Why This Matters in Lakeville
MESA, the definition of "Take," Priority Habitat, and the live public-comment period.
What Is Known
"Take" and Priority Habitat review
M.G.L. c.131A and 321 CMR 10.00 prohibit unauthorized "Take" of state-listed species. For animals, "Take" includes disruption of nesting, breeding, feeding, or migratory activity, which MassWildlife explains can result from habitat modification, degradation, or destruction. Projects in mapped Priority Habitat are subject to NHESP review absent an exemption.
