I can't read this either, but from other comments it seems they decided this old enclosure is 'unsuitable' for them and have sent the last two Giraffe(females) to Blair Drummond Safari Park which is in Scotland,and where they will have much more room. Some people on here have commented they are losing too many big species this way, having just lost Sealions also. It might have been better to renovate/rehouse them within the Zoo but cost seems a significant factor here.
Elephants- unlikely they will leave- the Housing is modern and they are a big draw.
