Fire that ordinarily helps the boreal black spruce forests now threatens them too

This is an excerpt from an article at Canadian Broadcasting Corporation.

Warmer, drier conditions that lead to more frequent fires in Canada’s vast boreal forests are threatening the dominance of black spruce trees that for thousands of years thrived in a healthy relationship with forest fires.

Black spruce trees and the thick layer of peat they take root in are great fuel for the fires. So typically, every 100 years or so, a fire would sweep through and take out a stand of these iconic boreal trees.

That same fire would warm up the black spruces’ waxy cones, releasing its seeds that would allow the black spruce forest to regenerate.

But in recent years, climate change has undermined the healthy relationship between black spruce trees and forest fires. More frequent wildfires are pushing large areas of black spruce forests past their recovery point.

As a result they’re being replaced by other species, and sometimes the forest doesn’t regenerate at all.

“We do see evidence of shifts away from black spruce dominance in more than one third of the sites,” said Jennifer Baltzer, the Canada Research Chair in Forests and Global Change at Wilfrid Laurier University.

This shift away from black spruce dominated-forests could have far reaching implications for the wildlife that depend on them — like caribou — and for the massive amount of carbon these forests store underground.

Baltzer is the lead author of a new study that analyzed more than 1,500 former burn sites across the North American boreal forest, between 1989 and 2014.

“This is one study, in a growing body of evidence, that we’re pushing ecosystems toward these tipping points that we don’t really know what comes next,” Baltzer told Quirks & Quarks host Bob McDonald.

A study evaluated the cultural safety of indigenous wildland firefighters in Canada

From a recently completed study in Canada:

Funded by Natural Resources Canada, a project provided preliminary data on cultural safety and occupational health and safety that is necessary to improve the understanding of Indigenous perspectives on wildland firefighting and wildland fire operations across what is now called Canada.

Wildland firefighting is a unique occupation. For decades, Indigenous (First Nations, Métis, and Inuit) firefighters and fire operations staff have been engaged in wildland fire suppression activities, formally and informally. They are increasingly being called upon by their communities and the broader wildfire management agency community in Canada to engage and deploy in various wildfire suppression and related duties. In the past decade, we have seen an increase in wildfire activity and the number of communities put at risk or impacted by high-intensity wildfire events. Due to the nature of this work, Indigenous Peoples engaged in wildland fire suppression activities routinely work in hazardous situations and stressful environments – impacting their physical, mental, and spiritual/cultural well-being.

Giving Voice to Cultural Safety of Indigenous Wildland Firefighters in Canada was a multidisciplinary, collaborative team-based project.

From January – July 2021, the Turtle Island Consulting Services Inc. (TICS Inc.) Project Team explored the following set of questions:

  • What are Indigenous wildland firefighters’ and wildland fire operations staff’s experiences regarding accident/injury rates, sickness presenteeism/absenteeism, chronic illness, close calls, racism/ discrimination/harassment?
  • What is currently working on the fireline and fire operation centres to promote cultural safety of Indigenous wildland firefighting personnel?
  • What are the priority needs/issues and recommendations for enhancing cultural safety for Indigenous wildland firefighting personnel?

The TICS Inc. Project Team developed an online survey and virtual circles were conducted specifically for individuals who self-identified as Indigenous and worked in wildland firefighting and/or fire operations for at least one fire season in Canada. These participant selection criteria supported the sharing of Indigenous Peoples’ voices in culturally safe spaces to help (i) increase the understanding of their jobs, (ii) enhance overall satisfaction from a cross-cultural perspective during this important work, and (iii) aid in making the future of wildland firefighting more enjoyable, safer, and culturally inviting.

Firefighting help arrives from Quebec

On Wednesday 40 firefighters from Quebec, Canada arrived in the United States to assist in suppressing wildfires.

In Boise they received an orientation briefing and fire shelter deployment training at the National Interagency Fire Center. The crews have since traveled to the Schneider Springs Fire on the Okanogan-Wenatchee National Forest in Washington.

The National Wildfire Preparedness Level has been at 5, the highest level, for nearly two months. Currently, 99 large wildfires are burning across the western U.S., with 57 of them having a strategy of full suppression.

For the last couple of days wildfires in Southern British Columbia have been producing large quantities of smoke which has been drifting into Alberta, North-central US, the American Midwest, and points further east. The forecast for Saturday night indicates this trend is continuing.

Clouds have made it difficult for satellites to photograph smoke coming from the Bootleg Fire in Oregon and the Dixie Fire in California.

British Columbia bracing for very high temperatures as fires prompt evacuations

As of Wednesday night BC had 248 active fires, 36 of which were designated “fires of note”

British Columbia is having another year with higher than average wildfire activity due to hot, dry weather in recent weeks.

British Columbia Public Weather Alerts, 7 a.m. PDT July 30, 2021
BC Public Weather Alerts, 7 a.m. PDT July 30, 2021.

On Thursday in Lytton, BC the temperature reached 47.9 degrees Celsius (118F), the highest temperature ever recorded in Canada.

Hot weather is expected to continue through Saturday with many areas in the southern part of the province under Weather Alerts for heat where temperatures could reach or exceed 37 degrees Celsius (100F) while the relative humidity will be in the teens. The wind will be moderate in most areas, 5 to 7 mph with gusts to 8 or 10 mph.

Forrest Tower, a spokesman with the wildfire service, said, “We may get a bit of a break from the wind as this ridge kind of has a stable air mass over these fires, but the added challenge is that even if it may not be strong winds, any wind will have a significant influence on these fires.”

June’s extreme heat affected the fatality rate in BC. From the CBC July 29, 2021:

B.C.’s chief coroner has confirmed the majority of people who died suddenly during the week of June’s record-breaking heat wave lost their lives as a direct result of the extreme temperatures.

Lisa Lapointe confirmed in an interview Thursday morning that 570 of the 815 sudden deaths recorded over that time period — 70 per cent — have now been deemed “heat related.”

“[If not] for the extreme heat, they would not have died at that time,” Lapointe said during an interview with CBC’s The Early Edition.

According to Lapointe, 79 per cent of those who died were 65 or older.

As of Wednesday night BC had 248 active fires, 36 of which were designated “fires of note” that were highly visible or posed a potential threat to public safety. The 3,693 personnel assigned to the fires includes 316 from out of the province and Australia.

Currently there are 62 evacuation orders in effect for 3,443 properties.

For weeks the fires in BC have been producing dense smoke that generally spreads to the east and occasionally into the United States.

Here is the smoke forecast for 9 p.m. MDT July 31, 2021.
