In this article, we respond to a critique of our earlier work examining the USDA Forest Service’s (USFS’s) planning processes. We appreciate that our critics introduce new data to the discussion of USFS planning. Further data integration is a promising path to developing a deeper understanding of agency activities. Our critics’ analysis largely supports our original claims. Our most important difference is in our conceptualization of the planning process’s relationship to agency goals. Although our critics conceive of the USFS’s legally prescribed planning processes as a barrier to land management activities, we believe that public comment periods, scientific analysis, and land management activities are tools the agency uses to achieve its goals of managing land in the public interest. Study Implications: The USDA Forest Service’s current planning process has been critiqued as a barrier to accomplishing land management activities, but it is also an important tool for insuring science-based management and understanding public values and interests that the agency is legally bound to uphold.
在这篇文章中,我们回应了对我们早期研究美国农业部林业局(USFS)规划过程的工作的批评。我们感谢我们的批评者在讨论USFS计划时引入了新的数据。进一步的数据整合是加深对机构活动了解的一条有希望的途径。我们的批评者的分析在很大程度上支持了我们最初的主张。我们最重要的区别在于我们对规划过程与机构目标之间关系的概念化。尽管我们的批评者认为美国农业部法律规定的规划过程是土地管理活动的障碍,但我们相信,公众评论期、科学分析和土地管理活动是该机构用来实现其公共利益管理土地目标的工具。研究启示:美国农业部林业局目前的规划过程被批评为完成土地管理活动的障碍,但它也是确保基于科学的管理和理解该机构在法律上必须维护的公共价值和利益的重要工具。

Collaboration is increasingly emphasized as a tool to realize national-level policy goals in public lands management. Yet, collaborative governance regimes (CGRs) are nested within traditional bureaucracies and are affected by internal and external disruptions. The extent to which CGRs adapt and remain resilient to these disruptions remains under-explored. Here, we distill insights from an assessment of the Collaborative Forest Landscape Restoration Program (CFLRP) projects and other CGRs. We asked (1) how do CGRs adapt to disruptions? and (2) what barriers constrained CGR resilience? Our analysis is informed by a synthesis of the literature, case examples and exemplars from focus groups, and a national CFLRP survey. CGRs demonstrated the ability to mobilize social capital, learning, resources, and flexibility to respond to disruptions. Yet authority, accountability, and capacity complicated collaborative resilience. We conclude with policy and practice recommendations to cultivate collaborative resilience moving forward. Collaborative approaches between public lands management agencies and nongovernment organizations have become common in forest restoration. Yet collaborative progress may be affected by turnover, wildfire disturbances, or legal or policy changes. We assessed how forest collaboratives in the United States adapted to changes that affected their performance and documented the factors that constrained response. We found that forest collaboratives developed myriad strategies to adapt to these changes, although limited authority, capacity, and accountability constrain adaptation options. We offer policy and practice recommendations to overcome these constraints, increase adaptation options, and enhance the sustainability of forest collaboratives.
作为实现国家一级公共土地管理政策目标的工具,合作日益受到重视。然而,协作治理制度(cgr)嵌套在传统的官僚机构中,并受到内部和外部干扰的影响。cgr在多大程度上适应并保持对这些破坏的弹性仍未得到充分探索。在此,我们从合作森林景观恢复计划(CFLRP)项目和其他cgr项目的评估中提取了一些见解。我们问(1)cgr如何适应中断?(2)制约CGR恢复能力的障碍是什么?我们的分析综合了文献、案例和焦点小组的范例,以及全国CFLRP调查。cgr展示了动员社会资本、学习、资源和灵活性以应对中断的能力。然而,权威、责任和能力使协作弹性变得复杂。最后,我们提出了政策和实践建议,以培养未来的协作弹性。公共土地管理机构和非政府组织之间的合作方式在森林恢复中已经变得普遍。然而,合作进程可能受到人员更替、野火干扰或法律或政策变化的影响。我们评估了美国的森林合作者如何适应影响其绩效的变化,并记录了制约其反应的因素。我们发现,森林合作组织制定了无数适应这些变化的战略,尽管有限的权力、能力和问责制限制了适应选择。我们提出了政策和实践建议,以克服这些制约因素,增加适应选择,并增强森林合作的可持续性。

