The Zoo has finally released their new vision for the future. I will say that I am kinda more excited for this version than the previous version. The Zoo and the Zoological society are merging their resources into one and addressing many of the needs that the zoo has in this new plan. Though there's a lot of positives, I do have some questions about other areas.
Projects
Latin America: I would more dub this as the Belize Land. This is where there the rainforest exhibit is going, along with the salt water aquarium with sharks.
Primates of the World: Finally renovating the current facility to be better inline with current standards and getting rid of the box cages!
The Wild North: The former Alaskan Gold Coast, wolves, and the moose is coming out from back stage.
Sea Lion Cove: Combining the former pinnipeds exhibit that was recently shut down with the current one, to form a better experience for guests and animals.
Reptile House: The facility is going to become primary reptiles and amphibians.
Cheetah House: Finally bringing the former goat exhibit by the elephants to life again.
Entrance Renovation: Moving paying for entry and parking to the front of the zoo and not at the toll booths.
Consolidated Administration: Zoological Society and the Zoo sharing the same building/space.
Warehouse: New space for climate controlled storage to support the zoo.
Southeast service road: Creating a service road access from the south to the west side of the zoo.
Railroad Refresh: New tracks
New Carousal: New one
Questions:
My biggest question is what's going to happen with the building and exhibits around the current big cat building? This was similar to the old master plan but with them creating new space for the jaguar, tapirs, cheetahs to name a few, what's going in that area.
What's up with the guest flow around the former polar bear exhibit in this new plan? They are disconnecting it from the elephant loop.
What's the timeframe of this new plan? All the material that I was able to go through doesn't give a real time estimate on these projects.
Updated Master Plan
I've been thinking about this Master Plan lately, particularly about what animals could be moving in, out, or shuffled around the Zoo. So, why not throw in some fantasy ideas since some of this isn't a sure-fire thing?

I'll try sticking to what the documents presented us to be more realistic, mainly the first three projects because that's what the Zoo is heavily focusing on right now.
Latin American Tropics - Swap out the howler monkeys for the current spider monkeys to both give them a new home, and tie them in with the Belize theme. There's potential for some of the smaller species from the
Small Mammals Building to be rehoused here, like the armadillo, prehensile-tailed porcupine, sloth, and more, so I'd find a way to incorporate them. Lastly I'd like to see a larger jaguar habitat (hopefully with the underwater viewing that's in the concept art) and the addition of bush dogs - yes they don't exactly fit the theme, but neither do the proposed capybaras!
Primates of the World - Keep the gorilla and bonobo plans as they are, except I'd find a way to mix in the colobus with the former to create a more dynamic setting. We don't know much about the other half of the building except for the "medium primate," so the rest will be more fantasy. To utilize those cables I'm hypothesizing, I don't see why the Zoo can't keep orangutans and even mix them with siamangs, so I'd use them for the intended "medium primate" exhibit. Next, a portion of the building could be dedicated to tamarins (I'm flexible with the species) in a mini-walkthrough jungle, along with some other small animals possibly. Then, new and improved exhibits for monkeys; the de Brazza's can stay, and I'd like to see a new species or two if space allows - perhaps douc langurs if that Nashville deal takes off? Finally, as an added bonus, the former sea lion show arena can be overhauled for a Madagascar section, with new and improved lemur habitats, and the addition of fossa, aye-ayes, and hopefully others.
Wild North - I like the idea of moving from temperate forests to the taiga, so I'd keep that concept, the habitats, and species line-up. The only real change I'd make is if polar bears return, it would be nice to have a larger pool and, to get creative, have a viewing area with pop-up bubbles to simulate seal breathing holes. To balance the roster out, it would be neat to have some additional small animals sprinkled throughout the path; arctic foxes and snowy owls would be neat, trying to fit in badger would keep some ties to Wisconsin native life, and moving some of the Wisconsin fish from the
ARC could give them and guests a fascinating new environment. The set-up could be similar to what Columbus does (used to?) for their American fish, or have the tank situated adjacent to the bear pool much like LA's piranha and otter tanks.
