Is this the whole exhibit? I really don't like seeing concrete climbing structures for animals (it's forgivable when there are live trees and ropes interspersed). If you imagine these trees as bare cement than people would be outraged.
what's interesting with this photo is how the fake baobabs make the island seem really small, and if there weren't some lemurs in there for scale (in the shadow of the left-hand tree) you wouldn't know what to think.
In terms of appearance I think the baobabs look hideous and completely out of proportion, but at least the lemurs can use them for climbing around on top of (there's a rope going from one of the real dead trees to a branch on the right-hand baobab, and it looks like they can get onto the left one as well).
I agree that the baobab trees are hideously-designed, but the ring-tailed lemurs do have access to all 3 of the fake trees on the tiny island. One could make the case that these lemurs are better off than the red ruffed, common brown, collared brown and mongoose lemurs that are indoors within glass-fronted exhibits.
It is my understanding the of all the lemurs the ring tails are the most terrestrial and spend most of the day foraging on the ground, it would be a better show if the island was grassed a with a couple of live shrubs at least. Though it looks as if the whole thing could be /is solid concrete.
