The two subcommunities of MG5, characterised by species rich grassland form a belt across the site, but they do not cover the whole site. Towards the north there is a community dominated by False oat-grass ("Arrhenatherum elatius"), a constant species in the MG1 and MG2 communities of the British NVC and therefore not typical of an MG5 community. At Whitton Bridge Pasture it is growing on alluvial soils located at the northern edge of the site, which have most likely been formed by Whitton Beck just to the north. A number of springs at the site are associated with flushes of the Pale sedge ("Carex pallescens"), which form small populations.
