If you want to abstract water it outlines where water is available for further abstraction. Section 3 of this document outlines the main principles of abstraction licensing that we follow in the catchment.

  • Lca 13.5 Misbourne Upper Chalk River Valley
    LCA 13.5 MISBOURNE UPPER CHALK RIVER VALLEY LCA in Context LCA XX LCA 13.5 MISBOURNE UPPER CHALK RIVER VALLEY KEY CHARACTERISTICS • Shallow chalk valley, gently sloping and indented by smaller dry valleys to produce smoothly rolling valley sides, with a relatively wide, flat bottomed floodplain. Valley sides steepening in the upper reaches. • On the valley sides the underlying chalk, and free draining lime-rich soils predominately support arable cultivation, with some calcareous grassland and woodland on higher slopes. • Ancient and semi-natural woodland associated with higher slopes and dry valleys, creating a visual boundary of the area, including mixed, broadleaved and coniferous woodland, which possess significant biodiversity and ecological value. • The valley floor is characterised by rough grassland, permanent pasture and paddocks, and divided into smaller scale fields, by low hedges and wooden post and wire fencing. • The narrow and gently flowing Misbourne River, meanders down the valley, with occasional ponds often located near farmsteads or small villages. The river often runs unnoticeably through this lower landscape. • A string of hamlets and farmsteads exist along the valley floor, with nucleated rows of larger settlements focused along roads. The larger village of Great Missenden is situated in the northern part of the area. Distinctive churches are often a feature of villages. • Post medieval parkland at Shardeloes and Missenden Abbey. Shardeloes House is a visually prominent feature on the valley side. • Varying patterns of field enclosure, with a mix of regular and irregular field boundaries. Large scale fields dominate the valley sides, with smaller scale field divisions along the valley floor.

  • Colne River Valley
    1. Colne River Valley Key plan Description The Colne River Valley Natural Landscape Area follows the Colne Within the northern Colne Valley, the settlement pattern is relatively River north to south on the western fringe of Greater London, from sparse, although there is a corridor of villages along the Grand Union Stocker’s Lake near Batchworth in the north to Heathrow Airport in Canal. To the south the valley is more densely developed than the the south. Between Batchworth and Uxbridge the valley floor consists north, with industrial towns such as Uxbridge, Yiewsley and West of a series of lakes and reservoirs, edged by ridges and plateaux within Drayton and London’s largest airport, Heathrow. The historic cores the neighbouring Ruislip Plateau (NLA 2) and the Hayes Gravels (NLA which remain within the settlements of Harefield, Uxbridge, West 10). As the River Colne meanders south and the Grand Union Canal Drayton and Harmondsworth suggest how settlement patterns have heads east, the topography gradually levels; historically the River evolved within this area. Despite the intense residential and industrial Colne would have meandered wider here, resulting in an extensive development around Uxbridge, the linear open space corridors area of deep silt soil across an exceptionally wide floodplain.

In the 1950s-60s changes in river engineering practices and agricultural intensification caused the water vole population to decline. These changes resulted in habitat loss and degradation which caused fragmentation and isolation of water vole populations. Since the 1980s an introduced predator, the American mink Neovison vison has decimated water vole populations as its range has expanded throughout England, Scotland and Wales. Mink are able to counter the water voles’ anti-predatory behaviours since they swim well, hunt efficiently and female mink are small enough to enter water voles’ burrows. The Berks, Bucks and Oxon Wildlife Trust launched its Water Vole Recovery Project in 1998. The aim of the project was to arrest the decline of water voles within the three counties and to work to stabilise and increase the water vole population.
