Saw that in Maine in the 90's with the spruce. The little buggers have been spotted again just over the border in Canada, so we're probably in for it again.

...sometimes it is easy to overlook the not so obvious...


The photos and news from the past month’s devastating fires across parts of the West—charred towns, dramatic helicopter rescues, apocalyptic skies—have provoked fear, anger, and an understandable search for blame. It’s clear that fires are getting worse. But why? Scientists point to a number of reasons. Hotter and drier conditions brought on by climate change can prime vegetation to burn, and decades of fire suppression have allowed fuel to accumulate in forests. Millions of people now live closer to those dry forests than ever. And then there is the matter of the beetles.
There are 600 species of bark beetles in the United States, and they’ve evolved with their various host trees over millennia. Many bark beetles infest already dead or dying trees, but some, like the mountain pine beetle, attack living ones. The mountain pine beetle alone has killed roughly 100,000 square miles of trees across western North America over the past 20 years, from New Mexico all the way up to northern British Columbia. Climate change has instigated this dramatic spread, by eliminating the cold spells that kill off the beetles and by leaving the trees stressed by drought, unable to defend themselves.
Sorry the beetles didn't set the trees on fire otherwise you wouldn't call them bark beetles, you'd call them pyro beetles or Antifa.
If the beetles are a problem in Cali then why didn't they take their multi million dollar home property taxes and spray the base of the trees where their eggs sit and hatch? Oh that's right, they can't even spray the sidewalk poo, what makes us think infestation of beetles is more important then hairdresser appointments.

You ever try to spray 100,000 acres of trees?? For my ASH beetle problem, I've got to do injections or insecticide every 2 years for maybe the next decade.. That's a lot of work for 16 trees.

Bark beetles DONT set trees on fire.. MAN, Lightning, and PGE lines coming down do...
It's insecticide now or fire retardant or water later according to the OP blaming beetles.
Yes that's a lot of work as is putting out fires if that can have volunteers then put the hippies to work and get them to save the forests and volunteer.
Lightening was to blame for the previous fires and maybe one recent but most others during this one were arsons.

I think it is easy to ignore the interrelatedness of the causes of these events. It isn’t just the initial spark, it is all the other factors that go into turning an easily managed fire to a thousands of acres devastation.

When tree killing insects spread, weakening and killing trees, you are lookIng at thousands of acres of dead wood.

But certain insects do strange things to trees...

Key Findings
  • Lodgepole pine (Pinus contorta) trees are chemically altered after mountain pine beetle (Dendroctonus ponderosae) attacks. Trees dry out rapidly during the red stage and are more flammable than unaffected trees.
  • Beetle attacks increase the emission rates of several highly flammable terpenes.
  • The flammability of yellow and red trees is higher than green trees because they have (1) shorter times to ignition, (2) lower temperatures at ignition, and (3) higher heat yields.
  • Needles of Engelmann spruce (Picea engelmannii) during the yellow stage of a spruce beetle (Dendroctonus rufipennis) attack contain less moisture and are more flammable than unattacked trees.
Fire managers and firefighters should be aware of the possibility of increased potential for crown fire initiation in beetle-affected stands as well as the prospect for rapid changes in fire behavior as fires move in and out of beetle-affected areas.

Healthy trees can usually withstand fire and limit both it’s spread and intensity. Affected trees, or worse, large amounts of dead forest plus overly dry conditions and winds turn it from manageable to out of control.

I don’t understand why people it’s just one thing leading to a forest fire.

As to the claim most were arson, that is simply untrue. Arson is the deliberate setting of a fire (and every fire is automatically investigated for possible arson), most are human caused, but accidental, not intentional.

What started the fires?
Many fires were started because of human causes, including most of the fires in California. The El Dorado Fire in Southern California’s San Bernardino County was started on September 5 by a pyrotechnic device at a gender-reveal party in El Dorado Ranch Park, just 80 miles outside Los Angeles. In Oregon, officials have opened an arson investigation into the Alameda Fire, which is responsible for multiple deaths and has destroyed hundreds of homes.

