Forest Wildfires

I know it’s winter, but we need to talk about wildfires. There is a common, simple-minded view—popular among those who deny climate change—that overzealous park employees unnaturally suppressed fires, causing wildfires today. End of story. Once we ‘catch up’ on the ‘fire deficit’ everything will be fine. This is bunk.

Last year Canada had a record-smashing year of wildfires, and the frequency of wildfires far exceeds what is normal, considering the naturally slow growth rate of trees in boreal forests. Most of these fires were in remote northern Canada, where historic fires were not even reported, let alone suppressed. The estimated number of fires was not too high, but many of the fires were mega fires, burning over seven times as many acres as the modern historic average. There is only one explanation for the scale of the wildfires last year, and it isn’t Smokey the Bear. The primary cause of increasingly severe forest fires is carbon pollution. 

The first humans to change natural fire ecology in North America were natives who for centuries used fires in the valley for agriculture and to attract game with new grass. The most destructive humans by far were loggers who clear cut whole forests. During the Great Depression, roads and campgrounds were developed in both old and regrown forests, bringing millions of visitors who parked their hot cars on dry grass, dropped their cigarettes on pine needles and left their campfires unattended, causing a dramatic increase in forest fires. Firefighters responded by putting out fires when they threatened nearby communities.

We changed forest fire ecology in complex ways over centuries, so the simple ‘fire suppression’ explanation is false. We don’t know exactly what the forest’s natural ecology was like before man started playing with fire here, but man’s brief experiments for a few decades last century—causing wildfires due to camping and suppressing some fires at the edges—all account for maybe 2% of the life of a Giant Sequoia. Yosemite park rangers tracked all fires within the park since the 1930’s, and for decades none of the fires were large enough to matter to the overall health of the forests until recently. Past fires were often 100 or maybe 1000 acres, but recent forest fires are 100,000 or 1,000,000 acres. Our hotter climate has changed everything. Now we need to change our perspective from our recent past to the consequences of our carbon pollution on the future. Extinction is not a mistake we can correct later. 

California has the most national parks with 28 park units, and about 12 of them have some type of large forest, often wilderness. I’ve been in all of those forest parks in the past year or so, and 9 now have huge swaths of dead trees from recent wildfires. 

Only Muir Woods, a small coastal redwood forest park along a creek surrounded by wealthy suburbs, has been spared. Pinnacles has had multiple wildfires in the past three years, but firefighters managed to contain them quickly. Even foggy Redwood park lost 11,000 acres in 2003 due to the Canoe Fire. 

This level of wildfire is not normal; it is out of control, and it is getting worse. Discussing past firefighting efforts and increasing the rate of manmade fires is not going to fix the problem. If we do not stop our carbon pollution, then 100 years of environmentalists’ efforts to save these forests for future generations will be wasted. 

Lassen Volcanic National Park

This boiling mud pot in the Sulphur Works area is so close to the road that the shoulder has collapsed. There’s a parking area a minute walk away and the views include many other steamy volcanic features, rough landscapes broken by eruptions and snow in July. The trail to the larger Bumpass Hell area was blocked by snow from the parking lot. I didn’t care, since I’ve been there before with my kids, before the fire. We stayed at Drakesbad Guest Ranch with their amazing natural hot spring pool where we swam and floated under the Milky Way, one of my fondest memories of any national park.

In 2021, the 1 million acre Dixie Fire severely burned 70% of this Northern California park, mostly the wilderness area. With Mount Lassen over 10,000 feet, many of the trees in the park grow extremely slowly, so the fire damage will be visible for up to a century, assuming we don’t have another fire before the forest can recover. Like much of the park, Drakesbad Ranch is still closed, although most buildings were saved. The devastation is terrible to see.

The park newsletter does not mention the Climate Crisis in a complete denial of reality, but it did congratulate itself for ‘30 years of fuel reduction that decreased burn severity’. We now live in the Pyrocene Epoch, the Age of Fire, where man has created conditions for multiple million acre fires each year, when the most beautiful places can be destroyed in a few hours. Once we imagined our parks would be there for future generations to enjoy. Now we wonder if they will still be there for our next vacation.
