The Ridges鈥� Kirkbride complex was sculpted from bricks formed from the grounds, creating lakes that contributed to a healing landscape for the mental health facility鈥檚 patients. For generations of OHIO students and the community, it was a place for recreation.

While those lakes no longer exist鈥攙ictims of frequent flooding and the subsequent re-routing of the Hocking River鈥攖he land at The Ridges continues to provide town and gown opportunities for recreation as well as learning and research.

Roughly 580 of The Ridges鈥� more than 700 acres have and will remain undeveloped. Under the Ridges Framework Plan, 163 acres have been designated conservation land, reserved for academic and recreational activities.

The approximately 205 acres of land northwest of The Ridges Green serves as The Ridges Land Lab鈥攊ts wildlife, more than 500 plant species and historic usage making it one of OHIO鈥檚 most unique classrooms and research spaces.

鈥淭he whole Ridges complex is an incredibly rich resource,鈥� says Dr. Brian McCarthy, MS 鈥�84, professor of forest ecology and senior associate dean of faculty research and graduate studies for the College of Arts and Sciences. 鈥淚t鈥檚 juxtaposed to 91探花, and the value of that is almost incalculable in terms of student, faculty and staff usage of the property, whether it be for recreational, personal or professional reasons.鈥�

McCarthy is one of three faculty members who serves on The Ridges Land Lab Committee, managing research conducted on the property鈥攐nce home to the farmland and orchards that made the mental health facility largely self-sufficient and provided purposeful work as part of the patients鈥� treatment.

鈥淭hat area has such a long history of human use,鈥� adds McCarthy. 鈥淭hese forests and fields are really an artifact of a hundred years ago. It gives us some insight into what was going on biologically back in that era that鈥檚 hard to come by otherwise.鈥�

Dr. Jared DeForest, associate professor of environmental and plant biology, has been fascinated by the Land Lab since joining the OHIO faculty in 2006. He鈥檚 uncovered mysteries鈥攍ike why Radar Hill is grassland instead of forest, working with a geology professor to determine that millions of years ago the hill was part of a freshwater lake鈥攁nd uses the Land Lab as a natural extension of his classroom.

鈥淚t鈥檚 just a gem,鈥� he says. 鈥淚t has so much diversity and hits on so many key concepts in plant and forest ecology.鈥�

The soil pits DeForest has dug at the Land Lab allow students to read the soil and determine the history of the area over millions of years. Students in his dendrology class are able to find nearly 40 species of trees on just one of the Land Lab鈥檚 trails. And the photographs he has taken there over the past 14 years illustrate changes in the forest.

鈥淪howing students these pictures creates an awareness of how dynamic a forest is, but it changes on timescales that make it difficult as humans to understand,鈥� DeForest says.

Over the past five years, doctoral candidate Kelsey Bryant has been doing field studies at the Land Lab.

鈥淵ou have literally four or five different ecosystems within walking distance at The Ridges Land Lab,鈥� Bryant notes. 鈥淲ithin like half a mile, you have people doing biofuel research, American Chestnut research, insect research, wildlife research, forest research. I鈥檝e made friends and work connections because of the Land Lab.鈥�

For her dissertation, Bryant studied how different trees respond to changes in water availability and annual weather, looking at six species of trees at the Land Lab.

Using sensors powered by solar panels, Bryant was able to determine how water moves in the trees, each species with its own internal water movement structure. Using ropes, so as not to harm her subjects, Bryant would climb the trees to harvest leaves, taking measurements that indicate the amount of water stress the trees were experiencing, which affects the amount of carbon dioxide they sequester.

鈥淚t鈥檚 really interesting how trees鈥攖hat have the same access to water, the same environments but different vessels through which they move water鈥攂ehave completely differently,鈥� Bryant says. 鈥淒oes that mean that in 50 years one of those species may not be as successful? That鈥檚 possible, and that鈥檚 really the broader significance.鈥�
