The changes in native forest and grassland management regimes following European settlement, particularly fire exclusion, have prompted the growth of fire intolerant woody tree species such as eastern redcedar (Juniperus virginiana). Eastern redcedar is a native species that has encroached into the prairies and forests of the southern Great Plains of the United States. Over the past few decades, the state of Oklahoma has witnessed considerable ecological and economic losses due to the widespread encroachment of eastern redcedar. This study performed an economic impact analysis in conjunction with a spatial analysis to understand the impacts of the introduction of new eastern redcedar-based bioproducts industries on the economy of Oklahoma. The results suggested that the new eastern redcedar industry manufacturing particleboard, mulch, and oil would contribute an additional USD 96 million per year to the economy of Oklahoma, while generating 319 employment opportunities. In addition, the spatial analysis identified two hotspot clusters suggesting that the existing biomass in the northwest and southeast counties of the state could sustain the bioproducts industry for two to ten decades based on the annual feedstock requirement of different operations.

欧洲定居后当地森林和草地管理制度的变化，特别是防火禁令的变化，促使耐火木本树种的生长，例如东部雪松（Juniperus virginiana）。东部柳杉是一种本土物种，已侵入美国南部大平原的草原和森林。在过去的几十年中，由于东部红杉的广泛入侵，俄克拉荷马州遭受了相当大的生态和经济损失。这项研究结合空间分析进行了经济影响分析，以了解引入新的东部基于红杉的生物制品产业对俄克拉荷马州经济的影响。结果表明，新的东部红杉产业制造刨花板，覆盖物和石油每年将为俄克拉荷马州的经济贡献额外的9,600万美元，同时创造319个就业机会。此外，
