The Anatomy of a Tree: To fully appreciate the work of arborists in Clackamas County, it’s important to understand the basic anatomy of a tree. Trees are complex living organisms, consisting of several parts that work together to support growth and health. Here’s a breakdown of the key components:

  • Roots: The root system anchors the tree and absorbs water and nutrients from the soil. Healthy roots are crucial for the tree’s overall vitality.
  • Trunk: The trunk supports the tree and acts as a conduit for nutrients and water between the roots and the canopy. It consists of several layers, including the bark, cambium, and xylem.
  • Branches and Twigs: These extend from the trunk and support the leaves, flowers, and fruit. They also play a role in transporting nutrients.
  • Leaves: The leaves are the primary site of photosynthesis, where the tree converts sunlight into energy.
  • Bark: The outermost layer of the trunk, branches, and twigs, the bark protects the tree from physical damage and disease.

How Arborists Use Tree Anatomy to Assess Health: Arborists in Clackamas County and beyond rely on their understanding of tree anatomy to diagnose health issues and recommend appropriate treatments. Here’s how they use their knowledge to assess tree health:

Examining the Root System: Healthy roots are essential for a tree’s stability and nourishment.

Inspecting the Trunk: The trunk is a vital part of the tree, and arborists in Clackamas County closely examine it for signs of decay, cracks, or cavities.

Observing the Leaves: The condition of a tree’s leaves can reveal much about its health.
