Threats [-]
Seepage areas are key areas for this species for oviposition, and although there is little published information available citing specific cases of negative impacts to the various species of stream and seepage dwelling odonates, any activities which degrade the sensitive hydrology of these habitats would threaten populations of these species. The most important likely negative impacts would come from changes in the natural hydrology such as the building of dams, increases in the sediment load of the seepage or associated stream (such as might result should agricultural activities or logging occur down to the stream edge), changes in dissolved oxygen content, direct effects of pesticides, and chemical contamination by runoff of agricultural or other discharge.

Research Needs [-]
Research aimed at obtaining information on population size at occupied sites would be useful in determining the overall population for this species in the state. Research on larval lifespan would also add information useful in assessing population sizes.
