In The Tree In Changing Light, Roger McDonald meditates on our unique landscape and its rich tapestry of native and introduced trees, which 'give language to our existence'. His most intimate and personal book to date, it also celebrates country men like his grandfather Chester Bucknall, a forester and pine-planter, of whom he writes, 'I believe him to have been a dreamer about trees'; Wilf Crane, Roger McDonald's mentor with trees who flew planes across country on solo planting raids and whose death while flying inspired this book; and Tom Wyatt, a bush gardener whose dedicated hands made trees bloom in Queensland towns.
