Marine Corps Base Camp Lejeune Geospatial Marsh Model: Habitat Maps

Critical military training and testing on lands along the nation’s coastal and estuarine shorelines are increasingly placed at risk because of encroachment pressures in surrounding areas, impairments due to other anthropogenic disturbances, and changes in climate and sea level. The U.S. Department of Defense (DoD) intends to enhance and sustain its training and testing assets and also optimize its stewardship of natural resources through the development and application of an ecosystem-based management approach on DoD installations. To accomplish this goal, particularly for installations in estuarine/coastal environments, the Strategic Environmental Research and Development Program (SERDP) launched the Defense Coastal/Estuarine Research Program (DCERP) as a 10-year effort at Marine Corps Base Camp Lejeune (MCBCL) in North Carolina. The results of the second 5 years of the program (DCERP2) are presented in the DCERP2 Final Report. There were four overarching objectives of DCERP2. The first objective was to understand the effects of climate change impacts, including warming temperatures, variability in the hydrological cycle, storm events, and sea level rise on the coastal ecosystems at MCBCL from observations and measurements made over the 10-year program. The second objective was to understand the carbon cycle of the coastal and terrestrial ecosystems at MCBCL through a highly integrated sampling program. The third objective was to develop models, tools, and indicators to evaluate current and projected future ecosystem state changes and translate scientific findings into actionable information for installation managers. The last objective was to recommend adaptive management strategies to sustain ecosystem natural resources within the context of an active military installation. This data package contains PNGs (images) of habitat maps (key is provided as single PNG) for Freeman, Traps, and French marsh modeling domains in the target years 2013 (initial), 2035, 2065, & 2100 after modeling marsh under the five SLR scenarios provided by the base.美国沿海与河口沿岸地带的重要军事训练与测试活动正日益面临风险，其诱因包括周边区域的侵占压力、其他人为活动造成的生态破坏，以及气候与海平面变化。美国国防部（Department of Defense, DoD）旨在通过在其军事设施中开发并应用基于生态系统的管理模式，强化并维持其训练与测试资产，同时优化对自然资源的管护工作。为实现这一目标，尤其是针对河口/沿海环境中的军事设施，战略环境研究与发展计划（Strategic Environmental Research and Development Program, SERDP）启动了国防沿海/河口研究计划（Defense Coastal/Estuarine Research Program, DCERP），该计划为期十年，落地于北卡罗来纳州的勒琼海军陆战队基地（Marine Corps Base Camp Lejeune, MCBCL）。该计划第二个五年阶段（DCERP2）的研究成果收录于《DCERP2最终报告》中。DCERP2共设有四项核心目标：第一项目标为基于十年计划期间的观测与测量数据，解析气候变化（包括气温升高、水文循环波动、风暴事件以及海平面上升）对勒琼海军陆战队基地沿海生态系统的影响；第二项目标为通过高度集成的采样计划，厘清勒琼海军陆战队基地沿海与陆地生态系统的碳循环过程；第三项目标为开发用于评估当前及预测未来生态系统状态变化的模型、工具与指标体系，并将科研成果转化为可供军事设施管理者使用的可落地决策信息；第四项目标为针对现役军事设施的运营场景，提出可持续管护生态系统自然资源的适应性管理策略。本数据包包含针对Freeman、Traps与French沼泽模拟区域的生境地图（含单张PNG格式图例），模拟场景基于该基地提供的五种海平面上升（Sea Level Rise, SLR）情景，覆盖目标年份2013年（初始基准年）、2035年、2065年与2100年的沼泽模拟结果。
