Research into forest wind risk has been carried out in Britain for more than 30 years. ForestGALES draws together the knowledge derived from this work to provide a user friendly decision support tool for forest managers.

ForestGALES calculates:

  • The wind speed that would be expected to damage a stand
  • Current risk of overturning and stem breakage
  • Change in risk over the life of the crop
  • The effect on risk of thinning and creation of brown edges
  • Risk to any number of stands may be calculated simultaneously
