Most people understand that the poaching of rhinos is cruel and could, quite possibly, drive rhinos to extinction. But why the inordinate fuss about rhinos? Are they special enough from an ecological point of view, that ecosystems need them to be around? Of course, no species should go extinct due to man, and rhinos are iconic symbols and tourism draw-cards. But aside from those sound enough reasons, do rhinos earn the right to stay from an ecological point of view? Rhinos are what we call a ‘keystone species’ – one whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system. That is why we should fight to keep rhinos alive in our wild ecosystems. The rhino has several essential roles that few people are aware of, and this article hopes to highlight those lesser-known environmental and biological services that they provide.
