Join the Crayfish Corps! Help Valley Forge National Historical Park preserve our native crayfish, and contribute to the overall health and biodiversity of our streams.
Volunteers will assist the staff from Natural Resource Management (NRM) in the capture and return of native crayfish species, and removal of invasive, non-native crayfish species from select waterways in the park (e.g. Valley Creek). Removal will occur using dip nets, and possibly various trapping devices. Target species for removal is the rusty crayfish. The rusty crayfish is an aggressive non-native invasive species that threatens to out-compete and extirpate the two native crayfish species found in Valley Forge NHP.
Experienced volunteers may be asked to assist NRM staff on volunteer days to serve as crew leaders for other volunteer groups and to participate in activities related to education of the public regarding the need for control of invasive species in units of the National Park System.
Volunteers are not required to use their vehicle, but may assist in shuttling other volunteers if they agree to do so. Volunteers may be required to ride in a government vehicle to get to the work site. Seatbelt use is required.
If there is thunder or lightning, or if the water level is too high, the event will be cancelled.
Minimum number of participants is three, otherwise the session may be cancelled. Maximum number of participants for each session is 15, so sign up early!
Equipment (e.g. nets, traps, datasheets) will be provided by NRM staff. We will provide hip boots (some sizes may be limited) and nets, but bring your own if you have them. Felt waders are not allowed. You may also prefer to wear shorts and old sneakers or water shoes, instead of waders. Open-toed shoes and bare feet not allowed. Shoes must be close-toed. No exceptions. Water, sunscreen, a walking stick, and a hat are recommended. You may wish to bring a snack or lunch and insect repellent.
