Cal-NEMO provides comprehensive information on introduced marine and estuarine invertebrates and algae in California. The database contains everything from brief overviews of species and taxonomic groups to detailed records on the history of spread. The creation of NEMESIS and Cal-NEMO has involved years of research and literature review, and remains an ongoing project. Records are updated as new species are reported and new research is available.

The National CAPS Committee will revise the National Pest Surveillance Guidelines when annually reviewing the policy, strategy, and performance of the CAPS program. The NCC also will approve annually a “Priority Pest List.” This list will include the Commodity and Taxonomic Survey Pests, as well as Pests of Economic and Environmental Importance (OPEP Prioritized List). The Priority Pest List will be based on input by PPQ, the States, Center for Plant Health Science and Technology (CPHST), National Identification Services (NIS), and commodity organizations.

The Chesapeake Bay Database project ended in 2020. This site will remain available for historical reference, but the database has not been updated since 2020 and will not receive any further updates. See more information in the project overview. For up to date information on introduced marine and estuarine invertebrates and algae in Chesapeake Bay, please visit the NEMESIS North American database.
