the study examined thousands of forest plots with detailed data and observation, considering 27 parameters, including the role of forest fire, emissions savings from bioenergy use, wood product substitution, insect infestations, forest thinning, energy and processes needed to produce biofuels, and many other. it looked at four basic scenarios: "business as usual" ; forest management primarily for fire prevention purposes; additional levels of harvest to prevent fire but also make such operations more economically fesible; and significant bioenergy production while contributing to fire reducation.
