Morrison Creek Lamprey (Lampetra richardsoni) trapping survey, June 2017 / by Joy Wade, Lindsay Dealy, Vanessa Hodes and Sean MacConnachie. : Fs97-4/3183E-PDF
"Passive downstream traps were placed in the main stem and headwaters of Morrison Creek, Courtenay, BC as a part of ongoing monitoring of Morrison Creek Lamprey, a federally-listed endangered lamprey species found only in the Morrison Creek watershed. The total numbers of lamprey trapped were low; however, they are comparable to the results of other trapping studies since 2011. Although methods are the same, catches remain much lower than those reported in the late 1970s and 1980s when the population was discovered. The causes of this decline in catch are unknown. Recommendations are to continue monitoring the population both in the main stem and headwaters through trapping studies and, using our best knowledge, ensure the habitat is maintained in a manner which supports the functions of the population and mitigates the effects of harm"--Abstract, page v.
