Dr. Frank O'Mara:

We have the concrete statistics on the length of hedgerows. I do not have an exact timeframe but it will probably be the best part of a year before we have significant information on the carbon stocks in those hedgerows. There are estimates around but we need more accurate estimates of the amount of carbon in the hedges but, more importantly, how much additional carbon we can put into them because that is the really important point. It is great to have a store of carbon but unless we are adding to it, it is not really taking any extra carbon out of the atmosphere.
