Utilizing a collaborative approach, built on community buy-in, a multilayered working group is attempting to build a large-scale multi-use human powered trail system on National Forest System land to diversify its economy through tourism, while enhancing the quality of life of the local communities. The collaborative approach led to the project being selected as the first recreation infrastructure project in the nation to utilize the Pay for Success (PFS) financing model for funding. Pay for Success is an innovative financing tool where investors provide upfront capital for a project with repayment tied to the successful achievement of those outcomes. Pay for Success offers several benefits for developing recreation infrastructure as it provides access to impact capital, reduces...

Ballard, Jr. Soil CO2 efflux (soil respiration) is the largest flux of carbon from terrestrial forest ecosystems. Understanding this flux in relation to forest thinning and prescribed burning is necessary for determining the effects of forest management on forest carbon dynamics. Since rising levels of atmospheric carbon dioxide are of global concern, my dissertation focused on providing insight into various aspects of soil respiration as it relates to forest management. Specifically, my research focused on (1) the effects of topographic position, canopy cover, and small-scale treatment on soil respiration (Rs) and soil microclimate; (2) modeling Rs with soil microclimate data and climate data; (3) the effects of large-scale forest thinning and prescribed fire on Rs and soil microclimat...

Attempts to understand the relationship between silvicultural practices and soil respiration are complicated by physical and biological heterogeneity at the landscape scale. We examined the effects of burning on soil temperature, soil moisture, and respiration while controlling for slope position and thinning intensity. Treatments included unburned control, low intensity fire, high intensity fire, lime fertilization, and leaf litter removal. These treatments (each 2×2 m) were replicated in 20 experimental blocks at different slope positions (upper vs. lower) and thinning treatments (closed canopy vs. 50-percent removal) in a mixed-oak forest in southeastern Ohio. Monthly field measurements were conducted from April to November in 2004. Treatment and slope position were significant factors principally during the growing season. Upslope and thinned plots experienced midsummer soil-water red...
