Bark plays the roles of reducing water loss from stems, minimising risk of fungal or insect attack, protecting from fire damage; but once harvested can be considered as a feedstock for greener alternatives to fossil-based products. Often pelleted alongside other woody biomass for bioenergy purposes, bark typically has relatively high ash content and causes residue build-up in furnaces.
