Within the Ingleborough National Nature Reserve, the transect goes across Scar Close, an area of sparsely wooded limestone pavement supporting a wide diversity of calcareous grassland species. The site is unique in having areas of peat on the pavement that support more acidic tolerant species. The transect was established primarily for Northern Brown Argus but in recent years has had a large colony of Dark-green Fritillary. The discovery of Small Pearl- bordered Fritillary in 2007 highlights the importance of the transect monitoring approach for some of the key butterfly species in the upland

Although the data has too many gaps to have alot of certainity we can see the skippers have gone absent this year along with Orange tips and Peacocks are very much lower. Overal counts compared to the peak in 2019 are about half largely as a result of this and of course the Painted Ladies that year. You can also guess that Dark Green fritillary and the Small Pearls are also holding well.. if not increasing.
