What is bark damage, and what commonly causes it?

Bark damage refers to harm inflicted on the tree's outer layer, known as the cambium layer, which is critical for the tree's health. This layer is responsible for the transport of nutrients and water throughout the tree. When bark is damaged, it can lead to the tree's vulnerability to diseases and pests, ultimately compromising its vitality.

Common causes of bark damage include mechanical injuries from equipment such as lawnmowers, trimmers, or other tools used during maintenance or landscaping activities. Additionally, animals like deer or rodents may also cause bark damage by gnawing on the tree. This damage disrupts the tree's ability to transport essential nutrients, making it a significant concern for overall tree health.

While excessive watering, natural shedding of bark, and inadequate sunlight exposure can affect a tree's health, they do not specifically relate to the definition of bark damage or its primary causes. Thus, understanding that bark damage is directly attributed to physical harm from external sources is crucial for effective tree care and management.
