• This report is divided into seven chapters. The first chapter (Approach) provides an overview of the methodologies used in this study. A more detailed description of the methods can be found in Appendixes A and B. The second chapter provides a description of the METs and MHTs found in LAC, their geographic locations, and the ecoregions they contain. See more detailed definition of MHTs in Appendix C and the hierarchical classification scheme of ecoregions in Appendix D. Brief descriptions of the ecoregions and key sources consulted for their delineation, classification and assessment are in Appendix F. The third chapter presents the results of the analysis of conservation status by MHT and across MHTs. The raw data for each ecoregion used to compute conservation status are in Appendix E and detailed information on sources consulted for remaining natural habitat and protected areas is in Appendix G. The fourth chapter presents an assessment of the biological distinctiveness of ecoregions within their MHTs. The fifth chapter explains how to use the methodology as a tool in conservation planning. The sixth chapter addresses the conservation status of mangroves of LAC which we assessed using an approach adapted from that developed for the terrestrial ecoregions. The last chapter provides our conclusions and recommendations. After summarizing the results of the study, we discuss the possibility of using our approach at an ecoregional or intra-ecoregional scale. Such analyses at finer geographic scales are an essential follow-up to this study. Without them, donors run the risk of financing biodiversity conservation in the most important ecoregions within a major habitat type, but conserving some of the less important habitat blocks within those ecoregions, or at an insufficient level to conserve their biodiversity. We offer some guidelines that highlight maintaining landscape integrity and better conserving areas characterized by high rates of species turnover (beta diversity), and we give prominence to unique habitats.
