Abstract

Previous studies have advanced the conceptual framing of a “supply chain” to describe and examine key steps, inputs, and flows related to the production and use of seed and plant material in ecological restoration. However, these studies have paid less attention to investigating interrelationships among social actors throughout the “supply chain” stages for ecological restoration and allied activities. We applied social network analysis metrics to evaluate the number, kind, and strength of relationships among 157 social actors in the nine‐state region of the Northeastern United States, where rapid growth in restoration activities is driving a demand surge for native seed and plant materials. Restoration supply chains are more complex than previous conceptualization suggests, and we argue that the term “restoration supply networks” is more illustrative of this complexity. Results highlighted interdependency among different sectors, marked variation in input and output flows across spatial–temporal scales, and interplay among linear and nonlinear supply chain steps. The restoration supply network in the study area had a core–periphery structure, with a core comprising end‐users such as government agencies, design and build contractors, and non‐profit organizations surrounded by a periphery of seed and plant material suppliers. It is important to avoid oversimplifying seed and plant material supply chains as linear systems with strong linkages. Understanding relationship patterns among supply network actors can enhance communication, coordination, and collaboration among actors in all key restoration supply chain steps, a prerequisite to overcoming seed and plant material bottlenecks and meeting global restoration goals in the coming decades.
修复种子和植物材料供应链是复杂的社会网络
以往的研究推进了 "供应链 "的概念框架,以描述和研究与生态恢复中种子和植物材料的生产和使用相关的关键步骤、投入和流动。然而,这些研究较少关注调查生态恢复和相关活动的整个 "供应链 "阶段中社会参与者之间的相互关系。我们运用社会网络分析指标,评估了美国东北部九州地区 157 个社会参与者之间关系的数量、种类和强度,该地区恢复活动的快速增长推动了对本地种子和植物材料需求的激增。恢复供应链比以往概念化的供应链更为复杂,我们认为 "恢复供应网络 "一词更能说明这种复杂性。研究结果突显了不同部门之间的相互依存关系、不同时空尺度上输入和输出流量的显著差异以及线性和非线性供应链步骤之间的相互作用。研究区域的恢复供应网络具有核心-外围结构,核心包括政府机构、设计和施工承包商以及非营利组织等最终用户,外围是种子和植物材料供应商。重要的是,要避免将种子和植物材料供应链过度简化为具有紧密联系的线性系统。了解供应网络参与者之间的关系模式可以加强修复供应链所有关键步骤中参与者之间的沟通、协调与合作,这是克服种子和植物材料瓶颈、实现未来几十年全球修复目标的先决条件。

期刊介绍: Restoration Ecology fosters the exchange of ideas among the many disciplines involved with ecological restoration. Addressing global concerns and communicating them to the international research community and restoration practitioners, the journal is at the forefront of a vital new direction in science, ecology, and policy. Original papers describe experimental, observational, and theoretical studies on terrestrial, marine, and freshwater systems, and are considered without taxonomic bias. Contributions span the natural sciences, including ecological and biological aspects, as well as the restoration of soil, air and water when set in an ecological context; and the social sciences, including cultural, philosophical, political, educational, economic and historical aspects. Edited by a distinguished panel, the journal continues to be a major conduit for researchers to publish their findings in the fight to not only halt ecological damage, but also to ultimately reverse it.
