Currently, Bhutan is home to 11,248 known species from the following kingdoms: Animalia, Plantae, Chromista, Eubacteria, Fungi, and Protista. The two largest known kingdoms are Plantae and Animalia, which together account for 93% of all species. The smallest kingdom is Protista, which accounts for only two species (less than 1% of all species). However, the kingdoms Chromista, Eubacteria, and Protista are severely underexplored and much research is required in order to gain a better understanding of the number and diversity of species within these groups. Currently, there is no record of even a single species in the kingdom Archaebacteria.
