AAAAND we're back for part 2
I'm going to continue my description from the stepping stones onward, as this path converges with the top route of the split path. After we've taken an underwater look into the waterfall basin, the route goes past a group of islands with fallen logs, these are surrounded by shallow water and doesn't house any creatures in particular, though it is designed to attract some of the free-roaming birds like Sunbitterns, Spoonbills and Ibises. After these islands are two waterfalls, which are also visible from the bridge. The paths come together and lead to a rock arch, where some ropes hang over the path to block birds from getting into the next region: Caiman creek!
Caiman creek is a separated region of the Rio Dourado, large netting surrounds the area, designed to keep the larger birds away from the predators. Though smaller birds, like grassquits, manakins and honeycreepers, still have access to this area.
Inside, there is also a free-roamer inside the area that cannot free-roam in the larger hall. This would be the Caiman lizard.
You can take the path downward to an underwater viewing area, where you can see a large group of Piranha, along with other fish and some turtles. On the other side of the viewing window, the side of the river is rocky and steep. With, once again, a large fallen tree sitting in the water.
You can take the path back up and follow two routes. One route goes over a small boardwalk, which provide a better view of the main inhabitants of this area: Cuvier's dwarf caimans. The side of the river on the other side of the boardwalk is a sloping beach. This way you can see the Caimans and turtles above water on this side, and under water on the other side.
You can also walk through a jungle area, which has another small pool, which is designed for the Caiman lizards. The Caiman lizards can also swim in the main river, which is accessible through a thinner log, which can be climbed up and down by the lizards, but not by the caimans.
When the path and the boardwalk come together, we encounter another rock arch with ropes. This leads into another separated area with an extra warning sign:
Warning: You are now entering Snake Territory. Welcome to Serpent pass.
Like Caiman creek, Serpent pass is separated from the rest of the greenhouse. But this area is a little more fortified. Instead of large netting, this area is surrounded by thin mesh. The central enclosure in this area is home to Green Anacondas. The river area on the visitor's side is designed with a slippery metal overhang, which should prevent the large snakes from getting out. The top is covered with hanging plants, which makes it more natural to the visitor's view.
The normal path goes down and leads to another underwater viewing area, this one being under the boardwalk area, meaning we can't see it from the top view. Here, we can see Knifefishes, Cichlids and multiple catfish species among others.
No birds can get into serpent pass, as this area is even more unsafe than caiman creek. The free-roamers here are what give the area it's name, and the warning sign it's meaning.
Free-roaming here are three species of boas, as well as Poison frogs and some butterflies to give the region some more colour.
Separate from the river are two small waterfalls. One waterfall (waterfall 5 on the schematic) runs along the rock wall, this is the typical type of rock waterfall often found in paludariums for Dart frogs or Vampire crabs.
A larger waterfall (waterfall 6 on the schematic) flows downhill into a small pool, which should provide a bathing area for the boas.
After this waterfall, there is a small hut to be found on the side of the rock wall, this holds the chrysalises of the butterflies. After this the paths leads under a final rock arch, which brings us back to the main hall.
Both Serpent pass and Caiman creek have two caretakers to make sure the reptiles don't escape into the main hall, as well as to make sure visitors don't see the reptile's slower movements as an invitation to pet the wildlife. These are also here for education purposes of course. Some educators are also present in the main hall, some of which follow particular free-roamers for similar reasons.
Before we continue, we're going back to the split path, this time we walk further through the Rio Dourado's main area rather than the separated areas.
Taking the bottom path we again find ourselves going over a bridge over the main river, this provides a final view into the Paca beach area on one side, and a small island on the other side. This island has a few wooden climbing structures hanging over it, which allows for some of the mammalian free-roamers to more easily get to the other side of the river. Similar structures can be found near the monkey islands.
We go over a second bridge almost immediately, this brings us close to a final separated enclosure. A small viewing gallery, in the shape of a shabby jungle hut, allows viewing into the steel mesh enclosure, which holds Ocelots. The small cats also have access to a small part of the river for swimming, with once again a fallen log which acts as a climbing structure.
In the back of the enclosure is another small hut, which is a multi-purpose building. As it's also the drainage of the large basin at the end of the river, from here the water leads into an underground filtration system that cleans and pumps the water back to the larger waterfall at the beginning of the river.
