Dr. Keith Somers is an aquatic ecologist, biostatistician
with the Dorset Environmental Science Centre of the Ontario Ministry of
the Environment. Keith has been working with colleagues to develop
simple but credible sampling protocols for the rapid bioassessment of
lakes and streams. The secret to the success of these protocols is due
to a focus on non-scientific volunteers. The protocols only require
order level taxonomic identifications for samples of 100 invertebrates,
which makes them particularly useful for lake and stream stakeholders!
Recent efforts have addressed the question of establishing benchmarks
for normal or background conditions. These benchmarks are then used to
evaluate the biological health of test lakes and streams. Keith has
co-authored over 25 scientific papers in a variety of freshwater
