Synopsis

The River Tay and its estuary is one of Britain's largest and most important aquatic systems. Rising at 625 m and flowing for 148 km the River Tay is the largest by flow in Great Britain and has a catchment area of 5031 km2. There are considerable ecological changes from source to estuary. These take the form of transitions, but four main aquatic communities can be recognised: an upper, base-poor, swift-flowing alpine section, then an oligotrophic section with moderate flows at lower altitude, next a much richer, slower flowing, more lowland stretch and finally the upper estuary itself. The problems of classifying and conserving running water systems are discussed and the importance of the Tay system is emphasised. The linear form and catchment size of larger rivers makes it difficult to give them—particularly their lower reaches and estuaries—full conservation protection. The River Tay is sufficiently unique, both physically and biologically, to warrant further scientific investigation and nature conservation protection.
