The two Asian forest rhinos were widespread and abundant until recently, but it is no longer possible to study their ecological roles since they have been eliminated from 99.99% of their former ranges. The exception is the Javan rhino population in Ujung Kulon, which is presumably at near-natural density in a fairly diverse lowland tropical forest. There is frustratingly little in the English-language literature on its ecological impact, by seed dispersal or browsing (although the latter is conspicuous when you visit). Am I missing either papers in Indonesian journals, in English or Bahasa, or grey-literature publications that the search engines miss? A list of seeds in dung would be interesting.
