Floristic and faunal Cape biochoria: do they exist?

The Cape Floral Region (CFR) and its extended counterpart, the Greater Cape Floristic Region (GCFR), exhibit remarkable biotic distinctiveness, characterized by unparalleled species richness and endemism. This study challenges traditional perceptions of biochoria—biogeographical patterns of species distribution—by assessing whether such patterns exist in both floristic and faunal components of this region. Utilizing a comprehensive review of historical and contemporary literature, the research synthesizes data on climatic conditions, phytogeography, and faunal distributions to evaluate the coherence of these biogeographical units. Findings suggest that while the CFR stands out as a unique floral kingdom, its integration with the succulent Karoo region into the GCFR provides a more coherent biogeographical framework. The study underscores the need for recognizing both the distinctiveness and interconnectedness of the Cape's biodiversity, offering insights critical for conservation efforts in UNESCO World Heritage Sites.
