This report examined the geographical distribution of critical loads exceedence to English Nature’s natural areas resulting from deposition of sulphur and nitrogen. The results showed that what were sulphur deposition caused a number of natural areas to be at high risk, especially in the English uplands. However, future deposition indicated that this problem will be much reduced, although a number of areas do remain at risk. However, exceedence of nitrogen critical loads is a severe problem for many upland and lowland natural areas. The results were discussed in the context of possible future controls on pollutant emissions and indicated that significant additional control measures would need to be implemented in order to protect many of England’s natural areas.
