Canada’s record-breaking wildfires have widespread logging partly to blame

Author Hunter BasslerPosted on Categories ResearchTags , , 3 Comments on Canada’s record-breaking wildfires have widespread logging partly to blame

Quebec and Ontario’s environmentally crucial boreal forests had a tough wildfire season in 2023. The provinces had 12.8 million and 1.1 million acres burn, respectively.

The 44 million acres burned by wildfires across Canada have been attributed mainly to abnormal drought and high temperatures,  but a new study is pointing to another possible factor: the planting of millions of acres of immature trees after widespread logging. A recent study published by researchers at Australia’s Griffith University found more than 35 million acres of Canada’s forests have been lost to logging since 1976, including 20 million acres in Quebec and 14 million acres in Ontario.

The “loss” wasn’t caused by deforestation, which is “land that has been cleared of trees and permanently converted to another use” under Canada’s definition. Rather, the forest has been lost to forest degradation, or the conversion of naturally regenerating forest to plantations of planted trees.

“The Canadian Government claims that its forests have been managed according to the principles of sustainable forest management for many years,” the researchers said, “yet this notion of sustainability is tied mainly to maximizing wood production and ensuring the regeneration of commercially desirable tree species following logging,”

The decrease in the land area of older, more resilient forests across both Quebec and Ontario — and their subsequent replacement with immature trees — both lowered overall forest biodiversity and increased the prevalence of disturbances (wildfire, insect infestations, disease spread) over time.

“Logging has significantly increased the rate of disturbances in this region,” the report said. “This decrease in older forests when compared with historical natural conditions is accompanied by the resulting decline in structural attributes — such as large live and dead standing trees and coarse woody debris associated with older forests — which negatively affects biodiversity.”

Smoke reduced life expectancy across Washington

Author Hunter BasslerPosted on Categories SmokeTags , , 8 Comments on Smoke reduced life expectancy across Washington

Most of Washington State’s hazardous air pollution comes from wildfire smoke, burdening already over-burdened populations in the state and lowering the average number of years people in those communities are expected to live.

A new report from the state’s Department of Ecology looked into air pollution across Washington and found that the largest contributor to air pollution in over-burdened communities was from wildfire smoke. The DOE is working to improve air quality in 16 places, representing numerous communities, neighborhoods, and towns across Washington that are overburdened and highly impacted by criteria air pollution.

Targeted areas in Washington

The federal Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants. The DOE monitors these pollutants and acts if levels become unhealthy. These  pollutants are:

During the cold season, the largest contributor to air pollution was usually smoke from wood-burning stoves or furnaces.

Residents of the studied overburdened communities, on average, live 2.4 years shorter lives than the state average and also have higher numbers of deaths from cardiovascular disease.

“Long-term exposure to air pollution may contribute to development of disease — for example, asthma development in children or chronic cardiovascular conditions in adults,” the department’s report says. “Further, short-term exposure to air pollution is associated with exacerbations in existing conditions such as asthma or COPD.”

The overburdened communities included:

        • Spokane and Spokane Valley
        • Tri-Cities to Wallula
        • East Yakima
        • Lower Yakima Valley
        • Moxee Valley
        • George and West Grant County
        • Mattawa
        • Ellensburg
        • Wenatchee and East Wenatchee
        • Everett
        • North Seattle and Shoreline
        • South Seattle
        • South King County
        • Northeast Puyallup
        • South and East Tacoma
        • Vancouver

The report also warns that life expectancies in these communities may drop even further as the frequency of wildfire smoke events has been rising. The worry is in line with USDA research that points to wildfire seasons in Washington, Oregon, and Idaho that are projected to last longer with increased wildfire frequency, size, and total acres burned as a result of climate change.

“In Northwest forests, a warming climate coupled with more frequent wildfires will lead to a shift away from shade-tolerant, thin-barked, or fire-intolerant species such as western hemlock, subalpine fir, and Engelmann spruce,” the report said. “With warmer and drier conditions and more frequent disturbance, some locations will likely shift from forest to shrubland or grassland.”

