Wetland Vision Map of Historic Wetlands
Wetlands were much larger and more numerous in the past. Drainage, in particular over the last 500 years, has significantly reduced their area. Before then, a variety of habitats would have existed; wet, or sometimes only seasonally wet, and in many cases around the coast subject to saline or brackish conditions.

This map cannot show where wetlands existed at any given point in time because they have fluctuated so extensively over the centuries due to changes in climate and land management. It is not a definitive record of previous extent, but is based instead on underlying soil characteristics, and shows the maximum former extent of wetlands.
