註釋

Althouugh biodiversity assessment has become a topic of interest in the last decade, there are no specific guidelines as to how such assessments should be conducted, and the initiation of such projects can be a daunting task. The primary goal of most biodiversity assessments is to obtain species lists for the taxa of interest; but species lists are only a first step. Biodiversity assessments provide opportunities for monitoring community changes over time, prioritizing areas of conservation concern, and developing testable hypotheses relating patterns of geographic variation in species assemblages to selected environmental factors. If the data collected are to be useful for elucidating ecological relationships or monitoring trends over time, rigorous methods of sampling and analysis must be established to aid managers, systematists, and ecologists in obtaining useful biodiversity data, we have described an integrated approach to biodiversity assessment. Our approach includes the use of species effort curves, Geographic Information Systems, remotely sensed data, and multivariate ordination techniques. We address selection of taxonomic groups, sampling replication, and the relative merits of presence/absence data and abundance data for terrestrial systems.