Nearly double the usual winter wildfires, triple the acreage burned in northern India

Author Hunter BasslerPosted on Categories WildfireTags , ,

India’s Forest Service has reported 1,006 wildfire alerts to the northern state of Uttarakhand since November 1, according to the Times of India. That number is up from the 556 wildfire alerts the service reported during the same time last year.

The increase is part of a worrying and destructive cycle that has escalated in the area for the past six years. Uttarakhand has had triple the acres burned by wildfires since 2017, worsened by its first-ever repeated occurrence of winter wildfires, or wildfires outside of the state’s usual fire season of February 15 to June 15.

“The unusual shift in the fire season may be linked to different reasons including climate change, the lockdown, or too much human intervention in the forests,” Arti Chaudhary, the head of Silviculture and Forest Resource Management Division at the Forest Research Institute, told the Times. “A five-year study across 15 states of the country that witness forest fires, including Uttarakhand, has been initiated to thoroughly understand the actual reasons behind this shift, as it has been recorded all over the country.”

The winter wildfires also contributed to the state’s above-average wildfire carbon emissions in 2021. Uttarakhand’s wildfires emitted an estimated 0.2 megatonnes of carbon in March 2021 alone, breaking a record set in 2003, according to Copernicus Climate Change Service scientist Mark Parrington.

Northern India’s skies took on a hazy hue in November caused in part by the unusual wildfire shift, NASA satellites show. The haze is reportedly a seasonal occurrence caused by urban pollution entering the atmosphere when seasonal weather patterns trap air pollution near the ground, but smoke from the unseasonal wildfires made the air quality even worse.

“The World Health Organization considers 15 micrograms per cubic meter of fine particulate matter (PM2.5) to be a safe limit,” said NASA. “But ground-based air quality monitors routinely measured levels that exceeded 300 and, at times, 500 micrograms per cubic meter in November.”

Photos tell story of Maui wildfires’ destruction, aftermath and recovery

Author Hunter BasslerPosted on Categories WildfireTags ,

It’s been nearly five months since wildfires devastated Lahaina, on the Hawaiian island of Maui. Since then, images of the destruction have captivated the nation.

Honolulu Civil Beat has compiled collections of photos from each month of the aftermath, cataloging the desperation and the assistance that has flooded the area since the wildfires were controlled.

“We have thousands of images in our growing media database, of Lahaina and Upcountry, the victims and the landscape that were left in ash and ruin,” wrote for the Civil Beat. “In the past nearly five months, we’ve photographed numerous community gatherings, resource fairs, public officials in various settings from press conferences to legislative hearings. We’ve picked a smattering that we think represents the story that is continuing to unfold and we’ll publish these galleries at the end of each month.”

2023 Fire season: smallest number of acres in 25 years

Author Hunter BasslerPosted on Categories WildfireTags 3 Comments on 2023 Fire season: smallest number of acres in 25 years

Noxious smoke, zombie fires and the deadliest wildfire in modern U.S. history.

Wildfires made headlines numerous times throughout 2023, with the Lahaina wildfires on the Hawaiian island of Maui taking center stage in national media for months. For thousands of residents, recovery is still ongoing, with no end in sight.

Despite that, the year’s wildfire season was one of the quietest in decades. The National Interagency Fire Center estimated that 54,273 wildfires burned about 2.6 million acres. That’s the lowest yearly U.S. acreage burned by wildfire since 1998, when 81,043 wildfires burned 1.3 million acres.

The year is a relief for the wildland firefighters who are coming off  multiple high-burn years in a row, with 2015, 2017, and 2020 each  exceeding 10 million acres burned. The last time wildfires burned under 4 million acres was a decade ago when 63,312 fires in 2014 burned 3.6 million acres.