However, some of the fires, including the August Complex Fire, were caused by lightning strikes in extremely dry areas. Others in Oregon and California were started by downed power lines. Unusually strong winds in Oregon have helped spread the fires rapidly there while typical winds in California were made even worse by a sudden winter snowstorm in the Rocky Mountains, which sent cold air blasting into the Sierra and Cascade mountain ranges.

Multiple far-right and conspiracy websites have been spreading misinformation about the origin of the fires, on Facebook and YouTube especially. They claim, with absolutely no support, that they were set by members of antifa and Black Lives Matter. Websites the Gateway Pundit and the Post Millennial have claimed without evidence that Jeff Acord, a 36-year-old man arrested on charges of starting a fire in Washington, was an “antifa militant.” Many of the rumors have been amplified by self-professed QAnon supporters.


In my state, we are 78% forest. We have not seen forest fires such as have been engulfing the west. We have our share of flammable idiots and meth labs...but no devastating fires.

I am 7 miles from a state forest where I regularly hike my dogs. The paths are maintained And cleared, trail signage put up, and new shelters created largely by the fund raising and volunteer efforts of the “hippies” you disparage, because our state does not provide a lot of funding for park maintenance.

Brother in law and I picked up a load of blue pine tongue and groove yesterday. The wrapping said it was from sustainable forests. We assumed, because more trees were being killed by the pine beetle every day. Beautiful wood, nice grain with dramatic changes of color and with the holes and burrow markings of the beetle trails throughout each piece. What doesn't burn, makes great looking ceilings, walls and interior accent.

Sounds interesting, do have a picture?

Most people look for the simplest of answers. Especially conspiracy orientated folks who have ONE ANSWER to every problem.. Environmental problems almost NEVER have "one cause".. It's complex.. And in this case, the article is RIGHT ON..

GW is a convenient excuse to IGNORE all the other issues of wildfires. Just like we recently found that coral reefs with a human tourist footprint were dying because of a sunblock ingredient that is deadly in even MINUTE quantities.

MANY countries have similar forest/suburban interfaces like Cali.. And similar droughts and climate and yet THEY don't have our problems.. It's because there's a whole SCIENCE of forest mgt and wilderness mgt that has been tossed out the window because the govt orgs in charge have this imagined vision of NO HUMAN FOOTPRINT in the forests and wilderness.

In addition the things cited in your article, firetrails, fire breaks, infrastructure for forest mgt is BANNED as an option...

Here in Hillbilly Hollywood we have the scourge of Emerald Ash Borers,.. Was just told that ALL my ash trees need to be protected. I've got about 16 of them on the cleared part of my lot.. One already clearly dead -- a couple probably infected. It's gonna rip thru middle tennessee like a wildfire and in the next ten years -- unprotected ash trees will be very rare..

Exactly, this is a complex problem with many cause all interrelated, and Climate Change is but one part of it...to simplify it...it only takes a few degrees to change the level of annual insect die-off from sustainable by the trees to unsustainable. We are only beginning to understand how complex this is. Plus, we are realizing that fire IS a part of the natural ecology, BUT not the types of fires we are seeing now, so intense they kill everything.

The ash borer sounds bad...here, we are dealing with the Hemlock Wooly Adelgid, which is affecting huge swaths of hemlock...no cure but they can treat it every 5 years with pellets.

Roadless ACT.............DNC laws will not even allow the forestry dept to build a road let alone a fire break.

Forcing rotting wood to lay on the ground and not burned off attracts bugs........beetles.....

Overgrown trees not thinned kill trees and bugs...........beetles love to eat dead trees...
...

Many forestry management people like to cut down trees and leave them in piles while thinning the forests..........so the beetles will come into this delicious pile of dead wood and feed.............to be then burned later in a controlled burn.

Decades worth of mismanagement and idiotic laws and Acts have caused this..........and now the left goes........WOW.........I COULD HAVE HAD A V-8

I would challenge that a bit. The insects that break down dead wood into humus are not necessarily the same insects that attack living wood. In addition dead would provides valuable habitat and nutrients to the overall forest ecology. The problem arises when you have huge amounts of dead wood, acres of trees killed off by insects, and dry conditions...

I do think controlled burns are necessary, but it isn’t only regulations that are problematic...it is complicated by the spread of humanity into previously wild areas, so more homes to worry about and by the allocation of resources that may well be tied up in fighting uncontrolled fires.

