At Brockwells Meadows the lime-rich soil promotes a wide diversity of grassland flowers.  Over seventy species of plant have been recorded.  The four fields of unimproved grassland are grazed and cut for hay in rotation.  After the hay is cut in late June, cattle are brought onto the fields.  Their cow pats are an important breeding site for several species of rare insects, particularly the hornet robber-fly.

Species

Notable species include green-winged orchid, autumn lady's tresses, large thyme and yellow wort.  Rare insects include the great green bush cricket, the hornet robber-fly and a very rare solitary bee Andrena battorfiana.  Many species of moth and butterfly have been recorded.
