The risk of visitors spreading the disease is very small and Forestry Commission are not closing forests or advising owners of infected sites to do so. Forestry Commission advice says that spores are produced from infected dead leaves between June and September, spores are unlikely to survive for more than a few days and trees need a high dose of spores to become infected. The Commission also states that there is a low probability of dispersal of the spores on clothing, animals or birds.The Forestry Commission has asked people to take the following precautions if they are visiting an infected or suspected wood:

  • Do not remove any plant material (firewood, sticks, leaves or cuttings) from the woodland
  • Where possible, before leaving the woodland, clean soil mud and leaves from footwear, bicycle wheels and tyres
  • Before visiting other countryside sites, garden centres and nurseries thoroughly wash footwear, bicycle wheel and tyres