Reducing the risk of wildfire

Since the inception of the National Fire Plan in 2001, the BLM's hazardous fuels reduction and forest rehabilitation activities have been guided by the National Fire Plan's goals. These goals include: to reduce fuels (combustible forest materials) in forests and rangelands at risk, especially near communities; to rehabilitate and restore fire-damaged ecosystems; and to work with local residents to reduce fire risk and improve fire protection.

The National Fire Plan is being successfully implemented under the leadership of an interagency and intergovernmental group of local, state, and Federal agencies (including the BLM) working cooperatively to reduce wildfire risk and restore fire-adapted ecosystems. In Oregon and Washington states, the emphasis for hazardous fuel treatments (which may include a thinning component) is in areas east of the Cascade Mountain Range and in southwestern Oregon where concentrations of hazardous fuels are greatest and there is a high percent of WUI adjacent to federally managed land. With a focus in these areas, since 2001, the BLM has applied nearly 674,000 acres of hazardous fuels reduction treatments to woodlands, rangelands, and forests on the public lands in Oregon and Washington. Roughly 48 percent of the acres treated in OR/WA between 2003 and 2007 moved to a better condition class.

Restoring Forest Health

Thinning is used in forest restoration projects to reduce tree stocking levels and fuel loading of overstocked stands. A goal of forest restoration is increased forest resiliency to insect, disease and stand-replacing wildfire. Treatments are designed to leave in place species of trees that are more adapted to the forest ecosystem, including those where periodic ground fire is a normal disturbance. Many treatments in woodland vegetation have an additional benefit of improving watershed conditions, wildlife habitat, and species diversity.


Thinning the forest for a healthy forest.........you can't do that when you put loggers out of business......Create the Roadless Act so the Forestry service can't even build a road..........LET ALONE build a fire break.....

Decades of mismanagement have caused this to be an INFERNO....and now the left wants to blame it on anything but THEIR OWN POLICIES that have made this a disaster.

In Oregon the Portland idiots are doing the same thing done in California.......trying to put the loggers out of business.

Why not deforest?
 
In Oregon.........leftist MOON BATS think it will work this time.........Want to be like California.......put the loggers out of business with their policies.......decade down the road.........then they will wonder why the forest EXPLODE as they run out of business the loggers there WHO ARE ESSENTIAL TO FOREST THINNING.

Same thing as California............just move to another state to screw it up also.



Stupidity in motion.
 
This isn't rocket science folks...........it's common sense logic.

Here.........a simple video that explains it well.......

 


According to a Reason Foundation study, another flaw in forest management is a systematic reduction in timber removal. This began in 1990 when the spotted owl was listed as threatened under the Endangered Species Act. In response, the Forest Service placed restrictions on timber harvests. Additionally, President Bill Clinton introduced a rule that restricted the construction of new roads on 49 million acres of national forest. This limited the ability of the Forest Service from thinning trees. In 1993, 1,797,574 acres of wildlands burned, but in 2017 this number jumped to 10,026,086 acres.

From 1960 to 1990, 10.3 billion board feet of timber were removed from federal forest land each year. From 1991 to 2000 that numbered dropped to 2.1 billion board feet of timber per year.

“There’s an old adage that excess timber comes out of the forest one way or the other. It’s either carried out, or it burns out,” McClintock said in a speech supporting The Resilient Federal Forest Act, a bill that stops the practice of taking fire prevention funds to pay for fire suppression. It also streamlines environmental reviews so that forest managers don’t have to fill out hundreds of pages of documents just to cut down rotting and diseased trees. As of November 2017, this bill was still under consideration in the Senate.


When trees are too close together, they fight for resources. Many of the trees are weakened and become more susceptible to disease and insect infestation. These conditions turn entire forests into tinder boxes. A 2017 report from the U.S. Department of Agriculture (USDA) states that 129 million trees have died in California’s forests since 2010. The USDA report agrees with Trump — California’s forests suffer from neglect and mismanagement.

In order to cut down trees on private land, property owners must fill out a Timber Harvest Plan and get permission from CAL FIRE, said Schori. As of 1995, the private sector owned 8 million acres of undeveloped fire prone land, according to the California Department of Forestry and Fire Protection. Yet Timber Harvest Plans were only granted for 3,282,950 acres of privately owned land in 2017.