Virtually all states have developed best management practices (BMPs) to mitigate potential adverse effects associated with timber harvesting. This study examined how BMP implementation on Minnesota’s family forest lands varied according to whether the land had a forest management plan, the timber sale was administered by a forester, or a written timber harvesting contract was used. Analysis of field monitoring data from 174 commercial timber harvesting sites on family forest lands found that BMP implementation is only modestly influenced by a forest management plan, supervising forester, or timber harvesting contract. Supervision of a forester had the greatest influence, with six guidelines implemented differently. In contrast, differences were found for just two BMPs with a forest management plan and only one with a written timber harvesting contract. When timber sales were administered by a forester, forest management guidelines generally related to management of the land-water interface were implemented to a higher standard, with significant increases observed for avoidance of infrastructure in filter strips, use of water diversion and erosion control structures, avoiding unnecessary wetland and waterbody crossings, and slash management. Higher timber utilization efficiency (within leave tree guidelines) was also found when a professional forester supervised the timber sale. Study Implications: We examine how BMP implementation on family forest lands varies with three types of supervisory and planning assistance: a forest management plan for the property, sale administration by a professional forester, and a written timber harvesting contract. Field monitoring data from 174 commercial timber harvests on family forest lands indicate that BMP implementation is only modestly influenced by any single form of assistance. Supervision by a forester had the greatest influence, increasing use of four guidelines related to management of the land-water interface. Results may help to inform best practices for landowner assistance and planning.
几乎所有州都制定了最佳管理规范(BMPs),以减轻与木材采伐相关的潜在不利影响。这项研究考察了明尼苏达州家庭林地上BMP的实施如何根据土地是否有森林管理计划、木材销售是否由护林员管理或使用书面木材采伐合同而变化。对家庭林地上174个商业木材采伐点的现场监测数据的分析发现,BMP的实施仅受到森林管理计划、监督林务员或木材采伐合同的轻微影响。对护林员的监督影响最大,有六项指导方针的实施方式不同。相比之下,只有两个bmp有森林管理计划,只有一个有书面木材采伐合同。当木材销售由一名护林员管理时,一般与陆地-水界面管理有关的森林管理准则得到了更高标准的执行,在避免过滤带的基础设施、使用引水和侵蚀控制结构、避免不必要的湿地和水体交叉以及砍伐管理方面观察到显著增加。在专业林务员监督木材销售的情况下,还发现木材利用效率更高(在树叶树准则范围内)。研究意义:我们研究了家庭林地在三种监督和规划援助下BMP实施的不同:财产的森林管理计划、专业护林员的销售管理和书面木材采伐合同。来自174个家庭林地商业木材采伐的实地监测数据表明,任何一种形式的援助对BMP实施的影响都不大。林务员的监督影响最大,增加了有关陆地-水界面管理的四项准则的使用。结果可能有助于为土地所有者援助和规划提供最佳实践。

Relationship Between Riparian Buffers and Terrestrial Wildlife in the Eastern United States 美国东部河岸缓冲带与陆生野生动物的关系
Pub Date : 2021-12-29 DOI: 10.1093/jofore/fvab067

When working forest stands are harvested, vegetated strips along streams are often retained as part of forestry best management practices (BMPs) to protect water quality. These riparian buffers, known as streamside management zones, when following forestry BMP recommendations, also likely provide benefits to various terrestrial wildlife species. To better understand the role of riparian buffers in contributing to biological diversity in working forest landscapes, we reviewed literature (n = 30) that reported on herpetofauna, bird, and mammal responses to riparian buffers in the eastern United States. Although few results were consistent among taxa, community composition commonly varied among riparian buffer widths. Narrower riparian buffers more commonly supported edge and disturbance-associated species whereas wider riparian buffers tended to support interior-associated species. We did not find a consistent width that supported all terrestrial wildlife species studied. Study Implications: Based on our findings, it may be most efficacious to use varying riparian buffer widths across a landscape to provide structural conditions for a diversity of wildlife species. Some interior species may be best conserved on older managed stands or other retained areas in the landscape rather than riparian buffers. Landscape context and functionality of riparian buffers as movement corridors need to be further investigated, as this is an assumed but not quantified indirect benefit for various terrestrial wildlife species and perhaps especially important for species with low vagility or low dispersal ability that require older forest or riparian areas.
当工作林分被采伐时,沿着溪流的植被带通常被保留下来,作为林业最佳管理实践(BMPs)的一部分,以保护水质。这些河岸缓冲地带被称为河滨管理区,当遵循林业BMP的建议时,也可能为各种陆地野生动物物种提供好处。为了更好地理解河岸缓冲带对森林景观生物多样性的作用,我们回顾了美国东部关于爬行动物、鸟类和哺乳动物对河岸缓冲带响应的文献(n = 30)。虽然不同分类群间的结果很少一致,但群落组成在不同的河岸缓冲带宽度之间普遍存在差异。较窄的河岸缓冲带通常支持边缘和干扰相关物种,而较宽的河岸缓冲带倾向于支持内部相关物种。我们没有发现一个一致的宽度支持所有陆地野生动物物种的研究。研究启示:根据我们的研究结果,在景观中使用不同的河岸缓冲宽度可能是最有效的,为野生动物物种的多样性提供结构条件。一些室内物种可能最好保存在较旧的管理林分或其他景观中保留的地区,而不是河岸缓冲带。河岸缓冲带作为运动走廊的景观背景和功能需要进一步调查,因为这是对各种陆生野生动物物种的一种假设但未量化的间接效益,对于那些需要较老的森林或河岸地区的低易变性或低扩散能力的物种来说可能尤其重要。

