This is one of the very few SSSIs in north Bucks, designated for their very rich flora and variety of habitats – some old ridge and furrow, limestone slopes and species-rich wet areas along spring lines. Early spring delights the eye with Cowslips on the ridges and Green-winged orchids on the banks. For the ‘orchidophiles’ there are other species together with many showy flowers as well as several ’greens and browns’ of significance e.g. Adders-tongue fern.
