Galway’s Atlantic weather puts trees under a lot of stress, and a tree that looks fine in summer can fail in a winter storm. The good news is that most trees give warning signs before they become dangerous. Here’s what to look out for.
1. A new or increasing lean
Many trees grow with a natural lean. What matters is a lean that has appeared suddenly or is getting worse — especially if the soil on the opposite side is cracked or lifting.
2. Cracks and splits
Deep vertical cracks in the trunk, or splits where two main stems meet (particularly a tight “V” union), are weak points that can fail under load.
3. Dead or hanging branches
Dead limbs are brittle and can drop without warning. Branches that have broken but are still hanging in the crown — sometimes called “hangers” — are a serious risk and should be dealt with promptly.
4. Fungus and decay
Mushrooms or bracket fungi growing on the trunk or around the base can indicate internal decay. Soft, crumbly wood and cavities are other signs.
5. Ash dieback
Ash dieback is widespread in Ireland. Affected ash trees lose leaves from the top of the crown, develop dark lesions on the bark and become increasingly brittle. Ash trees near houses, roads and paths should be checked.
6. Root damage
Recent digging, trenching or building work near a tree can damage its roots and affect its stability, sometimes years later.
What to do next
- Keep people and vehicles away from anything that looks like it could fall.
- Don’t climb the tree or try to remove large limbs yourself.
- If the tree is near power lines, contact ESB Networks.
- Book a free assessment — or phone us if it’s urgent.
