Creating a Bog at Daniels Run ES

On October 5th, 2012

Our bog creation project at Daniels Run Elementary School was funded by a watershed grant from the National Fish and Wildlife Foundation. The site was a problem area adjacent to a playground with a compacted clay foundation. After a rain event, water collected here and stood for numerous days. Lands and Waters and Daniels Run decided this was an excellent opportunity to create a bog-type wetland using stormwater runoff, turning a problematic area into an ecosystem that students can study.

Our first step was to create a berm that would deflect the water from the foundation of the nearby trailer.

Building blocks: our hardworking team member Phillip uses precast concrete blocks and re-purposes them to create a wall.

Phillip them creates a gentle slop away from the wall with the existing clay that was in the area.

The students of Daniels Run, eager to lend a hand, skirted recess time to help us compact the clay slope.

Here we see the bog at work after a rain event! The berm is effectively draining water more quickly than before. Phase one is completed.

Next, we must evcavate out in a basin shaped pool, place in exploratory structures to encourage student engagement (while protecting protecting flora and fauna), amend excavated clay by mixing it with composted leaf mulch, and create a ponding area of no more than 4 inches. Finally, we will plant with native riparian herbaceous plants — our favorites are swamp milkweed, cardinal flower, turtlehead, joe pyeweed, and great blue lobelia. Whew, there is still much to do! But we’re off to a wonderful start.

Creating a Vernal Pool at Daniels Run ES: Breaking Ground (Part 1)

For a project funded by a generous National Fish and Wildlife grant, we begin breaking ground on a series of stormwater projects at Daniels Run Elementary in Fairfax, Virginia.

Breaking ground on a vernal pool construction project!

Something tells me this isn’t the first time we’ve lost Kris down a hole…

Kris pulled out a few volunteers that eagerly inhabited the hole that was used to check the soil profile and test percolation. I guess they are impatiently awaiting their new home! We relocated a few pickerel frogs (Lithobates palustris) to a nearby constructed wetland that was part of an earlier schoolyard greening project.

Relocating natives — we work to find new homes for the goldenrod and chestnut oaks that were at the site of our vernal pool creation project.

All in a days work! Digging out a vernal pool by hand (aka people-power) requires a lot of physical labor.
