The dehorning experiment was a total failure. The premise was that,
without a valuable horn, the poachers would leave the Rhinos alone.
In reality there were two main problems with this. Firstly, after
spending a week or two stalking a Rhino only to discover that it
was dehorned the average poacher would not go "Ah, well, nothing
of value here, let's leave it alone", instead their reaction was more
like "We've wasted two weeks tracking this one, lets kill it so we
don't waste time tracking that one again". Secondly, not all the
horn was removed (the horn base was retained), so there was still
some valuable keratin left. Rhino horn is so valuable that even that
small amount was worth a lot to the poachers.
To make matter worse, unless you get a good close look at the Rhino
in profile it is difficult to tell that they are dehorned - so, the fatal
bullet could easily have been despatched before the poacher knew
whether or not the Rhino was dehorned. A hornless Rhino does
look pretty weird though.
An adult Rhino would be able to defend it's young pretty well
without a horn - the juveniles aren't born with the horn so
they can't use it as defence until they are reasonably big anyway.
A kevlar horn would be indistinguishable from the real thing to
the eyes of a poacher - who would shoot the animal anyway.
I would have to say that the predation in question was mostly
human. Once the parents have been killed most juveniles
have poor survival chances, horn or not.
