9407709 Keeley Over a period of less than ten days in the autumn of 1993, the southern California landscape exploded in massive wildfires that burned more than 200,000 acres. This ecological event, with 15 fires ignited at the same time, presents an unparralleled opportunity for answering several important questions about the regeneration of chaparral and coastal sage scrub vegetation. Two unique opportunities are presented by this event: (1) postfire successional events can be investigated in different communities and different climatic regions under similar initial conditions, and (2) countless replicates are available which will allow for sites to be selected that are similar in most site characteristics, except for fire intensity, pre-fire history, and post-fire recovery management efforts. In this study, the PI will establish a large set of permanent plots in different replicated communities to address questions that have eluded fire ecologists to date. %%% This study represents a unique opportunity to study natural regeneration processes in southern California chaparral and coastal sage scrub vegetation. This research will provide a sound scientific basis for ecosystem management as applied to the heavily populated southern California region. Also, emergency management plans have been proposed, many of which are based on emotion and limited data. This research will yield broadly applicable management information which will help to mitigate the impacts of this type of catastrophe in the future. ***

9407709 Keeley 1993年秋天，在不到10天的时间里，加州南部发生了大规模的野火，烧毁了20多万英亩的土地。这一生态事件，与15个火灾点燃在同一时间，提出了一个无与伦比的机会，回答几个重要的问题，再生的查帕拉尔和沿海鼠尾草灌丛植被。这次活动提供了两个独特的机会：（1）可以在类似的初始条件下，在不同的社区和不同的气候区域调查火灾后的演替事件，（2）无数的复制品，这将允许选择的网站是在大多数网站的特性相似，除了火灾强度，火灾前的历史，火灾后恢复管理工作。在这项研究中，PI将在不同的复制社区建立一个大型的永久性地块，以解决迄今为止一直困扰火灾生态学家的问题。 %这项研究是一个独特的机会，研究自然再生过程在南部加州查帕拉尔和沿海鼠尾草灌丛植被。这项研究将为人口稠密的南加州地区的生态系统管理提供可靠的科学依据。此外，已经提出了应急管理计划，其中许多是基于情感和有限的数据。这项研究将产生广泛适用的管理信息，这将有助于减轻这种类型的灾难在未来的影响。 ***
