Swift Valley Country Park adjacent to Old Brownsover is a 59 acre (24 hectare) site managed by the Warwickshire Wildlife Trust on behalf of Rugby Borough Council, set to the north of Rugby’s urban area.
The reserve includes lowland neutral grassland with pronounced ridge and furrow, hedgerows, woodland and wetland adjacent to River Swift and a disused canal.
A very dense bird population exists especially around the pools. Birds include lapwing, snipe and song thrush. Dragonflies and damselflies are abundant and in 2004 the small red-eyed damselfly was recorded here for the first time in Warwickshire. The first moth recording night produced over 60 species along with a healthy bat population.
