- We’ve done a lot of damage to our forests over the years through logging and poor fire management. All this has led to the devastating fire seasons that currently dominate the western United States. But the U.S. Forest Service has learned a lot since then and now knows the benefits that the right kind of fires can have on the ecosystem. Follow firefighters and ecologists as they perform a prescribed fire and demonstrate the power that these low-intensity fires possess.

Adding fuel to the fire is usually not a good thing, especially when it comes to forests that are already wrecked by massive fires every year. So setting any fire on purpose doesn’t exactly sound like a good idea.
But the professionals in hazmat suits pouring fire on the ground are actually saving these forests from those devastating, out-of-control fires we see on the news.
Cuz over time we’ve learned that forest management isn’t always about saving the trees. Sometimes it’s about burning them. Down to the ground.

Indigenous Tribes Have Been Rekindling The Ancient Art of Controlled Burning
“Indigenous people have been practicing controlled, deliberate burns in North America, and around the world, for millennia. For the Yurok, Karuk and Hoopa Tribes of Northern California, human-managed fires across their traditional lands are vital.”

On the French Meadows Restoration Project
“The 28,000-acre French Meadows Forest Restoration Project is using a collaborative, all-lands approach to restore forest health and resilience and reduce the risk of high-severity wildfire in the headwaters of the Middle Fork of the American River, a critical municipal watershed located on the Tahoe National Forest in California’s Sierra Nevada.”

Bureau of Land Management - Why Do Prescribed Burning?
“Some forests and rangelands are more vulnerable to environmental stress (drought, insects, disease, and invasive species) without the role of low intensity frequent fire. Land management agencies use prescribed fire in a safe and carefully planned manner to help reduce wildfire risk to communities, municipal watersheds and other values, as well as restore natural ecologic processes and functions, and to achieve integrated land-management objectives.www.blm.gov/or/resources/fire...

Some plants actually have to burn to spread there seads.
Love to see this!! As someone from Canada I can confirm that the problem isn’t just in the states but here as well! Many of our forests are young and so thickly overgrown it’s like trying to walk through a jungle with the amount of dead brush on the ground. No joke I’ve had to use a machete while hiking trails on my friends property to carve out the path on multiple occasions
With all the megafauna gone there is nothing to eat and move the brush.
This is what they call, fighting fire with fire
Literally

Great episode, please educate people on types of plastics so that they can better understand different types and avoid those that are hard to recycle
As a firefighter myself, I approve of this method. I have known that for years, and it was even covered in my training.
A classic case of using fire to fight fire!
more prescribed fires now = fewer high intensity fires later SAY IT AGAIN FOR THE PEOPLE IN THE BACK
It is great to see videos like this! Another vital step is since the US forests are so overgrown, after 100 years of aggressive fire prevention, we need to mechanically thin the forest to reduce the risk of high severity fire before a prescribed burn.
Controlled burns are important to get rid of some fuel in the fuel, heat, oxygen, and a chemical chain reaction of the Fire Pyramid.
North American forests are actually dependant on fire, this HAS to be done here. not necessarily in other coutnries, like those with rainforests.
Ok, I see the benefits of this, but how is the wildlife protected during this controlled process?
Most of them are adapted to fires, so they aren't a huge problem. U could check out Smarter Everyday's video on this topic.
I would assume by hanging out a noise maker a few days before to get rid of most of them.
And the rest, who can't run away even after that, humans running around and generally being loud and a slower than normal approaching fire, will be taken care of by natural selection. At least their relatives get to repopulate early in freshly empty homes, instead of literally the entire race being wiped from the forest.
@@Arkios64 no noise maker. But these prescribed fires are generally not spreading any faster then the line of people walking lighting them with drip torches or fusees. Most wildlife slower than a walking person is probably adapted to hide in holes or similar to escape fire.
Me walks outside and starts my one and only tree on fire.
2:30 that's a kurzgesagt forest! :)
Great to see your hard work paying off Niba! Nice video!
very cool! i'm definitely curious about other ways we could make our forests healthier, and if this "overpopulation" is also true of forests that don't typically get huge forest fires (e.g. on the east coast?)
Mechanically thinning is a useful tool to reduce tree density and remove insect and disease problems in the process.
Arkansas forestry service has been doing controlled burns for a very long time. Arkansas does have wildfires occasionally, but firefighters are able to control them easier and put them out faster.
Hazmat suits!? Weird. The outfits are flame resistant Nomex.
An amazingly informative video. Love it! Thank you for putting this together.
Important to say that this applies to north american forest not the amazon rainforest or the Pantanal
The idea of "managing" forests is so hubristic. These forests have maintained their health for millions of years without our intervention. Nature has had billions of years to adapt solutions through evolution.
It’s not just about the forests themselves. These fires can take out houses or even whole towns and national parks also get fires. Just because forests are normally in remote areas doesn’t mean there isn’t always people there or near them
Hey, It's me! Destin from SmarterEveryDay made a video about this as well in the past.
Love this video! We can learn so much about how things should be done sustainably by looking back to how people did things for centuries!
More like what people didn't do.
They didn't start fires wrecklessly nor did they attempt to put wildfires out.
They didn't have the option to put out wildfires, (any bigger than a small grassfire). They said "the natives embraced fires"... More like they didnt have the technology to if they wanted to or not
I do the same with my pubic hair. Works like a charm and it gets the unwanted pests

