Between 2009 and 2018, scientists conducted a national scale assessment of mercury accumulation in the National Park System using dragonfly larvae as biosentinels (species that accumulate a pollutant in their tissues as an index of exposure to other organisms without significant adverse effects to the biosentinel) through a citizen science network called the Dragonf
