Yeah, that's bothered me a bit. Personally, if I was in charge there, I would:
- Remove the Camels & Llama from EAGR. Replace them with the Scimitar-Horned Oryc from BGP and Nyala. Move pygmy goats to Pets Corner or Animal Adventure then adapt the exhibit for cheetahs.
- Expand the current tapir enclosure to take up half the grassy land behind the EAGR, also mixing rhea, capybara and anteater with the tapirs. Use the second half as a paddock for spectacled bears, creating a South American area.
- Mix Elephant & Okapi with the bongo, creating a Congo forest.
- Move out the Camels & Pere David's deer from BGP, withe the Oryx going to the EAGR. Replace with the Eland, Wildebeest, Kudu & Bontebok.
- Move out the Red & Fallow Deer into a new deer park just outside Longleat House, creating a more scenic setting. Move the Camels & Pere David's deer from BGP here, along with Bison & Prezwalski's Horse, creating a Eurasian Reserve.
- Mix the Flamingoes, Ibis, Spoonbills and Ducks with the pelicans, in order to give the elephants a pool. Add marabou stork to create an even larger African Wetlands aviary.
As you can see, this would give Longleat a much more educational value. However, it is of course a visitor vision, so it would be very unlikely, but still provides a better insight.
