The intern will utilize Dragonfly Mercury Project Sampling Guide for the Collection of Dragonfly Larvae Samples from National Parks for Mercury Analysis (Nelson et al. 2017) guidance to connect citizen scientists to parks, advance the NPS educational mission, foster biodiversity discovery opportunities, and
provide baseline data to better understand the spatial distribution of mercury contamination in Glen Canyon National Recreation Area (GLCA). Mercury (Hg) is a globally distributed contaminant that can harm human and wildlife health. In its toxic methylated form, mercury builds up in aquatic and terrestrial food webs. Effects can include reproductive and neurological impairment. The intern will engage citizen scientists (i.e. students, visitors, youth conservation corps members) in collecting and processing dragonfly larvae.
