Hundreds of pink Fairy Puke globes scattered across a mint green carpet.

Fairy Puke Lichen

Among the myriad lichens that adorn and encrust the coastal rainforest, few are as striking as Icmadophila ericetorum. This mint-green carpet speckled with tiny pink globes is known as “peppermint drop lichen” or “candy lichen” to some, but in British Columbia, most prefer the evocative nickname “fairy puke lichen” to capture its unique blend of the sickly and the fanciful.

This lichen thrives on rotting logs in shaded and damp places. The green carpet is the lichen’s thallus which roughly corresponds to a plant’s leaves, whereas the pink globes (or perhaps “chunks”) are called apothecia and release reproductive spores, corresponding roughly to the fruits and flowers of a plant.

So next time you’re wondering what those interesting colours on a log might be, take a closer look and see whether it’s the leftovers of a forest fairy’s wild night out.

Rare swath of BC rainforest set aside for permanent protection

Nestled in the Selkirk Mountains the Incomappleux Valley is a rare 1,000-year-old Interior temperate rainforest

The province has committed to protecting the still-intact swaths of rare interior temperate rainforest in the Incomappleux Valley east of Revelstoke in a deal brokered by the Nature Conservancy of Canada.

The agreement, unveiled by Premier David Eby and Environment Minister George Heyman in Victoria Wednesday, calls for 750 square kilometres of the valley to be protected, 580 sq km outright as an official conservancy, 170 sq km as a restricted development zone.

The valley, nestled in the Selkirk Mountains 29 km east of Revelstoke, bears scars from logging in its lower portion, but its upper reaches that border Glacier National Park include pristine, 1,000-year-old stands of western red cedar and hemlock that are home to species at risk wildlife, including grizzly bears and mountain caribou.

“Incomappleux is one of the greatest treasures,” Eby said. “It’s home to old-growth cedar and hemlock trees that are four metres in diameter,” which the 6-foot-5 premier joked is “two of me sideways.”

And it’s home to 250 species, including rare lichens and rare bats. Eby characterized the conservancy as “one of the most significant protected areas established in the province in a decade.”

Conservation groups, including the Valhalla Wilderness Society, have campaigned for decades to protect the Incomappleux and raised the issue with Environment Minister George Heyman “continually almost since Day 1 of me holding this office,” he said.

Incomappleux Valley was one of nine old-growth zones identified for immediate deferral under the province’s old growth strategic review and former forest minister Doug Donaldson set aside 440 sq km to be considered for more formal protection.

The Nature Conservancy of Canada stepped into the discussions in 2018, recognizing it could play a role as a “facilitator and collaborator (to) bring together industry and governments and Nations,” according to Nancy Newhouse, the organization’s BC vice-president.

The conservancy is well known for brokering the purchase of private land for preservation, but Newhouse said it also works with companies on preserving connected ecosystems on public land.

In this instance, the conservation group raised $4 million via the Nature Canada fund from Environment and Climate Change Canada, mining company Teck Resources and two private foundations, the Wyss Foundation based in Washington, D.C. and Seattle-headquartered Wilburforce Foundation.

And the lumber company Interfor relinquished its cutting rights within the valley under timber licenses in exchange for a payment under terms of the deal.

Newhouse described the initiative as “a very important project in terms of the alignment with the global biodiversity framework,” under which Canada has committed to conserving 30 per cent of its lands as a means to protect biodiversity.

From the perspective of regional First Nations, the establishment of the conservancy means “we’re entering maybe into what should be just a stepping stone to improving what is actually happening,” in their traditional territories, said Kukpi7, James Toma of the Skw’lax te Secwépemcúlecw Nation.

However, while large parts of the Incomappleux with significant ecological values are being protected, much of the valley “is completely logged,” said forest ecologist Rachel Holt.

Holt, who sat on former Premier John Horgan’s old-growth expert panel, said groups have fought to preserve those high-value areas of Incomappleux for a long time, “which should have been, without question,” under existing policy.

“Nevertheless, a large conservancy is a positive step that will allow restoration of those ecosystems to occur,” Holt said. “That’s all good.”

