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.

Individual membership can be paid online with a credit or debit card.
Institutions, as well as individuals who need to pay through a formal quote/purchase order/invoice process, should request an invoice by sending an email with name, affiliation, address, and desired membership type individual/institutional to the TDWG Treasurer.
Invoices for membership dues can be paid:

Institutional member votes are weighted by five ( × 5 ) in situations where votes of institutional and individual members must be combined, such as the election of officers. ↩
Institutional memberships paid in the first quarter (before 31 March) are usually discounted 20% (reduced to $400). ↩
