Butterfly protector who informed climate change policy gets OBE

Dr Martin Warren has saved at least three species from extinction, laying the ground for landscape-scale conservation

Every June on Exmoor and in woods near Canterbury, a fragile-looking golden butterfly called the heath fritillary flutters in the sunshine.

It would probably not grace summer woodlands and moors were it not for the efforts of Dr Martin Warren, a scientist and conservationist who has been awarded an OBE in the New Year honours list.
