摘要

本期《牧场生态与管理》特刊致力于应用 "鼠尾草保护设计"(Sagebrush Conservation Design,SCD)来改善整个鼠尾草生物群落的保护成果,以应对普遍存在的生态系统威胁。本特刊提供了新的科学知识和实际案例,说明我们可以如何实施 SCD 来拯救一个生物群落。SCD 是一种工具,用于识别完整的鼠尾草地区并解决生态系统面临的最大威胁。SCD 的重点首先是保护完好无损且功能正常的沙棘生态系统(称为核心沙棘区),然后再向外扩展到退化较严重的地区(即 "保卫核心")。捍卫核心 "方法背后的前提很简单:首先将资源集中用于预防性行动,以保留核心灌木丛地区的生态系统服务,因为这些行动更具成本效益,也更有可能取得成功。本特刊的开篇文章为随后的 19 篇论文奠定了基础,为实施 SCD 提供了一条连贯的路径。首要主题是1)"一切照旧 "无法拯救沙棘海;2)更好的空间定位可改善结果;3)需要保护规划来制定现实的商业计划;4)有针对性的生态系统管理:4) 目标明确的生态系统管理:监测显示对灌木丛生态完整性的管理是有效的,5) 维护灌木丛生态完整性与生态相关,6) 只有管理变化才有希望。这些文章共同表明,目前还没有拯救该生物群落的共同计划,但该生物群落的商业计划可以确保实现现实的目标。鼠尾草生物群落仍然拥有广阔的开放空间,其生态完整性很高,这种规模在美国低48州的其他生态系统中非常罕见。如果我们关注生态系统变化主要驱动因素的共同点,实施 SCD 和捍卫核心是帮助拯救生物群落的可行战略。

State of the Sagebrush: Implementing the Sagebrush Conservation Design to Save a Biome
This special issue of Rangeland Ecology and Management is dedicated to applying the Sagebrush Conservation Design (SCD) to improve conservation outcomes across the sagebrush biome in the face of pervasive ecosystem threats. This special issue provides new science and real-world examples of how we can implement the SCD to save a biome. The SCD is a tool to identify intact sagebrush areas and address the largest threats to the ecosystem. The SCD focuses on first protecting intact and functioning sagebrush ecosystems, called Core Sagebrush Areas, then works outward toward more degraded areas (i.e., “Defend the Core”). The premise behind the Defend the Core approach is simple: focus resources first on preventative actions that retain ecosystem services in Core Sagebrush Areas because they are more cost-effective and more likely to be successful. The opening article of this special issue creates a foundation for the 19 following papers, providing a coherent path for implementing the SCD. The overarching themes are: 1) Business-As-Usual Won't Save the Sagebrush Sea, 2) Better Spatial Targeting Can Improve Outcomes, 3) Conservation Planning is Needed to Develop Realistic Business Plans, 4) Targeted Ecosystem Management: Monitoring Shows Managing for Sagebrush Ecological Integrity is Working, 5) Maintaining Sagebrush Ecological Integrity is Ecologically Relevant, and 6) There is Only Hope if We Manage Change. The collective articles show that there is no shared plan to save the biome, yet a business plan for the biome could ensure realistic goals. The sagebrush biome still has vast expanses of open spaces with high ecological integrity at a scale that is rare in other ecological systems within the lower 48 states. If we focus on the common ground of the main drivers of ecosystem change, implementing the SCD and Defending the Core are viable strategies to help save a biome.

期刊介绍: Rangeland Ecology & Management publishes all topics-including ecology, management, socioeconomic and policy-pertaining to global rangelands. The journal''s mission is to inform academics, ecosystem managers and policy makers of science-based information to promote sound rangeland stewardship. Author submissions are published in five manuscript categories: original research papers, high-profile forum topics, concept syntheses, as well as research and technical notes. Rangelands represent approximately 50% of the Earth''s land area and provision multiple ecosystem services for large human populations. This expansive and diverse land area functions as coupled human-ecological systems. Knowledge of both social and biophysical system components and their interactions represent the foundation for informed rangeland stewardship. Rangeland Ecology & Management uniquely integrates information from multiple system components to address current and pending challenges confronting global rangelands.
