Summary of 2011-2021 trap data for the endangered Morrison Creek lamprey (Lampetra richardsoni) / by Joy Wade. : Fs97-6/3469E-PDF

"This document describes sampling activities and summarizes results from 2011 to 2021 trapping surveys of Morison Creek Lamprey, a unique population of Western Brook Lamprey (Lampetra richardsoni). Morrison Creek Lamprey is an endangered species at risk, present only in the Morrison Creek watershed in Courtenay, British Columbia. The trapping activities reported here not only help to monitor the population, but have also provided an opportunity to identify conservation concerns and protect the species and its habitat. The data provided in this document shows persistence of the population within its range, and should not be used as an indicator of population abundance or relative abundance"--Abstract, page vi.
