What FOSC does

Friends of Sligo Creek (FOSC) offers events year round in support and appreciation of Sligo Creek and adjacent parkland. Litter clean-up and invasive plant clear-out events are among the most popular FOSC activities in the spring, summer and fall. FOSC also sponsors guided outdoor explorations of different sections and aspects of Sligo Creek flora and fauna. A wide variety of other programs throughout the year educate neighbors and users of the park about Sligo Creek’s strengths and challenges. FOSC also monitors the creek, advocating for civic policies that will support a healthier Sligo.

FOSC invites you to visit the creek, volunteer at an upcoming event, attend a program, advocate for the Creek, and join FOSC.

Thank you to everyone who came out to clear the creek and park of litter at the Sweep the Creek event.

See photos of sweepers and their finds, from the Sligo headwaters to the confluence with NW Branch, on the Sweep the Creek photos page. Send your pics to [email protected].

The weirdest find of this Sweep: scuba diving headgear and tank, found by the Section 1 Sweep team!

FOSC contributed to a formal appeal, by members of the Carole Highlands Neighborhood Assn, of the Prince George’s County Zoning Hearing Examiner’s recent approval of a 16-pump gas station adjacent to Sligo Creek Park at Riggs Rd. The appeal was drafted with pro-bono legal help from the Chesapeake Bay Foundation and participation by faculty and students in the Environment Law Clinic at the University of Maryland Carey School of Law. Read the appeal on the Letters and Testimony page.

Autumn forest of tall trees with leaves turning yellow, orange, and brown.FOSC Advocacy has been an active partner with the MoCo Forest Conservation Coalition to advocate for strong protection of MoCo’s remaining forests. In an April 28 Planning Commission hearing, the Coalition and many groups and individuals testified or submited written testimony arguing for stronger protections than the Commission’s proposed amendments to the existing Forest Conservation law would provide.

For more information about the issue and the bill, and to get sufficient information to write your own testimony, go to the Audubon Naturalist Society blog. You can use FOSC’s own written testimony as a guide for yours.

MoCo Councilmembers hold signs saying 'Electrify everything now' at the annoucement of the bill.
