NYSDEC’s updates to threatened species must go further to protect biodiversity
Riverkeeper supports the NYS DEC's proposed updates to the endangered, threatened, and special concern species list, particularly the addition of several fish species vital to the Hudson River ecosystem.

Without broader inclusion, these regulations risk overlooking species that are declining and need urgent protection to preserve New York's biodiversity.
