The Jarrah-Karri Forest and Shrublands occupy the southwestern corner of Western Australia, roughly between Cape Naturaliste and Albany, forming an isolated wet-forest refuge within the country's Mediterranean-climate Southwest. The signature tree is karri (Eucalyptus diversicolor), among the tallest trees in Australia, joined by three tingle species and giving way to jarrah (Eucalyptus marginata) and marri on poorer, lower-nutrient soils. The climate is Mediterranean, with hot dry summers and cool wet winters, and this is the wettest zone of the Southwest biodiversity hotspot. It is exceptionally rich and highly endemic, harboring the Albany pitcher plant and endemic frogs such as the orange-bellied, white-bellied, and sunset frogs, while logging, wildfire, feral predators, and Phytophthora dieback remain the main threats. For gardeners, the red-flowering gum (Corymbia ficifolia) is a widely grown ornamental native to this region.

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.
Climate-resilient picks · 52
These plants fit this ecoregion today AND remain in range under the mid-century SSP3-7.0 projection. Lead with these for a planting that holds up as the climate shifts.
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.
