World’s largest tropical wetland burned this year

Record-breaking wildfires between January and June burned an ecological foothold — and biodiversity haven — spanning across Brazil, Bolivia, and Paraguay this year, just four years after similar fires burned 13,300 acres of the preserve.

The Pantanal is considered the world’s largest tropical wetland area, the world’s largest flooded grasslands, and one of the most important areas of freshwater in the world.

NASA captured some of the intense fires’ burn scars in satellite imagery.

“Fire season in southern Brazil usually starts in July and peaks in August and September,” NASA said. “The false-color images emphasize the burn scars (brown) from several of the fires. Unburned vegetation is green. Near- and short-wave infrared bands help penetrate some of the smoke to reveal the hot spots associated with active fires, which appear orange.”

The repeated fires have left the environment in a state of constant recovery — and nearby communities are struggling.

“We were just trying to recover from the 2020 fire, which devastated our Pantanal. We had not fully recovered and now we are facing this again,” said a volunteer firefighter with the Baia Negra Environmental Protection Area’s Association of Women Producers.

A recent report from MapBiomas Brazil, a collaborative initiative including NGOs, universities, and technology companies, sheds light on a major cause of the fires: surface water loss.

The Pantanal is the biome in Brazil that has dried up the most between 1985 and 2023. The report said annual water surface for the area last year was just under 944,000 acres — only 2 percent of the wetland biome was covered by water. The total is reportedly 61 percent under the historical average. The area was 50 percent drier in 2023 than it was in 2018 when the area’s last major flood happened.

“In 2024, we didn’t have a flood peak,” said Eduardo Rosa with  MapBiomas. “The year has seen a peak drought, which should last until September. The Pantanal in extreme drought is already facing fires that are difficult to control.”

The report also found that the entire Amazon region suffered a severe drought with a decrease of 8.2 million acres of water surface.

Up to 25% of Brazil’s native vegetation may be degraded

A new platform from the MapBiomas network shows that between 1986 and 2021 Brazil had between 11 and 25 percent of its native vegetation susceptible to degradation. This corresponds to an area ranging from 60.3 million hectares to 135 million hectares.

Fire effects over time
Visualized fire effects over 7 years, resulting from a single burn or multiple burns.

About 64 percent of Brazil — more than half the country — is covered by native vegetation. The beta version of MapBiomas’ degradation vectors platform makes it possible to generate unprecedented scenarios of the impact of factors that can cause degradation on native vegetation across  Brazil.

“This is the first time that degradation can be assessed in a broader way and in all Brazilian biomes,” says Tasso Azevedo, general coordinator of MapBiomas. “But we know that this degradation process occurs in other types of cover, such as agriculture and pasture, as well as soils and water, where we also intend to advance with this information in MapBiomas in the coming years.”

The degradation vectors considered by the MapBiomas team in this first edition of the platform include the size and isolation of the native vegetation fragments, their edge areas, the frequency of fire and the time since the last burn, as well as the age of the secondary vegetation.

Pantanal: fire as a factor in degradation

In the Pantanal, the degraded area can vary from 800,000 hectares (6.8 percent) to 2.1 million hectares (almost 19 percent). Although it is a biome that coexists with fire, the incidence of fires in the last five years has meant that 9 percent of the Pantanal’s forest formations, which are fire-sensitive areas, have been damaged.

Eduardo Rosa with the MapBiomas’ Pantanal team says some of the vectors of degradation in the Pantanal beyond this analysis must consider the entire biome’s surroundings, since all the rivers that naturally irrigate the Pantanal plain are born in plateau areas. “The removal of native vegetation for agricultural and livestock expansion unprotects the soil and interferes with the distribution of water and sediment. The quantity and quality of water that reaches the plains also depends on dams and hydroelectric plants that alter the natural flow of water,” he says. “Climate issues relating to rainfall and temperature regulate droughts and floods, and the increase in periods of drought has hampered the resilience of the Pantanal ecosystem.”



ON THIS DAY … 1994 and 2014

A little note and a little request — by Patrick Carnahan
 ~~ July 5, 2014
Still can’t believe we are only hours away from marking the 20-year anniversary of the fire on Storm King Mountain. I’m now 12 miles away from the parking lot I was in when Paul Harvey told us we’d just lost 14 firefighters on the mountain.

