About the Site Relevant Critical Loads Tool

The ‘Site Relevant Critical Loads’ tool provides critical loads for acidity and nitrogen for designated features within every SAC, SPA or A/SSSI in the UK. You can view an overview of each interest feature for each site. Critical loads are assigned to each sensitive feature for either nutrient nitrogen or acidity. Furthermore, deposition data for nitrogen and sulphur at each site are provided, apportioned to major sources, and presented in pie charts. You can also select a grid reference if you know the exact location of your feature within a site. Simply follow the screen below.
