Sort of.
It is very hard to get a solid piece of Al to ignite in temperatures seen in forrsy fires.
In Uni, we used to make bombs from Al powder and an oxygenator. They made a big bang and a lot of smoke.

Here the few rabbits are skittish. The deer, there are many black tailed deer, will let you get within a couple metres. No crows, but a few Raven. No coyotes but bears, and maybe a few wolves at the north end of the island.
Cougars are the usuall cause of missing dogs and cats. We get them occasionally.

I dunno... I recall pictures from the Ft. McMurray fire that showed four aluminum puddles where the rims of a pickup truck once were. I doubt aluminum siding would fare any better. Aluminum may not burn at forest fire temperatures but it does melt.

The point not being that Al won’t burn/melt. But if a burning ember falls on it, it will not start the fire. For Al to go up everything around it is too late.

Dam, I almost forgot the coyotes in AZ and had my mind more towards the Javelina wild boars. Interesting that location makes huge differences in what to watch for during a hike. In recent years, grizzlies and black bear have shown up closer to town than ever before. Usually down by the river, 2 1/2 miles south of town.
Wild, once domesicated hogs, are becoming a serious problem in some places. Alberta i understand is a leader.

Ash cloud?
That is big.
Long term (June end) wind forecasts say some rain and wind on Atlantic seaboard and Montreal.
Did not check for other areas.
Might bring relief.

Huge country
Large forested areas
Low population density
Limited resources

These pictures are from my house in south Florida during the fires in Africa back in May of 2007. Both were taken on an otherwise cloudless day. The first shows the sun in the east at about 9:30 AM. The second shows the sun in the west in late afternoon a day and a half later. The sun is the tiny pale dot between the two power lines to the left of the pole. This stinky period lasted two days and had already crossed the Atlantic Ocean.
I am reminded of an old song by Three Dog Night:
… Before the breathin' air is gone
Before the sun is just a bright spot in the night-time
Out where the rivers like to run
I stand alone and take back somethin' worth rememberin'

I hope that once these fires burn themselves out (it could be years until the cycle breaks) the forests can grow back strong. We need more trees and less wildfires.
Or maybe this is a big tipping point, where oxygen content goes down and CO2 goes way up. I hope not. These ratios are not constant when we look back in time.

They are an issue. However, I've seen some news stories based on information provided by a prof at the University of Saskatchewan which imply that they're huge and overrunning the countryside which is not true. His numbers are distorted and misleading.
Last year I witnessed the biggest forest fire in this part of the Mediterranean. For the first time, people had to leave their homes and literally run away, my wife's relatives fled by boat because that was the only way possible. Fortunately, not many homes were destroyed and there were no casualties. The damage is still huge and it will take years until nature regenerates again, the olive tree is the most resistant and a new tree will emerge from the burned stump, but the vineyards are permanently damaged.
There are two reasons, global warming and people don't cultivate their fields that were under olives and vines for centuries(now they live in cities or no longer engage in agriculture because it is not profitable). Instead of those fields, there is now a pine forest or Mediterranean maquis, which is ideal fuel for fires in combination with strong winds.Last year was also the worst drought since I can remember, in six months we had maybe a dozen rainy days, so all the prerequisites for a perfect fire were present.
This year is different again, it's raining constantly, while in some parts of the Mediterranean it's drier again like last year.
All in all, we are to blame, no one else, just like the old proverb says; As you sow, so shall you reap.
We literally sowed the seeds of destruction and now we can only watch.

Not much by the looks of it. 2016 appears to be a benign year, yet there was a particulally devastating wildfire that destoyed much of Fort McMurray. https://en.wikipedia.org/wiki/2016_Fort_McMurray_wildfire

It's crap. I was interested enough to go to the source. They admit that it's inconsistent regarding both data source and time.
