The following is a list of rare and endangered animals and plants in Connecticut from the Natural Diversity Database (NDDB), sorted by group and then genus and species. It is current through 2015, the most recent year that has been issued by CT DEEP. I am posting it because it is no longer available at the CT DEEP Landowner Incentive Program website. The list can be cut and pasted into a spreadsheet to sort as needed. I can also provide the list in Word format on request. The current official document, while not well sorted and not machine readable, is here: http://www.ct.gov/deep/lib/deep/wildlife/pdf_files/nongame/ets15.pdf