Please enlighten us with more details of how you do this.
Finally, people waking up.
Controlled fires may be the best way to go
The natives have known for at least thousands of years that controlled fire is the ONLY way to go.

if i'm not wrong, i watched a video, probably from it's okay to be smart channel, that there will be beatles & animals growth that feed on those burnt woods..i'm not sure whether those would be helpful or bad for better overall forest maintenance.
love this series, please keep going
What is the ratio of oxygen consumption to CÒ² consumption of older trees to younger growing trees? Also adding the feature of CO² release of these trees to the atmosphere?
Also another aspect that I have not yet heard anyone address is that:-
We have removed as "oil" carbon compounds that were in STORAGE. Yes STORAGE. And we have returned NONE! to storage. Thst is why so much of our efforts do not have full impact.
CONSEQUENTLY! Possibly what we really need to do is:-
CUT! Yes CUT! not burn; down some trees and use them in such a way that they remain as permanent storage once again for these carbon compounds.
You know, unfortunately for me I am always giving out free advice. Advice that they hire consultants for, So if anyone thinks I should receive some compensation for this. I am all in.
Plants PRODUCE oxygen.
@@garmancathotmailcom and consume it.
@@ttonAb2 No, well only if burned.
@@garmancathotmailcom Incorrect. Plants conduct respiration which releases CO2. During the nighttime when plants are not conducting photosynthesis they release CO2 through respiration. During the daytime they take in more CO2 than they released at night and during the day, meaning when they are growing fast they take in more CO2. As trees get older their growth slows and the rate of new carbon stored is much lower. Plants dont "Produce oxygen" they break the bonds on CO2 using the energy from the sun and store the energy in carbohydrates until they need to break those carbohydrates down for energy to live.
Australia’s been doing this all my life lol
Was it burned heavily last year because of that?
And it still failed
Yes but just because that happened once in 100yrs doesn't automatically make it a bad idea also I think the government cut back on back burns
@@magivkmeister6166 every now and they one of your rockets explode that doesn't mean you abandon the technology altogether does it?
Ground FUEL.... It just seems like a waste, why not make that fuel into pellets(on site-not new technology) wich could be burned for heating/energy generation...
I'd assume the ground fuel is low quality biomass, inconsistent or too much moisture, plus dirt & foliage and the resulting powdery pellets wouldn't burn well.
But if the fuel was fed into a truck mounted biochar stove, the smoke could be properly mixed with air to burn completely and the bio char could be spread back on the ground.
Not economically viable.
@@garmancathotmailcom I agree and would require more labour, but it might be viable if close to residential to avoid the smoke.
Very well presented
I learned a lot. Thank you for this
Awesome
Nice video.
Or logging, use it or loose it.
The two methods are very helpful when used together. Thin it and then do an under burn
If forests need controlled fires,how did those places get it before human got to settle?
Lightning strikes usually.
The forests dont need "controlled fires" they need fires. When fires happen more frequently they dont let as much fuel build up. We put out most fires from lightning strikes and human causes so the frequent fires turn into big high severity fires due to the build up of fuels because we put out the fires that would have been low/moderate intensity.
Did not explain: why not just PHYSICALLY remove the ground-fuel or excess trees or any of the 'bad stuff' , rather than just BURNING the 'bad stuff' away.
Maybe too labor intensive
Apart from removing the fuels some of the other reasons it’s done is it can lower the spread of pests and diseases, remove unwanted species, provides forage, gives nutrients to the soil, and can help promote the growth of plants and trees
Controled burns where looked down on by tree huggers. But then the fires last summer burnt down tree huggers soy latte shop, as well as the big gums
everything in life must be balanced and harmonious. that is the only way
Nice video, thank you.
Please do a follow up video exploring the carbon and long-term impact of prescribed vs high impact fires. My reason for asking- high impact fires sterilize the ground besides taking out all vegetation. In low intensity fire many species survive (above and below the ground), plus make many nutrients more Bio available, greatly reducing recovery time.
Also wrong. Some species need higher intensity fires to seed the land properly.
Also a lot of species of weeds prefer low intensity fires and will grow out of control because of low intensity burns.
@@VariantAEC Wow, your information is way different from anything I was ever taught. Fire is important to many species, but not the high intensity mega fires we're talking about.
@@carrdoug99
High intensity fires heat can reach higher tree canopies allowing them to dispense protected seeds whose outer hulls only open during these kinds of fires. Redwood and Sequoia trees need these kinds of fires.
This small fire here and there approach will cut down on dramatic and uncontrollable wildfires, but it's still not great for the forests.
Although, there are some some aspects to controlled fires, like for some plant/tree seeds to produce that way.
But that is probably not the only way they germinate, just faster that way.
And it is the only positive thing I can think of to controlled burning, besides reducing the spread of fires.
There is the other side of the story though, concerning our breathable air.
Adding to an already worsening air quality.
I don't know about that, I think there are better ways to deal with potential fire hazards.
Plus putting more smoke up in the atmosphere is a very bad idea.
Cutting and composting is a much better idea.
More environmentally intuitive.
More productive that way, and not counter productive, or detrimental to our health.
Controlled burning is the lazy way to dealing with it, the American way.
Cutting and composting will add nutrients to the soil, and improve our farmlands, and forests.
Making them more able to withstand fires when they come about.
I would say that controlled burns are OK in an emergency situation.
But should not be considered a standard rule for controlling our forests.
I wanna see timelapse on mushroom eating plastic
I'm very confused. We've been doing this in Australia for a long time. Indigenous communities have been using bushfires to hunt for literally tens of thousands of years. Even some animals are starting fires for hunting. Strange that it took so long for post-colony America to catch on.
Which animal does that? I am curious to know

