Dr. Patricia Raymond is a Forest Research Scientist with the Ministry of Natural Resources and Forests of Quebec. Patricia’s research interests include the ecology and natural regeneration systems of temperate mixedwood forests. She authored a foundational paper which established the three main variants of irregular shelterwood systems used in North America today. Using examples from experiments in mixedwood forest types, Patricia will review these systems and the subsequent research assessing the use of irregular shelterwood as a way to emulate natural disturbance dynamics that maintain structural complexity and ecological function.
