Situated on a high plateau of chalk grassland, Fyfield Down is a NNR and SSSI and displays the best collection of sarsen stones in Britain, which are boulders of siliceous sandstone that were transported to the area through glacial action during the ice age. The two open access broadleaved woodlands are situated within this, Totterdown the most northerly is open in full not a portion as shown on the map (right). The southern wood is unnamed but appears to be used for pheasant breeding.
