Tasmanian Trails
A brief interruption in the outback is necessary if your going to avoid a ton of back tracking. You will continue on your journey eastward avoiding the main Australian pavilion to the north. Instead you will head into the slightly smaller Tasmanian Trails pavilion to the south.
So whats in Tasmanian Trails? It will be the home to a wide variety of animals which can be found on the island of Tasmania, obviously. Granted most of the animals can be found on the mainland. I simply wanted a place for two featured animals where if privacy is needed for breeding purposes the zoo can close off the areas without affecting access to a whole pavilion. Plus for the most part this pavilion will be nocturnal. Like my other pavilions it will be filled with native plant species inside the building, sprinklers will give the animals some nice rainfall, and a Tasmanian soundtrack will play on speakers.
As you pass by the front the building you will see the several outdoor exhibits which will display animals through the summer. The first of which will be a larger outdoor aviary. I would like the aviary to actually have huge glass sliding panels which will slide and lock into place in the winter and at night so that the birds are actually snug and secure in the building. It would be a unique little feature for this aviary if its possible. The birds will get nice outside time while being afforded the warmth and safety they also need. If this isnt possible some inside space will need to be converted for them. What lives in this aviary you ask? A variety of birds many of which are considered at risk in Tasmania including, Green Rosella, Dusky Robin, Yellow Throated Honeyeater, Black Throated Honeyeater, Strong Billed Honeyeater, Superb Fairy Wren, Orange-Billed Parrot, Swift Parrot, Cape Barren Goose, Pink-eared Duck, Australian Shoveller, and Little Pied Cormorant. We will be running a breeding facility for all of the at risk species should Tasmania wish us to. The exhibit will be lush but unfortunately if I build the indoor/outdoor type exhibit I want it won't be done with native plants. Again my fear of introducing an invasive species. If there needs to be a separate indoor exhibit then it will be planted with native species. There will be a variety of trees, ferns, lush grasses, flowers, fallen branches, logs, tree stumps, fake trees with nesting cavities, rocks,and a nice deep pond for the waterfowl. I wanted a walk through exhibit initially but if its going to be open to the outside world I don't want anyone escaping.
At this point there is a pathway leading into the pavilion. Two more outdoor exhibits lay to the east and they will house the animal you couldn't do a Tasmanian pavilion without, the Tasmanian Devil. An additional two exhibits would be inside along the pavilions eastern wall. Naturally I do plan on a lot of breeding. The pavilion will house at least two males and two females, plus the most recent young. It all depends on the personalities of the devils. Ideally two or three will be kept together except when joeys enter the picture but if an animal prefers isolation that will be provided to them. In the summer all four exhibits will have devils. In the winter two groups will be rotated out to the breeding center (most likely males). In the breeding center I will have as many more imported devils as I can get my hands on. My goal would be to establish a self sustaining North American population free of the facial tumor that is threatening their survival in the wild. Yes the Aussies are building a safeguard population but I think it would be wise to have reserve populations in North America and Europe too just in case. The more insurance the better for such an iconic animal. I would happily share my stock with any zoos that meet my standards.
Since you have encountered the outdoor exhibits first lets deal with them before heading inside. The devils will have two large exhibits, for animals of their size that is. Guest viewing will be through glass to keep the guests safe from themselves. Inside the grassed exhibit the most striking feature will be a large rock pile at the center of the exhibit. The rocks will provide a lookout which devils love but also hide away places below. Some of the rocks will actually be heating and cooling pads. To provide the climbing opportunities there will also be a fallen branch climbing structure, fallen logs, tree stumps, wood piles, bushes (more so for joeys) and well manicured trees. Up near the guest viewing areas will be ponds about a foot deep for the devils to enjoy cooling off in and heat lamps to help keep them warm on cooler days. Man made tunnels will stretch back into the holding. I could let them dig their own tunnels but I dont want to risk tunnel collapses with such important animals. The exhibit will still be escape proofed below ground but keepers will try to destroy their tunnels whenever possible.
