ABSTRACT Harvesting timber in forests recently affected by a disturbance, i.e. in salvage conditions, is generally thought to take longer and come at a greater cost compared to harvesting non-salvage timber. Despite this, the degree that forest disturbances create stand conditions that impact productivity when harvesting salvage timber has not been quantified. Similarly, the concerns and perceptions loggers have when operating in salvage conditions have not been fully assessed. This analysis examined mailed survey responses from 129 logging business owners from the state of Minnesota, USA, which inquired about their experience in harvesting timber from salvage sales, concerns about operating under salvage conditions, and perceptions of productivity in forests impacted by three common disturbances. In total, 41.9% of logging business owners (n = 54) indicated they harvested wood from at least one salvage sale in 2015 or 2016. The majority of loggers cited concerns with reduced productivity and reduced wood quality when operating under salvage conditions. Using multinomial logistic regression, analyses indicate logging business owners would have a greater probability of conducting a salvage sale if they produced more volume, were in business for fewer years, and produced a greater percentage of volume during the summer months. As managing for natural disturbances are increasingly being incorporated into forest management plans, forestry professionals should consider these results in response to relatively discrete disturbance events and how salvage sales are designed.

伐木者对美国明尼苏达州打捞收获的看法

摘要 在最近受到干扰影响的森林中采伐木材,即在抢救条件下,与采伐非抢救木材相比,通常被认为需要更长的时间并且成本更高。尽管如此,尚未量化森林干扰造成的林分条件在收获回收木材时影响生产力的程度。同样,记录员在打捞条件下工作时的担忧和看法也没有得到充分评估。该分析检查了来自美国明尼苏达州的 129 位伐木企业主的邮寄调查回复,这些回复询问了他们从回收销售中收获木材的经验、对在回收条件下运营的担忧以及对受三种常见干扰影响的森林生产力的看法。共计 41 个。9% 的伐木企业主 (n = 54) 表示,他们在 2015 年或 2016 年至少从一次打捞销售中收获了木材。大多数伐木者表示担心在打捞条件下作业时生产力降低和木材质量下降。使用多项逻辑回归分析表明,如果伐木企业主产量更大、经营年限更短,并且在夏季月份的产量百分比更大,那么伐木企业主就有更大的可能性进行打捞销售。随着对自然干扰的管理越来越多地被纳入森林管理计划,林业专业人员应该考虑这些结果以应对相对离散的干扰事件以及如何设计救助销售。大多数伐木者都提到了在打捞条件下作业时生产力下降和木材质量下降的担忧。使用多项逻辑回归,分析表明,如果伐木企业主产量更多,经营年限更短,并且在夏季月份的产量百分比更大,那么伐木企业主就有更大的可能性进行打捞销售。随着对自然干扰的管理越来越多地被纳入森林管理计划,林业专业人员应该考虑这些结果以应对相对离散的干扰事件以及如何设计救助销售。大多数伐木者都提到了在打捞条件下作业时生产力下降和木材质量下降的担忧。使用多项逻辑回归,分析表明,如果伐木企业主产量更多,经营年限更短,并且在夏季月份的产量百分比更大,那么伐木企业主就有更大的可能性进行打捞销售。随着对自然干扰的管理越来越多地被纳入森林管理计划,林业专业人员应该考虑这些结果以应对相对离散的干扰事件以及如何设计救助销售。分析表明,如果伐木企业主产量更多,经营年限更少,并且在夏季月份的产量百分比更高,那么伐木企业主就有更大的可能性进行打捞销售。随着对自然干扰的管理越来越多地被纳入森林管理计划,林业专业人员应该考虑这些结果以应对相对离散的干扰事件以及如何设计救助销售。分析表明,如果伐木企业主产量更多,经营年限更少,并且在夏季月份的产量百分比更高,那么伐木企业主就有更大的可能性进行打捞销售。随着对自然干扰的管理越来越多地被纳入森林管理计划,林业专业人员应该考虑这些结果以应对相对离散的干扰事件以及如何设计救助销售。