Aquatic & Reptile Center - Once again, this will be mostly fantasy since we know nothing aside from being more reptile-centric. The only comments I'll make for now would be to create a more naturalistic-looking Amazon River habitat with maybe an aquatic reptile (think Fort Worth's large mixed-species terrariums); and add on Komodo dragons - the timing and space voids left behind would be perfect.
Sea Lion Cove - Not much I can say here other than ensuring that the harbor seals remain to create a mixed-species display, and perhaps adding in the American white pelicans for further diversity.
***
The other projects remain as is. Now for some other ideas not in the files...
Adventure Africa - The biggest comment I have for this complex is regarding the aesthetics. There are several extra barriers that I feel take away from the immersive experience and limit the animals; some examples include the cable fence below the elephant viewing, the newly installed metal wiring along the bongo viewing, and the metal railing in front of the hippo habitat (when there's already a small one on top of the mock-rock barrier). I would simply remove these altogether or in favor of something like hotwire, which does the same job but not as noticeable, and fencing with more authentic African-style. Furthermore, a more naturalistic and immersive setting would be more beneficial to simulate the complex's namesake - artificial mudbanks replacing the concrete walls, African artifacts and scenes sprinkled around, and some protected foliage to soften some areas, particularly the elephant habitat. Even giving the elephant enrichment walls another color to match the watering hole could add onto this. As for habitats, I'll go in order of the complex's opened phases:
Phase 1 (elephant area): I'd replace the picnic areas with a small section for meerkats, dwarf mongooses, red river hogs, and warthogs. Instead of cheetahs replacing the former Dall sheep mountain (see next section), the structure could be modified to one of two uses - either klipspringers and hyrax bounding along a kopje-like setting, or giving the vultures more space to stretch their wings would be cool. In addition, bring back yellow-backed duiker in "African Forest." Finally, the biggest change I'd make is to completely replace "Impala Plains" with a larger and more naturalistic savannah, using the current species, moving most of the current savanna and waterhole species, and reintroducing zebras. I'd also find a way to connect the giraffes to this habitat to give them more space (the current habitat can be dedicated to separating individuals and feeding as needed).
Phase 2 (hippo area): I'd rotate the whole outdoor hippo habitat 90 degrees counterclockwise, which was the same way the old hippo exhibit was, so that more space can be provided for the water horses. The educational displays could easily fit in the viewing area or next to the newly paved path. Across from the underwater hippo viewing, it would be neat to tie in some African wetland species such as a cichlid tank (moving from the
ARC) and possibly some African herps like Nile monitor. This would allow extra space to take over the current red river hog exhibit, and allow the hippos access to the future rhino habitat for grazing. Speaking of which...
Phase 3 (rhino area): I would find a way to incorporate some African herps and/or small mammals like elephant shrew in the indoor viewing area. Other than desiring an open view instead of through cables in what was the old elephant habitat, I won't comment any further as this phase doesn't open till later this year. Finally, new habitats for spotted hyenas and serval/caracal can be built wherever possible.
Big Cat Country - I know I sound like a broken record with this one...

With most of the prey species being moved out (Bactrian camels and alpacas can go to
Family Farm), modify the big cat enclosures by expanding them, with more room to roam and more naturalistic experiences. It'll take some work to make them escape proof, but if pulled off properly, it would make for a pretty special improvement to go with the building. Additionally, with jaguar being gone, replacing them with Amur leopard would give the Zoo another cold-hardy species.
Nocturnal Kingdom - One thing that Milwaukee was known for back in the day was that it was amongst the first to create a display that swapped the day-and-night cycle for animals. What better way to honor this than an all-new nocturnal house? This would ring in the return of some species lost from the
Small Mammals Building, bring back some residents from long ago such as black-footed cat and sugar glider, and even newcomers like aardvark and echidna. I don't recall how big the special exhibits building is, but I reckon that may be a solid location.
