The Guardian’s natural history writer draws on 20 years’ worth of reporting on topics ranging from red squirrels to lonely bats from Eigg to Canvey Island. From Norwegian wolves to protests against the HS2 railway, peregrine falcons nesting by the Thames to Britain’s last lion tamer, the acclaimed author of The Butterfly Isles and Badgerlands paints an ever-changing portrait of contemporary wildlife. His new book Wild Green Wonders presents thought-provoking interviews with conservationists, scientists, activists and writers such as Rosamund Young, Ronald Blythe and other eco-luminaries, including Sir David Attenborough and Brian May. He talks to travel and adventure writer Dan Richards.
