Operating as ecological engineers, the increased distribution and abundance of wild hogs (Sus scrofa) has caused considerable socio-economic impacts. The international scope of economic research providing wild hog damage estimates are often confined to agricultural crops, while damage estimates among forest plantations are lacking. In Alabama, private landowners hold the majority of timberland acreage and are less equipped to absorb financial losses from wild hog damage than their industrial counterparts. A survey was conducted to estimate the economic impact of wild hogs, namely costs of damage and control, to privately owned forestlands. The survey was distributed in the summer of 2016 to a sample of 1160 private landowners across the State. A 35% response rate was achieved from the sampled group. Survey results indicated in 2013 to 2015 longleaf pine (Pinus palustris) and loblolly pine (Pinus taeda) were the only species damaged by wild hogs. Wild hogs caused damage to 34 and 13% of forest acres in longleaf and loblolly plantations, respectively. At $50.40 per acre, costs associated with replanting damaged longleaf acres were double those for loblolly. Survey results suggest the southern half of Alabama holds the largest wild hog populations and sustained the most damage to forest stands. Consequently, landowners in this region invested the most capital on control methods where the average cost per control technique ranged from $12–2750. Additionally, landowners who did not have wild hogs on their property were willing to pay around $14 per acre more for eradication than those with. We hope the findings from this survey will provide a better understanding of the economic impact of wild hogs in young forest plantations.

阿拉巴马州幼林野猪危害与防治的经济估算。

作为生态工程师,野猪的分布和数量不断增加(Sus scrofa)引起了相当大的社会经济影响。提供野猪危害估算的国际经济研究范围通常仅限于农作物,而缺少森林人工林的危害估算。在阿拉巴马州,私人土地所有者拥有大部分林地面积,与工业同行相比,他们没有能力承担因野猪损害而蒙受的经济损失。进行了一项调查,以估算野猪对私有林地的经济影响,即破坏和控制的成本。该调查于2016年夏季分发给全州1160名私人土地所有者。抽样组的回应率达到35%。调查结果显示,2013年至2015年,长叶松(Pinus palustris)和火炬松(Plus palustris大松)是唯一受野猪破坏的物种。野猪分别对长叶和火炬松人工林造成34%和13%的森林面积造成破坏。以每英亩50.40美元的价格,与受损长叶英亩的种植相关的成本是火炬树的两倍。调查结果表明,阿拉巴马州的南半部拥有最大的野猪种群,对林分的破坏最大。因此,该地区的土地所有者在控制方法上投入了最多的资金,而每种控制技术的平均成本在12到2750美元之间。此外,那些土地上没有野猪的土地所有者愿意为每英亩土地多付14美元,以消灭土地。我们希望本次调查的结果能更好地了解野猪对人工林的经济影响。
