Pop-up nature center series at the Four Mile Run Farmers & Artisans Market

We are pleased to collaborate with Arlington Regional Master Naturalists to offer a monthly pop-up nature center activity during the Sunday farmers market at Four Mile Run. Stop by and learn about the fascinating nature that can be found at lower Four Mile Run, while enjoying the fresh produce, fine eats, and hand-crafted works of local vendors. This month, August 29, the pop-up nature center will highlight the dragonflies and other insects of Four Mile Run, so we hope to see you there!

Kayak clean-up dates announced for August and September

Come join our late summer and early fall kayak clean-up events, protecting local waterways and exploring nearby nature in Alexandria/Arlington. Volunteer registration opens for each event approximately 2-3 weeks prior.

City Nature Challenge April 30 - May 3

See Ospreys and more!
Explore nature in your neighborhood or park and contribute to scientific understanding of biodiversity during the City Nature Challenge! Using the free iNaturalist app, capture clear photos of wild plants, animals, fungi, and other living organisms, and share them with a worldwide network of hobbyists, naturalists, and scientists to learn about the nature around you. At the same time you'll be adding to a global data set that helps us understand the distribution, movement, and diversity of life on our planet.

During the City Nature Challenge, we are pleased to lead two public walks to support data collection: on Friday evening, April 30, find out what bats live in Four Mile Run Park as we look and listen for frog calls and, using an ultrasonic recorder, identify flying bats by their unique echolocation calls. On Saturday morning, May 1, join us for a bird walk along the different habitat areas of the park. See details and sign up for the Bat & Frog Walk, Bird Walk, or both!
