The June 2014 map of Natural Diversity Data Base Areas for Woodstock CT Natural Diversity Database - Roseland Lakeindicates the existence of one or more species that are either State or Federally Listed, or a Significant Natural Community. The exact location has been buffered to produce a general location shown as a "blob."

In order to protect the species, the CT DEEP does not disclose the species name or exact location. However, if a project is within the shaded area, there may be a potential conflict with the listed species.

For more information, a Request for Natural Diversity Data Base State Listed Species Review form (DEP-APP-007) can be requested and submitted to the NDDB along with required maps and information about the project. The DEEP can then provide recommendations for avoiding impacts to the species. See www.ct.gov/deep/nddbrequest for more information.
