The nature reserve at Upton Warren, managed by the Worcestershire Wildlife Trust, is situated between Droitwich and Bromsgrove. This popular reserve is divided by the River Salwarpe with the Moors Pool to the north and the Flashes to the south. 

The Moors Pool, being deeper attracts most of the wildfowl, while the surrounding reedbeds are excellent for reed loving species, most notably Cetti's Warbler and during the winter, Bittern. 

The Flashes is one the prime locations in the county for observing a wide variety of waders, particulary during the spring and autumn passage periods. Throughout the reserve there is a mixture of alders, willows and scrub which can be attractive to a variety of passerines throughout the year. In addition, the sailing lake located between the Flashes and the Moors Pool can be productive for passage terns and gulls or maybe a seaduck.
