The most interesting micro environment is the gravel pit which has thin, very poor soil, rather than the hill itself. Presumably the gravel is a glacial, carse deposit. The flora will inevitably be more dynamic here than elsewhere as pioneer species come in and are themselves superceded in the struggle for scarce water and nutrients. For this reason two permanent quadrats have been established to observe this species flow.
The updated species list is in the associated Picasa album along with a few additional photos. Two of the photos are of a phylloid infloresence of Trifolium repens (White Clover) found on a roadside verge. The petals (standard, wings and keel) could be made out in the ‘florets’. The anthers and female parts needed more imagination.
