印度洋海啸使全世界的注意力集中在社会对环境危害的反应以及自然系统减轻干扰影响的潜力上。沿海地区对世界50%人口的福祉至关重要。美国南部的沿海系统适应热带气旋（飓风）和火灾的特定扰动机制。2005年8月和9月，卡特里娜飓风和丽塔飓风造成了美国历史上损失最惨重的自然灾害，其中仅风力造成的损失估计就达20亿至30亿美元。德克萨斯州、路易斯安那州、密西西比州和亚拉巴马等沿海各州共有223万公顷的廷伯兰受损。虽然经济损失估计是不完整的，但毫无疑问，这些飓风造成了广泛的破坏，其对景观的影响将持续多年。制定一项战略，将大规模的，不频繁的干扰纳入一个管理的景观，如美国南部的森林海岸平原，必须平衡的愿望与可能的。我们提出了一个适应性战略，区分事件风险（飓风发生）沿海森林的脆弱性和结果风险（飓风的严重程度）。我们的策略侧重于管理干扰事件，干扰后的系统，以及恢复过程，然后修改初始条件，以减少脆弱性。我们将这些概念应用到最近的卡特里娜飓风和丽塔对墨西哥湾北方沿海平原森林的影响的案例研究。
The Indian Ocean Tsunami focused world attention on societal responses to environmental hazards and the potential of natural systems to moderate disturbance effects. Coastal areas are critical to the welfare of up to 50% of the world's population. Coastal systems in the southern United States are adapted to specific disturbance regimes of tropical cyclones (hurricanes) and fire. In August and September 2005, Hurricanes Katrina and Rita caused what has been termed the most costly natural disaster in U.S. history, including an estimated $2 billion to $3 billion in damage from wind alone. A total of 2.23millionha of timberland in the coastal states of Texas, Louisiana, Mississippi, and Alabama was damaged. Although financial loss estimates are incomplete, there is little doubt that these hurricanes caused extensive damage and their effects on the landscape will linger for years to come. Crafting a strategy for incorporating large, infrequent disturbances into a managed landscape such as the forested coastal plain of the southern U.S. must balance the desirable with the possible. We advance an adaptive strategy that distinguishes event risk (hurricane occurrence) from vulnerability of coastal forests and outcome risk (hurricane severity). Our strategy focuses on managing the disturbance event, the system after disturbance, and the recovery process, followed by modifying initial conditions to reduce vulnerability. We apply these concepts to a case study of the effects of recent Hurricanes Katrina and Rita on forests of the coastal plain of the northern Gulf of Mexico.