Heading inside the darkness of the pavilion for the first time you will first come across the information station. Here there will be a touch table but more importantly there will be a display on threats to the animals on the island of Tasmania. The biggest display would be on the devils and the threat the facial tumor poses to their survival. Its a great opportunity to show people how important the work of zoos can be when wild populations come under threat. Also covered here can be a discussion on the Thylacine and its extinction. It would highlight the impact people can have on delicate ecosystems.
Beyond the information station along the pavilions eastern wall will be the two indoor devil exhibits. They will be very much like their outdoor counterparts but because the devils will be inside and more active in their nocturnal environment things will have to keep them busier. Yes they will have all of the same dressings but there will also be bones and skins to work their jaw muscles with. Outside that would probably just invite more bugs then I want around such valuable creatures. There will also be birds nests hidden about the exhibit with eggs in them to encourage foraging and climbing. Another interesting feature in these exhibits will be howdy doors so that two groups of devils can interact safely and if a big carcass is brought in for enrichment the howdy door could be opened and everyone share the meal like they would in the wild. But that would have to be keeper approved. At least they could safely visit with each other and keep the males and females in contact with each other so breeding season goes smoothly because of familiarity. Adding more stimulation to the exhibit will the the calls of other devils playing on speakers. This should provoke different reactions. The calls of the other devils will actually be coming in from the devils in the breeding center and the exhibit devils will also play at the center. This should give them a larger sense of community and possibly help with introductions of the devils for mating purposes if they are deemed matches. Just a theory I would like to test. They will get a keeper talk and feeding.
South of the information station will be an Eastern Barred Bandicoot exhibit. A breeding pair will rotate on exhibit. The male by himself unless its breeding season and the female either alone or with her most recent joeys. The zoo would happily establish a breeding program to help with the reintroduction efforts in parts of Australia if the Aussies would like. Joeys born in Toronto could end up in the wilds of Australia which is what conservation is all about. A small breeding colony may be needed anyway do to their short lifespan. Id need a lot of options for breeding to maximize genetic diversity in subsequent generations… that is if other zoos don't adopt their own bandicoots. Due to the shy nature of the bandicoots their exhibit will have to be very carefully designed. Firstly they will have one way glass separating them from guests. This is done purely so the bandicoots can feel like they are all alone which should decrease stress and encourage more natural behaviours. Also being sensitive to sounds guests will find themselves kept back from the exhibit itself by a secondary boundary to prevent tapping on the glass. We all know just putting up the sign saying, “Please do not tap,” does absolutely nothing. Inside the exhibit the bandicoots will have a forest like exhibit. Leaf litter, wood chip and long grasses will cover the floor of the exhibit. rocks fallen branches and logs will create a simple climbing structure for the bandicoots to exercise on. Rotted out tree stumps could provide hiding sites and wonderful places to forage for food. The back wall of the exhibit will have a mural on it.
The bandicoots neighbour will be Eastern Quoll. Like the bandicoots the quolls are solitary animals so while the zoo will exhibit a breeding pair the animals will be kept separately. However I’m not opposed to a single sexed sibling set if they can then be displayed together. Sitting on the corner of the pavilions center block of exhibits there will be two large one way glass viewing panels. This way people will get great views but the quolls will feel secure. They aren’t a shy as the bandicoots but they would probably benefit from the privacy. The exhibit should look like a Tasmanian rainforest to ensure a full array of natural behaviours. It wouldn’t hurt to have a nice mural on the back wall. It will feature a grass and wood chip floor, with bushes, ferns, flowers and a couple of small trees. In both northern and the southeastern corners of the exhibit there would be fake trees with hollow cavities where the quolls can sleep with small one way glass viewing windows. That give them 3 denning options. There will be a rock pile with a small cave underneath providing another shelter. There will also be fallen branches and logs all over to provide climbing structures. Since they hunt mostly in the trees food will be hidden up there including nests with eggs like the devils. Running through the center of the exhibit would be a small stream just deep enough to make them forage for crayfish which would be added for enrichment purposes.
