i think if properly designed, giraffes have a place at taronga. cherryenne mountain zoo built a fantstic giraffe mixed exhibit in the side of a hill stepper than taronga. it is a great exhibit, this is what taronga should do.
it has inside viewing at eye level, and a huge boababb tree, with hog veiwing and small rodents. on the hill there is a 3 story colubus exhibit, and it is really kool. research it ppl, great place.
i also think, though controversially, taronga has a place for rhinos, kwannza (?) looked happy there when i was there, and it the exhibit was done properly every 6 months a dubbo rhino could go there, it would assisit dubbo as there are to many males.
my plan i took to taronga was to take the old ele exhibit and turn it into an extension of tropical rainforest, if it was poosible to move the urlers gibbon, i would put pygmy hippo under tht nice fig, maybe with some primates, and bongo and okapi (

in the old ele exhibit. (i know see the ele exhibit has greater place as tht, an ele exhibit)
leaving a place for rhino, giraffe, zebs, eland maybe, ostrich, small brids, etc at a new african waterhole.
i would then make a asian higlands, linking to the current asia, take the snow leopard exhbit as a start, connecting to red pandas thar. the 2 tiger canyons for breeidng tigers- move lions to waterwhole- sun bears in bear canyon, dholes as well in the asian forest section.
meerkats to savannah as well (also at tht zoo i was talking about). then south america can have the tapir (who is living in the african waterwhole lol), and the peccaries, maybe a manned wolf or 2, and this can all go down bottom of ele exhibit instead of the proposed new guinea.
does anyone have a plan to the masterplan- a map or there alike
