Salmonsbury Meadows (grid reference SP178213) is an 18-hectare (44-acre) biological and geological Site of Special Scientific Interest in Gloucestershire, notified in 1985.

[3] The site is owned and managed by the Gloucestershire Wildlife Trust, and is part of its Greystones Farm nature reserve (grid reference SP173209).

This final acquisition included Salmonsbury Camp (ramparts are visible), which is a Scheduled Ancient Monument.

[5] There is fuller history of Greystones Farm, its meadows and Salmonsbury Camp in a publication produced by the Gloucestershire Wildlife Trust.

They support great burnet, cuckoo flower, quaking grass, ragged robin, pepper saxifrage and meadow rue.

The remainder of the farm is mainly improved grassland, but there are dense headerows which provide good habitat for a wide range of species.
