Case Studies in Stream Habitat Rehabilitation
We had an interesting discussion Wednesday night because you each read some background papers and were ready and willing to share your thoughts. Thanks for showing me why you are here. Let me offer you a "thank-you prayer fish" (a central stoneroller Campostoma anomalum) for your efforts.
“The idea that the majority of students attend a university for an education independent of the degree and grades is a hypocrisy everyone is happier not to expose. Occasionally some students do arrive for an education but rote and mechanical nature of the institution soon converts them to a less idealic attitude”
- Robert M. Pirsig in Zen and the Art of Motorcycle Maintance
Next week we will discuss the results of studies that attempted to evaluate the success of stream rehabilitation techniques -- to learn what works and how "we" have operationalized standards and criteria for "success."
Everyone will prepare by reading the same paper by Phillip Roni et al. (2008) "Global review of physical and biological effectiveness of stream habitat rehabilitation techniques" and Ansaw Yaw e will lead the discussion. Everyone should read this one article and post a rhetorical precis; it is a long 24 pages not counting references but is quite comprehensive. This article brings together the very fragmented nature of the literatures on stream habitat rehabilitation. This paper is only available on Blackboard (and not on your CD).
There are many other readings available and we will split up the reading assignments later in anticipation of further discussions on September 24 (led by Brandon Peoples). So you should review the list of readings and decide about specific regions or rehabilitation techniques that you wish to investigate further.
In the first session I will lecture on microhabitat selection(theories and methods). I ask that you think about a stream you are familiar with and mentally bring one personally relevant example of the flora or fauna that exists there (or post a pic) so we can think about the issues of habitat selection in light of stream habitat management. Also, read the required reading on "Certainties and uncertainties in defining essential habitats for riverine smallmouth bass" and post a rhetorical precis on it. If you are morally opposed to (or just uninterested in) this species you may read about habitat selection in a stream salmonid or a mussel or a darter.
