Discover the underwater world of macroinvertebrates. See them up close and learn how they indicate stream health and what roles they play in stream ecology. NHSM volunteers will show participants how to catch and identify macroinvertebrates. Suitable for ages 6 and up. All equipment will be provided. Dress for the weather and prepare to get wet and muddy.
Macroinvertebrates are organisms that are large (macro) enough to be seen with the naked eye and lack a backbone (invertebrate). They inhabit all types of running waters, from fast-flowing mountain streams to slow-moving muddy rivers. Examples of aquatic macroinvertebrates include insects (in their adult, larval, or nymph forms), mollusks, crustaceans, and worms (Viklund, 2011).
Location – Gwynns Falls/Leakin Park, Baltimore (exact meeting location will be provided upon registration)
Free, but please RSVP for planning purposes. Donations are accepted and much appreciated.
ABOUT Gwynns Falls/Leakin Park is one of the largest woodland parks in an East coast city, constituting a contiguous area of 1000 acres (400 hectares), 84% of which is forest. Envisioned as a “stream valley park” to protect Baltimore’s watersheds from overdevelopment and to preserve their natural habitats, Gwynns Falls/Leakin Park today offers a rare opportunity for the public to explore a diverse natural environment characterized by stream valleys, ridge tops, and meadows; enjoy opportunities for active recreation; and experience historic structures from an earlier era.
Gwynns Falls/Leakin Park, designated as part of the Baltimore National Heritage Area, is managed and maintained by the Baltimore City Department of Recreation and Parks, assisted and supported by volunteers of the Friends of Gwynns Falls/Leakin Park (FoGFLP).
