Mr. Charles Shier:

They have but they are quite preliminary and we are still measuring the greenhouse gas fluxes associated with the different habitat types. We have done a lot of work on individual vegetation types, and what is positive and what negative, but we will now move to measuring greenhouse gas fluxes on a wider footprint, using towers to give us an indication of what a habitat will do. That varies from year to year, depending on the climate, but if one raises water tables and makes an area wetter it will, in principle, reduce carbon emissions. We might not get all the way to creating a sink but the source is less worse, so to speak.
