YWT Ashberry  Pastures transect is set with tall vegetation by the side of a stream fed by calcium rich springs which runs through the reserve. There were many plants typical of limestone marsh and grassland with extensive patches of Marsh Lousewort; Marsh Valerian, Marsh Pennywort and Marsh Bedstraw are also found. abundant  sedges such as Glaucous, Carnation, Hairy and Bottle and at least four species of rush, plus Butterwort along with Bird’s-eye Primroses can be seen

Its butterfly importance is because it is a former Duk of Burgundy site but also has the threatened Wall and Small Heath Butterfly plus occasional Dingy Skipper


The damp areas of section 1 favours the Orange Tip . The first three sections are mostly grassland  favoured by Large and Small Skippers, Dingy Skipper and the Browns.  As you head upwards  entering more dense woodland in Section 4 and 5  opening in section 6   Section 7  yields larger numbers  particularly woodland species including  a single Silver-washed Fritillary in 2020  and Speckled wood but also Wall has been seen. 


2023   No data , 2019-2021  incomplete 

The species profile on the site have changed dramatically over the last few years but data is a liitle sparce to get a complete picture except to say  the skippers have increased dramatically  in the first 3 sections as have the Browns but to a lesser extent
