Thanks for the prompt response. It makes me realise how few ungulate species I've seen. I think I've already seen more new antelope species in the 4 zoos I've visited in the UK than I had seen up until coming here.
Many of those trees are young yet. There is a new grove of African fever trees, and when it grows in it will be nice and forest-like. Unfortunately because of the elevation of the tram pathway, this will mean it will be a difficult exhibit to see anything in.
