Justification of Ecoregion Delineation

The Southwest Australia Savannas ecoregion comprises three IBRA’s: ‘Geraldton Sandplains’, ‘Avon Wheatbelt’, and ‘Yalgoo’ (Thackway and Cresswell 1995). Vegetation includes savanna woodland, mallee scrub, and heath. This region is a transitional zone between mediterranean climates and the central arid regions. A portion falls within the ‘South-west Botanical Province’ Centre of Plant Diversity (Beard 1995), and the southern portion of this ecoregion falls within the ‘South-west Australia’ Endemic Bird Area (Stattersfield et al. 1998).
