That's the plan for now, and will likely stay like this unless frontier releases a new african primate or bird, which let's be honest isn't happening.
Well, it looks like I bite my own tongue after all.
Well, i gotta say, since i posted this i made some changes on my plans regarding the Dier zoo, and now that the dlc is here i decided to change even more things
So to let everything organized for myself i decided to post here everything that i changed and my overall plans for the zoo, beginning with the pre-announcements plans:
-Instead of making the RRH and water Buffalo (stand in for red buffalos) habitats a back-to-back complex, the RRH now resides right by the side of the outpost, so guests inside of the outpost can see the hogs. While the buffalo habitat has been increased in order to accomodate the buffalos and to also being able to have nyalas, something that despite being present on the original paper I wasn't so sure if they would make the cut. The barn of the habitat also changed place, so instead of being in the visitor patch and right next to the reptile house, it will now be on the other side, far from the guests.
-speaking on the outpost, my original plan for it was making it a part without animals, only with fossils and other educational props, but i decided to change it and include the monarchs (implied to be wild animals) on the entrance garden and the snail + goliath beetle on the adjacent restaurant, not to mention the hogs.
-The rest of the tropicalia zone plans were also changed to make the overall design of the area more compatible with the "modern zoo" view, but nothing particularly worthy to mention.
-The great plains zone will also change plans when i come to that point. The overall design and layout will change in order to make the whole are seen more natural, for example, in the old plan, the rhino, wildebeest and zebras would be in a habitat, with a patch and a educational center separating than for the rest of the zoo, in the new plan, it will looks like they share a very big space with the giraffes + cape buffalos, cheetahs and to a certain stand, the lechwes and hippos, despite the existence of barriers between then. Some other minor changes include the ostriches living with the warthogs now and the addition of sable antelopes to the zoo, after i got a 100% male from a challenge, living in the same habitat as the springboks.
-The desert outpost will also change plans, as the overall layout will become a proper loop starting in the market and the desert house and finishing in the place, alongside the additions of some of the zookeeper pack animals.
Now to the dlc/update animal related changes, and going by each animals, we got:
African leopard: i originally didn't have any plan with this guy, despite it being a core specie in the Dier zoo lore, however i decided to change plans and giving them a habitat right above the buffalo/nyala one, giving again the illusion they are in the same habitat, while making the leopard standing in the center of the area, giving the idea of it relevance to the tropical forest.
Sifaka: while the Madagascar area is complete, it has been some time that i've been wanting to remake the ringtail lemur habitat, and now that the sifaka is coming, I decided to remake the habitat to also include this guy.
Spurred tortoise: those guys will make a new room in the desert house, right next to the sand cat, also ngl, but their inclusion will make the house far more diverse, as all the habitats prior to this point would have a carnivore.
Baboon: if you look at the original map, you would realize that the area between the caracal and endangered ungulates house was empty, and so, i decided to include the baboon habitat right there, despite still not having any concrete idea for the habitat.
Dik-dik: i don't have many ideas for this guy, i will probably either throw them in a random already planned habitat or make a small, aviary-like habitat for them, not sure yet.
So, I think I will turn the left space into a dikdik habitat and the sifaka and the tortoise aren’t allowed to go to the zoo, sorry. But this whole zoo was originally planed for highlands animals. Since I already have in mind, what animals should come to the Africa, Australia, South America, northamerica and Europe area, I don’t know, which animals I should build into the Asia area (besides snow leopard, Malayan Tapir (I know, not an Highlands species, but whatever), Pallas cat and Markhor)
