Dragonflies are variouslysensitive to both the health of freshwater systems and the quality ofvegetation along rivers and around ponds. Their wide range of sensitivitiesenables us to measure the extent to which freshwater ecosystems are eitherdeteriorating or are improving when we undertake restoration. After discussingdragonfly functional morphology and their diversity and distribution, the booklooks at a trait perspective on dragonfly conservation. It then examinesstressors on freshwater ecosystems and dragonflies, conservation action, andassessment and monitoring using dragonflies. It concludes with methods forfuture-proofing freshwaters and their dragonfly sentinels.
