Dr Nicolaas Jan van Strien, Chair of the IUCN/SSC Asian Rhinos Specialist Group from the Netherlands peacefully passed away at home after his struggle against an aggressive cancer that struck him ten months ago. We are very sad that he is no longer with us, but we will cherish the many good memories of him as a loving, caring and inspiring person.

Nico, as he was known to colleagues, was, without a doubt, the world’s authority on both Sumatran and Javan rhinos, having studied and authored numerous scientific papers on both species. He dedicated more than 30 years of his life to rhinos.
