The Eyre and Yorke Mallee ecoregion occupies the Eyre and Yorke peninsulas of coastal South Australia, a disjunct outpost of the Mediterranean-climate woodlands of southern Australia with temperate, wet-winter conditions. Its characteristic native vegetation is low woodland and mallee dominated by dryland tea tree (Melaleuca lanceolata) and mallee box (Eucalyptus porosa), alongside genera such as Callitris, Acacia, and Geijera. Roughly half of the flora is considered of conservation significance, and the Eyre Peninsula alone holds numerous endemic plant species. Much of the original vegetation has been cleared for farmland, leaving scattered remnants conserved within protected areas such as Innes and Coffin Bay national parks. For gardeners in comparable dry-summer climates, the region is the native home of several hardy ornamental and shade trees, including sugar gum (Eucalyptus cladocalyx), river red gum (E. camaldulensis), and the southern native pine (Callitris preissii).

About the mediterranean forests, woodlands & scrub biome

Regions of hot, dry summers and mild, wet winters supporting drought-adapted shrublands — chaparral, maquis, fynbos — and open woodlands. Fire is a natural shaping force, and these climates hold extraordinary plant diversity and endemism.

Catalog plants suited to this ecoregion

Computed from each plant's stated USDA zone range against this ecoregion's CHELSA-derived current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.

Collections for this ecoregion

No curated collection's plants all fit this ecoregion's zone range. We surface a collection only when every member would grow here — partial fits get filtered out rather than mislead. As the catalog and the curated set both grow, this section will fill in.