As a first step, Holt said protecting the Incomappleux was a relatively easy decision because there was a rockfall about a decade ago that cut off road access to much of the valley “so it was not about to be logged.”

She added that the Incomappleux is bordered by other landscapes that are of equally high value as habitat where she hoped existing policy could also be used to scale back logging.

“What we have to do now is move these concepts forward and make some of the harder decisions,” Holt said.

Across the province, “all the valley bottoms, all the different low-elevation ecosystems are very under-represented in our protected areas,” Holt said.

“And that’s where the hard decisions are going to be in protecting ancient old growth that is absolutely irrecoverable,” Holt said.

Lobaria Lichen

The lobaria lichens such as lungwort and lettuce-lung play a crucial role in forest ecology. These lichens bear a superficial resemblance to human lung tissue, and so under the medieval medical belief known as “The Doctrine of Signatures”, they were used to treat pulmonary illnesses such as tuberculosis and asthma. Though the benefits of this belief proved to be only of the imagination, these lichens are in fact critical for the health of our planetary “lungs”, the temperate rainforests.

Lobaria lichens are able to accomplish the rare feat of fixing atmospheric nitrogen. Nitrogen is an essential nutrient for plant growth but almost no organisms are able to extract it from the air. These lichens mine this precious nutrient from the atmosphere and when they fall to the forest floor and decay, that nitrogen is made available to the entire ecosystem. These ecologically critical lichens are most abundant in old-growth forests where there may be as much as two tons of lobaria per hectare, all working tirelessly to enrich and fertilize the entire forest ecosystem.

Lobaria lichens are declining globally due to logging and pollution. The coastal rainforests of BC represent a critical global stronghold for these remarkable and ecologically valuable organisms.

Licorice Ferns

The licorice fern is a dainty forest dweller primarily found growing on mossy rock faces and the trunks and mossy branches of old-growth trees, sometimes hundreds of feet above the ground in the forest canopy. Licorice ferns are especially abundant on the branches of old big-leaf maple trees as well. Great examples can be found in Mossy Maple Grove and Mossome Grove.

These ferns get their name from the flavour of their rhizomes, which when exposed and nibbled on have a stevia-like sweetness mixed with that taste of black licorice…and dirt. The rhizomes can also be boiled to make a licorice-flavoured tea. Next time you’re in a forest with a lot of moss and maples, keep your eyes peeled for these cute ferns.

Slime Mold

Slime molds are among the oddest creatures of the rainforest. These frequently brightly coloured organisms represent an interphase between the multicellular bodies of plants and animals and the unicellular world of amoebas and other protists. These strange creatures live much of their lives as single-celled organisms but individuals eventually meld into a “super-cell” called a plasmodium, which is bounded by a single-cell membrane but contains many cellular nuclei.

This strange conglomerate being is observable in the forest as threads of brightly coloured “slime” creeping over rotting logs. This plasmodium is able to move through a process called “cytoplasmic streaming” as it hunts for microscopic prey along the forest floor. These plasmodiums can cover an area of 30 square metres despite being technically a “single” cell. When the food supply is exhausted the slime mold develops fruiting bodies to seed the forest with its spores.

Lab research has shown that despite lacking a brain or even a nervous system, slime molds appear capable of rudimentary learning, memory and problem solving. In one experiment slime molds even appeared to be able to learn from one another. These bizarre, contradictory creatures of the coastal rainforest are challenging our basic understanding of cognition, expanding our understanding of thought and memory.

Perhaps even more intriguing, the filamentous networks of slime molds are actually structurally very similar to the “cosmic web” of galaxies strung across the universe. Cosmologists have now started using slime-mold patterns to predict and understand the structure of the Universe and to help them map out the distribution of the enigma known as “dark matter”.

The careful hiker in the coastal rainforest will be on guard for inclement weather, unexpected cliffs, and possible bear encounters, but few will be prepared for the perils of drastic mind expansion that may result from an encounter with a slime mold.

Many old-growth forests where slime mold is found aren’t currently protected from logging. We encourage you to speak up for big trees and ancient forests in BC by sending an instant message to the BC government today.
