Logging and mill residues are currently the largest sources of woody biomass for bioenergy in the US, but short-rotation woody crops (SRWCs) are expected to become a larger contributor to biomass production, primarily on lands marginal for food production. However, there are very few studies on the environmental effects of SRWCs, and most have been conducted at stand rather than at watershed scales.

This dataset reports the pre-treatment hydrology and pre- and post-treatment water quality data from a watershed-scale experiment that is evaluating the effects of growing short-rotation loblolly pine for bioenergy on water quality and quantity in the southeastern U.S. The experiment is taking place on the Savannah River Site, near New Ellenton, South Carolina, USA.  Beginning in 2010, water quality and hydrology were measured for two years in 3 watersheds (R, B, C).

Eucalyptus spp. is the world’s most widely planted hardwood species. It has been established and produced successfully in warmer regions of the U.S. for decades, and is positioned for commercialization as a biomass feedstock in the U.S. South. Plantation management options for Eucalyptus as a short-rotation woody crop include both single-stem and coppicing systems, with harvests every 3-7 years with average annual yields ranging from about 4 to 14 dry tons acre-1 year-1.
