The Chase Nature Reserve

Most of it is in the London Borough of Barking and Dagenham, with a small part in Havering.

[3][4] The Chase, together with the neighbouring Eastbrookend Country Park, is also designated a Site of Metropolitan Importance for Nature Conservation.

[5] The River Rom, which is the boundary between the boroughs, runs through the site, with Barking and Dagenham on the west side and Havering on the east.

Other animals include water voles, great crested newts, slow worms and badgers.

[7] The reserve is divided into a wooded narrow strip along the River Rom north of the road called The Chase, and a large more open area with lakes to the south.
