Another casuality of the climate crisis is Vancouver's famous Stanley Park, one of the most beautiful parks in the world, where one quarter of the trees are already dead or dying during this year's drought.

The trees of Stanley Park, typically the green jewel of Vancouver's downtown core, just can't catch a break. Experts say large numbers of browning trees appear dead or dying, because of a one-two combination of foliage-munching grubs and an exceptionally dry weather spell, with the last appreciable rain falling in Vancouver on Sept. 4.
City of Vancouver arborist Joe McLeod said trees already stressed by infestations of western hemlock looper moth larva have been further pushed toward breaking point by the prolonged summer-like conditions. "Much like humans, the more stressed we are, the more susceptible we are to getting colds and other conditions,'' said McLeod. "Unfortunately, I think the fact that there is an insect outbreak that is happening and the fact that we have very extreme heat and then extreme cold — it's definitely lending itself to a worse situation than previous years."
Such "multiple layers of stress" added up to a higher likelihood of tree mortality, said McLeod. Dead trees could be seen in the park's Prospect Point area, as well as facing Coal Harbour, English Bay and the northern edge of the park, said McLeod.
Richard Hamelin, the department head of forest conservation sciences at the University of British Columbia, agreed that it's not just the ongoing problem of the looper moths that is killing trees. "The heat and the drought are like additional stress that affects those trees," said Hamelin. "If it were just for the insect, maybe the trees would recover," said Hamelin, who has been monitoring the health of trees throughout the park over the past four years.
