Anthropogenic euthropication is suspected of being a problem in many British Columbia (BC) lakes. However, long-term limnological data are rare or unavailable for most lake systems, and so the natural pre-disturbance conditions of lakes, as well as the timing and magnitude of human-related changes, are unknown. This thesis explores the use of diatoms in paleolimnological analyses of BC lakes to elucidate long-term trends in eutrophication.
