TL;DR: QOL change with tall paleo flora options counting towards forest coverage, to increase options for creativity. Add new paleo flora options to help spruce things up, with more variety including things like Araucaria, horsetails, ferns, and Magnolia, and JWE's redwood trees. Edit: Bring back the JWE greenhouse building as well, decorative or functional.
The first thing I want to address is I think a really good QoL addition would be make tall paleo flora count as forest cover. While this is definitely possible in sandbox with comfort turned off, and I suppose I understand why it might be there gameplay wise, but I think changing tall paleo flora to count as forest would be a really good QoL update for the game, allowing more creativity for enclosure design without needing excessively large enclosures, with many of the maps being pretty small as it is. This mainly goes for sauropods, unless their needs are reduced by the humble and social traits, but can apply to anything including carnivores, hence broader creativity. Like as an example, one could use Calamites as the primary forest cover for Dimetrodon, that actually lived alongside them. Other flora like Ginkgos and Tempskya that are a type of tree kind of goes without saying, but I don't see why this couldn't also apply to the Cycad Grove, and Seed Plants as well.
My second thing is that it would be nice to get some new flora brushes to help freshen things up, and give some more variety, and options for creativity. I don't have a lot of suggestions here, but I do think things like Araucaria, horsetails, ferns, and Magnolia would go a long way to increasing the customization we have in the game as far as flora brushes go. Ferns and horsetails were a common staple of many ornithischian dinosaurs diets, and prevalent in a pre-grass world. It's also quite a shame the only map that I'm aware of with a fern brush (though decorative) is locked behind a paywall (the Biosyn DLC map, which I bought back when it released, but still). Araucaria was previously globally widespread from the Jurassic until the late Cretaceous period. It's thought that long necked sauropods may have fed upon them, and evolved their necks to do so, if not with other tall flora. Mangolia might be better as a decorative option, but it was common in the Late Cretaceous Hell Creek formation (of which the famous Ankylosaurus, Triceratops, Tyrannosaurus, etc are from). Of course I'm also not going to forget about the commonly requested Isla Sorna redwood trees that were present in JWE but sort of left out of the sequel. I know there's like a second forest brush type on many maps that is similar, but it would be nice to have the ones in the first game brought back in the second, even if just kept as the decorative placeable trees they were in the first game. Edit: See the greenhouse plants from the first game for some more options, like mosses, and Pawpaw, etc.
Edit: Another last minute thing I thought of, that I know has been requested before, is to bring back the greenhouse building from JWE. It can be decorative, or maybe serve some function, but it is a bit strange that all of this paleo flora we have in our parks doesn't have something that it originally cloned from.