Air quality control laws also make it difficult for factories and private landowners to dispose of deadwood. The difficulty these regulations impose may prohibit private owners from effectively managing their land.

To prevent fires, both the California’s state government and the federal government need to deregulate logging and encourage the Forest Service to make a profit by selling timber. Until the environmental protests of the 1970s, the Forest Service was one of the only departments in the federal government making a profit. It is a myth that environmental concerns and business interests are always at odds. In the case of California’s forests, thinning the trees is in the interests of both parties. Trump understands this, and his administration is expanding timber sales on federal land.



Leftist policies caused this............this article shows it...................shows how timber companies are only 20% of what they used to be.............Same thing is happening in Oregon.........where leftist fled to avoid the high costs of California ONLY TO REPEAT again what happened in California.

You CAN'T BURN DOWN BRUSH..............LOGGERS GET OUT.........then your forest becomes dense......Trees become UNHEALTHY.........then they rot..............and get BUG INFESTED.............

Then THE WHOLE STATE BURNS DOWN...........and they wonder why..........LOL

LEARN OR BURN CALI
 


Man has caused it ..................Nature used to deal with it without man.......because the fires controlled the underbrush

I know about the beetle problem, I had this conversation weeks ago, but these fires were 4 out of 5 arsons by people with bad parents. What are you doing to address absantee parents (who don't know what their kids are doing or who they are associating with) instead of absantee ballots.
 
The mountain pine beetle alone has killed roughly 100,000 square miles of trees across western North America over the past 20 years, …
I don't believe a word of this nonsense. It's the whole ignorant male lumberjack stereotype exemplified, except in this case it's a lady screaming "Eek! There's a nasty bug in the woods!" and she's compelled to cut her hair because she got a little tree pitch in it or something.

Climate change has instigated this dramatic spread, by eliminating the cold spells that kill off the beetles and by leaving the trees stressed by drought, unable to defend themselves.
Yea, it has nothing to do with your Antifa friends:

Sadly no...debunked conspiracy theory.


Oh, so like Russian Collusion then?

Oh, and show us where the reports of democrat terrorists in Oregon setting fires has been "debunked?" I think you just made that up - Communists have no integrity.
 
...sometimes it is easy to overlook the not so obvious...


The photos and news from the past month’s devastating fires across parts of the West—charred towns, dramatic helicopter rescues, apocalyptic skies—have provoked fear, anger, and an understandable search for blame. It’s clear that fires are getting worse. But why? Scientists point to a number of reasons. Hotter and drier conditions brought on by climate change can prime vegetation to burn, and decades of fire suppression have allowed fuel to accumulate in forests. Millions of people now live closer to those dry forests than ever. And then there is the matter of the beetles.
There are 600 species of bark beetles in the United States, and they’ve evolved with their various host trees over millennia.

Most people look for the simplest of answers. Especially conspiracy orientated folks who have ONE ANSWER to every problem.. Environmental problems almost NEVER have "one cause".. It's complex.. And in this case, the article is RIGHT ON..

GW is a convenient excuse to IGNORE all the other issues of wildfires. Just like we recently found that coral reefs with a human tourist footprint were dying because of a sunblock ingredient that is deadly in even MINUTE quantities.

MANY countries have similar forest/suburban interfaces like Cali.. And similar droughts and climate and yet THEY don't have our problems.. It's because there's a whole SCIENCE of forest mgt and wilderness mgt that has been tossed out the window because the govt orgs in charge have this imagined vision of NO HUMAN FOOTPRINT in the forests and wilderness.

In addition the things cited in your article, firetrails, fire breaks, infrastructure for forest mgt is BANNED as an option...

Here in Hillbilly Hollywood we have the scourge of Emerald Ash Borers,.. Was just told that ALL my ash trees need to be protected. I've got about 16 of them on the cleared part of my lot.. One already clearly dead -- a couple probably infected. It's gonna rip thru middle tennessee like a wildfire and in the next ten years -- unprotected ash trees will be very rare..


Good lord, Ash are weed trees. You welcome to the ones that pop up all over my yard.
