In this episode of Talking Trees, we pay tribute to Dr. Alex Shigo, the father of modern arboriculture. His groundbreaking research on tree biology, particularly the CODIT model (Compartmentalization of Decay in Trees), revolutionized how arborists understand and care for trees.

We discuss:

• His pioneering work at the U.S. Forest Service
• The shift from wound "healing" to compartmentalization
• How his discoveries redefined pruning practices and tree risk assessment
• His famous motto: “Touch trees.”
• The lasting global influence of his teachings on arboriculture

Dr. Shigo didn’t just change how we cut trees—he changed how we think about them. His legacy continues to guide arborists, urban foresters, and tree lovers worldwide.
