A small band of volunteers turned out Saturday to clean up part of Cooper River Park in Camden County. This weekend's event called Cooper River Fest was just one of many similar events for the National Public Lands Day. The volunteers were part of the Cherry Hill Trail Crew – a volunteer program of the Cherry Hill Environmental Board. 

Jay Jones, Cherry Hill Trail Crew manager, who was on site this past Saturday cleaning up the Kresson Trail says that the greenery around rivers filters runoff water from the built-up and developed nearby towns.  "It's important that we keep the natural areas around the watershed because all of the trees and growth help filter that water."

The Cooper River Park in Camden County plays the same watershed role that Wissahickon or Pennypack parks play in Philadelphia, according to Jones. 

Another important task for Saturday's volunteers was to maintain the existing network of trails near Cooper River in Cherry Hill. Jones says it's when people use and interact with nature is when they learn to value it.
