Although its orange sun is only about 90% the mass of Sol and half as luminous, Rannoch is arid by Earth standards because it formed closer to its star and has slightly less ocean coverage. Photosynthetic life is concentrated around rivers and oceans, with large expanses of desert in between. The importance of plant life and shade in ancient quarian culture is evident in the translation of Rannoch's name -- "walled garden."
Rannoch has no insect life. As a result, its pollinating plants evolved to rely on animals for propagation. This symbiosis between flora and fauna is responsible for the quarians' weakened immune systems, which made colonization of other planets extremely difficult after their exile from Rannoch. For many quarians, reclaiming their homeworld from the geth and forming a new alliance with them was both a cultural and physiological victory.
To a starship's sensors, the most obvious feature of the quarian homeworld is the numerous heat sources in orbit. Thousands of geth space stations watch over the planet. Since the alliance between geth and quarian, most of the stations have been re-purposed for quarian military use.
