Dragonflies as a Bio-indicator of Water Health

Dragonflies as a Bio-indicator of Water Health - Watersheds Canada – Work, Live & Play in Healthy Lakes and Rivers

Biomonitoring involves surveying macroinvertebrates (often the larval form of insects) that are sensitive to environmental changes, immobile, and widespread. Such traits allow these creatures to integrate and represent long-term water quality changes more effectively. This blog post centers on one important bio-indicator: dragonflies! It tells of the important roles they play in freshwater ecosystems and in our monitoring activities.
