Wildlife along the River Weaver

The previously contaminated and derelict site at Anderton Boat Lift has been cleared of contaminated materials and silt. The area is now landscaped and provides safe habitats for wildlife.

During the restoration works, it was discovered that kestrels were nesting on the boat lift. The construction team made sure that the nesting birds weren't disturbed at any point, scheduling any works which might be a nuisance for after the birds had left their nest. The nesting site still remains for the kestrels on the restored lift and they are expected to return.

The river itself has a varied and rewarding ecology. Steep-sided valleys, never developed for agriculture or industry, retain their ancient woodlands - everything from oak trees to willow and silver birch. Such woodlands often support a wide range of flora.

But man has - sometimes inadvertently - done much to enhance the ecosystem of the Weaver Valley. The flashes created by mining subsidence are immensely valuable for wildlife. Their salty water encourages plants more usually found in coastal areas, and an exceptional range of birdlife.

Limebeds were formed where local industry offloaded its waste lime. Exotically coloured orchids grow here: there are good examples near the Anderton Lift.

The Weaver Navigation trustees also left their mark on local wildlife. Where the route has been shortened by artificial cuts, the original line of the river has become a quiet backwater and an ideal habitat.
