Forest-grassland ecotones are a mosaic of grassland, savanna, and upland forest. As such, landowners may have opportunities to choose to manage their lands for multiple objectives. We estimated the economic returns from managing forest and rangeland in southeastern Oklahoma, USA to produce different combinations of timber, cattle forage, and white-tailed deer (Odocoileus virginianus Zimmermann) browse for a 40-year period. We further conducted a survey to understand landowner perceptions of obstacles to adopting active management that involve timber harvest and prescribed fire. The highest net return was obtained from the treatment with harvested timber that was burned every four years (uneven-aged woodland/forest) because it had the greatest gross return from a combination of timber (46%), cattle forage (42%), and deer browse (11%). The return from this treatment was greater than that for managed for timber only (closed-canopy forest) or prioritizing cattle and deer (savanna). Survey results suggested that landowners were aware of the benefits of active management but that the majority (66%) considered cost a major obstacle in the management of their forest or rangeland. In particular, women forestland owners and older landowners considered cost an obstacle. Our findings advocate integrated timber, cattle, and deer management as the best economic strategy within the forest-grassland ecotone and for targeted outreach and landowner education related to the benefits of active management.
森林-草原交错带是草原、稀树草原和山地森林的镶嵌体。因此,土地所有者可能有机会选择为多个目标管理其土地。我们估计了美国俄克拉荷马州东南部的森林和牧场管理的经济回报,以在 40 年内生产不同组合的木材、牛饲料和白尾鹿(Odocoileus virginianus Zimmermann)饲料。我们还进行了一项调查,以了解土地所有者对涉及木材采伐和计划火烧的主动管理的障碍的看法。从每四年采伐一次并燃烧的木材(不均匀林龄林地/森林)中获得的净回报最高,因为它从木材(46%)、牛饲料(42%)和鹿饲料(11%)的组合中获得了最大的总回报。这种处理的回报大于仅管理木材(封闭树冠森林)或优先考虑牛和鹿(稀树草原)的处理。调查结果表明,土地所有者意识到主动管理的好处,但大多数(66%)认为成本是其森林或牧场管理的主要障碍。特别是,女性林地所有者和老年土地所有者认为成本是一个障碍。我们的研究结果主张在森林-草原交错带内进行综合的木材、牛和鹿管理,这是最佳的经济策略,并针对与主动管理的好处相关的目标外联和土地所有者教育。