Our strike team had orders to go to that fire and we got stopped leaving camp and re-routed to another fire. We drove 3 times as long to fight another fire as it would’ve taken us to be on the South  Canyon Fire. We reached our assignment just as the flames were crossing the road into a remote community and we fought fire for the next 14 hours. Lost a wooden deck but no structures.

I remember everything in sight that night was on fire; it looked like hell, and there was no place else any of us would choose to be. Had about 4 hours of sleep and the first hot meal in 6 days when we got the news. Nobody really said anything at the time. We all understood we should’ve been on that mountain. Spent the next 5 days in a haze of smoke and flames before we were demobed. I have lost a couple of friends since then and many more I never had the opportunity to share the line with. Glad that the ignorance of youth was not wasted on me and I’m still here.

Asking that you all take a moment out of your day tomorrow and recognize those who never came off the line. Fire will always be a part of our reality and it will never be a job free of risk. When the next report hits the news about a wildland firefighter losing his or her life on a fire, please go here and make a difference:  The Wildland Firefighter Foundation.

Keep one foot in the black and stay safe out there. For those who have gone on, save me some line to work when the time comes.

And a revisit from a few years ago of one of Bill Gabbert’s best pieces:

Thompson Fire burns in northern California

Thousands were ordered to evacuate in northern California ahead of a fire  burning in Butte County, as an “exceptionally dangerous and lethal” heat wave in the West is building. Cal Fire reported that three firefighters suffered injuries on the fire and thousands of people were still evacuated early today  near Oroville. Several others were injured today. 

Soaring temperatures — forecasted to hold into next week – have parched the already-dry vegetation in the area.

The Mercury-News reported that the Thompson Fire has spread around Oroville Dam — the tallest dam in the United States — at one point burning on the dam itself.

Authorities initially evacuated more than 28,000 people from Oroville and  neighboring communities in Butte County, and by Wednesday the fire had grown to almost 3600 acres with zero containment and temperatures well into the triple digits.

Gov. Gavin Newsom declared a state of emergency for the fire area, according to CNN,  bringing on  additional suppression resources including the California National Guard.

The Mercury-News has a dandy photo gallery online; they reported that the Thompson Fire was one of a half dozen wildfires that started Tuesday in northern California and the Central Coast; it took off around 11 a.m. near Oroville.

More than 1,400 firefighters were working the fire, along with eight helicopters, 199 engines, and 46 bulldozers. Several large airtankers also were on the fire.

The town is about 20 miles south of Paradise, where the catastrophic Camp Fire killed more than 70 people in the 2018 disaster. The city of Oroville’s July 4 fireworks celebration was canceled by California State Parks on Wednesday.

Turkish wildfires threaten historic sites, ancient city of Assos

Turkey’s General Directorate of Forestry is battling a much higher number of wildfires this year compared with 2023; at this time last year, the country had recorded 513 forest fires, 665 other fires, and nearly 1500 total acres burned. As recently as June 24, those numbers have grown to 1093 forest fires, 1029 other fires, and nearly 8300 acres burned.

Aljazeera reported that at least 11 people were killed and dozens hurt as wildfires burned through villages in southeastern Turkey. Health Minister Fahrettin Koca reported the deaths from the overnight blaze between the cities of Diyarbakir and Mardin on Friday. Seventy-eight people were injured, with at least five people in intensive care units.

The elevated fire activity has resulted in increased aerial firefighting. The directorate has deployed aircraft over 4600 times thus far to fight the 2024 fires, and pilots have dropped over 16,000 tons of water. The total is a far cry from last year’s numbers of just 1100 deployments and only 3500 tons of water dropped.

Turkish fire at Assos

Turkey’s wildfire season has recently received national attention as a fire threatens the ancient city of Assos. The fire has burned 90 percent of the historic area, according to an Agence France-Presse report in the New Straits Times. The fire ripped through the ruins of the ancient port city of Assos, founded in the 8th century BCE near the Dardanelles Strait.

Ninety percent of the historical site of Assos was burned, said Mesut Bayram, mayor of Ayvacik district.

Assos, built on andesite rocks, is famous for its agora, theater, sarcophagi, and Athena Temple, according to Turkey Tour Organizer. “Also, this is where the world-famous thinker Aristotle founded a philosophy school.”

The fire was likely caused by a smoldering cigarette; xix helicopters, two planes, and around 35 engines are fighting the fire.
