Replacing common species with rarer ones in zoos

[Evo]

Some zoos often display species that are either extremely common in zoos or ones that serve no conservational value, whether they are least concern or a generic population *cough* most lions and "Bengal" tigers *cough*. This thread is for people to comment what they would do to the species collection and whether they will replace species, move them into a new enclosure or mix them, at a specific zoo.

Guidelines:
1) Please be realistic, so no northern white rhino, south china tiger (possibly) or mountain gorilla (possibly).
2) Have fun.

First, I will start with West Midlands Safari Park in the UK.
1) Castrate the males of the lechwe, eland and waterbuck.
2) Give the male zoomix lions and the male white tigers a vasectomy.
3) start to go out of zoomix lions (easier said than done).
4) Import some tan Panthera leo krugeri and mix with the white lions.
5) Move the Krugeri pride to the main lion paddock once the zoomix lions have left.

These are the changes I can think of at the moment.

This is an interesting topic, and I had a few ideas brainstorming in my head

Detroit Zoo/Lincoln Park Zoo (and any zoo that has Reticulated (G. reticulata) X Rothschild (Giraffa camelopardalis rothschildi) hybrids)
1. Sterilize or split apart giraffes to prevent any breeding.
2. Somehow phase out the zoomix giraffes.
3. Encourage breeding the Masai giraffes to collections that carry them (Giraffa camelopardalis tippelskirchi).
4. If possible (I highly doubt it, since giraffes are pretty hard to transport and moving them overseas would be downright risky), import other pure species/subspecies of giraffes (either from European, African or Asian collections) to the Americas. If not, then have a few zoos display surplus Masai giraffes.
