Marine and Coastal Access Bill [HL]

I seek clarification. I was very grateful for the dates that the Minister gave. He said that the initial assessment will be completed by 2012. Is there assessment knowledge now covering the whole of the area, or will it have to be worked on in the years up to 2012? I am not certain what evidence we have now, and how big a task this will be. I presume that the evidence will have to be updated by 2012. If he has any further information on that, it would be helpful.
