full Story
Bark includes all tissues outside the vascular cambium in woody plants. It protects the tree from insects, pathogens, fire, and physical injury, and in many species it also helps reduce water loss. The outer bark can peel, crack, or thicken depending on the species and age of the tree. In some trees, bark patterns are so distinctive that they help with identification.
