Welcome to the Denison Pequotsepos Nature Center

For 70 years, we have provided visitors and the greater Mystic community the opportunity to experience nature first hand, whether it be on the 10 miles of trails on land owned by the Denison Homestead and Avalonia Land Conservancy, in our natural history museum, our Nature Store, or as part of one of our many programs. The creation of the Coogan Farm Nature and Heritage Center in 2013 has added additional layers of education, history, and ecology to our offerings.

Our mission is to inspire an understanding of the natural world and ourselves as part of it – past, present and future. It is our hope that through DPNC and Coogan Farm that we will help our visitors foster a personal environmental ethic.

Come along with us as we ‘Celebrate 70′


We are busy at the Nature Center, no matter what time of year it is! Whether it’s educational programs, school outreach, a call to pick up an injured raptor or leading a walk across the Pequotsepos Brook to the Coogan Farm, we have a lot on our plates! We know that 2016 will be even more action-packed, as we embark on a yearlong ‘Celebrate 70’ campaign to mark our 70th anniversary.

On April 25, 1946, a group gathered to officially create The Pequot-sepos Wildlife Sanctuary. Originally envisioned by a local environmental champion, Adele Erisman (1909-2014) at a Mystic Garden Club presentation, the purpose of this new organization would be to “encourage the study and love of Nature by acquiring, developing and maintaining a bird and wildlife sanctuary and a museum and library … by holding classes, exhibits or lectures; issuing publications, and by any other means approved by the Trustees.” The beautiful and diverse Denison Society land was identified as a perfect location, and an enduring partnership was formed that continues to this day.

We will mark this milestone year through special events and programs, (including a few parties!) that will cover the gamut of the Center’s past, present and future— what the Nature Center means to each of us and to the community at large. Stay tuned to our Facebook page and our website as details are finalized on everything from a ‘Moth Ball’  to a retrospective of our Natural History Calendar artwork and a ‘Farmers to Owls’ trail run.

Do you have a 70th birthday in 2016? Were you or a family member among our original founders or long-term members? Perhaps you’d like to share in the festivities and join our group of  ‘Celebrate 70’ ambassadors. We value your ideas, wisdom and perspective!

Seventy years ago a group of interested residents and organizations knew that it was important to create a place where wildlife and its habitat would be the top priority, and where people would have opportunities to connect with nature. Today that focus is more important than ever, and while the Nature Center has stayed true to its core founding mission, we have expanded our role in conservation and land stewardship. We continue to explore inter-relationships to better understand our place in nature and our responsibilities to protect it through programs and activities that include sustainable agriculture, history, art, cooking, music and recreation. We work hard to lead the way in environmental thought and action for our region, state and even all of New England, and we thank you for joining us on this exciting journey.
