The Fixing Broken Rivers Programme's next reedbed project will bring floating ecosystems to the most polluted section of the Lea Navigation in Tottenham. These state of the art reedbed designs are being installed in an area of the river which is too deep for traditional reed planting.
As they are floating, the reed’s root structure hangs within the watercourse – more pollution is broken down than in traditional reedbeds, and fish can shelter and feed in the roots.
Installing reedbeds can be difficult within the constraints of an urban river, so we’ve had to come up with novel ways of bringing reeds to the rivers. Recently we’ve constructed large vegetation frames and attached them to sloping concrete banks creating ‘green walls’. This 320m green corridor will not only tackle pollutants, but has provided some much-needed habitat on a section of the river devoid of vegetation.
