Habitat Map

Habitat Teign Estuary Sections A, B and C represent different hypothetical habitat types. Scenario 1 shows no change in area for each habitat type under an elevated sea level. Scenario 2 shows that the area for all habitat types is reduced under an elevated sea level. Scenario 3 shows that the area of habitat type C is increased under elevated an elevated sea level. Interaction between sea level rise and topography and the potential implications for habitat types.
