The world’s largest biodiversity data aggregators use TDWG data standards to integrate data from more than 1,300 data providers. Our standards are developed and maintained by practicing biodiversity scientists and data managers from around the world. The social infrastructure that TDWG provides enables this international collaboration. TDWG itself depends on its members to operate and maintain its collaboration tools and do the actual work of standards development. The financial support of its members makes TDWG more effective. Please join! TDWG has individual and institutional memberships.
