Climate change was the spark, invasive grasses were the tinderwood in Maui.

https://www.smithsonianmag.com/smart-news/how-swaths-of-invasive-grass-made-mauis-fires-so-devastating-180982729/

Pretty simple actually... after more than 2 centuries of sugar/pineapple plantations using the land around Lahaina... the land was abandoned and allowed to become a dense tangle of invasive grasses... combine the wet winter with a summer drought and add in a dash of hurricane force winds and POOF big fire.

WHO is responsible for land management there? Evidently need to clean things up...

For nearly 200 years, Hawaii’s economy was highly dependent on sugar cane and pineapple agriculture. But plantations began declining in the 1990s as the state transitioned to a tourism-dominated economy, report Simon Romero and Serge F. Kovaleski for the New York Times. Vast swaths of farming acreage were abandoned, and in 2016, Hawaii’s last sugar cane plantation shuttered.

Without farmers tending that land, nonnative brushes such as guinea grass, molasses grass and buffel grass moved in. These species are native to Africa and were introduced to Hawaii in the late 18th century by European ranchers who wanted a steady supply of drought-resistant livestock forage. Today, almost a quarter of Hawaii’s land cover consists of these invasive shrubs. They run amok on the tens of thousands of acres of plantations on which sugar cane and pineapple plants once flourished. Hardy, voracious and opportunistic, they invade roadside shoulders and encroach on urban housing areas.

“Those fire-prone invasive species fill in any gaps anywhere else—roadsides, in between communities, in between people’s homes, all over the place,” Elizabeth Pickett, co-executive director of the Hawaii Wildfire Management Organization, tells Wired’s Matt Simon.

1. Had they not been transplanted on purpose, there'd be other invasive species.

Some of the dominant problem invasive grass species in AZ were carried on horses and hay.

MIL was adamant about trying to eradicate it from the territory she and my FIL had jurisdiction over (an arboretum, they were curators), but it was pointless. The only reason she was adamant about eradicating them locally was to protect the arboretum. Birds also carried the seeds.

Early introduction or late introduction, they'd have spread quickly.

2. I think the main point of the article...

Is that land management failure played a BIG part in the blaze.

3. But land management doesn't pay ever-growing quarterly dividends . . .

Hence the general lack of interest in, y'know, trying to fix things.

Who owns the land?

If Dole ran a pineapple plantation for 100 years... and still owns the land, it's on them.

If it was a long term lease and it's State land, the State is on the hook.

Either way, State regulatory agencies dropped the ball.

Evidently, environmentalists had been warning of this for years...

5. Evidence points to winds downing power lines as sparking the fire.

A Lahaina resident has video of that happening. There's already lawsuits filed against the electric company. Power should have been cut off to the lines as soon as high winds kicked up, like we do here in CA. Hawaii Electric, which operates on Maui through its subsidiary, Maui Electric, is tiny compared with the Californian utilities that have paid huge wildfire settlements. Its revenue last year totaled $3.7 billion, compared with $21.7 billion at Pacific Gas and Electric of California. The lawsuits could easily bankrupt it.

6. BUt it could have been lightning... or a cigarette butt

It's the lack of land regulation that shoulders most of the blame. IMHO.

Who owns the land? If it's Dole... and they abandoned the land after shuttering farm operations... they're still responsible for upkeep.

If it's State land... they need to manage it.

Either way, a State regulatory agency needs to watch over it.

Just like here in California... we have an agency enforcing weed/brush/wood management

The article goes into greater depth.

9. You can cut grass, but not eliminate it. That's why you need to address ignition sources.

That's why in CA we cut power to lines during high wind storms in fire prone areas.

11. Clearing brush around homes would not have prevented this conflagration.

It was already a fire tornado when it reached homes. It was going "1 mile a minute." https://www.cnn.com/us/live-news/hawaii-maui-wildfires-08-13-23/index.html
