Last night the London Wildlife Trust hosted a talk by the urban explorer, researcher and walker (in conjunction with the Friends of Belair Park) at the Belair Park recreation rooms, just off Gallery Road. This is particularly germane for the Friends as the River Effra is currently being released from it's concrete captivity this week as part of the Lost Effra Project
The Lost Effra Project was launched by London Wildlife Trust in January 2013, commissioned by Defra and the Carnegie UK Trust, to develop a community-based water management strategy aiming to inspire people to create new ways to manage the water environment in their area. Community groups are working to improve local green infrastructure to make Herne Hill and its surrounding areas more resilient to flooding and improve the natural environment for wildlife.
(There are striking parallels here for us in Kingston as we too have been rethinking the Hogsmill river and South East Rivers Trust have been undertaking some local 'rewilding' to assist the river, in performing its functions, in a more natural way).
This is what the Telegraph said about Tom Bolton's book Londons-lost-river's in 2012 and this is what he says about himself as thankfully like myself, he has a blog
In addition to the Effra Tom discussed nine 'captive' rivers including the: Fleet, Tyburn, Neckinger, Westbourne even the Wandle, whose Croydon stretch is culverted. He didn't stray into Kingston though, so we should tell him about the coombe-conduit which runs to Hampton Court from two locations at Kingston Hill.
