Alabama, 2012 - forest inventory and analysis factsheet
These early surveys were not concerned with the forests, species, and tree sizes that were not considered commercially viable. Early surveys reported only on growing-stock trees on timberlands, i.e. commercially important tree species and tree sizes on forests that could sustain harvest operations. Currently, FIA reports on all of the forest lands regardless of site productivity or the potential to provide forest products. This science update will focus on long-term trends using the traditional measures of growing stock and timberland. A more detailed analysis focusing on all forest lands, tree species, and sizes will follow this science update.
