SCIENCE OF FORESTS AND FLOODS IN BRITISH COLUMBIA: “A forest’s influence on flooding stems from the many random or ‘chancy’ features in a watershed,” stated UBC forestry professor Younes Alila in calling for a rethink of forestry practices and policy
“If we continue to mischaracterize (extremes), and if we continue to manage the forest and disturbance levels as if we were doing fine, we’re going to take the system further and further out of anything that is protective,” stated Dr. Younes Alila. And as climate extremes become more frequent and severe, he says, assessing the risks incorrectly could lead to greater damages and losses of life. He says frequency is the “lost dimension” in B.C. forest hydrology. It’s crucial to consider frequency because dikes and bridges can fail when battered by peak flows that are happening more often.
