Start the summer off by learning more about our streams. The Audubon Naturalist Society, which has sponsored a biological water quality monitoring program for 25 years, is now offering classes in stream science and invasive plant identification. The classes are open to anyone 10 years and older who has an interest in learning about local streams or who is considering joining our program. Summer is a great time to get to know life in our waters!
Introduction to Stream Science*
Healthy Stream Biology
Section C: Tuesday, June 5 (7-9:30 pm)
Woodend Sanctuary, Chevy Chase, MD
In the classroom, we will explore how “benthic macroinvertebrates” — organisms that live in the bottom of our streams – help us assess a stream’s health. We will learn how to identify these organisms to the taxonomic level of order through a PowerPoint presentation and by examining preserved specimens in a hands-on session with microscopes.
Section B: Saturday, June 9 (9:30 am – 12 pm)
Ten Mile Creek, Boyds, MD
In the field workshop, we will visit a healthy stream to practice monitoring techniques and to collect and identify the benthic macroinvertebrates we find.
Know Your Invasive Plants
Woodend Sanctuary (Teale Center), Chevy Chase, MD
Saturday, May 19 (9:30 am-noon)
Invasive plants that kill or bring down mature trees can seriously alter stream health and ecosystem function. Volunteer Master Naturalist Diyan Rahaman will help you identify non-native invasive plants at Woodend and in nearby Rock Creek Park.
