Brian Carter was an artist, poet, columnist, children's author, naturalist and broadcaster who influenced a generation of nature writers.

His six novels all explore man's relationship with nature, the first of which, A Black Fox Running, was published in 1981. His art was exhibited at the Royal Academy in London and at galleries in Paris, Germany, Holland and Canada, and he had a one-man show on London's West End.

He fought and won many conservation battles for the English countryside and had a great love of the natural world, particularly of Dartmoor, living in sight of it for most of his life, spending time outdoors there walking, cycling and playing football.

He contributed to every edition of West Country newspaper the Herald Express from the early 1980s until his death in 2015. He is survived by his widow Patsy, his children Christian and Rebecca, and three grandchildren.
