I don't imagine the Hoofstock situation is related to Elephant Trails purely because the master plan places that exhibit over parts of mostly other exhibits, and Australia and Pachyderm House don't look to be going anywhere. The lack of funding for such an ambitious project is probably going to hold off elephants for a long, long time.
I look forward to finding out what new species will hopefully be rotated in, but it's going to take getting used to on my next visit for sure. The Habitat Africa exhibits (and the Swamp a bit) both certainly feel a little undermined by the last decades of development at the zoo, as some of the choices made with regards to moving or rotating in/out species seem to undermine the intended exhibit themes. I love crocodiles and addax, but it's still off seeing them in exhibits that clearly were not designed to replicate their native habitat.
Really, I just wish they could afford to knock down or re-develop the Bear Grottos. The south right section of the zoo is so empty these days, and pretty much is entirely if you skip Wild Encounters, and the huge fence is unsightly. I imagine the zoo would rather focus on new African habitats or the much-needed Tropic World renovations, but it might be a great place to create something different, since the opposite side top left will eventually be dedicated entirely to Africa. The top left seems reserved for Asia, and the bottom left is North and South America... which leaves Australia as a suitable option, given the existing exhibit will need to be cleared for Africa... but I can't imagine them spending the money on that.
Speaking of Wild Encounters... the Red Panda situation is ridiculously grim. It doesn't sound that Brookfield is doing anything incorrect, and yet, they seem off to a terrible start with the species. Isn't this the second or third time they acquired a new panda only for the previous one to die? And the exhibit's relatively recent, with pandas being a key highlight. Horrible news.