Innovation and knowledge exchange are critical to foster adaptive management and continual learning. Across the spectrum of knowledge exchange, ranging from peer-reviewed research to anecdotes, there is a largely untapped middle ground: real-world silvicultural case studies implemented and documented by foresters. The University of Minnesota Great Lakes Silviculture Library is a novel, freely available platform designed to enable foresters to exchange these case studies. Five years after its launch, we conducted focus groups with foresters from Minnesota and Wisconsin, USA, and Ontario, Canada, to explore the platform’s usage and value. Participants valued having access to examples of silvicultural treatments and their outcomes that they could easily digest, apply, and share. They gained new knowledge from management across administrative boundaries. They also appreciated the consistent, relatable case study format. However, participants noted that limited time was the primary barrier to wider authorship and readership. The Library enables information exchange across agencies and disciplines within natural resources, giving greater voice to practicing foresters and supplementing other sources of forestry knowledge. In our experience, foresters have always valued opportunities to exchange ideas and anecdotes about silvicultural treatments. Case studies represent one way for foresters to communicate with each other and continue to learn by seeing a variety of silvicultural prescriptions implemented on the landscape. Documenting treatments and the supporting reasoning allows foresters to share lessons learned over the course of their career with others across administrative boundaries. Normalizing this documentation can create a positive feedback loop for a case study platform in which further case study submissions lead to increased visibility, use, and perceived value of the platform. As the case study platform becomes more relevant to foresters, the forestry profession as a whole benefits from the long-term documentation of an increasingly diverse array of treatments.
创新和知识交流对于促进适应性管理和持续学习至关重要。在知识交流的各个领域,从同行评议的研究到奇闻轶事,有一个很大程度上尚未开发的中间地带:由林业工作者实施和记录的真实森林文化案例研究。明尼苏达大学五大湖森林文化图书馆是一个新颖的,免费提供的平台,旨在使林务人员能够交换这些案例研究。在推出五年后,我们与来自美国明尼苏达州和威斯康星州以及加拿大安大略省的林业人员进行了焦点小组讨论,以探索该平台的使用和价值。与会者重视获得他们可以轻松消化、应用和分享的造林治疗实例及其结果。他们从跨行政边界的管理中获得了新知识。他们还赞赏连贯、相关的案例研究形式。然而,与会者指出,有限的时间是扩大作者和读者的主要障碍。图书馆使各机构和学科之间能够在自然资源领域进行信息交流,使从事林业工作的人有更大的发言权,并补充其他林业知识来源。根据我们的经验,林务人员一直很重视交流关于造林治疗的想法和轶事的机会。案例研究是林务人员相互交流的一种方式,并通过在景观中实施各种造林处方来继续学习。记录处理方法和支持推理使森林管理员能够与跨行政边界的其他人分享其职业生涯中的经验教训。规范化该文档可以为案例研究平台创建一个积极的反馈循环,在这个循环中,进一步的案例研究提交可以提高平台的可见性、使用率和感知价值。随着案例研究平台与林农的关系越来越密切,林业行业作为一个整体受益于日益多样化的处理方法的长期记录。

Growth of Managed Older Douglas-fir Stands: Implications of the Black Rock Thinning Trial in the Coast Range of Western Oregon 经管理的老道格拉斯冷杉林分的生长:俄勒冈州西部海岸黑岩间伐试验的意义
Pub Date : 2021-12-13 DOI: 10.1093/jofore/fvab063

