macroinvertebrates

Review the Freshwater Macroinvertebrates protocol and review the Freshwater Macroinvertebrate Habitat Type Field Guides to select the appropriate sampling method for these six habitat types: rocky substrate, multi-habitat, submersed vegetation, vegetative banks or around snags, logs or roots, muddy bottom, or gravel and sand. Sort macroinvertebrates into taxonomic groups by following the sorting, identifying, and counting macroinvertebrates Field Guide. In cases where there are abundant organisms, the sub-sampling  Field Guide is an option. 

mosquito-larvae

Review the Mosquito Larvae – Using the GLOBE Observer Mosquito Habitat Mapper App information, including how to collect, sort, identify, and count the number of mosquito larvae, and determine whether your specimens represent taxa that potentially transmit disease. Support community health initiatives by eradicating breeding sites in containers in your community. Learn how to report your data to the GLOBE website and visualize data using GLOBE’s Visualization System. Additional training:
