The research network will carry out continental scale biogeographic analyses relevant to setting international research and conservation priorities for neotropical dry forest. These biogeographic analyses would be the first based upon robust floristic data from across the full geographical extent of neotropical dry forest. To make the task feasible, we will focus on the woody plants (defined as reaching 3m in height and not including lianas or climbers) that structurally dominate neotropical dry forest, of which there are an estimated 4000 species.The DRYLOR Network has placed all floristic data for woody plants of neotropical dry forest in a single searchable database. These data derive from quantitative ecological inventory plots and more general floristic lists for specific areas. A key methodological issue is the cleaning of data and especially the resolution of taxonomic ambiguities (i.e., synonyms - different scientific names used for the same species in different surveys) to enable all data from different countries to be compatible.
