摘要

在干旱森林生态系统中工作的森林管理者必须面对火灾的成本和收益,他们正在寻求森林管理策略,以增强森林和地貌在不断变化的气候中抵御未来干扰的能力。一个跨学科科学团队与资源管理人员和利益相关者合作,根据潜在的气候变化和管理策略,对加利福尼亚州和内华达州太浩湖盆地 23,000 公顷土地上未来的森林生态系统动态进行了评估,以支持太浩湖西部恢复合作项目。我们利用景观变化模型预测了森林的生长和火灾动态,科学团队在此基础上建立了其他模型,以评估野生动物栖息地、水和经济的变化。管理人员和利益相关者利用这一综合建模工作的结果,为景观恢复战略的设计提供了信息,该战略在坚实的科学基础上平衡了风险和收益。本特刊发表的研究结果表明,与更积极、更广泛的管理方法相比,继续维持现状的管理方法在保护和改善预期成果方面的效果较差。此外,管理活动的类型也会影响生态系统的结果。本特辑中各项研究的结果表明,疏伐和规定用火是相辅相成的,尽管它们产生的效果略有不同,而且低强度用火对生态系统产生的益处最多、幅度最大。一个明显的例外是碳储量,碳储量随着更积极的管理,特别是明火的使用而减少。我们重点介绍了本专题的主要发现,并总结了我们在共同生产科学方面面临的主要挑战和吸取的一些经验教训。简而言之,科学-管理伙伴关系需要合作、耐心和技巧,但它们能有效提高土地管理者在快速变化和不确定性增加的环境中的驾驭能力。

Keeping up with the landscapes: promoting resilience in dynamic social-ecological systems

Forest managers working in dry forest ecosystems must contend with the costs and benefits of fire, and they are seeking forest management strategies that enhance the resilience of forests and landscapes to future disturbances in a changing climate. An interdisciplinary science team worked with resource managers and stakeholders to assess future forest ecosystem dynamics, given potential climatic changes and management strategies, across a 23,000-ha landscape in the Lake Tahoe basin of California and Nevada in support of the Lake Tahoe West Restoration Partnership. We projected forest growth and fire dynamics using a landscape change model, upon which the science team layered additional modeling to evaluate changes in wildlife habitat, water, and economics. Managers and stakeholders used the findings of this integrated modeling effort to inform the design of a landscape restoration strategy that balanced risks and benefits based on a robust scientific foundation. The results, published in this Special Feature, suggest that a continuation of status quo management would be less effective at protecting and improving desired outcomes than more active and extensive management approaches. In addition, the types of management activity also affected ecosystem outcomes. Results from across the studies in this special feature suggest that thinning and prescribed fire were complementary, although they resulted in somewhat different effects, and that low-severity use of fire had the greatest array and magnitude of ecosystem benefits. A notable exception was carbon storage, which declined with more active management and prescribed fire in particular. We highlight key findings from this Special Feature and summarize key challenges and some lessons learned in our experience of co-producing science. In short, science-management partnerships require cooperation, patience, and skill, but they are effective in increasing the capacity of land managers to navigate in an environment of rapid change and increasing uncertainty.

The post Keeping up with the landscapes: promoting resilience in dynamic social-ecological systems first appeared on Ecology & Society.

期刊介绍: Ecology and Society is an electronic, peer-reviewed, multi-disciplinary journal devoted to the rapid dissemination of current research. Manuscript submission, peer review, and publication are all handled on the Internet. Software developed for the journal automates all clerical steps during peer review, facilitates a double-blind peer review process, and allows authors and editors to follow the progress of peer review on the Internet. As articles are accepted, they are published in an "Issue in Progress." At four month intervals the Issue-in-Progress is declared a New Issue, and subscribers receive the Table of Contents of the issue via email. Our turn-around time (submission to publication) averages around 350 days. We encourage publication of special features. Special features are comprised of a set of manuscripts that address a single theme, and include an introductory and summary manuscript. The individual contributions are published in regular issues, and the special feature manuscripts are linked through a table of contents and announced on the journal''s main page. The journal seeks papers that are novel, integrative and written in a way that is accessible to a wide audience that includes an array of disciplines from the natural sciences, social sciences, and the humanities concerned with the relationship between society and the life-supporting ecosystems on which human wellbeing ultimately depends.
