Presentation: Finding Nature's Secret Garden, 3/30/21
Maryland Master Naturalist Paula Wang
gave us a virtual preview of the short-lived woodland treasures along the Northwest Branch and other local trails. She included key identification features, medicinal uses, and folklore associated with these spring ephemeral visual treats. She shared just where to find whole arrays of flowers--and also warned of the inroads being made by non-native invasives such as Lesser Celandine. The trail guide she mentioned in her talk and the slides she used can be downloaded below. If you want to review the entire presentation, check out the YouTube (below, or click on Spring Beauties). Toward the end of the presentation, you'll hear a variety of frog calls, identified. Enjoy! And then get out on the trails very soon, before many of these flowers are gone.

Role of Montgomery Parks in Monitoring and Protecting the NWB
The program covered biological monitoring background and long-term monitoring results; stream restoration project updates, especially focused on the Glenallan Tributary to the NWB; other stormwater mitigation & water quality enhancement efforts; and volunteer services updates. Our presenters were Rachel Gauza, Biological Monitoring Program Coordinator; Erin McArdle, P.E., Environmental Engineer; Jackie Hoban, Senior Natural Resources Specialist; and Valeria Espinoza, Stream & Parks Cleanup Coordinator. Doug Stephens, Principal Natural Resources Specialist, kept an eye on the chat questions and provided answers. A YouTube video of the presentation is linked here.

The Forest in Winter: What to watch for
On Tuesday, Dec. 1, Maryland Master Naturalist and science educator Paula Wang treated us to a virtual look around the winter forest, and my oh my, what we've been missing! Winter has its own interesting natural phenomena--among the trees, on the forest floor, and birds you can actually see now that the leaves are gone. Paula captured it all in pictures. If you missed the program, or would like to review, you can find a video of the complete presentation, courtesy of NNWB member Ed Murtagh, here. To review a particular slide, pause the video. Enjoy your winter walks with new powers of observation!
Presentation: Microplastic Pollution, 2/4/20
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.

Presentation: Plastics Impact on the NW Branch, 6/12/19
Wednesday, June 12, 2019, 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.
