It is south of Cheltenham and near the communities of Leckhampton and Charlton Kings, and has a north-facing aspect. The site also includes disused quarry faces, and quarry spoil which has been vegetated.[1] GeologyThe Leckhampton quarries expose the thickest single cross-section through the Middle Jurassic, Inferior Oolite strata of the area. They are a major research interest, and there are many published accounts of the last 150 years. Strata of some 60 m are exposed, and the large outcrops are of significant importance to those studying palaeontology or sedimentology, and for studying ancient environments generally.[1] BiologyThe site supports a range of habitats which include unimproved calcareous grassland, woodland and scrub, cliff faces and scree slopes. The grassland is of major importance and it comprises a tall ungrazed sward. This is dominated by tor-grass, upright brome, meadow oat-grass, sweet vernal-grass and quaking grass. It is noted for its range of herbs which include salad burnet, common rock-rose, common bird's-foot-trefoil. The quarry floors support wild thyme, dwarf thistle, yellow-wort and autumn gentian. The site supports many plants which are scarce at a national or county level. These include fly orchid, musk orchid and purple milk-vetch. It is one of a small number of sites which support meadow clary in the county.[1] Shrub areas support nesting birds such as meadow pipit and grasshopper warbler. It is a shelter area for invertebrates and small mammals.[1] There are wooded areas of broad-leaved and coniferous trees including mature beech. These areas support a woodland flora such as ivy broomrape, white helleborine and greater butterfly-orchid.[1] There is a reported population of the adder.[1] References1. ^1 2 3 4 5 6 Natural England SSSI information on the citation 2. ^Tewkesbury Borough Local Plan to 2011, adopted March 2006, Appendix 3 'Nature Conservation', Sites of Special Scientific Interest 3. ^Natural England SSSI information on the Leckhampton Hill And Charlton Kings Common units 4. ^Cotswold District Local Plan, Appendix 2, Key Wildlife Sites {{webarchive|url=https://web.archive.org/web/20131013215021/http://www.localplan.cotswold.gov.uk/localplan/text/texta2.htm |date=2013-10-13 }} SSSI Source
