Nature area in London

About

Lower Colne is a Local Wildlife Site (reference M059) designated by London as a Metropolitan Site of Importance for Nature Conservation (SINC). It is located in the Borough of Hillingdon and follows the course of two rivers, the River Colne and the Wraysbury River. This Local Wildlife Site extends from grassland just north of the M4 motorway to grassland adjacent to the A3113 road and includes Harmondsworth Moor Country Park, Orchard Farm and Heathrow Colne Valley Biodiversity Sites.

The River Colne and the Wraysbury River originate as chalk streams and support aquatic plants including river water-dropwort, great yellow-cress, and pennyroyal. The site includes wet meadows, flooded gravel pits, and ponds, that provide habitat for kingfisher and water vole, while the rivers support a diversity of fish, including dace, chub and barbel.
