Hello community,
In this video, ISA Certified Arborist Josh Friar evaluates Hypoxylon canker development on a Shumard red oak (Quercus shumardii) in Weatherford, Texas, and explains what trunk colonization actually means from a tree biology and risk perspective. This discussion addresses the stress-induced nature of Hypoxylon (Biscogniauxia species) and why visible bark sloughing and charcoal-like fungal tissue are typically indicators of prolonged physiological stress rather than the original cause of decline.
