Nature Forward stream monitoring volunteers will be finding, identifying and counting macroinvertebrates that live in Northwest Branch. You are invited to drop by to peek at these amazing critters under a microscope, try identifying them, and learn what they are telling us about the health of the stream. We’ll meet along Northwest Branch near Adelphi Mill Rec Center, 8402 Riggs Rd, Adelphi, MD 20783.
