How do you apply the appropriate ammonia critical level to a vegetation type. For example, for vegetation types such as peatland and woodland would apply the 1ug it would mainly contain lower plants?
Why are there data missing about Areas/Sites of Special Scientific Interest in some of the critical level/load datasets for download?
Where can I find data about critical loads, levels and background concentration and deposition for UK national (SSSIs) and international protected sites?
