	This alone would not restore the full extent of natural processes and habitats. The oversized Greatham Beck would become a deep tidal creek and the floodplain would be inundated for long periods of time as a result of historic embankments and ineffective drainage.		This alone would not restore the full extent of natural processes and habitats. The oversized Greatham Beck would become a deep tidal creek and the floodplain would be inundated for long periods of time as a result of historic embankments and ineffective drainage.

	So the Project intends to restore the former meandering channel of Greatham Beck and the network of tidal creeks within the floodplain. Areas of higher land within the field parcel are proposed to be managed as grasslands for conservation purposes. Habitats would be allowed to migrate inland as sea level rises.

	The Greatham Marsh Restoration project is centred on the restoration of intertidal habitat on the low-lying agricultural land near Greatham Village. Historically, the village was on the edge of the marshes but is now inland from the remaining intertidal areas.
