Updates to the Massachusetts Endangered Species List
BOSTON — MassWildlife works to conserve biodiversity in the Commonwealth and updated the list of plants and animals officially protected by the Massachusetts Endangered Species Act (MESA) this year following an extensive review of population data and threats.
Following this update, there are now 453 native animals and plants listed under MESA. All listed species receive the same protection, but they are categorized as endangered, threatened, or of special concern—depending on their status and the threats they face. After analysis of scientific data and review of public comments on the proposed changes, 22 plants and animals were added to the MESA list, 1 plant was delisted, and the status of 2 plants was changed.
MESA is implemented by MassWildlife's Natural Heritage and Endangered Species Program. By law, the list of plants and animals protected under MESA must be reviewed at least every 5 years. The status of a species may change due to factors including changes to our knowledge about:
- Reproductive and population status and trends within the state,
- Species' habitat requirements and vulnerability to threats to its habitat,
- Geographic and genetic distribution within the state,
- Rarity of the species and its habitats, or
- Emerging diseases and infections
