Two young stream cleaners with bags of trash and recyclables

Upper Northwest Branch cleanup

Saturday, May 4, 9:30 - 11:30 a.m.

Leader: Vanessa Kulick, vankulick@gmail.com

Park along Alderton Rd. near the NWB Trailhead.  Access Alderton from Bonifant Rd.

Wear long pants, long sleeves, and shoes that can get muddy.  Rubber boots would be even better, as some of the area is low and holds water.   Bring your water bottle.  Gloves and bags will be provided.  We will walk about 10 minutes to the NWB from the end of the NWB Trail.   If you weren't available for our April cleanups, here's another chance--and a chance to see a part of the NWB you may not be familiar with!  You might get a chance to see how the environmental mitigation under the ICC is doing.  Join us!

Recent event: Deer Management in Montgomery County

October 3, 2018: A crowd of more than 20 residents heard from Ryan Butler, Principal Natural Resources Specialist at Montgomery County Parks, about deer impacts on our parks and on people.  He outlined current and ongoing deer population management projects near the Northwest Branch Stream Valley and said that Northwest Branch Stream Valley Unit #4 and Sligo Creek Stream Valley Unit #5 will soon be added to Park Police-based sharpshooting operations.  He stressed that before a shot is fired, the sharpshooter must track where the bullet will land and ensure there is a backstop. Participants raised the question of birth control rather than culling. This is not deemed currently feasible for such a mobile and unconstrained  population.  Park police telephone numbers to keep handy:

 Emergencies - 301-949-3010. 

Non-emergencies, i.e., to report a wounded deer, 301-949-8010.
