Winging it with old-growth trees

In this week’s newsletter, reporter Sarah Cox takes us to B.C.’s inland template rainforest, where biologists are getting creative with fake old-growth trees to save an endangered animal

“Are they still here?” biologist Cori Lausen wondered out loud in a clearing where old-growth trees once stood in B.C.’s inland temperate rainforest.

She wasn’t thinking about caribou herds — which are on the verge of local extinction in the globally rare ecosystem. Lausen was talking about the endangered northern myotis bat, as she showed B.C. reporter Sarah Cox the work her team is doing to save the tiny mammal — attaching plastic bark to dead trees to replicate old growth. 

That’s right: fake old-growth trees.

Decades of industrial logging have eliminated 95 per cent of the inland temperate rainforest; most ancient trees are gone. The bats provide billions of dollars of ecosystem services, for free! They need those trees for roosting as their population dwindles and a deadly fungal disease, which has killed millions of North American bats, creeps ever closer.

“The writing is on the wall,” Sarah told me. “B.C. is running out of wood. Mills are closing. We can either clear cut what’s left of our unprotected old-growth forests or safeguard them for wildlife, biodiversity and carbon storage — helping to address both the climate and biodiversity crises at the same time.”

While visiting B.C.’s inland temperate rainforest last summer Sarah didn’t spot any bats — the nocturnal creatures are rarely seen in daylight — but she became enamoured by the little fluffy mammals.

“I didn’t know bats played such an important role in the environment,” she said. “They eat buckets of mosquitoes and agricultural and forest pests. Bats have been on the planet for much longer than humans have — are we comfortable being the architects of their extinction? I suspect most people would say no.”

Lausen said it’s too early to tell if the fake old-growth trees are helping northern myotis bats. But, she told Sarah, it’s important not to lose sight of the bigger picture. The “number one solution,” Lausen said, is “don’t cut the trees down in the first place.” 

Take care and go to bat for wildlife,

P.S. Since I mentioned caribou, I wanted to tell you we’ve got a pretty in-depth read on when epic ski vacations and conservation collide. It’s coming on Monday, so stay tuned for it! The investigation has been several months in the making — but more on that later.

The lobbyists are at it again


The Narwhal’s climate investigations reporter, Carl Meyer, has once again dug up some stunning documents about a fossil fuel giant urging the Trudeau government to give two major facets of oil and gas development a pass on new climate rules — rules meant to crack down on heat-trapping pollution.

Go check out his investigation on recent oil and gas lobbying efforts over here!
