“…Increased residue usage is most easily accomplished by whole-tree harvest, with natural understory vegetation harvested mechanically [14][15][16]. Periodic natural understory vegetation would be more variable than a dedicated crop, causing potential conversion issues.…”

There is increasing interest in energy from woody biomass as fossil fuel replacement, yet environmental and economic limitations have reduced feedstock available for bioenergy. Supply could likely be substantially increased with intensive forest management for productivity and utilization as well as forest-based dedicated energy crops. This paper discusses the role of industrial forests in sustainable bioenergy feedstock production and the lessons learned in an operational scale project. Catchlight Energy, LLC, a Chevron|Weyerhaeuser joint venture, evaluated intercropping switchgrass (Panicum virgatum) in loblolly pine plantations for liquid transportation fuel, with the goal of full-scale production. Within Weyerhaeuser, sustainability and operational research were conducted simultaneously. While the environmental research is non-proprietary and being published as it is completed, operational trials were internal. To understand lessons learned, staff responsible for management, planning, logistics, and field operations were interviewed, and perceived and actual barriers to production described. Ongoing environmental research is showing that carefully planned field operations can be conducted sustainably, but energy crop production fell below levels needed for economic feasibility.

Post-wildfire regenerated Mediterranean pine stands have a high risk of wildfire recurrence. Preventive clearings are frequently applied in a mix of systematic and selective ways, being a potential biomass source using technologies such as the collector-bundler BioBaler WB55. Our research aimed to compare the BioBaler with a chain mulcher performing systematic mulching of 50% vs. 67% of stand surface over 11.4 ha dominated by Pinus pinaster Ait. regenerated after a severe wildfire. Time studies included the machinery GPS follow-up and the weighing of each produced bale. Environmental aspects were also assessed. A regression curve related BioBaler weight productivity (odt·Workh−1) to pine biovolume (cover (%) average tree height, m). Surface productivity (stand ha·Workh−1) was greater for both technologies when a lower percentage of the total surface was cleared, but less than theoretically predicted. The BioBaler’s economic balance, including the cost of further selective clearing and the income from biomass selling, was costlier than that of the mulcher—in the most representative strata, 475 EUR·ha−1 vs. 350 EUR·ha−1. Under the studied conditions, BioBaler was not economically competitive with the conventional treatment, its main constraint being low collection efficiency (31% of the standing biomass in the cleared surface, 5.33 out of 17.1 fresh tonnes·ha−1).
