Proposed Plant Species of Greatest Conservation Need

New York's Wildlife Action Plan

The NYS Department of Environmental Conservation (DEC) is in the process of updating the New York State Wildlife Action Plan (SWAP). The SWAP assesses the health of the state's wildlife and habitats, identifies the problems they face and outlines the actions that are needed to conserve them over the long term. To initiate the 2025 update, DEC staff and conservation partners are reviewing the species status assessments (SSAs) from the 2015 SWAP, focusing on revising information on conservation status, population trends, and threats to these species. This information will be used to revise the Species of Greatest Conservation Need (SGCN) list. SGCN are species native to New York State that are currently experiencing threats likely to jeopardize the future of their population in New York if action is not taken within the next 10 years. More information on the NY SWAP and species status assessments for wildlife SGCN can be found on DEC's NY SWAP page.

The first draft plant SSAs for the 2025 SWAP are now available for public review and comment. Additional SSAs will be released for public review upon completion.

While plant species are not included under the current federal definition of SGCN and are not yet represented in the SWAP, the New York Natural Heritage Program has initiated an effort to identify plant species that may qualify for inclusion in the 2025 SWAP.

NYNHP has developed a draft list of 491 potential plant SGCN, based on species currently listed as threatened or endangered in New York, or ranked as S1 or S2.

All comments and input are due by June 17, 2024 and should include as much detail as possible supporting the designation of a plant species as a new SGCN. Science-driven information supported by data and references will greatly aid in creating robust SSAs and a relevant plant SGCN list for the 2025 SWAP.
