There are number of key species found within the Yorkshire Dales National Park. The key species are the northern brown argus that are found in areas of species rich limestone grassland, with a small number of mires still supporting populations of small pearl-bordered fritillary. The small heath is fortunately still widespread in many areas of unimproved grassland.
