My Lords, I endorse everything that the noble Lord, Lord Liddle, said, based on his experience as a member of our committee.
The noble Lord, Lord Randall of Uxbridge, mentioned that, proportionately, more woodlands are affected by this project than in the case of HS2 phase 1. One should not be surprised about that, because it takes a long time to get out of the built-up area around London, and quite a long time before its begins to reach the much more urban countryside through which this phase passes. Therefore it is a feature of this particular phase that we encountered a lot of countryside, a lot of farmland, and indeed woodlands.
The noble Lord was perfectly correct and the statistics are these: 10 areas of woodland are affected, of which about 9.8 hectares will be lost due to the project. Most of them are quite small but there is a particular one, at Whitmore Wood, where a substantial amount will be lost but there is a good deal of replanting and enhancement going on to make up for that.
As far as the issue of net gain is concerned, we discussed that at some length with the Royal Society of Wildlife Trusts. To endorse the point that the noble Lord, Lord Liddle, made about the sensitive way in which HS2 was approaching these issues in our inquiry, we did have quite a lot of discussion about how net loss and net gain could be addressed. It was counsel for HS2 who suggested perhaps a nuanced approach to this issue would be appropriate and, based on what he said, in our report we encouraged HS2 to continue that approach. Shortly afterwards, a written assurance was given to that trust, which the trust has accepted.
One of the problems with going too far with promoting net gain is that before you get very far you find yourself having to acquire more land. That would be acquiring more land from hard-pressed farmers who are already losing a substantial amount of land as a result of the line itself and its associated works. We were very cautious not to be led too far down that path. One has to bear in mind, too, that a community development fund has been set up that would enable other landowners who feel that they can give up part of their land to obtain funding to make up the loss of woodland that is due to the scheme. The noble Lord, Lord Liddle, with great respect, is absolutely right about the sensitive way in which this matter has been dealt with by HS2, so far as we can see in the material that was before us at the inquiry.
There is, however, one matter I would like to express concern about: the woodland indirectly affected. We were not asked to examine any of these, but the kind of effects that are likely happen would include vibration and dust from the movement of a very large number of vehicles over a substantial period. This is something to be careful about, considering the impact on woodlands that have not been taken down but are in the vicinity and where wildlife exists that may be very disturbed by what is going on. There is certainly something to be said for the thinking behind this particular amendment—I am talking about Amendment 9—with regard to the indirect effect on other woodlands in the very attractive area through which this particular line is going to pass.
