Across the nation and across Virginia, September is volunteerism month.

All 36 Virginia State Parks will offer volunteer opportunities throughout September.

Stewardship Virginia is a semiannual statewide initiative with projects that enhance and conserve Virginia’s natural and cultural resources. Volunteers receive a certificate of appreciation from Gov. Terry McAulliffe. Fall Stewardship Virginia runs Sept. 1 through Oct. 31 each year.

The weekend of Sept. 11-13 will commemorate the attacks of Sept. 11, 2001, with the National Day of Service and Remembrance.

Day to Serve, www.daytoserve.org, is a regional collaboration of the governors of Virginia, West Virginia and Maryland and the mayor of the District of Columbia with the goal of coming together to help people in need and improve communities between Sept. 11-28.

National Public Lands Day, coordinated through the National Environmental Education Foundation, www.publiclandsday.org, Sept. 26, is the nation’s largest single-day volunteer event in support of public lands. This year’s theme is “Helping Hands for America’s Lands.”
