In response to Steve Hallstrom's message:
Most studies of riparian birds have been done when the riparian habitat is bordered by some sort of forest or woodland, so bird territories can be a little sloppy in such a situation. If a bird typically has a territory 500x500 ft, will it accept a 200-foot wide riparian strip with nothing beyond it? Or even a 400-foot wide strip? If there is nothing but clearcut on either side of a riparian strip, it will certainly be degraded as a habitat. However, I can't predict the outcome of a study to determine just which birds will accept these various-sized buffers, and it would be of great value, *especially* if it were done well.
There may be such studies already, but not that I've seen. There is so much in the "gray literature" now--government and consultant publications that aren't seen by most people--that something may exist, but if not, this would be a very valuable study. And of course there would have to be "controls" (riparian + intact conifer forest) for any such study.
I hope there's money to pay someone to conduct such a study (like maybe the amount Weyerhaueser employees spnd on lattes every month). I'm very concerned that more and more of this sort of work is done by well-meaning but inexperienced volunteers. Sometimes the money available that goes to "volunteer coordinators" should be used to pay professionals to do the work themselves!
