Gabriel is a semi-professional photographer of trees and forests. His images have been shortlisted for awards, and featured in magazines, books, merchandise, and international advertising campaigns. Having a creative eye, he has curated exhibitions at a number of UK venues, including Art in Action, Royal Botanic Garden Edinburgh, and Oxford University Museum of Natural History.

He has worked widely in collaborative science programmes, ranging from genetic tree improvement to silvo-poultry research. During the 1990s and early 2000s, he created a centre dedicated to hardwood research at Paradise Wood in Oxfordshire, planting many tens of thousands of trees.

Gabriel played a key role in Our Forests, working with six other leading environmental campaigners during 2010-11 to save England’s public forests from government disposal.
