Interim Biogeographic Regionalisation for Australia

L'Interim Biogeographic Regionalisation for Australia, ou IBRA, est un plan de découpage du continent australien en régions biogéographiques créé par le « Ministère de l'environnement et de l'eau » australien pour servir de base de travail par exemple pour la création de réserves naturelles.

En 2007, ce plan en est à sa version 6.1, ce qui donne le découpage suivant de l'Australie (le code des régions figure entre parenthèses). On peut consulter le plan sur le site de l'IBRA. :
