Dr. Alan Moore:

I will start with some of the initial questions and then pass to Ms O'Sullivan and possibly Mr. Hickey. The Senator mentioned the 380,000 km of hedgerows. In fact, we have perhaps double that amount. The estimate from the Environmental Protection Agency, EPA, is that we have up to 700,000 km of hedgerow but many of them are in poor condition. What we do not have is native woodlands. We have about 1.5% of cover for native woodlands. In essence, our hedgerows are our woodland cover. That is why they are relatively more important in this country compared with other countries. We have better hedgerows than, for example, continental Europe, but in comparison with the UK we are not doing so well. In answer to the question about the measurement of scrub and bushes and so on, I will hand over to Ms O'Sullivan. She has the answers on the farm carbon survey.
