With ground being broken soon on the new gorilla and orangutan exhibits, and no known plans for future exhibits after this, it's understandable why many would be speculating on what the future of new exhibits at Cleveland Metroparks Zoo holds, and people have rightfully pointed out some of the zoo's weaker exhibits (pinnipeds, North American bears). As impressive the many recent projects at Cleveland Zoo have been, and as great as it's been to see so many projects improving the lives of their animals, personally I'd like to see the zoo take a new direction in whatever their next project is. All of the recent projects have had one feature in common with each other: a strong focus on one or two charismatic megafauna species. African elephants, tigers, snow and amur leopards, black rhinos, bears and great apes, have all either recently received new exhibits or will be receiving new exhibits in the imminent future. Granted, many of these projects were desperately needed so I can understand why they were priorities.
However, after the Rainforest expansion, I think it'll be time for Cleveland to focus on a project that isn't centered around one or two megafauna species, and instead look for ways to improve the overall biodiversity of the zoo collection. It's important for any zoo, in my opinion, to focus their collection on highlighting biodiversity, and while I have no problem with large mammals in zoos, it is educationally much more important for zoos to highlight the overall diversity of animal life, including birds, reptiles, amphibians, fish, and invertebrates. While all of these do have some representation at Cleveland, the zoo could be doing significantly better in these categories, and focus on highlighting species other than large megafauna. While I can understand why some may want to see sea lions or more bear species as focuses of future projects, I'd much rather see the zoo phase out those species, as they already have a strong array of megafauna on display, and instead work on a project to improve the overall biodiversity of the zoo.
I'd love to see the zoo design a modern reptile and amphibian center to the likes of Atlanta and Knoxville's new buildings, or see Cleveland's take of either an aquarium or an insectarium. Even if another mammal-focused project is in the works, a focus on smaller mammals instead of megafauna would be appreciated. Turn PCA into a dedicated Madagascar exhibit, as the zoo has fossa and a strong collection of lemurs already, and could benefit from the addition of Malagasy herps, inverts, birds, and fish to the area as well, or double down on its nocturnal primate exhibits and build a dedicated nocturnal building- a style of exhibit that is still impressive even if it has fallen out of favor lately. There are plenty of great possibilities for projects that Cleveland can prioritize going forward, so I'd hate to see another project that focuses on only the megafauna and neglects the fact that most animals are not large mammals.
