The maps below show the Average Accumulated Exceedance (AAE) of acidity critical loads, and of nutrient nitrogen critical loads, for all habitats combined, and based on UK 5x5 km deposition data averaged for 2013-2015. . Although the legends for the two maps are given in different units, the class intervals are equivalent (ie, 7 kg N ha-1 year-1 is equivalent to 0.5 keq ha-1 year-1).
