Oak Processionary Moth

Lord Clark of Windermere Excerpts

Wednesday 27th April 2011 Lords Chamber

[Lord Henley]

My Lords, I am grateful to my noble friend for all she has said. She is quite right in, first, underlining the public health issues and, secondly, underlining the fact that some oak woodland areas might have to be removed from public access, as has happened in other parts of the EU, although we hope that it will not happen here.

The reason we have moved from eradication to containment is based on scientific advice that eradication within the five boroughs in south-west London that the noble Baroness is aware of is not possible. We managed to eradicate the outbreaks in Leeds and Sheffield but we got on to those much earlier. We did not get on to this outbreak, which started in the summer of 2006, early enough and therefore it will be very difficult to get rid of it. However, we are very grateful for all the work being done by Forest Research, Fera and by Kew Gardens, which also has an interest as it is right in the middle of the area.

[Lord Clark of Windermere]

My Lords, will the Minister confirm that this moth affects other trees as well as oak? In view of the fact that Defra has required the Forestry Commission and Forest Research to reduce their budgets by 25 per cent, with a similar reduction in their staff, is the noble Lord absolutely confident that we have the resources available to tackle this tree-related disease plus the many others that are coming in from overseas at this time?

[Lord Henley]

My Lords, the first point to make is that we do not know that this disease has come from overseas; we do not know where it has come from. Secondly, my advice is that it affects oaks, but I will write to the noble Lord if it affects other trees as well. Thirdly, there is no question of budgetary constraints affecting the fight against this particular menace. I have spoken to the Forestry Commission today and it was perfectly happy to assure me that they had all the resources it needed to fight the problems of the processionary moth. The simple problem is that there are an awful lot of them in a confined area and there are an awful lot of oaks around, and finding all the eggs, larvae and so on is very difficult indeed. Money is not in question.