Yes! sensible practices,Share this with friends. It seems we need to promote common sense these days not ignore or deny it.
Traditional in india tribes collect firewood from forests to keep it from burning.
Almost thought the thumbnail was Symbiote land or something
If people are opposed to prescribed fires because they don't like the smoke... they are very short-sighted.
You are not allowed to burn grass. 6:18 Oh Hood this is where you are. Maybe there is something in the blueberries they make muscle pain cure, but should explain all of it to everybody. I mean mayor or somebody - you better say truth or this is new era for Thaldraszus in the flames - this is street kings case you've built yourself to explore with Sandra in the The Lost City. What you were asking was some tree rendering quality, because on close up all the branches are 2D and trees weren't some randomly growing objects.
You can tell the difference immediately when hiking a well maintained forest vs a poorly managed one. You can’t hike in the dangerous forest, too much fuel
This is hands down the strangest fact I came across in 2021.
We need to cut down more trees and use the wood for building or in a away that locks up the wood for hundreds of years. The way the forests are managed now they are putting more CO2 in to the atmosphere than they are removing.

Look at how the Santa Cruz controlled burned turned out? This is too risky and not smart. Condoning such solutions is wreckless
Is this a metaphor for humans?
Indigenous people knows their environment. They have preserved their lands for colonisers to destroy.
Come on guys. We are fighting global warming not making global warming worse
You are now controlling forests like they are huge living things and now humans have to become the hunters to control excess growth, as wolves do deer. We are learning about the interlocking levels of living things on all scales. The very tiny and the very big both have optimum conditions that they need. If we interfere, WE have to become the "administrators", which requires knowledge that we do not yet have in many cases.

I don't get it.
Why would she be afraid?
Is it that her manner gave the feeling that she needed to apply boldness in the face of a resistance that in actual fact was not present and really non existent?
I am honestly trying to understand.
Great episode. Now, send this to the Democrats of California and change their mind about the controlled fires they refuse to allow
Of course you had to wrap up by tying it to climate change 🙄
yeah uh, idk fam seems like increased temperatures and drought risk in the coming decades are something worth mentioning when talking about forest fires?
@@Bogwedgle if the “big burn” happened in 1910 then a forest fire apparently can happen regardless of climate change. If the temperature gets hot enough to start fires, you won’t have to worry about it because we’ll all be gone. Fire is natures way of “cleaning”. If the temperature gets hot enough to rob trees of their moisture causing large piles of dead brush, then cleanup will be necessary and fire may be only way at that point. The current video however was about actually starting small fires in order to put off that future need of cleaning, which has little to nothing to do with climate change and instead they had to tie it all together in one sentence at the end to remind you it’s really an “alarm”. It was a dog whistle.
@@aaronburrell3729 Or, you know, maybe this really is a two factor problem. Hotter and dryer climate increases the risk of severe wildfires. Close to a century of forest mismanagement also does. Just like there are floods without heavy rainfall, there are wildfires without climate change. Which does not mean that heavy rainfall has nothing to do with floods.
Yes, they worked it in quite clumsily, like they talk about fallacious fire policy as a cause throughout the whole video and then suddendly go like "ya know, climate change increases risk of severe wildfires", but nonetheless: the message is that in the face of higher risk due to hotter, dryer climate, it is all the more urgent to change forest management accordingly.
Sounds like a climate change denier lmao
Roughly, forest climates can be categorized into three "fire-buckets": wet, borderline, and dry.
- Wet: too humid for forest fires. In that case, climate change won't increase the amount of fire.
- Borderline: can have forest fires, but most of biomass decomposition happens organically, rather than through fires. In that case, a drier climate will increase the amount of fire, while a wetter climate will decrease it.
- Dry: forest fires are the dominant decomposition mechanism. In that case, a drier climate will actually decrease the amount of fire, as it will lead to less biomass production.
Large parts of California forest fall into the third bucket... The relationship between climate change and forest fires is much less straightforward than we're made to believe.
Disclaimer: this is still an over-simplification. Notably, seasonal climate variability has been ignored.
Common sense.
