recent event: Impact of Plastics on the Northwest Branch


Wednesday, June 12, 7:30 - 8:45 p.m.: Impact of Plastics on the Northwest Branch

FEATURED SPEAKER Tiffany Boone-Hines, a Montgomery Blair High School student, spoke about her participation in One Montgomery Green's Clean Headwaters Program and what she has learned about the impact of plastics waste in marine environments through her hands-on study of the Northwest Branch and its tributaries.

Overall, plastic micro- and macro-pollution in waterways is a huge problem, and the Northwest Branch has its share of plastic waste.  The team, using a sieve to isolate particles which they then viewed under a microscope, found tiny bits of plastic foam and synthetic fibers.  Rather than rely on recycling plastics, we must reduce our use in the first place.   It appears that our removal of all those plastic bottles and cups from the NWB has been beneficial, however, as the amount of particles in the water was not overwhelming.  The slides from Tiffany's presentation can be viewed below.

One Montgomery Green is a local nonprofit fostering partnerships to support environmental sustainability and promote the development of a green economy.

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.
