Each map contains different sets of geographic information. The list of maps will change over time as more information becomes available. All of the maps (except the 'Agri-environment delivery on SSSIs' map) share the same set of backdrop map layers which are supplied by Ordnance Survey. These backdrop layers will provide you with much of the information you need to understand the area that you are looking at, at any scale.
Natural England manages and maintains all the data relating to wildlife sites and habitats in these maps. In some cases we do this in partnership with other organisations.