The reason for the low burn acreage could be attributed partly to 2023’s wet West. While the Eastern U.S. often has more wildfires, Western states see more acreage burned during the season. Thanks to above-average —  and some record-breaking — snowfall in states including California, Arizona, and Nevada, wildfires couldn’t find a foothold.

“Nine atmospheric rivers over a three-week period fueled the record-breaking snowfall,”  according to the National Snow and Ice Data Center. “The snow brought much-needed relief to the drought-stricken West, with the exception of the Pacific Northwest, where rapid snowmelt and early melt contributed to moderate drought conditions in late spring.”

While the U.S. saw relief, its northern neighbor dealt with a nightmare. Canada burned a record-breaking 18 million hectares (more than 44 million acres, roughly the size of North Dakota) during its 2023 fire season. The total blows the nation’s previous most-burned year out of the water, according to the Canadian National Fire Database. The country’s previous record year was 1980, when nearly 8 million hectares burned.

In contrast to the Western U.S. record-setting snowfall, much of Canada’s forests experienced drought and high temperatures heading into its wildfire season, Canada’s Drought Monitor shows. Severe drought was seen throughout the year, while extreme drought was seen in every month after April.

August ‘pyrotornado’ in Canada validated by researchers

Author Hunter BasslerPosted on Categories Fire behaviorTags , ,

A video that claimed to show a rarely-seen wildfire phenomenon went viral in August. Now, researchers have confirmed its legitimacy.

An “extensive investigation” led by researchers at Western University’s Northern Tornadoes Project in Ontario started after the video of a vortex above British Columbia’s Gun Lake was shared by numerous news outlets after it was recorded on August 18.

“The Northern Tornadoes Project has been investigating this event since that time — very carefully, given this was potentially the first fire-generated tornado that we have recorded,” researchers said.

Researchers first confirmed the location and date of the video, then had to determine whether the vortex shown in the video met the definition of a tornado. The project was able to determine the tornado’s validity through multiple visual indications from the recording, including the presence of a spray vortex at the base of the tornado, how the vortex formed and the position of the vortex over the fire, all of which matched the scientific research related to fire-generated tornadoes.

“Though the terminology in this area of science is still developing, it should be pointed out that this intense vortex was not a brief, fire-filled ‘fire whirl‘ but an actual tornado that is sometimes referred to as a pyrotornado,” the researchers said. “This is the first such fire-generated tornado recorded by [the Northern Tornadoes Project], and appears to be the most thoroughly documented fire-generated tornado so far in Canada.”

The researchers confirmed that, yes, the event is classified as a tornado. The full extent of the damage from the tornado isn’t yet known, but the project says evidence is trickling in slowly.

The pyrotornado isn’t the only one that’s been thoroughly studied. The “world’s first wildfire tornado” was captured on video in 2003 during a wildfire outside of Canberra, Australia. The fire destroyed 500 homes and killed four people. The damage was worsened when the pyrotornado emerged.

“The Canberra fire tornado of 2003 was rated an EF3 on the Enhanced Fujita Scale, with horizontal winds of 160 miles per hour, roughly equivalent to a Category 5 hurricane,” an article from Smithsonian Magazine reads. “As the first documented example of its kind, it was a milestone — another harbinger of 21st-century fire.”

A similar event was recorded during the 2018 Carr Fire in Redding, California, dubbed “the most destructive fire in National Park System history.” The fire destroyed 1,614 structures, killed seven people, and burned 229,651 acres. The fire also has a place in history for the pyrotornado it generated, which has since helped forecasters’ and scientists’ ability to identify future fire-generated tornadoes. NOAA researchers studied the pyrotornado, which had many similarities to the Gun Lake tornado.

“A key factor in the vortex formation was the development of a fire-generated ice-topped cloud (i.e., a pyrocumulonimbus), which reached as high as 12 km aloft,” NOAA said. “These observations will help forecasters and scientists identify, and potentially warn for, future destructive fire-generated vortices.”
