Streamside management zones (SMZs) and road beautifying buffers (RBBs) in Georgia have had an unknown impact on the available wood supply in the state. We used Forest Inventory and Analysis data, Landsat Thematic Mapper imagery, Gap Analysis Program and other geographic information system data to estimate the potential impact of SMZs and RBBs in the current and future Georgia forest inventories. The analyzed scenarios are based on long-term simulations of wood supply in the State under various assumptions of regulatory constraints, expected harvesting, and intensities of management practices. The results are expressed in the form of affected areas and volumes. Obtained results suggest that introducing only some of the harvesting constraints would not drastically affect sustainable fiber supply in the State, even in the presence of increased future harvesting. The cumulative impact of obligatory SMZs, RBBs, and other anticipated factors, such as potential loss of forested land to urban expansion, could have a strong negative impact on the level of sustainable harvesting, reducing the future fiber supply in Georgia.
