- 요약In light of growing sustainability concerns and interest in the restoration of upland oak communities from both private and public sectors, this dissertation broadly examines the issue of oak (Quercus) sustainability through three lenses: prevailing harvest/management activity, accessibility of physical inventory, and potential management practices at a landscape scale. To that end, we adapt publicly available Forest Inventory and Analysis (FIA) data and perform a suite of empirical, spatial, and simulative analyses.To address prevailing/management concerns, we perform an empirical analysis that: a) explores the association between high-grading (an exploitative harvest practice) and mesophication; and b) assesses the role of on-site characteristics (including amenities) and market signal (price) driving the choice of harvest practice in oak forests of the southeastern US. Results show that high-grading has a significant and positive association with mesophication on harvested sites. Additionally, the random utility-based harvest choice model reveals that amenities and timber outputs have a complementary effect on the choice of high-grading. We further estimate the willingness-to-accept (WTA) value at $7.62 per thousand board feet, or $9.23 per acre, on average, across the region.To address accessibility concerns, we use a mix of regression and spatial analysis to estimate and map out the inventory reduction rate under some loosely categorized biophysical and social constraints on forest land in the eastern US. Additionally, we apply plot-specific reduction rates to estimate accessible timber inventory on timber basins across the eastern US; we extend this approach to estimate accessible carbon inventory together with accessible white oak (Quercus alba) inventory. Results indicate that site physiography, site productivity, ownership group, distance to road, slope, management experience, and amenity significantly contribute to the absence of management/harvest in the eastern forest land; the average inventory accessibility reduction rate is estimated at 0.88, ranging from 0.75 to 0.99. Additionally, more accessible spots (or lower inventory reduction rate) are significantly clustered in areas with relatively high harvest activity, such as the southern Atlantic and Gulf Coast Plains, southwest Arkansas, and the Northeast mixed forest in Maine. Conversely, less accessible spots (or higher inventory reduction rate) are significantly clustered in areas with little or no harvest activity, such as prairie parkland and shrubland in west Texas, the Ouachita Mountains, the Ozarks, and the Blue Ridge and Alleghany Mountains in the Central Appalachian broadleaf forest.To examine the potential of management practices for improved oak sustainability at a landscape level, we simulate a hypothetical management intervention in mixed oak forests in the southern Appalachian region of North Carolina. Specifically, this chapter applies the Forest Vegetation Simulator (FVS), a commonly used forest growth and yield model. We link existing plot-level FIA inventory data with two alternative management prescriptions - no management (consistent with current practices and market-driven high-grading) and under/mid/overstory removal of prolific oak competitors. Results suggest that the management intervention has the potential to enhance the timber value of stands by promoting the growth of "crop" tree species groups, such as oaks and hickories, generate upfront revenue from the removal of oak competitors - assuming markets exist - and reverse the mesophication of oak forests. This work suggests the need for policy interventions to support markets for small-diameter roundwood in Southern Appalachia to support both rural economic development and the future sustainability of these hardwood systems.
