Application of IUCN criteria and Red List categories to species of five Anacardiaceae genera in Madagascar

摘要: The conservation status of five genera Anacardiaceae in Madagascarwas determined by applying IUCN risk assessment criteria to recent taxonomicrevisions and available specimen data. A major problem establishing protocolsfor efficiently protecting conserving Madagascar's biodiversity is the lackof essential biological information. In light this, primary occurrence dataappears be an invaluable tool for assessing both current historic speciesdistributions. GIS technology was used create species distribution maps forhistoric vs. data analyze change conservationstatus, extent occurrence, area occupancy each targetspecies. GAP analysis reveals that 14 (100%) target whichdata were are considered threatened standards. Furthermore, 11(79%) showed a decrease number subpopulations theirextent when compared distributions. This studyhighlights importance two factors necessary address modernconservation questions. Sound conclusions regarding ofindividual requires strong taxonomic framework good collectiondata distribution. However, because very oftenincomplete biased geographically taxonomically, reaching soundconclusions field knowledge individual compensate forthese limitations.
