World's End fields wetland scheme

1. The purpose of this contract is to restore and enhance the biodiversity interest of the Worlds End fields which Natural England manages as part of the National Nature Reserve and to support the integrity of the adjoining Bettisfield Moss NNR as constituent parts of the SSSI/SAC. To enable this to happen the World's End Fields are to be subject to a more favourable but managed hydrological regime conducive to the restoration of characteristic wetland habitats; and necessary for long-term conservation of the peatland resource

2. The main aim of the Scheme is to disconnect the under-drainage in the fields and re-capture the water flowing into the World's End Drain from Bettisfield Moss and from the field's original mineral catchment in order to rewet the fields and recreate bog edge (lagg) habitat. Underdrainage will be stopped by installing bungs in existing manholes. This will minimise soil disturbance.

3. To stop retained water running on to other owners' land or the unadopted lane in flood conditions or if the under-drainage pump breaks, the Scheme involves constructing a clay flood embankment around part of the margin of the fields. Outlet pipes through the north-east corner of the bunds will feed excess water to the Lord Hill culvert by gravity along a new ditch also fitted with flood banks through a new culvert at Brook House Farm. Penstocks will control water outlet through the flood embankment.
