Abstract: The Tennessee Valley Authority (TVA) is conducting a small-scale pilot project on TVA owned land in Rhea County, Tennessee. The purpose of the project is to generate certified and fungible carbon offsets from planting indigenous trees and warm-season grasses on hay land; but more importantly, to develop internal knowledge and expertise that could be applied to similar, larger-scale projects in the future. The project site consists of five tracts totaling 41 acres. The site has been mainly used for farming. The current vegetation cover is primarily tall fescue. A mix of hardwood tress will be planted on two tracts of land (15 acres total). Switchgrass will be planted on one tract (12 acres) and other native warm-season grasses will be planted on the remaining two tracts (14 acres total). The 12-acre tract where the switchgrass will be planted will be divided into three 4-acre tracts to evaluate different row spacing. The trees will be hand-planted in early 2011 and the grasses will be planted in the spring of 2011. Soil and aboveground carbon measurements will be made prior to and after planting. Periodic carbon and biomass measurements will be made over a 10 to 20-year period. Environmental stewardship is an integral component of this project. Trees, grasses, and legumes that support biodiversity and wildlife habitat will be planted. Also, different planting, harvesting, and management practices for warm-season grasses will be used to evaluate the impact on soil carbon uptake and storage and biomass production.
