Summary of initial surveys at index stations for long-term monitoring of freshwater mussels in southwestern Ontario between 2007 and 2018 / by Margaret N. Sheldon, Kelly A. McNichols-O'Rourke, and Todd...: Fs97-4/3203E-PDF

"Between 2007 and 2018, Fisheries and Oceans Canada established 22 index stations as part of a long-term monitoring program for Ontario unionid populations. The objective of this program is to detect changes in the status of unionid populations, specifically Species at Risk, over time. Index stations were established across five watersheds in southwestern Ontario: 1) Saugeen River (four stations), 2) Maitland River (six stations), 3) Bayfield River (one station), 4) Grand River (seven stations), and 5) Thames River (four stations). Baseline data were collected through the completion of an initial quantitative quadrat survey at each station. These data form the foundation of the monitoring program to which future surveys will be compared. The monitoring program gathers invaluable long-term data on Ontario's unionid populations which can be used to guide and support conservation efforts and recovery strategies"--Abstract, page vii.
