According to this article 7 rhinos were born in 2015, which is fantastic news and a great boost to the population. https://www.savetherhino.org/latest_news/news/1466_positive_news_for_asian_rhinos Not much detail though, anyone have any more news on the births? how they were recorded?
Great news ! I know in the early years of the programm searching for footprints was very inportant in indentifying the single animals, now-a-days I guess also camera-traps play an important role.
I think perhaps a combination of both nowadays? With camera traps particularly, they can identify the individual females/mothers so know they are not over-counting the number of young. I see there are calls/suggestions for the female Sumatran rhino captured recently in Kalimantan, to be transferred to Way Kambas in Sumatra.
