Upcoming Events


2020 Meetings

Closure of the White Oak Library canceled our April, May, and June meetings.  Closure of library public rooms will continue through the end of the year because they are needed for storage as libraries rearrange themselves to keep users properly distant from each other.  We are considering Zoom meetings.  Meanwhile, we are participating in a joint Zoom meeting with Friends of Sligo Creek on June 23.  I will send the Zoom link to our listserv and database prior to the meeting date.  Program details:

  • June 23, 7:30 - 9:15: Speakers: Ryan Colliton, the new program manager for the Vegetation Ecology and Management Program at Montgomery Parks, and  Weed Warrior Coordinator Corinne Stephens.  They will discuss proposed updates to the Weed Warrior program and to the 2009 vegetation management plan for parks. 

The update will use new field data on the introduction and spread of invasives and survival of native plants.  A lot has happened since 2009!  (You can download the  2009 Vegetation Management Plan here.) 


Cribbing here from the FOSC newsletter, with thanks!---"The 2009 plan was  followed in 2013 by the broader "Natural Resources Management Plan for  Natural Areas in M-NCPPC Parkland in Montgomery County," which you can  read or download here: 2013 Natural Resources Management Plan.  It describes all the major habitats in the county and lists links to  all the management  plans (for deer and streams, for example). 

For more information on this event, email naturalhistory@fosc.org.  "


For the latest from Montgomery Park on what's opening up a little, see the COVID-19 virus update page at the button below.  The long and short of it is that activities such as group cleanups are still verboten, while tennis, boating and some other activities are now allowed.  

Just remember to take a bag and gloves along with you when you go for a walk in the park, and you can be a much-appreciated one-person clean-up crew!  Put the trash/recycling in the new cans that have sprouted up at trailheads, or take it home with you.  And remember to keep that safe distance between you and the others out on the trails.  This virus is revealing itself to be a real bear, even for the young. You really don't want to get it or give it to anyone else!

Recent Event: Microplastic Pollution

At our Feb. 4 meeting, Dr. Kathleen Michels described the toxic effects of microplastic pollution on aquatic life and seabirds. Dr. Michels stressed that plastic pollution includes the broken bits and dissolved toxins from artificial turf.  She displayed samples of the rug of plastic grass and the pulverized used tire crumbs that most often serve as infill for cushioning and to hold the blades up. Soccer fields contain roughly 675,000 square yards, or 40,000 pounds, of carpet with 400,000 pounds of infill. By the time the turf is too worn to use, a lot of the "grass" blades and much of the infill has already left the field and entered our waterways. But disposal of the rest is a serious problem, since it is not currently recyclable in the U.S.  Other microplastics are the result of the breakdown of larger plastic objects such as our ubiquitous plastic bags.

Unfortunately, none of the bills that would have reduced plastic pollution managed to pass the shortened session of the Maryland Legislature, even the balloon release ban, which had seemed very promising. However, a similar balloon release ban is still awaiting action in the Montgomery County Council.  Please let your state and county legislators know you support reducing killer plastic pollution, and we'll try again next year.

The absurdity of wasting scarce education money on these fields has been captured by the comic strip Big Nate.  In case you missed it, here's the URL. https://www.gocomics.com/bignate/2020/05/08.

Recent Event: Wheaton Regional Park Master Plan in the works

Chuck Kines, Montgomery County Parks Planner/Coordinator, updated us on the thinking behind the update of the Wheaton Park Master Plan. Although a regional park, Wheaton must also function as a local park, as it lies in a densely populated area.  His slide presentation, downloadable below, included maps and demographics.  The Parks Department is in the early stages of planning and welcomes input from park users.

Recent Event: 10/1/19 Program: Mechanized Bikes/Scooters


 Our  October 1 program featured Mr.  Charles Kines,  AICP, CPRP, Park  Planning Coordinator, who explained the Montgomery County pilot program  allowing mechanized bikes and scooters on paved park trails.  If you  missed the program, you can find information about it on the MoCo Parks  website at: Montgomery County's pilot program to allow mechanized bikes and scooters on paved park trails.  You can also find the slides from Mr. Kines' presentation  linked below.

Recent event: August 6 general meeting

The NNWB August meeting included reports on the beltway-I-270 expansion plan and a proposal to build a new middle school in the NWB floodplain in Hyattsville, both  using Public-Private Partnerships (P3). We also discussed the Montgomery Parks pilot project to allow certain mechanized bikes and scooters on paved park trails and NNWB plans and speakers for the fall.


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. 

Recent Event: Stream Clean-Up at W. Hyattsville Metro

July 1, 2018:  An enthusiastic team of five volunteers led by board member Maurie Kathan removed 9 bags of trash and 8 of recyclables from the stream and banks of the NW Branch behind the Metro station.  Many thanks to those who braved the very warm morning to improve the health and beauty of the Northwest Branch! 

Recent Event: Raingarden Plants that Attract Pollinators and Birds

Chris Lewis, Professional Horticulturist and manager of the garden shop at Behnkes, showed pictures and discussed the attributes of plants that do well in soggy sites.

Recent Event: Earth Day Stream Cleanups

NNWB sponsored three cleanup sites: Burnt Mills, Broad Acres Local Park, and the stretch of the NW Branch behind the W. Hyattsville Metro station.
