Repeat photography is the practice of taking photographs of a specific location at two or more different times. It is a powerful visual resource for scientific study and education in forest and landscape management.
From working forests to wilderness areas, such photographic pairs or sequences can help us understand ecosystem processes, and effects of human and non-human disturbances. They can inform our concepts of sustainability, help us understand the implications of public policy, and assess the results of management decisions.
