Which they never will on their own, so surely conservation regulations need to be enforced, too bad the US is moving backwards right now in that regard

Then you get people (understandably) upset that just about any work they want to do to improve their own private land needs to involve the EPA and/or a local wildlife commission.

The modern phrasing of "improve" and "develop" for destroy is pretty upsetting to me.

My environment was improved to an unliveable asphalt/gravel sprawl from edge of city with woods with frog and birdsong...

The temperature is cooler? That can't possibly be the only reason to explain such a dramatic change in survival rates. We definitely need more research on this topic.

If you do even a moment of reading about salmon, you will find that they are extremely sensitive to warm temperatures. Even a couple degrees F above their "normal" will allow disease to run rampant.

If you don't want to deal with swampy land full of beavers, don't buy swampy land full of beavers.

They should of done a better job purchasing land.

Maybe I missed it, why didn't they just reintroduce beavers?

Because the government makes the water that comes with them a huge liability.

Tons of vacant land owners would be happy to allow beavers and everything else if not for the fact that it destroys any prospect of doing anything on the land.

Everything you do to waste land area by "lightly" touching it further increases sprawl because it increases the land required to do things.

Environmentalism is in direct conflict with densely packing "stuff" onto land whether that's people or industry. If you want to preserve nature embrace the "concrete jungle" and the density it brings.

Look at historical small towns vs modern build outs of the same population. Despite building maybe four stories high at most 50k people in some New England or Midwest mill town fit on a tiny fraction of the developed area of the same modern population simply because environmentalists weren't around to mandate engineered drainage ditches and green spaces and setbacks and require every podunk business have fire lanes a drunk could back a lowboy into and all planters in their parking lot and the other stuff

I give the salmon a little more credit because the entire river can't be a beaver dam. That's their theory and I think will more research we're going to learn more about what's happening here.

Beavers can be incredibly difficult to live alongside of. My parents have 100+ acres of bush in central Alberta. When they bought the property it was logged out and mostly in a bad abused state and mostly dry. Over a few years, beavers moved in and transformed a formerly semi-marshy spot into a full pond. And then another. And another. Eventually though, without a lot of predators around (there's some skittish bears,…

Throw in some wolves and create a brand new set of problems :)

What are the problems actually? That they have improved water retention and soil hydration?

what's wrong with it not reverting to nature when they pass? people put flowers on loved ones graves.
