Anyone know of any studies that document beaver response to complete dam removal. More specifically, I am looking for information that suggests what factors, other than sheer stubbornness, that determine whether beaver tend to just keep replacing the dam or disappear to parts unknown for 6 or more months before returning.

I've had many beaver jobs over the years,and have noted that when a dam is completely removed and there is a colony there thay will stay!Sometimes with a single beaver you can get him to move on if it is a drastic water level change but they come back eventually.There arent too many places that I can think where it has worked.

I guess my uncle did some study on this . He took dynamite to the dam and house over and over . Samething happened they just put it back over and over . Finally just got a trapper to remove the 7 beaver and that worked .
