Project summary

Edit project overview to modify the project summary.


Friends of Barnes Common in partnership with LBRuT have created a new reedbed on the Beverley Brook 400m2 (20 x20) adjoining to the Beverley Brook. Wider aim of the project is to link up the reed beds in Richmond Park and the Wetland Centre. Create a new habitat for Barnes Common. Structural tree line/invertebrate productivity for foraging bats, plus bat roost potential; backwater; scalloped bays for marginal plants.

Best practice management plan for commuting, foraging and roosting bats; watervoles, fisheries benefits and flood defence benefits; improvement of bankside for marginal plants and/or fringing reeds, strengthening wild life corridor along brook for birds, water voles, grass snakes, bats etc; enhance bankside marginal vegetation and provide suitable habitat for birds, invertebrates, plus potential for dispersal for the BAP species from London wetland centre e.g. water vole, grass snake; readily accessible to the public; forage area for bats.

Lessons learnt

Edit project overview to modify the lessons learnt.


London Borough of Richmond with Friends of Barnes Common has created a 400 sq m reed-bed with ditch links to Beverley Brook. More marginal plants will be added this Autumn with further fine tuning if needed. The construction work started in February 2010 and took two weeks. Planting commenced in April 2010 and has continued through to August 2010: the early reed and yellow flag planting has been very successful, and with these (sourced from the local Kew pond) came limited quantities of Sweet Galingale sedge, greater willowherb etc to which we have thus far added marsh marigold, meadowsweet, purple loosestrife, hemp agrimony and ragged robin. The plan has always been that this site should be 'reed-fen' which is flooded in winter and dries out but stays moist in summer - and it appears that we have broadly achieved this aim, with the site dry at times and ponding when there is heavy rainfall, which is helping to maintain the new plantings, but which would drain out if we opened the sluices: equally the brook depth in winter, with sluices open, should allow a period of consistent flooding for weed control and to allow a backwater haven.
