In Britain, the Norfolk hawker is protected under Schedule 5 of the Wildlife and Countryside Act 1981, and listed in Category 1 (endangered) in the British Red Data Books on Insects.
Its habitats in The Broads National Park in Norfolk, England are mainly Hickling Broad and two National Nature Reserves: Mid-Yare NNR and Ludham - Potter Heigham NNR.
The Norfolk hawker needs unspoilt grazing marsh dykes, clean non-saline water, rushy margins, and lots of aquatic plants, especially Water soldier Stratoides aloides.
