Biodiversity Enhancement
Habitat Creation
Undertaken by the Castletown Estate, this scheme was encouraged by the RSPB and funded through agri-environment payments by Natural England.
Construction started in 2012 under the banner of ‘Project Canute’, and involved 32 days of bulldozing, creating a man-made creek to divert freshwater away from the area.
Some 5 ha of lagoons was dug, up to 1.5m deep.
A sluice with a self-regulating tide gate was installed (the design also installed at Black Hole Marsh and Lymington).
By 2018, the site was well established, sporting a variety of marine life, including saltmarsh plants, small fish and shrimps.
With the latter come a mix of migratory and other bird species, such as barnacle geese, egrets, herons, little ringed plover, redshank and oystercatcher.
Vegetation is controlled by occasionally raising water levels (Geertsema, 2018).
