Mocha Emerald
Somatochlora linearis (Hagen, 1861)
Insects

Threats [-]
Any activity that might lead to water contamination or the alteration of natural hydrology could impact Mocha Emeralds and other stream dwelling odonates (Holst 2005). Such threats might include chemical contamination from agricultural run-off, changes in dissolved oxygen content, flow alteration, increases in sediment load, development near their habitats, and the building of dams (Natural Heritage Endangered Species Program 2003, Holst 2005).

Conservation Strategies and Management Practices [-]
Any measures to reduce water contamination or hydrological alteration such as agricultural run-off, upland development, and damming that would affect flow of small forested streams should be considered when managing for this species (Holst 2005).

Research Needs [-]
Further research is needed to define the distribution and population size of the Mocha Emerald. In addition, research is required to understand the habitat requirements and threats to this species, and to create appropriate management guidelines for its persistence in known locations (Holst 2005).
