Anton Crescent Wetland is a one hectare Local Nature Reserve in Sutton in the London Borough of Sutton.
[1][2] The site is operated as a flood storage wash for Pyl Brook by the Environment Agency, and there is no public access.
The pools and mud provide a habitat for birds such as the green sandpiper and common snipe.
In 2005/6 the Environment Agency funded the installation of a pond-dipping platform and boardwalk.
[3] The entrance to the site is kept locked, but the reserve can be viewed from a footpath running along the back fence.
