Managing storm damaged trees

What needs to be considered when assessing, harvesting, and replacing woodland that has been damaged by storms?

Published: 22 Feb 2025

Topic: Manage forests

Storm damage can affect your woodland no matter its size or how much experience you have of dealing with windblown trees.

It is recommended all forest owners and managers ensure a windblow contingency plan is prepared in case of such an emergency.

This guide will help woodland owners and forest managers take action after a windblow event.

Tips for clearing and selling storm damaged trees

Know the law - removing windblown trees

In Scotland, you must obtain a felling permission or exemption to remove windblown trees. 

Exempt trees might include trees that are dangerous or pose a risk to infrastructure. If you apply for felling permission, you are usually required to replace the trees you remove. 

You might also need permission from other agencies such as:

  • Local authorities - if there are Tree preservation orders or you need to fell near roads
  • NatureScot - if licenses are needed for work than may disturb wildlife and protected species
  • Historic Environment Scotland - if felling might affect historic sites

More information on felling exemptions

Our exemptions guidance will help you judge if your felling is exempt.

If no exemptions apply, you must apply for felling permission.

Safety measures in storm damaged woodlands

Landowners are responsible for taking reasonable steps to ensure the safety of people on their land, whether they are:

  • working there
  • walking across it 
  • otherwise visiting

Landowners and farmers should engage experienced professionals with the relevant training to assess and clear windthrow. This is true whatever the severity or size of the area involved.  

The Forest Industry Safety Accord (FISA): Managing Health and Safety in Forestry guidance explains the responsibilities of landowners and others involved in forestry operations.

Did you know

Windthrown trees under tension and compression behave very differently to standing trees when cut. The resultant forces can be violent and rapid when released.

Chainsaw operations

Working with chainsaws amongst windblown trees requires a very high level of technical competency. This is held by professionals with the appropriate:

  • training
  • experience 
  • correct clothing and equipment

The Health and Safety Executive website provides forestry specific information on health and safety.

Chainsaw operations should be kept to a minimum. Mechanised harvesting is much safer though still requires competent machine operators. However, it may not be economically viable in the smallest woodlands.   

Assessing damage

The UK Forest Research agency maps major windthrow via satellite observation.

Understanding the extent and distribution of windblow damage is critical to effective management.

You should assess the affected areas from a safe vantage point or consider a drone survey to provide a greater level of accuracy on the scale and location of the impact.  

Deal first with those trees that present the greatest hazard.

A priority will be creating safe access for those clearing trees and repairing and/or securing fences for stock.

Reopening public access for amenity and recreation may be a pressure point, but this cannot be at the expense of safety.


Restocking

There will normally be a condition to replant the woodland area. We recommend you read felling permissions for windblow for further details.

Felling permission for wind blow

The application for permission or license should be accompanied by mapped information on the:

  • location of the area being harvested or cleared
  • type of restocking
  • species of tree to be used for restocking
  • restocking density or the number of trees to be replanted in the felling area

The UK Forest Standard (5th edition) sets out the issues to consider when restocking harvested areas

Grant support is available for areas restocked under a Forest Management Plan.

Available funding and support

The Farm Advisory Service provides some advice on restocking.

Transporting your timber

Regional timber transport groups work closely with local authorities to manage timber traffic on public roads.

Loading timber onto lorries directly from the public road is not advised because it can be dangerous to other road users.

This should only be undertaken as a last resort and you must contact the local authority before starting to see if traffic management and other permissions are needed.

New or improved accesses onto the public road to reach windthrown stands will also require relevant permissions and/or planning consent.

Agreed Routes for timber transport in Scotland

Agreed Route Maps are developed by the timber transport groups at local authority level.

They categorise the roads leading to forests in terms of their capacity to sustain the likely level of timber haulage.

Agreed Routes Maps have been prepared for most of the forested areas of Scotland. You can view maps that show whether a particular road is an agreed route map for timber transport.

Forest management support

You may want to employ a professional forest manager to oversee operations. They can ensure all work is carried out safely and help you to:

  • ensure you've the required licenses and permission
  • secure a market, harvesting contractors and haulage
  • consider whether certification is appropriate to help you access markets
  • plan how you'll restock the harvested area

Additional support

The Institute of Chartered Foresters and the Confederation of Forest Industries (Confor) can direct you to professionals who offer services on:

  • consultancy
  • forest management
  • timber harvesting

Pests and diseases

It's not recommended to leave large areas of windblown or wind-snapped trees untouched for too long. Damaged trees can attract pests and diseases that may spread to nearby healthy woodlands and forests. 

In some cases, if trees contract certain pests or disease, we may need to issue a notice that legally requires you to clear the diseased trees.

Changing land use

Even if trees are dead, you might need our consent to change the land use from forestry to another use. This requirement falls under the Forestry Environment Impact Assessment legislation.
