Natural Environment and Rural Communities Bill

Will the Minister say in writing—which I think she suggested that she would do—whether there is a methodology for measuring biodiversity used by Defra, if so what it is, and whether we can have a look at it? As my noble friend Lord Dixon-Smith said, biodiversity operates at many different levels—at a national level, in a piece of ground of 1.5 hectares or even in a garden. Without some methodology for measuring what is happening, I am not sure that we shall get very far with biodiversity.
