Why it's Wildland
4.8A small wildlife reserve where the Croydon and Carshalton arms of the River Wandle meet. Ponds, wetland, wildflower meadow and mature trees make a varied nature trail in the middle of South London.
Wilderness Island earns its name in two ways: part of it lies between arms of the Wandle, and it offers a pocket of varied habitat amid built-up Carshalton. Its modest scale suits a focused nature-trail visit, with ponds, meadow and woodland to explore.

Verified history
In the 1700s, the owner of Shepley House made ponds on the northern part of the reserve to keep carp for the household. The carp have disappeared, but some ponds remain. In the 20th century, successive housing proposals for the site were thwarted by local residents. London Wildlife Trust took on management in 1987, and the site was designated a Local Nature Reserve.
Hidden details
A pond with a changed purpose — One of the surviving ponds is now a long sedge bed; the ponds were originally made to hold carp for the household of Shepley House.
An island between two Wandle arms — The reserve is flanked by the Croydon and Carshalton arms of the River Wandle, though only part of the site is genuinely an island.
