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.

There's more food, less energy wasted fighting excessively strong current, and more places to hide from predators. Water quality goes up downstream of a beaver(-ish) dam.

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...

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. Des…

High density development leaving as much pristine nature as possible is vastly superior to sprawl for the environment, but the comment you replied to didn't seem to describe a density issue.

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 :)

That's the beauty of it. When wintertime rolls around they simply freeze to death.

TFA implies the issue is land owners won’t allow it: > But beavers can only thrive if landowners allow them to.

Why are you wanting transform the beavers property?

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

They will continue to breed, expanding territory unless there are predators. When they come across a culvert (or bridge), they will block it, eventually overtopping roads and washing them out.

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.

Ignoring externalities remains popular. We live in a society. I can’t build a helipad on my roof in the middle of Seattle. Technically that’s a limitation on my personal liberty. We accept it because of the cost to the people around me.

Unfortunately it seems like considering the cost to those around you is becoming a dying art

The two meanings are not synonymous. One can certainly destroy land through improving or developing it, one can also do improve it responsibly and minimally.

Building one or two small permanent structures on many acres of forest is not destroying it by a long shot.

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.

This is the opposite of a useful perspective.

Someone, definitionally, owns all the privately held land in the US. Large landowners in rural areas are on average more politically connected and wield more political power in their communities.

Telling them that any sort of work on their own land—no matter how small—requires extensive oversight might be well-intentioned but pisses off a lot of people who will then become bitter opponents of even well-designed environmental legislation. Telling them they should have made better purchasing decisions just motivates them even further.

What actually ends up happening is these people then do it anyway with zero oversight, because the amount of land involved is too vast to enforce these things on. You also get large concerted efforts to overturn any and all environmental protection.
