The Foundation is dedicated to education, low-impact recreation, historic and environmental preservation and conservation of the scenic value, natural heritage and cultural history of the site.” The Caumsett Foundation has been recognized as a model “friends group.” We work closely with New York State Parks and the community toward a common mission: to support and enhance Caumsett State Historic Park Preserve as a unique and historic environment.

Our Projects
Grassland Restoration
Restoration of a 30 acre former pasture that contained woody vegetation, invasive vines and plants. The long term goal is to transform this site that for decades had been used for cattle grazing, into a native grassland, able to support the grassland dependent species.
Baltimore Checkerspot Butterfly Colony
Caumsett State Historic Park Preserve contains the only known breeding colony of the Baltimore Checkerspot Butterfly on all of Long Island. While this butterfly is found throughout New York State there have only been 4 records on Long Island over a period of 40 years prior to its discovery at Caumsett in 2009.
