Creating Shallow Water Wetlands

In the spring of 2007 a project was undertaken to build a shallow water wetland in a courtyard of Valley Forge High School, Parma Hts, Ohio. Looking back at my time spent working on this project, it is an amazing success. The school is using this wetland as a working lab for the biology, art and chemistry students. It really is true that if you build it they will come. There is never a day that we are not amazed by the activities of this man-made wetland. Check out the link to my website for this wetland and make sure you look at all the pages right of the home page. I was told many times that it was impossible to make this happen but as you will see in my website nothing is impossible if you really want it to happen. But of course, it is all up to you.

35 truck loads of hand dug clay was wheelbarrowed through the hallways and dumped in the front of the school. A total of 125 students, teachers , administrators and alumni worked to make this project a great success. It is planted with native pants and we will work to improve it as we go. The wetland has since been register with the National Wildlife Federation.

"Flash floods have increased in urban area over the last 20 years. This is in part by the loss of wetlands from Northeast Ohio and the urban sprawl that has occured leaving much of the land covered in concrete and putting the bulk of runoff in the sewers which quickly dump into streams and then major rivers.

This is a one of a kind project design of a wetland that will also be a nature center. The students will design a way to divert rain water from the school roof to the wetland, dig the wetland to specific standards for sustaining life, remove non-native species of plants and replace with native ones, stock wetland with wildlife, create learning posts and guide brochures, design a website, design and conduct tours for visitors, design hands-on experiments easily performed by students and grade appropriate according to state content standards.

At Valley Forge, we have created a living land lab to educate students about eleviating the flash floods around urban areas, wetland management, native vs. non-native organisms, classification of organisms, pollution, recycling, food webs, and populations."

Winter Solstice Spotted Salamander

Spotted Salamander
Seen in Ohio Snow


As reported on Ohio Vernal Pool Partnership by Tim Mason, a spotted salamander was photographed on Sunday December 20th, 2009 walking across the snow at The Dawes Arboretum.








Now, doesn't this tenaciousness cold-blooded creature represent the spirit of Ohio better than the bullfrog that simply won't be seen for another 5 months.






When choosing an Ohio State amphibian, let's adopt this critter to represent our spirit, style and ruggedness in the Great State of Ohio.

Lake Erie wetlands break down harmful chemical compounds

Thanks to Kathleen for bringing this to our attention:

COLUMBUS, OH – Beyond being a haven for wildlife and plant life, wetland areas provide the right mix of chemical compounds and physical characteristics to break down harmful pollutants, according to Ohio Sea Grant research from Dr. Yo Chin, Professor of Geology at Ohio State University.

Chin and his graduate student Ale Hakala have determined that over time, pentachloronitrobenzene (PCNB), an antifungal chemical now banned for use on most crops in the U.S., can be reduced to pentachloroaniline (PCA), a compound that should be more readily broken down by wetland bacteria.

Chin studied the process at Old Woman Creek National Estuarine Research Reserve in Huron, Ohio, using a technique he has perfected over more than a decade that slowly pulls water out of sediment in an oxygen-free environment. Keeping oxygen out is important because the main catalyst in the PCNB-to-PCA reaction is a form of iron scientists call iron 2 (or, Fe(II)). If even the smallest amount of oxygen gets in, the iron oxidizes to Fe(III), commonly known as rust, thereby ruining the experiment.

In the laboratory setting, when the water from the sediment had been chemically stabilized, the reaction turning PCNB to PCA was completed in two hours. But, surprisingly, the same reaction took one week when the team used water that hadn’t been stabilized—the way it would be found in the wetland. This discovery opened Chin’s eyes.

“Everything we’ve done, everything anyone has done with these pore waters, was based on manipulated compounds,” he says. “In nature, the compounds aren’t manipulated in that way, so the reaction takes a week instead of two hours. Doing it in the lab allows you to control things, but the take-home message here is that nature doesn’t want to be controlled.”
