Volunteer with the Calvert Stewards
The Calvert Stewards volunteer program provides an opportunity for public service in education, research, and stewardship which support the overall missions of the Calvert County Division of Natural Resources and the Calvert Nature Society. This benefits the participants, the parks and the community as Calvert Stewards use and develop their skills to form an environmentally aware community and become the environmental stewards of Calvert County. We also encourage youth and families to volunteer for projects to create a pipeline of engaged citizens that will continue their involvement in the parks into adulthood.

- Lower Marlboro Freedom Day, Saturday October 8, 2022. As the War of 1812 raged into the summer of 1814, British troops sailed up the Patuxent River in a bid to take Washington, D.C. They stopped to commandeer supplies at the port of Lower Marlboro in what is now Owings and offered freedom to local slaves in exchange for their service in the British war effort. Fourteen men and women won their freedom on an occasion that is now commemorated as Lower Marlboro Freedom Day. This year’s celebration will behave walking tours, speakers, entertainment, food and exhibits at the historic Lower Marlboro United Methodist Church and Lower Marlboro Hall in Owings and All Saints Episcopal Church in Sunderland. Maryland Department of Natural Resources will host a free fishing at the pier; under 16 years old do not require a fishing license; those older than 16 should apply for their license before the event: https://dnr.maryland.gov/Pages/service_fishing_license.aspx
