  •  I'm curious what you're basing this on. (8+ / 0-)
    I blame cats and coyotes.
    I suspect you're referring to mountain lions when you say cats and we don't have those here in Mo.( other than very rare strays that wander in every few years), but we have a healthy population of coyotes and bobcats and the beaver population is flourishing right alongside them. And there's also the fact that beavers were common throughout wilderness areas long before man decimated the predator populations. Just wondering if you'd seen evidence of it or just going on a hunch. I agree that beavers create fantastic habitat that benefits many species of wildlife.

    •  They've no other predator I know of, and when (4+ / 0-)

      introduced to new areas they flourish. Yet some places I see dams yet the next creek over nothing... Could be trapping. We don't' have wolves. I do know beaver are very susceptible to predation when on land chewing trees. In the water they're much safer. Might be why signs of chewing only seemed to occur at night.

      There's very little data for all species like this as it costs so much. I fund studies on lynx, mountain lions, elk, mule deer, jumping mice, and ferrets, but lately we've had to cut back  spending to meet budgets. Collaring it'self is pricey, and we try to keep a constant number of biologists on salary. People don't like to come work as contract workers as much. Some of the counties and municipalities have stepped up to fund coyote studies, but there's only so much to go around.
