Help keep the earth clean and green!

Members of the public are cordially invited to The Nature Conservancy’s (TNC) Annual Spring Watershed Cleanup at the First State National Historical Park. Volunteers will meet at the Pilot School parking lot in north Wilmington, Delaware at 10 a.m. on April 29, 2023. Staff and volunteers will be picking up trash in and around Rocky Run, a stream that feeds into the Brandywine.

“All too often, plastic waste and other trash clog our waterways and harm wildlife,” said TNC Delaware and Pennsylvania Chapter Executive Director Lori Brennan. “The annual cleanup is a great way to celebrate spring and help the natural environment.”  

“Cleanups are a fun way to connect to your local watershed and experience how individual actions can have a big collective impact for clean water,” said TNC Stream Stewards Project Manager Kim Hachadoorian. “Since 2016, volunteers have removed thousands of pounds of trash from our streams during these events.”

If attending, please meet in the parking lot and dress for the weather. Wear clothes and shoes that you don't mind getting dirty and wet. Plastic gloves and trash bags will be provided for the annual two-hour cleanup. This event is held rain or shine.

The annual cleanup is part of TNC’s Stream Stewards program and a key part of our goal to connect more people with nature and inspire action to protect clean water. The community science program engages people of all ages and backgrounds in watershed stewardship. Originally launched in 2016, volunteers collect and report water-quality data from the streams that flow through First State National Historical Park to Brandywine Creek.  

To learn more about Stream Stewards, check out our four-part video series consisting of a program overview and a look at the three main components of Stream Stewards: youth engagement, community science, and public outreach and education. If you are inspired by what you see, more volunteers are always welcome!  

Can’t make the cleanup? Host your own independent event, take photos and tag us on social media. There are many other small things you can do to protect the planet. Limit your car travel, calculate your carbon footprint, use cloth bags when you shop, reduce household waste, avoid single-use food and drink containers and learn more about environmental justice work in our backyard.
