Chilean vegetation in the context of the Braun-Blanquet approach and a comparison with EcoVeg formations

Aims : The Braun-Blanquet approach has been widely implemented to generate classification schemes at the country level and Chile is not an exception. In spite of numerous studies, a revised system for whole still missing most current surveys are restricted small set vegetation groups or specific study sites. To fill this gap, we established vegetation-plot database updated into single syntaxonomic scheme. We also performed comparison scheme with formation following EcoVeg approach. Study area Continental Chile. Methods compiled 1,582 plot observations, which classified 29 classes, 43 orders, 65 alliances, 162 associations according Results These observations were assigned 7 10 subclasses 19 formations in There several mismatches between phytosociological classes formations, indicates some inconsistencies stage syntaxonomy Besides big contrast on bioclimatic conditions within country’s territory, occurrence intrazonal may explain high diversity recorded database. Conclusions This work constitute basis implementation levels alliance association can be extended other countries South American sub-continent.
