Fish and Wildlife - Endangered and Threatened Species and Migratory Birds - Regulations, Lists, Petitions, Essential Habitats, and Takings
SB 431 updates Maryland's rules for protecting endangered and threatened species and migratory birds. The bill requires the Secretary of Natural Resources to review and update species protection regulations by July 1, 2033, and every 10 years after that. It defines "harm" to include significant habitat changes that affect fish behavior, and clarifies that "take" means actions like hunting, trapping, or collecting. The bill also requires more detailed information in petitions to remove species from protection lists and allows for designating essential habitats for threatened species. These changes aim to strengthen species protection with clearer regulatory standards for state agencies.
