Chertsey Meads Local Nature Reserve is managed by Runnymede Borough Council.
Chertsey Meads is an open area of remnant floodplain meadow on the banks of the River Thames, adjacent to local schools and housing. Over 400 species of plants have been recorded, including flowers, grasses and sedges. 108 species of bird have been recorded including lesser whitethroat, reed bunting and sedge and reed warbler.
Some of the flowering plant species found in the grassland are unusual due to calcium carbonate that has been deposited onto the site when the Thames has flooded. These unusual plants, which are usually found in chalk grassland include meadow cranesbill and clustered craneflower.
