They're also ferociously devour trees; urban areas are less likely to be able to support that, e.g. see the penultimate paragraph of this section https://en.wikipedia.org/wiki/Beaver#Urban_beavers_in_United_States https://en.wikipedia.org/wiki/Beaver#Urban_beavers_in_United... in which a pair was reported to cut down $5 million in trees.

They also help preserve ecosystems even as they are destructive to human endeavors: http://www.santacruzsentinel.com/environment-and-nature/20141220/leave-it-to-beavers-california-joins-other-states-in-embracing-the-rodent http://www.santacruzsentinel.com/environment-and-nature/2014...

  Well, it's all an "in the right place" sort of thing. Put them just outside a human area with too low tree density and pretty much everyone loves beavers, aside from as I recall trout fishermen who better running water. However, when the article says "Beaver dams bestow benefits to the environment that we humans can’t easily copy. They turn land into a sponge for water.", that presupposes there being some water for them to actually capture and manage! Kind of a bricks without straw problem; hopefully the 2015 El Niño will give them and everyone else a lot of water to work with. This being modern, high tech California, surely there's an opening for a "Disrupt Drought!" modern version of this Idaho effort using the latest in drones et. al. ^_^

Beavers do not devour trees at random, the mostly kill dead or dying trees which is very important for the forest. Killer trees in areas that lost their beaver population are actually quite a big risk to humans.

    Agreed. Also from personal observation, they prefer young, tender saplings, though they do seem to do some sort of tradeoff calculus based on size of tree/distance to water (i.e., they'll take a bigger tree if it's right by the water, so they don't have to drag it as far). Given their choice, they appear to prefer two or three inch saplings, but I've seen them take six inchers if they happen to be right on the shore. The OP is right, though, that beavers do serve an important function in the ecological succession between from stream->pond->bog->meadow->forest.