The most recent remeasurement of growth (at approximate total stand age 100 years) from the Black Rock Thinning Trial in western Oregon provides useful information for forest owners interested in accelerating restoration of older forest characteristics in Douglas-fir stands of the Pacific Northwest. Thinnings at several intensities at total stand age of roughly 50 years effectively reset stand growth patterns. With quadratic mean diameters in thinned plots up to 40% higher than those of unthinned controls, thinned plot mean annual increments (MAIs) and periodic annual increments continue to rise 55 years after thinning, with the peak in board foot and cubic foot MAI apparently still decades in the future. Assuming repeatable future thinning responses similar to the Black Rock Trial, financial analysis of the opportunity costs of extending rotations to 100 years indicates that some thinning treatments can reduce opportunity costs by up to half at a 6% discount rate. Active management through thinning may be a useful tool for public and private landowners interested in rapid development of stands with older forest characteristics to enhance output of some ecosystem services. Heavy thinning regimes, of the type described here, are compatible with growing trees with large diameter stems, large branches, and large crowns. They also reduce fuel accumulation by lowering mortality rates of stems less than 60 years old and slowing the rate of crown recession, branch mortality, and branch litterfall. Midrotation thinning revenues reduce opportunity costs of holding more rapidly growing stems to older ages, which may be a consideration for some owners.
俄勒冈州西部的黑岩间伐试验最近重新测量的生长(大约100年的总林龄)为森林所有者提供了有用的信息,这些森林所有者对加速恢复西北太平洋道格拉斯杉木林分的老森林特征感兴趣。在总林龄约为50年时,不同强度的间伐能有效地重置林分生长模式。减薄样地的二次平均直径比未减薄样地高出40%,减薄样地平均年增量(MAIs)和周期年增量在减薄后55年继续上升,板尺和立方尺MAI的峰值显然仍在未来几十年。假设未来可重复的间伐反应与Black Rock试验类似,将轮作延长至100年的机会成本的财务分析表明,以6%的贴现率,一些间伐处理可以将机会成本降低一半。对于有意迅速发展具有老森林特征的林分以提高某些生态系统服务产出的公共和私人土地所有者来说,通过间伐进行主动管理可能是一个有用的工具。此处描述的重度间伐制度适用于长有大直径茎、大树枝和大树冠的树木。它们还通过降低小于60年树龄的茎的死亡率和减缓树冠衰退、树枝死亡和树枝凋落物的速度来减少燃料的积累。中期轮换减少的收入减少了持有更快生长的茎到更长的时间的机会成本,这可能是一些所有者考虑的因素。

We conducted a spatially explicit vulnerability assessment of the forest industry in Maine, USA, to climate change in an effort to (1) advance a spatial framework for assessing forest industry vulnerability and (2) increase our understanding of Maine’s specific vulnerabilities to climate change in order to guide decision-making. We applied a bottom-up indicator approach to evaluate exposure, sensitivity, and adaptive capacity to climate change using both biophysical and social indicators, largely driven by participatory processes. Our approach enabled us to synthesize and aggregate indicators of regional importance to evaluate vulnerability, allowing us to simultaneously examine combinations of potential changes. We found that each Maine county had its own unique combination of exposure, sensitivity, and adaptive capacity indicators, with overall vulnerability highest in the rural northern and western parts of the state, where forest industry activities are most prevalent. However, results also indicate that although increased stress from climate-related changes can negatively affect Maine’s forest via high exposure, reduced sensitivities and increased adaptive capacity have the potential to largely decrease overall vulnerability in many parts of the state.
本文对美国缅因州森林产业的气候变化脆弱性进行了空间显式评估,旨在:(1)建立森林产业脆弱性评估的空间框架;(2)提高我们对缅因州气候变化脆弱性的认识,以指导决策。我们采用了一种自下而上的指标方法,利用生物物理和社会指标来评估对气候变化的暴露、敏感性和适应能力,主要由参与性过程驱动。我们的方法使我们能够综合和汇总具有区域重要性的指标来评估脆弱性,使我们能够同时检查潜在变化的组合。我们发现,缅因州的每个县都有自己独特的暴露、敏感性和适应能力指标组合,该州北部和西部农村地区的总体脆弱性最高,那里的森林工业活动最为普遍。然而,研究结果还表明,尽管气候相关变化带来的压力增加会对缅因州的森林产生负面影响,但降低敏感性和增加适应能力有可能在很大程度上降低该州许多地区的整体脆弱性。

