Sir Julian Lewis: I am grateful to my hon. Friend [Siobhan Baillie], both for initiating this debate and for kindly letting me say a word about the Freshwater Habitats Trust, whose New Forest representative, Thea Margetts, I met at the volunteer fair put on by the national park authority last weekend. It is amazing what these volunteers contribute, not least the New Forest water code and other great pointers and advice as to how we can keep these precious but delicate environments safe.
