| Brief_description |
| An IBA. Open estuary, with sandbanks, tidal mudflats and floodplain; mouth closed during periods of low flow. Some Phragmites, Typha and sedgebeds. Regularly has 10 000+ birds; many migrants; major tern roost on sandbanks, with many Common and Little Terns in summer, the latter increasing in numbers. Winter numbers of Swift Tern increasing and of Spurwinged Goose and Kelp Gull decreasing. Redwinged Pratincole breeds; many wader species occur, including Chestnutbanded Plover. Threats include upstream dam building: reduced water flow could lead to frequent mouth closure and deterioration of mudflats. Fishing and bait collection are a problem; boating and all beach vehicles must be banned from the site. |
