For more than a century, the yellow-cedar, a culturally and economically valuable tree in Southeast and British Columbia, has been dying. These trees, known best for their rich yellow coloration and naturally hardy properties, have slowly been decomposing, instead of thriving in area rain forests.
But until now, no one could say why.
“The cause of tree death, called yellow-cedar decline, is now known to be a form of root freezing that occurs during cold weather in late winter and early spring, but only when snow is not present on the ground,” Paul Hennon said.
