Judging from the artist impressions, there are a number of outdoor enclosures leading from from the main structure. Some appear to be moated, so I assume these are indeed enclosures...
As one who is familiar with all four Okapi enclosures in the UK..
IMO;Chester's is the most naturalistic and the outdoor areas are a reasonable size(though not massive)
Bristol's outdoor enclosures are simple small grassy paddocks, attractive exhibit but small.
London's is a converted corner paddock of the Cotton Terraces and they have planted some trees to give a better feel to it.
Marwell's has one large and one smaller paddock. Its the only place I have seen an Okapi running and is probably the only paddock of the four which is really big enough for that. But its just grass plus a couple of oak trees. Some of their Okapi nowadays also use the adjacent former Bongo house and paddock.
Chester's (and to a lesser extent London's) score on the 'natural' feel, Marwell's is the most spacious.
I don't think it is too small, okapi are normally solitary and I think there is enough room. It's not like they spend all day galloping around the enclosure.
No, I definately don't think its too small either. The two paddocks are a lot longer than they look in this photo which shows only the middle and furthest ground.
Okapi do like to exercise by cantering around sometimes, but even in a moderate size enclosure they can do that by developing a figure of eight pattern around the enclosure. Thy don't do it a great deal but its very graceful to watch (I've only seen this at Marwell)
No, I definately don't think its too small either. The two paddocks are a lot longer than they look in this photo which shows only the middle and furthest ground.
I like the enclosure very much and is mush better than the others I have seen although I would like to see more room given to them, esp if they want to breed them.
