In recent years, rapid biological and social asset inventories have proven more and more useful to conservationists. Their goal is to quickly catalyze effective action in threatened regions of high biological diversity and uniqueness. The scientific teams focus primarily on groups of organisms that indicate habitat type and condition and that can be surveyed quickly and accurately. The teams produce efficient, integrated approaches to identifying the important biological communities in the region and determining whether those communities are of outstanding quality and significance in a larger context. These volumes represent the results of these inventories – rapid assessments of threatened areas about which comparatively little is presently known. These data – including ecological profiles, technical reports, and summaries of potential threats and conservation opportunities – are not only the best biological snapshot we can take of these regions but also the necessary blueprint for any steps taken to conserve and protect them.
