Rennie Montague Bere CMG (28 November 1907 in Bere Regis, Dorset – 23 March 1991 in Plymouth, Devon) was a British mountaineer, naturalist and nature conservationist.
In 1955 he became Director and Chief Ranger of the Uganda National Parks.
Bere published about a dozen books including The Way to the Mountains of the Moon (1966), Antelopes (1970), The Nature Of Cornwall (1982) and his autobiography A Cuckoo's Parting Cry: a personal account of life and work in Uganda between 1930 and 1960 (1990).
In 1935, when on leave from Africa, Bere and David Cox made the first ascent of Climbers Club Ordinary on the Dewerstone in Devon, a climb which is featured in the compendium Classic Rock[1] and was the first recorded route on the Dewerstone,[2] a cliff which "offers the finest climbs" on Dartmoor.
Bere researched many inselbergs, the Imatong range on the Sudanese border and the Virunga volcano.