The route goes further along some rock walls, which has mosses and hanging plants to make it more natural. These hide the the separated areas, of course.
We encounter the final bridge of the greenhouse, which goes over the main basin. With some luck you can actually see one of the mighty Arapaimas swimming below you.
The final area of the greenhouse is clearly inspired by the viewing window in Burgers' Mangrove, I can't deny it. The main path slopes down for a bit, which leads to a larger slope area into the lowered viewing area. Two staircases lead back up to the main path, which almost immediately leads to the exit of the greenhouse.
The viewing window is nearly 20 meters wide and provides underwater viewing into the deepest area of the river. A small island in the middle as well as, as you might guess, more fallen logs provide sitting spots for some of the turtles in this area. Though this area does have more aquatic turtles in comparison to the rest of the areas.
This main basin, basin F, has the most fish species with 18 different species (one more than the main river area, basin C, which has 17). These include some of the Amazon's largest river monsters, with Arapaimas, Redtail and Ripsaw catfishes and Speckled peacock bas among some other very large animals.
The area around this final path and the main basin has some large, rounded rocks. Which are mostly for aesthetic, but partially also to make the height differences between the main path and the underwater viewing more natural-looking. As well as providing heating spots for the greenhouse's cold-blooded animals, and perching spots for some of the larger birds.
For the broad explanations I'm going to place the Schematic version again.
Numbers 1-6 are the different waterfalls, and letters A-F are the different basins.
Waterfall #1 starts the river. It's the biggest waterfall and it flows into Basin A, the waterfall basin. The waterfall is similar in height and amount of water flowing out of it to
one of the waterfalls in Rimbula River. A smaller waterfall also flows on the other side of the basin A, near the underwater viewing area.
Basin A is roughly 1.5 meters deep, meaning you can view both under and above water of the basin.
An underwater pump pumps extra water into the waterfall basin, meaning that waterfall #2 actually has a lot more water flowing through it than waterfall #1
Waterfall #2 flows from Basin A to Basin B. Basin B is the shallowest part of the river, and includes the least fish. Only being home to some small fish like guppies and pencilfish.
Waterfall #2 has a rock in the middle, splitting the waterfall in two. The waterfalls are roughly 2 meters tall. Because of the large amount of water flowing through the waterfall and the shallowness of Basin B, this area of the river is the most fast-flowing, though it is slightly slower in the island area.
Waterfall #3 is another split waterfall, this time being split earlier than the ledge thanks to one of the islands. A large log sits between the two waterfalls. These waterfalls are roughly one meter tall and flows into Basin C. It is the last waterfall in the river, so the rest of the basins are a lot more calm. Though they do still flow, as the water eventually comes all the way around to the multi-purpose building in Basin F, where it is pumped back to Basin A.
Basin C is the largest, and includes a shallow area at Paca beach, and a deeper area from the underwater viewing log to the monkey islands.
Basins D and E are separated by underwater mesh. This is of course done to hold the aquatic predators, but also to hold in the fish to make sure every underwater viewing window has a unique species lineup. The basins have no real difference in side or depth in comparison to Basin C.
Basin F is the final basin, and has the largest single area. The basin starts in a river area, which is slightly more shallow, though still easily accessible to the monster fish inhabiting the basin. The larger area of the basin is the deepest area of the entire river, being four meters deep at the deepest point. Though the viewing window here is only two-and-a-half meters tall.
I already described waterfalls #5 and #6 of course. And waterfall #4 is nothing special. It's
only a small waterfall of roughly 1 meter tall made to start the stream to keep the marmosets into their enclosure.
I'm fairly certain I've described everything now. Apart from the foliage, I supppose.
The foliage map (in the beginning of this post) represents the visitor's viewpoint, not the top view. The dark green areas of foliage are the really heavy foliage, including trees, bushes and other non-see-through foliage. Light green areas are lower ground foliage. Tree cover and vines with hanging plants would still cover the top view, of course. The foliage, on top of the usual greens, also includes some colours like lobster claws and bromelia plants. There are also a few palm-like plants (Including Acaí palms and Banana plants) and fruit trees like Papayas and Avocados.
The underwater is also heavily planted with multiple Amazonian plant species, including a lot of Amazon sword plants.
