There are 599 species (amphibians, birds, fish, invertebrates, mammals, plants, and reptiles) in Connecticut listed as threatened, endangered, or of special concern.  At least one hundred of those species are believed to exist in Windham County, but not necessarily in Woodstock.  A thorough investigation of all sections of Woodstock has not been conducted; therefore additional listed species may exist in town.

The following species list is based on the most recent information available concerning designated endangered, threatened or of special concern in Windham County. 


  • "Endangered Species" (E) means any native species documented by biological research and inventory to be in danger of extirpation throughout all or a significant portion of its range within the state and to have no more than five occurrences in the state, and any species determined to be an "endangered species" pursuant to the federal Endangered Species Act.
  • "Threatened Species" (T) means any native species documented by biological research and inventory to be likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range within the sate and to have no more than nine occurrences in the state, and any species determined to be a "threatened species" pursuant to the federal Endangered Species Act, except for such species determined to be endangered by the Commissioner in accordance with section 4 of this act.
  • Species of Special Concern" (SC) means any native plant species or any native nonharvested wildlife species documented by scientific research and inventory to have a naturally restricted range or habitat in the state, to be at a low population level, to be in such high demand by man that its unregulated taking would be detrimental to the conservation of its population or has been extirpated from the state.

This list is excerpted from Appendix C of A Plan of Open Space and Conservation.  For more information, and the entire list of regulated species, see the State of Connecticut Department of Environmental Protection website on Connecticut's Endangered Species. A PDF file of regulated species for Windham County is also available.
