Restoring Disturbed Landscapes

While urban sprawl contributes to deforestation, many areas in the US now have more forests than they did a century – or a few decades – ago. These afforested areas are super-imposed on landscapes with a legacy of human activities, including agriculture and mining. Both abandoned agricultural lands and reclaimed mine sites feature disrupted drainage networks and altered soil profiles and properties, relative to their pre-disturbance conditions. These changes alter the partitioning of water between the surface and subsurface and may affect success and ecohydrology of reforestation efforts.

Ongoing Research

In partnership with Cuyahoga Valley National Park, the FoSTER (Forest Soil and Trees Ecosystem Restoration) project aims to (1) understand why abandoned and reclaimed surface mine and quarry sites have failed to reforest and (2) study the effectiveness of new restoration efforts including deep ripping and volunteer-led tree planting. My Kent State collaborators on the project are Dr. Chris Blackwood and Dr. Christie Bahlai in Biological Sciences. If afforestation is successful, we intend to use these sites as long term ecohydrologic research laboratories, where we can watch the co-evolution of soils, hydrology, and above and below-ground ecosystems. You can hear me talk about the project in a 6 minute interview recorded in spring 2018. Catherine Ruhm completed a MS thesis characterizing the sites’ soils prior to deep-ripping, and Mike Back recently completed an undergraduate Honors thesis on bulk density profiles within and between of ripped areas.

Recent Projects

I’ve also worked on legacy effects of intensive agriculture on modern channel head positions, stream sediments impacted by acid mine drainage, and island growth upstream of dams. If humans historically altered the landscape, there is science to be done to understand how it functions now and how we might alter function through restoration activities.
