Sudden Oak Death

31/10/2002

New legislation is to be introduced from November 1, 2002, following a European Commission decision to extend to all member states a ban on the import of susceptible plants from parts of the USA where 'Sudden Oak Death' is known to occur.

UK actions against the disease, which has resulted in the death of many oaks and other native trees in the USA, are now being extended to the whole of the European Community.

Emergency notification requirements introduced by the Executive in May will be replaced by an extension of the plant passport regime to all rhododendrons, viburnums and to other susceptible species imported from the USA.


Sudden Oak Death in the USA is caused by a microscopic fungus called Phytophthora ramorum. A Forestry Research Agency scientist discovered that the same fungus was damaging rhododendrons and viburnums in Europe.

Scottish Executive Environment and Rural Affairs Department (SEERAD) inspectors began a survey of susceptible plants in 2001. The first UK outbreak was found in April 2002 in England. The first finding in Scotland was recorded in May 2002.

Since then, the organism has been found at 17 horticultural premises in Scotland and 110 in England and Wales. It has also been found on the Channel Isles. However, it has not been found affecting trees.

Scottish and other UK Agricultural Departments introduced emergency legislation in May 2002 following the first UK finding of the fungus. The measures required importers and growers to notify any movements of rhododendron and viburnum and also included a ban on the import of susceptible plants which could carry the organism from areas of the USA where the disease is found.

Other Member States have also reported findings. In the Netherlands there are reports that a fungus, now identified as Phytophthora ramorum, was damaging plants in 1993, although it was not named as a separate organism until 2001. In addition to the trade restrictions the new measure will require all Member States to carry out surveys for the disease in their own countries.

The Forest Research Agency and the Central Science Laboratory are carrying out research into the susceptibility of European tree species and ornamental plants to the disease.
