Stream Science at ANS
For 25 years, ANS has been teaching the natural history of aquatic ecology and training volunteer stream monitors who track the health of our region’s streams. Learn from the experts: study stream science in our introductory classes, and you just might be inspired to become a stream monitor yourself! Our advanced classes are perfect for those interested in deepening their knowledge about biological stream monitoring and are taught by our Maryland Biological Stream Survey-certified instructor Cathy Wiss.
Registration & Fee Information
Registration required: click here to register online. The classes are open to anyone 10 years and older. Except for Macro ID Review & Quiz, prices for all classes are $15 Members/$25 non-members (plus a $1 non-refundable registration fee per class); waivers are available for existing monitors and students earning SSL credit—email firstname.lastname@example.org for details.
Introduction to Stream Science Series* NONE AT THIS TIME
Healthy Stream Biology
Woodend Sanctuary, Chevy Chase, MD
In the classroom, we will explore how “benthic macroinvertebrates” – organisms that live in the bottom of 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 through a hands-on session with microscopes. REGISTER ONLINE.
Field Workshop NONE AT THIS TIME
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. REGISTER ONLINE.
How to Read Your Stream* NONE AT THIS TIME
Woodend Sanctuary, Chevy Chase, MD
Learn about the influence of land uses on streams, stream character and dynamics, bank erosion, bar formation, substrate composition, different velocity-depth regimes, and the importance of riffles and riparian vegetation. We will practice assessing stream habitat by using photographs of streams and the forms that monitors fill out in the field. This class is recommended for anyone who plans to participate in the ANS water quality monitoring program and is a good refresher on habitat assessment for experienced monitors. REGISTER ONLINE.
Advanced Series: Aquatic Insect Family ID** NONE AT THIS TIME
Woodend Sanctuary, Chevy Chase, MD (7-9:30 pm)
A: Beetles, Megaloptera & Water Bugs
B: Caddisflies & Aquatic Moths
C: Dragonflies, Damselflies & True Flies
E: Stoneflies & Review
Learn how to identify aquatic insects to the taxonomic level of family through this series of five classes. Identification to family level greatly enhances our understanding of stream ecology and the power of our monitoring data. These classes are great for fly fishermen, citizen science program or team leaders, aquatic resource biologists, and anyone interested in monitoring and understanding stream health.
Aquatic Insect ID Review & Quiz ** NONE AT THIS TIME
Woodend Sanctuary, Chevy Chase, MD (No fee)
Time to separate the mayflies from the stoneflies! Those who wish to be certified to identify macroinvertebrates in the field in ANS’ program must demonstrate their ability annually by taking a quiz using preserved specimens. Those who do not take the quiz may still be assigned to a monitoring team to assist with data collection and other field logistics, but only those who have taken and passed the quiz will identify macroinvertebrates for data recording.
Know Your Invasive Plants NONE AT THIS TIME
Woodend Sanctuary (Teale), Chevy Chase, MD
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. An ANS/Rock Creek
Conservancy Partnership. REGISTER ONLINE.
*Recommended for anyone who plans to participate in the ANS Water Quality Monitoring Program
