Wetlands

River

Wetlands are home to several specialist species, some even able to survive feeding on plants in standing water. However, other vegetation is frequently present, sometimes with patches of carr woodland or drier land, which also support a wider diversity of species. Lowland raised bogs and upland blanket bog are home to many species, for example the Large Heath. The Swallowtail is only found in the Norfolk fenland of Britain.
