Recorders Ian Popely, Graham Oliver and Paul Cogan Walk time= 40mins
At the entrance to the Dalby Forest scenic drive just outside Thornton le Dale this site is a dry unimproved limestone grassland on the tabular hills. The path follows an ancient earthwork and ditch from Ellerburn Bank to the Dalby Forest drive Car Park along the top ridge of the eastern side of Thornton Dale. It was largely native mature mixed woodland replanted with pine planataions and now being restored , it slopes steeply to the east . The route follows various scallops cut into the forest and the ditch in places. Duke of Burgundy has been seen in the ditch and the Marsh thistles and Bugle are favourites with our other Fritillary species.
A poor year compared to recently particularly amongst our grassland species with Wall brown not appearing, Skippers apear to be in a steady decline. teh migrant Vannesids were wel down as they were on many sites along with large whites but unusually Peacocks had a poor year as well. Fritillaries werea littel down while Dingy skipper looks fairly steady. Duke of Burgundy was not seen. See comaprisons below:
Teh following adjustments were applied to compensate for missing beginning of the season: Dingy +5, Large White +1, GVW +7, Brown Argus +1, Red Admiral+2, Small Pearl +2, DGF +5, Peacock +5, Small Tort +1
