regaurdless of what was intended your downvote and reply shows a lack of good faith.
I suggest reading Candide by Voltaire, first published 266 years as a critique to the philosophy you are currently espousing.
People: "If God, then why bad?"[0]
Leibniz: "God and bad can coexist. E.g. we live in the best possible world."[1]
Voltaire: "Here's a depiction of some fictional bad."
I don't think Voltaire engaged meaningfully with Leibniz's argument. (I think that Leibniz is simply right tho, in the mathematical sense, so there isn't much room for Voltaire anyway.)[0] : https://en.wikipedia.org/wiki/Problem_of_evil

Moving a few wolfs, I would hardly call that effort! Stopping regulations and allowing some hunters in Yellowstone would have similar effects!
It is more like morons, who do not understand biology are in goverment! Overprotection allowed elk overpopulation!
Can other ecosystems do this? Or is Yellowstone the only one?
- intact enough to have quick bounce back behavior upon species reintroduction and
- small enough for you to have a good idea about which species are present
- come with a built-in control variable: the civilian space on the other side of the border represents what would have happened if we had let economics have its way with the land
Maybe you don't need quite that level of protection to see such effects, but generally you do need some. Throwing some wolves at a once-forest that's now half way to being a desert will not always save that forest.
"Gray wolves were reintroduced ... to help control the numbers of elk that were eating young trees"
- Elk quit loitering along streams, so willow and cottonwood shot up, anchoring soil and narrowing channels.
- The new woody growth gave beavers lumber; their colonies jumped from one in 1996 to a dozen within fifteen years, raising water tables and rebuilding wetlands.
- With healthier riparian zones came deeper pools, colder water, and a surge in native trout and song-bird nests.

However, the introduction of wolves did, incontrovertibly, add a system element that had not been present before. Exactly what that element was, and how it expressed is up for interpretation :-)
It also proves the worth of just simple studies over a long period of time. Science used to do a lot of that, and it was very interesting, as many appear on hacker news, but now it seems that cut-n-done grab more popular news.
It also bears the question: what longitudinal studies are popular here besides this one, and retro computing?
> The average height of willows in fenced and dammed plots 20 years after the initiation of the experiment exceeded 350 cm, while the height in controls averaged less than 180 cm
> This suggests that well watered plants could tolerate relatively heavy browsing. It also shows that the absence of engineering by beavers suppressed willow growth to a similar extent as did browsing
They posit that the growth in control groups not matching the fenced areas is evidence of wolves reintroduction not having the effects they are said to have. It is a pretty unconvincing argument since there are so many other variables involved. They also prove that IF the wolves have indirectly lead to either the return of beaver dams, or reduced elk browsing, there is undoubtedly an impact in tree growth, which is a positive result regardless.
Their theory that things will never return to their original state, and instead will settle into a new alternate equilibrium is probably correct, but does not seem like the definitive blow to the wolf theory that it’s made out to be.

TL;DR - the observed reduction of the elk herd correlated with wolf introduction, but also with an increase in cougars, grizzly bears, and even bison, all of which either reduce or compete with elk. Human hunting also added pressure, but that has been limited as the herd size reduced. It is complicated.

2,200,000 acres, with 100 wolves.
Then they've made the claim that those 100 wolves in 2.2million acres has resulted in plants and fish returning? As opposed to their efforts doing nothing at all?

That said, I believe wolves had a profound effect on the Yellowstone ecosystem, particularly on elk and deer populations. Before their reintroduction, those species had few natural predators beyond hunters, vehicles, bears, and the occasional mountain lion. The imbalance led to overgrazing and the spread of diseases like Chronic Wasting Disease (CWD) in elk.

The effect on quaking aspens in Pardo is also something we need to study long term. Are the two related?

After all, off in a democracy an expert expects to be paid by taxpayers to make decisions that affect the taxpayer the expert should be, at the very least, be able to explain himself in an intelligible manner.
Thats the bare minimum of expectations. I also expect the taxpayer funded expert to provided full access to his data, notes and analysis software.
Im considered an expert in thermodynamics, materials science and E&M. The people that pay me routinely don't understand what I'm working on, but they expect me to explain myself.

But the experts did explain themselves. They’ve published numerous studies on how small wolf populations impact the larger ecosystem.
It’s not even that hard to understand. Yes Yellowstone is large, but there are a finite number of elk herds and the wolves move to follow and prey upon the elk herds.
Wolf packs can kill 20 elk per year per wolf, there are 120 wolves inside the park and 500 immediately around the park wandering inside it and killing elk that wander outside.
At the peak there were 18k elk in the park and now the numbers are down to 2000. There’s plenty of evidence that the decline is a direct result of the wolves.
Controlling elk population has tons of 2nd and 3rd order effects which have also been well documented.

Many downvoted comments etc. ( and much thanks for explaining the population numbers!)

I’ll say that I’ve not read the article so if it’s in the article then I would rather you just point to that, rather than make this response.

They've studied it and came to these conclusions, yes. Have you studied it and come to different conclusions?

The reintroduction of wolves is associated with an immediate, steady, and durable decline in elk - i.e. pushed the ecosystem past an inflection point into a new equilibrium.

It’s an interesting question and this could be empirically tested if human hunting would be slowly reduced.

Without risk of harm, elk and deer linger near water. This tramples the shoreline. And they love eating noshing on (aspen) saplings. Over time, the shorelines become barren.
With the reintroduction of wolves, shorelines are no longer safe havens. Aspens have returned. With aspens, song birds have returned. Trees shade the water (eg streams), so fish are happier. Trees stabilize the top soil, reducing erosion, allows other plants to become reestablished.
I dimly recall beavers returned too.

Aha. I was mostly right (or hallucinating). Here's perplexity link for "impact of return of wolves to yellowstone".
https://www.perplexity.ai/search/impact-of-return-of-wolves-...
I learned about the birds returning because of the wolves while volunteering at Audubon. That linked summary doesn't go into those details.

Update: I should've read the OC first. My bad. TIL: (too many) bison also negatively impact riverbanks. I had thought (misremembered) that overall impact of bison was positive. Does Yellowstone need more cougars?
