CNH-Ex: Ecology, Culture, and Outcomes: Linking Human Perceptions and Socio-Ecological Thresholds for Ecosystem Restoration (ECO-Link)

有效的生态系统管理需要采取综合研究方法，以确定人类与自然系统之间的联系。为了填补这一空白，ECO-Link正在评估影响管理入侵的北美海狸和恢复南美洲南部河岸森林的社会和生态阈值和反馈。是火地岛群岛。我们假设，目前缺乏当地参与生态系统管理举措的影响，破碎的激励结构，不占反馈之间的基本信念生态系统服务的提供及其对社会福祉的影响。在环境管理中，将不作为与行动分开的门槛可以通过明确地将这些潜在的信念和影响融入有效的激励计划的设计中来克服。我们将使用一套方法来测试我们的假设，i）研究土地所有者和其他利益相关者对自然的看法和信念，以及促进或限制决策和行动的过程和影响; ii）研究激励计划的潜力，以提高生态系统管理的参与; iii）量化海狸控制和重新造林工作前后的相关生态系统服务;在智利和阿根廷的不同土地使用权下，将感知、激励和生态系统服务整合到一个大的景观中。1946年，北美海狸被引入火地岛群岛，它是自上一次冰川消退以来巴塔哥尼亚南部森林最大的生态系统变化的原因。海狸的扩张导致了广泛的森林砍伐和整个河流生态系统的水文变化，自2006年以来，智利，阿根廷和美国的机构一直在合作应对这个问题。然而，很明显，要阻止这种生态破坏的蔓延和恢复集水区，就需要有一个涉及私人和公共土地所有者的大规模综合管理计划。目前正在考虑实施奖励方案，明确鼓励私人土地所有者改变行为，以取得积极的环境成果。在阿根廷和智利共享的火地岛，了解当地土地所有者对入侵物种和生态系统服务之间联系的看法，对于设计一个有效的方案，促进跨越国际机构界限的参与和环境管理至关重要。通过关注生态、文化和管理行动结果之间关系的重要研究问题，ECO-Link在恢复和保护南美洲南部巴塔哥尼亚森林的努力中发挥着重要作用。世界上最珍贵的荒野之一

Effective ecosystem management requires an integrated research approach to determine the links between human and natural systems. To fill this gap, ECO-Link is assessing the social and ecological thresholds and feedbacks that influence efforts to manage the invasive North American beaver and restore riparian forests in southern South America?s Tierra del Fuego Archipelago. We hypothesize that a current lack of local participation in ecosystem management initiatives is influenced by broken incentive structures that do not account for feedbacks between the underlying beliefs about ecosystem service delivery and their impacts on social well-being. The thresholds that separate inaction from action in environmental stewardship can be overcome by explicitly integrating these underlying beliefs and impacts into to the design of effective incentive programs. We will use a suite of approaches to test our hypothesis by i) studying the perceptions and beliefs of nature held by landowners and other stakeholders, as well as the processes and influences that facilitate or constrain decision-making and action; ii) examining the potential for incentive programs to improve participation in ecosystem management; iii) quantifying associated ecosystem services before and after beaver control and reforestation efforts; and iv) integrating perceptions, incentives, and ecosystem services across a large landscape under various land tenures in Chile and Argentina.Introduced to the Tierra del Fuego Archipelago in 1946, the North American beaver is responsible for the largest landscape-level change to these southern Patagonian forests since the retreat of the last glaciation. The beaver's expansion has caused widespread deforestation and hydrological changes to entire river ecosystems, and since 2006, Chilean, Argentine and U.S. institutions have been collaborating to confront the issue. It is clear, however, that halting the spread of this ecological damage and restoring watersheds will require a large-scale, integrated management plan involving private and public landowners. Incentive programs are being considered to explicitly encourage behavioral changes in private landowners with the goal of positive environmental outcomes. In Tierra del Fuego, which is shared between Argentina and Chile, understanding local landowners' perceptions of the links between invasive species and ecosystem services is critical to designing an effective program that promotes participation and environmental stewardship across international institutional boundaries. By focusing on important research questions at the nexus of ecology, culture, and outcomes of management actions, ECO-Link is playing an important role in efforts to restore and protect the southern Patagonian forests of South America?one of the world's most cherished wilderness areas.
