Join a BioBlitz this month!

There are two opportunities this month to participate in BioBlitz events at Four Mile Run. A BioBlitz is a crowd-sourced effort to document wild nature of a place during a specified time period. People of all ages and levels of expertise are encouraged to participate. This month, the Home River BioBlitz and the Virginia Academy of Science are each leading BioBlitz events that cover Four Mile Run. The observations made during these events will help expand our knowledge of the urban ecology of the Run. Details are on our Events Calendar and at the event registration links below.

Four Mile Run BioBlitz: Sunday, September 20 (all-day)

Virginia BioBlitz 2020: Saturday, September 26 (all-day)

Both use the free iNaturalist app as the platform for sharing observations, and if you've never used it, you might want to try. You'll find it useful for helping identify that interesting flower, or bug, or bird, etc, that you find in your wanderings -- anywhere in the world!

Video: Tracing Hume Spring

As part of Water Discovery Week, we made a 9-minute video that follows the Hume Spring tributary stream from its source to its confluence with Four Mile Run. This small stream, which flows through Monticello Park, also flows for some of its course underground in stormwater pipes, collecting water off the streets as it goes. Check out the video on YouTube to learn a little about this interesting waterway in Alexandria.

 

You can use the City's GIS Sewer Viewer mapping tool to find out where your storm drains go. If you would like to mark storm drains in your Alexandria neighborhood, or to help monitor water quality in Four Mile Run and its tributaries, please email us at citizenscience@fourmilerun.org.

River Health Exploration: Wednesday afternoon pop-up exhibits

Meet us at Four Mile Run Park, along the trail near the end of Commonwealth Avenue, for a weekly pop-up nature center exhibit, through October 21. Each week will feature a different aspect of the nature and river health of Four Mile Run. Last week dragonflies, this week: water transport of stream sediments. Stop by between 4 and 6 p.m.


The 2020 River Health Exploration series is provided through grant support from Virginia American Water.
