A Glimpse into the Southwest’s Biodiversity:

The Southwest Australian Floristic Region is a biodiversity hotspot, home to over 10,000 plant species, with over 90% endemic to the area. This extraordinary diversity is attributed to several factors, including:

Ancient Landscapes: The region’s geology, shaped by ancient tectonic plates and subsequent weathering, has created a mosaic of soil types, ranging from nutrient-poor sands to rich clay loams. This geological diversity has led to the evolution of specialized plant species adapted to specific soil conditions.
Climate Variability: Perth experiences a Mediterranean climate with hot, dry summers and cool, wet winters. This distinct climate pattern has driven the evolution of plants with drought-resistant adaptations, such as deep root systems and waxy leaves that reduce water loss.
Isolation: The region’s geographic isolation has prevented the influx of new species, allowing endemic plants to evolve and diversify over millions of years.
