Why are there multiple critical load graphs for the same interest features at a particular site especially for dune habitats?
There are two sets of values CLmaxS, CLminN and CLmaxN for each SAC or SSSI i.e. minCLmaxN and maxCLmaxN. Which should be used here? Should both sets of values be assessed and, if so, how should the results be reported?
Which acidity critical load values (CLmax S, CLminN, etc) should be used in risk assessment and how can it be reported?
Are freshwater systems (eg flowing water, mesotrophic and eutrophic waters) sensitive to acid and nitrogen deposition?
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?
