Staff member responsible for SSSI unit: Paul Hackman
Unit ID: 1016005
Unit area: 9 hectares
Main habitat: Calcareous grassland - lowland
Condition:   Favourable
Latest assessment date: 24 June 2011
Condition assessment comment: The unit was assessed for calcareous grassland (CG3-5), which is the notified feature, but with consideration also given to the broad range of butterfly species found on site. The HLS indicators of success have also been integrated. The herb ratio (59%) and the positive indicators (14 Freq, 1 Occasional and 3 Rare) were both higher than the last assessment and all other attributes, scrub in grassland (rare), negative indicators (none), sward height (7 cm), litter (13%) and bare ground (5%) were all also favourable. The key food plants for the butterflies; kidney vetch (frequent) for small blue, horseshoe vetch (frequent) for chalk-hill/adonis blue and cowslip (rare) for Duke of Burgundy were all found. Although cowslips were only recorded as rare at the stops, they were present in higher numbers at the very top and bottom of the site (probably where the soils are thicker). Increased levels of scrub at the bottom of the slope is acceptable as this is the most suitable area for Duke of Burgundy. However, further scrub clearance under the HLS scheme, is required on the upper slopes to prevent shading of the open grassland and to aid the movement of cattle around the site. It should be noted that the Duke of Burgundy has not been recorded on the site for some years but that management for the species should continue so that conditions are suitable should it return.
