Kellogg Estate, Osborndale State Park

Osborndale State Park is 350 acres located in Derby, CT, and was willed to the state by Francis Osborne-Kellogg in 1956. The park was comprised of land purchased and used for agricultural practices, but best known for the herd of Holstein cattle and its breeding lineage.  The history of this location and other educational offerings are shared at the Homestead Museum and Environmental Center, located off of Hawthorne Ave.  The Chronolog station is found in the meadow next to the center's parking lot.  It will be used to record the change in diversity of the meadow via a small restoration experiment to increase diversity of native flowers in the field.  This project began fall 2025, Meadow Diversity Project ,to see if small patches of native plantings can help increase diversity for improved pollinator activities, especially Monarch Butterflies.
