Dragonfly and damselfly monitoring provides important data on freshwater habitat quality, with individual welfare linked to clean water and appropriate emergent vegetation.
Dragonfly larvae living in polluted water face physiological stress responses that impair development and survival. While insect sentience remains uncertain, the ecological welfare of freshwater invertebrate communities - representing billions of individual lives - is directly determined by water quality and habitat management. Garden ponds with appropriate planting and clean water support dragonfly breeding that contributes to landscape-scale population welfare.
