Friends of Erith Marshes / Crossness Nature Reserve

The Friends of Erith Marshes Facebook page is a place for wildlife enthusiasts to share news, wildlife photos and observations from the whole of this area which includes Crossness Nature Reserve, the Southern Marshes, Thamesmead canals, Thamesview Golf Course, the various dykes within the Belvedere industrial area and from along the Thames Path towards Erith.


Friends of Crossness Nature Reserve

The nature reserve, which is a designated wildlife site within the wider Erith Marshes area, has a reserve warden, formal membership (giving access to the fenced ‘Protected Area’ – with its 2-storey bird hide, and a full colour newsletter), and an events calendar (including wildlife walks and hands-on habitat management sessions).  FoCNR does not currently have its own web platforms.

The reserve hosts rare birds, insects and plants.  It is the best mammal and best Dragonfly and Damselfly site in Bexley.

The £10 fee (£15 joint) now gets you life membership of the Friends Group.

Most of the site is outside the protected area and, along with Southern Marsh, is open to the public all year round.
