Ancient western red cedar tree falls in Stanley Park

A western red cedar tree that is believed to have beencenturies old fell in Vancouver's Stanley Park over the weekend, reaching the end of its life at what experts describe as a particularly stressful time for ancient trees in the area.

The immense tree was discovered on the forest floorSundaynear the intersection of the TatlowWalk and Lovers' Walk trails in the southwest corner of the park.

It was anywhere between 800 and 900 years old, according to local tree tour guide Colin Spratt, who runs tours for Ancient Trees of Vancouver.

"What caused this tree to fall was this 'heart rot.' And you can see the root structure is still actually in the ground," Spratt said in an interview at the park on Monday, pointing to the interior of the large tree which was almost hollow.

Spratt saidany number of stressors drought, pollution, fungi or insects could have led to the tree's demise, but the heart rot brought it down. Heart rot is a fungal disease that leads to decay in the core of a tree.

"Once it actually stops photosynthesizing and it's actually dead, then this heart rot really can take over," he said.

Spratt said the tree's collapse could be a symptom of a larger problem in Vancouver's largest park.

A number of western red cedars are facing increasing stress due to drought conditions, climate change,pollution and,locally,alooper moth infestation.

Spratt,amember of the University of British Columbia's Big Tree committee, said the Vancouver Park Board should consider watering the large trees something he saidwould be unthinkable in years without large-scale drought.

"It didn't rain in September and October last year, so these trees are actually under severe stress," said Spratt.

Joe McLeod, the park board'smanager of urban forestry, said large old-growth trees like the Western red cedar have historic significance for the First Nations on whose unceded territories Vancouver is built.

"It's always sad to see these veterans going to the next stage of their life," McLeod said.

McLeod said the fallen tree will now act as a "nurse log" as it decays, providing nutrientsfor newer species like the Western hemlock and red huckleberry.

Heacknowledged dead trees in Stanley Park could prove a problem for fire risk,though he said thefallen tree isn't a fire risk on its own.

Parkrangers are removingloose vegetation to cut down on potential fire fuels after the park board passed a motion to update Stanley Park's fire management plan.
