Yes, the elephant enclosure now covers the area previously used for both the elephants and the giraffes. I believe the new giraffe enclosure is next to the lions, although I haven't visited the zoo for a number of years.
Way back in the 1970s/early 1980s, they had a pair of White Rhino sharing this space as well !
The zoo used to rotate access to the paddock for the giraffes and the rhinos.
Seeing your photo brought it all flooding back!
And the area now doesn't look big enough for the elephants alone!
