When Hurricane Andrew slammed into Everglades National Park with wind gust over 170 mph, it deciminated the local forest while leaving areas of open wetlands largely unharmed. Trees were stripped of al their leaves, most branches were broken off, and m any trees were toppled or shattered. Only a few trees remained standing in some mangrove forests. Evergreen woodlands were transformed from lush forest to brown tangles of leafless debris. Bald cypress and slash pine forest were also heavily damaged. Although Andrew was a natural disaster of enormous scale, hurricanes in the region have been frequent in the past and must have been an important force shaping these forests. As the first major hurricane to directly strike the Park in over 25 years, Hurricane Andrew presents a rare opportunity to investigate the speed and patterns of forest recovery. This information is important because forests make up critical fish and wildlife habitats and recreational areas with the Everglades, even though the Everglades are commonly thought of as open wetlands. Both the degree of damage and the speed with which trees can regrow will determine which species make up a post-hurricane forest. The native tree species within the Park appear to differ greatly in their abilities both to withstand hurricane-force winds and to regrow after hurricane damage. The recovering forest should be composed of those tree species that were damaged the least, those that can resprout the fastest, as well as those that can invade open areas. Research will focus on the extent of damage to the trees species within mangrove, tropical hardwood, pine, and cypress forests in Everglades National Park. Data will also be taken on which species recover from damage, how fast they recover, and which species colonize open areas in the forests left by the hurricane. This information will help to predict what the recovered forests should look like as well as understand how hurricanes have affected these forests in the past.

安德鲁飓风袭击大沼泽地国家公园时 风速超过每小时170英里，摧毁了当地的森林 而开放的湿地基本上没有受到伤害。 树木 所有的叶子都被剥光了，大部分的树枝都被折断了， 任何树木都被推倒或粉碎。 只有几棵树 仍然矗立在一些红树林中。 万年青林地 从郁郁葱葱的森林变成了一片光秃秃的 碎片 秃杉和湿地松林也受到严重影响。 损坏 虽然安德鲁是一个巨大的自然灾害 过去，该地区的飓风频繁发生， 一定是塑造这些森林的重要力量 作为 25年来第一个直接袭击公园的大型飓风 多年来，飓风安德鲁提供了一个难得的机会， 调查森林恢复的速度和模式。 这 信息很重要，因为森林是重要的鱼类来源， 野生动物栖息地和娱乐区， 尽管大沼泽地通常被认为是开放的 湿地 无论是破坏的程度还是树木 再生将决定哪些物种构成飓风后的物种 森林 公园内的原生树种似乎有所不同 它们在抵御飓风的能力上有很大的提高 风和飓风破坏后重新生长。 回收 森林应该由那些被破坏的树种组成 最少的，那些可以最快地恢复的，以及那些 可以侵入开阔地带 研究将侧重于 对红树林、热带硬木、 大沼泽地国家公园的松树和柏树林。 数据将 还需要了解哪些物种从损害中恢复过来，恢复速度有多快 恢复，以及哪些物种在森林中的开阔地带定居 飓风留下的。 这些信息将有助于预测 恢复的森林应该是什么样子， 飓风过去是如何影响这些森林的
