<div>Prescribed fire is one of the most useful tools available to forest managers attempting to maintain oak-hickory forests in the Central Hardwood Region. Prescribed fire can be useful in promoting regeneration of desirable species groups like oak (Quercus spp.) and hickory (Carya spp.) by preparing the seedbed, managing competition, and creating canopy gaps. The use of prescribed fire has been limited by concerns regarding the effect of the practice on standing timber. A perception of strong negative effects to tree-quality and tree-value from fire originated largely from sometimes deleterious effects of wildfire on timber. Less research exists demonstrating the potential effects of controlled, prescribed burning on timber quality and value. Furthermore, most research that exists focuses on individual tree characteristics, and is often focused on a relatively small geographic areas.</div><div><br></div><div>I conducted a regional study on the effects of prescribed fire on timber quality across a gradient of the Central Hardwood Region, ranging from the Missouri Ozarks to the Appalachian foothills. I studied 139 stands in selected prescribed fire units and control sites in Mark Twain National Forest (MO), Hoosier National Forest (IN), Wayne National Forest (OH) and Daniel Boone National Forest (KY). Selected stands were dominated by hardwoods species and had variable prescribed fire histories, ranging from 0 to 6 prescribed fires. </div><div><br></div><div>Measurements were taken concurrently across this plot network for two studies. First, we assessed the estimated effect of prescribed fire on stumpage value, and secondly, we assessed wounding patterns and effects of prescribed fire on tree-quality. Loss in estimated stumpage value from prescribed fire averaged approximately 4.2% across all measured stands. Estimated loss in stumpage value varied significantly by the number of prescribed fires in the last 30 years, with increasing numbers of prescribed fires leading to higher estimated losses in stumpage value. Further, stands in Mark Twain National Forest exhibited higher estimated loss in stumpage value, exceeding 10% on average. Stands in Hoosier, Wayne, and Daniel Boone National Forest only rarely exceed 5% losses in estimated stumpage value, and averaged less than 3%. </div><div><br></div><div>Approximately 25% of trees had at least one wound associated with prescribed fire across all study sites, while approximately 5% of trees experienced a reduction in tree quality (as measured by United States Forest Service tree grade) from prescribed fire. Both the rate of wounding and rate of tree grade reduction increased with increasing numbers of prescribed fires. Stands in the western portion of the Central Hardwood Region (Hoosier and Mark Twain National Forest) exhibiting higher rates of wounding from fire compared to eastern sites (Wayne and Daniel Boone National Forest.)</div><div><br></div><div>Effects of wounding varied significantly by type of wound. Catfaces accounted for far more volume loss and reduction in tree grade than any other wound type. Alternatively, some wound types, like seams and bark slough, caused minimal tree-quality and tree-volume effects. Effects also varied by species, with higher wounding effects on sugar maple and red oak, and relatively low effects on white oak and yellow-poplar. </div><div><br></div>

<a>Global trends and factors, such as the increased level of globalization, climate change, resource scarcity, and awareness of social and environmental responsibilities, as well as fiercer competition and lower profit margins in all industries, force organizations to act to retain, regain, or sustain their competitive advantages for long-term survival. These trends and factors are historically known to bring about innovations that drive the evolution of industries. Sustainability is considered to be such an innovation to achieve fiscally sound, environmentally conscious, and socially progressive organizations and supply chains. Sustainable Development and Sustainability notions are among trending topics of 21st century. Elevated sustainability concerns of various stakeholders have been forcing members of all industries to evolve into their more environmentally and socially responsible versions. This study was initiated through a comprehensive literature review phase that reviewed 477 articles published in five major databases from 1990 to 2018. The purpose of this review was to assess the current state-of-the art on the subject of lean-driven sustainability. Based on descriptive and contextual analysis, synergies, divergences, and the extent of two-way permeability of lean and sustainability concepts from the perspective of intra- and inter-organizational operations were identified along with future research opportunities. Fundamental strengths and weaknesses of both concepts, existing strong synergies and untapped potential, along with their key contributors, the potential-use cases of lean tools to derive sustainable solutions are highlighted in this review. Next, based on the findings of systematic literature review, an innovative, holistic, versatile and scalable tool was developed to assess and benchmark sustainability performance of organizations and supply chains. The proposed framework was established upon trivet structure of Triple Bottom Line philosophy and fueled by Lean, Six-Sigma and Life Cycle Assessment (LCA) methodologies for accurate and effective measurement of sustainability performance. Completeness of the framework was ensured through development of first-generation Key Performance Indicator (KPI) pool with 33 indicators, a unique work environment assessment mechanism for safety and environmental protection issues in terms of 11 risk categories and by construction of an ownership structure for ease of framework deployment. Proposed framework is expected to help with true sustainability performance improvement and benchmarking objectives at a range of business levels from facility to sectoral operations. Upon completion of the development phase, the Sustainability Benchmarking Tool (SBT) Framework was validated at the facility level within the context of value-added wood products manufacturing. Strengths and weaknesses of the system were identified within the scope of Bronze Frontier maturity level of the framework and tackled through a six-step analytical and quantitative reasoning methodology. The secondary objective of the validation phase was to document how value-added wood products industries can take advantage of natural properties of wood to become frontiers of sustainability innovation. In the end, True Sustainability performance of the target facility was improved by 2.37 base points, while economic and environmental performance was increased from being a system weakness to achieving an acceptable index score benchmark of 8.41 and system strength level of 9.31, respectively. Social sustainability score increased by 2.02 base points as a function of better gender bias ratio. The financial performance of the system improved from a 33% loss to 46.23% profit in the post-improvement state. Reductions in CO₂ emissions (55.16%), energy consumption (50.31%), solid waste generation (72.03%), non-value-added-time (89.30%) and cost performance (64.77%) were other significant achievements of the study. In the end, SBT Framework was successfully validated at the facility level and target facility evolved into its leaner, cleaner and more responsible version of itself. Furthermore, manufacturing industries of all sorts are key stakeholders, which rely on universities to satisfy the demand for competent workforce. Society also expects universities to educate youth and contribute to their self-development by achieving both, scientific and intellectual knowledge saturation. To expand the contribution of the study to the body of knowledge in the fields of Sustainability and Modern Management techniques, an undergraduate level course curriculum that integrates modern management techniques and sustainability concepts with wood products industry dynamics was developed. Students’ pre- and post-education awareness of, and familiarity with sustainability, potential consequences of ignored sustainability issues, modern management techniques, global trends, innovation waves, and industry evolution were compared through a seventeen-question survey. Results showed that course content was successful at increasing sustainability awareness at both overall and individual sustainability pillar levels, At the end, 100% of students were able to develop complete understanding of various modern management techniques and stated that they felt confident to apply learnt skills to real life issues within their profession upon graduation. Overall, this study empirically documented how synergies between Lean, Sustainability, Six-Sigma and Life Cycle Assessment concepts outweigh their divergences, demonstrated viability of SBT Framework and presented a proven example of modern management techniques powered transdisciplinary sustainability curriculum.</a>
