Old River Severn, Upper Lode (grid reference SO880331 ) is a 3.72-hectare (9.2-acre) biological Site of Special Scientific Interest in Gloucestershire, notified in 1985. It is a cross county border site between Gloucestershire and Herefordshire and Worcestershire.^[1]^[2]

Location

The Severn at this site is an old meander which was cut off from the main flow of the river when Upper Lode lock was built. It is a relatively quiet backwater that joins the Severn at the south end.^[1]

Habitat and flora

The meander now supports a diverse range of habitats as a result of the seclusion. These in turn support a variety of plant life and there are at least six nationally rare species. The channel has silted up at the furthest part from the main river. Where spoil has been dumped historically in the channel the area has become rough grassland.^[1]

Habitats are open water, marginal mud, inland saltmarsh, willow carr, neutral grassland, scrub and woodland. The main river controls the level of the water which fluctuates as the Severn is a tidal river.^[1]

Aquartic plants supported are pondweed, flowering rush, water forget-me-not, water-cress and water dock. There is white willow, crack willow and osier. In the area of rough grassland the nationally rare swamp meadow grass may be found. Woodland trees include alder and ash as well as willow.^[1]

Nationally rare species supported include greater dodder which parasitises nettle. There is also tasteless water-pepper, small water pepper, mudwort and needle spike rush. This is the only known site in Gloucestershire for small water pepper, mudwort and needle spike rush. Narrow-leaved water plantain, keeled garlic (Allium carinatus), glaucous bulrush (Schoenoplectus tabernaemontani) and sea club rush (Scirpus maritimus) are also recorded.^[1]

Fauna

Birds include mallard, coot, Eurasian reed warbler and sedge warbler. Kingfisher are present and waders are reported such as redshank, common sandpiper and lapwing. Dragonflies are present including the relatively scarce hawker and white-legged damselfly.^[1]

The Cotswold Water Park is the United Kingdom's largest marl lake system, straddling the Wiltshire–Gloucestershire border, northwest of Cricklade and south of Cirencester. The lakes were created in the second half of the 20th century by extraction of glacial Jurassic limestone gravel, which had eroded from the Cotswold Hills, and these filled naturally after working began to cease in the early 1970s.

Bookham Commons are two commons, situated just to the north of the villages of Great Bookham and Little Bookham, in Surrey, England, 154.7 hectares in extent; the individual parts are named Great Bookham Common and Little Bookham Common. A group of dwellings known as the Isle of Wight is situated within the site, and a track, Common Road, leads to it from the northwest. Little Bookham Common lies south and west of this track, whereas Great Bookham Common lies to the east.

Coombe Hill Canal lies in the Vale of Gloucester, south west England, north of Leigh and runs west 2.75 miles (4.43 km) from Coombe Hill Basin to the River Severn near Wainlode Hill. It opened in 1796 and closed 80 years later in 1876, after the only lock was damaged by flooding. The Gloucestershire Wildlife Trust purchased the Coombe Hill Canal nature reserve in 1985 and the area is managed by the trust. Adjacent to the Coombe Hill Canal is a large area of wet meadowland situated midway between Gloucester and Tewkesbury to the west of the A38, which was purchased by the trust in 1999. There is a north and a south meadow. This land and the Canal itself often flood in winter, which attracts hundreds of wildfowl.