Forest Contracting Businesses in the US Southwest: Current Profile and Workforce Training Needs 美国西南部的森林承包企业:现状和劳动力培训需求
Pub Date : 2021-11-22 DOI: 10.1093/jofore/fvab060

We surveyed forestry contractors in three sectors (logging, mastication, and trucking) across the states of Arizona, New Mexico, and Colorado. Our survey sought to gather current demographic and background information on contractors as well as establish how a forest operations training center might address their employee training needs. Most of the businesses surveyed were small, with owner ages tending to be high (over 50) but employee ages much lower (under 40). Finding skilled workers was identified as the greatest barrier to success by the respondents, underscoring the need for more training opportunities. The majority of respondents (86%) did not have access to any external training programs. Survey results indicated a high demand for training programs for forestry contractors in the Southwest, which could play a vital role for the region to achieve landscape-scale forest restoration goals.
我们调查了亚利桑那州、新墨西哥州和科罗拉多州三个部门的林业承包商(伐木、咀嚼和卡车运输)。我们的调查旨在收集有关承包商的当前人口统计和背景资料,并确定森林作业培训中心如何解决其雇员培训需要。大多数接受调查的企业规模较小,企业主年龄往往较高(50岁以上),但雇员年龄要低得多(40岁以下)。寻找熟练工人被受访者认为是成功的最大障碍,强调需要更多的培训机会。大多数受访者(86%)没有参加过任何外部培训项目。调查结果表明,西南地区对林业承包商培训项目的需求很大,这对该地区实现景观尺度的森林恢复目标至关重要。

New Hands in US Public Lands Management: The Role and Influence of Nonagency Partners in Forest Service Stewardship Agreements 美国公共土地管理的新手:非机构合作伙伴在森林服务管理协议中的作用和影响
Pub Date : 2021-11-22 DOI: 10.1093/jofore/fvab058

The USDA Forest Service (USFS) is increasingly turning to partnership tools such as stewardship agreements (SAs) to accomplish land management objectives. In these arrangements, nonagency partners (partners) often bring resources, capabilities, and preferences that can influence management processes and activities. We explored the nature of partner influence in SAs through interviews with USFS and partner staff in four SA case studies in Arizona, California, and New Mexico. Interviewees perceived that partners influenced project prioritization; implementation pace, scope, and approach; and SA participants’ ways of working. Influence was linked to partners’ involvement in SA project selection; contribution of resources, expertise, and capabilities; and assumption of some project implementation responsibilities. USFS-partner relationships also appeared to encourage partnership-oriented approaches beyond the original project. Our research suggests SA partners are uniquely influential in the implementation of USFS management activities and recommends additional exploration of SAs in the context of collaborative implementation.
美国农业部林业局(USFS)越来越多地转向伙伴关系工具,如管理协议(sa),以实现土地管理目标。在这些安排中,非代理伙伴(合作伙伴)经常带来可以影响管理过程和活动的资源、能力和偏好。在亚利桑那州、加利福尼亚州和新墨西哥州的四个SA案例研究中,我们通过对USFS和合作伙伴工作人员的采访,探讨了SA中合作伙伴影响的本质。受访者认为合作伙伴影响了项目的优先级;实施速度、范围和方法;以及SA参与者的工作方式。影响与合作伙伴参与SA项目选择有关;资源、专业知识和能力的贡献;并承担部分项目实施责任。usfs与合作伙伴的关系似乎也鼓励了在原始项目之外以伙伴关系为导向的方法。我们的研究表明,辅助服务伙伴在USFS管理活动的实施中具有独特的影响力,并建议在协作实施的背景下进一步探索辅助服务。

Serious games are designed to achieve specific educational or other practical purposes beyond pure entertainment. These games take many different forms—from card decks to massive multiplayer online games—and have proliferated across diverse fields. This note introduces IMPACT: Forestry Edition, a serious board game designed to help forestry professionals and stakeholders think more broadly, critically, and creatively about the future of forestry. We describe the game and feedback from beta testing and discuss the advantages and potential drawbacks of gaming methods. A “print and play” version of the game is included as supplemental material. Serious games can make an important contribution to forestry by engaging and informing diverse stakeholders and generating insight that other methods cannot.
