The environment of Combe Valley is determined by natural annual winter flooding, farming 
 activity and the unfortunate decision to site a major rubbish tip on a flood plain.
 The Valley has two headstreams - the Watermill and Powdermill and these join the central
 Valley river - the Combe Haven (formerly the River Asten).
 Woodland slopes, reed beds, fens, marshes, lakes, pools and water meadows make for a
 wonderful combination of wildlife habitats which are still being explored.
 Winter flooding causes the central Valley to fill for several months, bringing in flocks of
 birds  especially Greylags and Canada Geese, Shoveler ducks and Cormorants.
 Throughout the year, barn owls, buzzards, marsh harriers, red kites, sparrowhawks, kestrels
 and hobbys can be seen hunting.
