Very good news
Camera Traps Capture 35 Rhino In Indonesian Park - From the Wires - Salon.com
Oh my that sure is good news - cheers for the Heads Up Hix xx
Interesting how these "press release" figures don't correspond with figures talked of by the people who analyze these photos.
Happy New Year btw
My guess would be that the higher numbers (40-60) are an extrapolation from the number actually photographed based on some kind of ecological model of how the rhinos use their habitat and the assumption that the camera survey likely did not capture all of the rhinos out there.
Without going into too much detail (for fear of saying something I shouldn’t) the number photographed isn’t even accurate. Camera traps cover the entire park and the survey has been ongoing for a number of years to the point where individuals are recognized. In this, admittedly rare, case a precise number is known and it’s not acknowledged in that article.
Wouldnt the fact that there nearly twice as many males as there are females be a concern?
In another thread (Rhinos) you state there are 'probably no more than 27 individuals left and some of those may be post-reproductive'.
Presumably that is a closer/more accurate assessment of the real population?. But where did the sex ratio breakdown of 22;13 animals quoted here come from?
