Storm Damage and Natural Disturbance

Tree downed during storm

Forests are dynamic ecosystems shaped by human and natural disturbances. While we may carefully tend and manage our forests to meet our objectives, a storm, fire, pest infestation or other natural disturbance may change the landscape abruptly and cause us to redirect our management decisions.

When a natural disturbance occurs in our forests, we often need or want to take action.

If you have questions about storm damage on your woodlot, contact your County Forester. Download our staff list with contact information here.

Debris Cleanup

The most important message is trees and forests recover from damage, so don’t panic, be safe and seek professional help.

The best advice is a word of caution: Removing large trees or limbs is dangerous. Don’t climb a ladder with a chain saw. Don’t climb into a damaged tree. Never touch any tree near electrical wires. Assess your particular tree situation carefully and watch for safety hazards. Most tree work needs to be done by professional arborists, especially when the work requires climbing or the tree is leaning against another tree or structure.

Stay safe! Seek professional advice before undertaking the job, and use common sense as you work. A few tips:

  • Don't try to clean up storm-damaged trees during high wind conditions.
  • Stay away from downed or sagging power lines until utility crews have arrived and repaired them.
  • Don't work alone.
  • Wear a hard hat and other recommended safety gear.
  • Watch for hanging limbs and leaning trees.
  • Remember that trees and branches may be unstable and pose considerable risk.
  • Contact your insurance company for instructions, and take pictures to document damage for potential claims.

Assess immediate hazards first: Remove dead trees; trees or branches that are leaning; trees with broken or cracked stems; trees with extensive broken roots; and any large, dead, or broken limbs that are still attached to the tree.

Hire an arborist: For homeowners, hire a qualified arborist to get the work done properly and safely. Trained arborists are aware of proper pruning and removal procedures and can reduce the chance of further damage to the tree. Check to see if they are certified and ask for certificates of insurance, including proof of liability for personal and property damage and worker’s compensation. Also, request local references and get more than one estimate.

Prevent additional damage: Later, you may want to prune the damaged trees to improve appearance and reduce additional hazards. If the top has been broken, the tree should be pruned back to a strong lateral branch. Damaged branches should be pruned back to the branch collar.

Don’t forget to look at your trees in the spring and summer: Some damage may not be immediately apparent. Hidden cracks may cause branches to droop when leaves come out in the spring. Stem decay, as well as cracks, may lead to structural loss, causing the tree or large branches to become hazardous. Root damage may not be evident until twigs or branches in the upper crown begin dying after two or three growing seasons.

Hire a forester: If you own large acreage, contact your County Extension Forester or a licensed forester to assess the damage, then salvage the trees if needed. Over time, damaged trees may develop decay and discoloration. As long as it is safe, there is no need to rush. You have more than a year to act before you lose wood to discoloration and decay.

For additional information and assistance, call your local UNH Cooperative Extension County Forester.
