Productivity and cost-effectiveness of short-rotation hardwoods on various land types in the southeastern USA.

Despite the growing need to produce energy crops, information on comprehensive feasibility of growing short-rotation woody crops (SRWCs) on non-contentious and less-utilized lands and lands transitioning from previous uses in the southeastern USA is limited. An assessment model (SRWC-PEAM) was developed and tested for assessing the feasibility of SRWCs on lands targeted for ecosystem-service enhancements based on land conditions, species, and stand and economic variables in the southeastern USA. Productivity and economic returns of sweetgum (), sycamore (), and poplar () stand differed due to land types, species' adaptability and biomass potential, and optimal land-type-based management schemes.

Coupling aquaculture with forest plantations for food, energy, and water resiliency.

Freshwater aquaculture and forest bioenergy markets are expanding globally in areas concurrently experiencing human population growth, urbanization and water shortages. Coupling these agroecosystems can improve food, energy, and water resiliency by enhancing ecosystem services through fertilization, water-reuse, carbon storage, and bioenergy via biomass production. This study evaluated how a model aquaculture-managed forest plantation could (1) provision fish and woody biomass; (2) regulate carbon, groundwater infiltration, and groundwater quality; and (3) support nutrient cycling over a two-year period.

Do biomass harvesting guidelines influence herpetofauna following harvests of logging residues for renewable energy?

Forests are a major supplier of renewable energy; however, gleaning logging residues for use as woody biomass feedstock could negatively alter habitat for species dependent on downed wood. Biomass Harvesting Guidelines (BHGs) recommend retaining a portion of woody biomass on the forest floor following harvest. Despite BHGs being developed to help ensure ecological sustainability, their contribution to biodiversity has not been evaluated experimentally at operational scales.

SRWC bioenergy productivity and economic feasibility on marginal lands.

Evolving bioenergy markets necessitate consideration of marginal lands for woody biomass production worldwide particularly the southeastern U.S., a prominent wood pellet exporter to Europe.
