AbstractWoody biomass feedstock is suitable for direct combustion, gasification, pyrolysis, ethanol or methanol production yielding heat, charcoal, pyrolysis oil, green electricity and bio-propellants. However, there are several issues concerning the environmental, social and economic sustainability of woody biomass production connected to land use, protection of wildlife habitats, conservation and remediation of landscapes. Establishing energy plantations on arable lands or on grasslands is generally considered as working against nature conservation, while setting them up in polluted areas or wastelands could be advantageous for wildlife, because of 1. more permanent cover that provides shelter and biomass for feeding, which is especially important in winter periods; 2. higher architectural complexity of vegetation providing more place for nesting and feeding for wildlife; 3. exploiting the advantages of root filtration, phytoremediation, or using less chemicals; 4. forbs in the undergrowth and young shoots able to provide better quality food for wildlife than the intensive monocultures. The solution is a complex management system, including land use, phytoremediation, waste and wastewater management and ecosystem-based planning incorporated in one dynamic structure.
