Areas to be studied include frogs, salamanders, vernal pools, several bird related projects and several pollinator related projects including monarch butterflies.

Special Events

Special Event Volunteers are needed at the Maple Sugaring Festival, Tex Mex 5k Race, Walk the Wissahickon, Green Ribbon Gala, and the Green Ribbon Trail Race. At these events, volunteers can help with a wide spectrum of jobs both before and at the event, such as marshalling a race, leading a hike, or serving food at various events. If you would like to be added to the special event email list, please note that when you sign up. 

Evans-Mumbower Mill

The Evans-Mumbower Mill hosts a dedicated group of volunteers who share their passion for history.  Mill Open House volunteers open and operate the mill seven times a year for the public to tour.

The mill was built in 1744, and maintaining the almost 300 year old structure is no easy feat, which is why mill maintenance volunteers are so important. These volunteers complete maintenance jobs, improvement projects and carpentry. The mill is currently in need of additional maintenance volunteers. 


WVWA’s Education program needs caring volunteers to assist with the elementary and secondary education programs. In the spring and fall, elementary school students visit the Evans-Mumbower Mill to learn about simple machines and the history of mills and the local area. In the spring, high school students join us at the Wissahickon Creek to learn about the science of water quality, the challenges facing the Wissahickon Creek and macro-invertebrates. Volunteers are needed to help lead the lessons and assist the students and volunteer leaders. We offer training for these programs as well as guidance in obtaining clearances for working with children. Previous teaching is a plus but not a must.

Creek Watch Program

Creek Watch is a team of trained citizen scientists that regularly monitor the Wissahickon Watershed and report their findings back to the WVWA. Each Creek Watcher is assigned a section of the Wissahickon Creek or tributary by the WVWA to be visited once a month. At this time several sections are in need of volunteers. If you are interested in becoming a Creek Watcher, please note that in the sign up form.

Conservation Crew

Conservation Crew members are trained volunteers that have been assigned sections of the Green Ribbon Trail and the Preserves to monitor and maintain each month. They keep the trail and preserves free of trash, remove invasive plant species, assist with emergency trail work, help WVWA staff with stewardship projects and are responsible for reporting issues on the trail such as downed trees, dumping, etc.

Serve the Preserve

Every spring and fall WVWA holds the bi-annual Serve the Preserve. This service project is great for volunteers of all skill levels and ages. Serve the Preserve is held on one of WVWA Preserves or the Green Ribbon Trail. The projects include removing invasive plant species, replanting the area with native trees, shrubs and grasses or a clean up. This service project is a wonderful way to share your values with family members, friends or service groups.

Creek Clean Up

At the annual Creek Clean Up, volunteers are pre-assigned to sections of the creek and trail to clean. Canoes are also needed to help clean the deeper parts of the creek. The Creek Clean Up is a great volunteer opportunity for individuals, families and groups of all skill levels and ages to participate in.