To the south of the quolls and bandicoots will be the one major misplaced animal in this pavilion, the Brown Kiwis. Yes they belong in New Zealand but I just couldn’t come up with enough New Zealand based animals to make a pavilion or even barn focused on them. With the more tropical feel of the pavilion the kiwis will look ok in here. It will be clearly marked on the signage that they are not from Tasmania. I want a ton of kiwis. Ideally I would have space here for at least three exhibits. Each of the exhibits will feature a breeding pair however one pair will be rotated off exhibit if there are chicks that hatch. The chicks will be on display in the center exhibit after being artificially incubated. The chicks will be carefully cared for by keepers but will go on display once they are a couple of weeks old. There will be other pairs, as many as we can get our hands on, in the breeding center. As perhaps one of the most sensitive breeders at the zoo the kiwis exhibit will have to be the most carefully designed exhibits. Special considerations will be total soundproofing of the habitats, specialty one way glass that is sound resistant, a secondary boundary to keep guest from touching the glass, sound resistant flooring such a cork throughout the pavilion (except maybe the main entry which will need to be designed with melting snow in mind), a raised exhibit and location. So why did I put them where I did? I have moved them away from the entrance reducing outside noise, behind the pavilion will be heavy trees marking the boundary of the zoo serving as another sound barrier, they are across the pathway from reptiles and amphibians so less likely to have shouting kids and they are in a nocturnal environment. Lots to consider with them. Inside the exhibits there will be a dirt floor covered by woodchip and leaf litter. Lots of tall grasses, bushes and flowers but no trees. Not like they can fly. To help give them privacy there will be a pair of hollowed out tree stumps to serve as nesting boxes. They will be at the back of the exhibits so keepers can also access them. Underneath the exhibit will be man made tunnels, not visible to guests, leading back to the keepers quarters so keepers can access eggs to be incubated. Rocks and logs can also give them a break from each other. Lastly there would be a small zero entry pool in each exhibit. Just enough they can get wet if they want but more importantly drink easily. Some of the chicks will be trained as educational animals so they can meet and greet with the gusts.
Along the southern wall of the pavilion will be all of the reptiles, amphibians and bugs. I would love to mix and match as many species as possible together but if necessary they can be displayed separately. Species included would be Green and Gold Frog, Brown Tree Frog, Eastern Banjo Frog, Tasmanian Froglet, Tasmanian Tree Frog, Mountain Dragon, Jewelled Gecko, Eastern Three-lined Skink, She-oak Skink, Delicate Skink, and Metallic Skink. There are two other possible additions would be the Tasmanian Tiger Snake and the Fiji Banded Iguana. The tiger snake is highly venomous so its keepers choice. The iguana I just want and figure I will tuck it in here. Another little misplace but they are too cool looking to pass up. All of the tanks and terrariums will feature grasses, rocks logs, branches and ponds of various sizes. Beside them will also be Tasmanian Cave Spiders, Cave Harvestmen, and Mole Creek Cave Pseudo-scorpians. In a lit butterfly aviary (sadly not walk through) you will see Macleays Swallowtails, Small Grass Yellow, Blotched Blues, Pea Blues, Common Grass Blues, Hobart Browns, Leprea Browns, Ptunarra Brown Butterflies, Bright Coppers, Tasmanian Hairstreaks, Australian Painted Lady, Pandani Moths and Pencil Pine Moths.
Back in the center block, to the west of the kiwis and bandicoots will be a mixed exhibit with Tasmanian Pademelons, Common Wombats, Tasmanian Bettongs, and Tawny Frogmouths. The zoo will keep a pair of pademelons, wombats and frogmouths plus their most recent young. Due to the more social though sometimes rough nature of the bettongs there will be 2 males and 6 females, plus young kept in two separate groups. The females for the most part get along and while the male can be a pest with the females having three of them with him should give them each a break from him. The males will be removed when breeding isn’t desired and placed in alternative space. Possibly two smaller exhibits along the reptile wall, possibly just moved to the rear holding somewhere. Keepers choice.
To suit the social needs of the pademelons and wombats there will be two exhibit spaces so everyone can be on exhibit at once. Both exhibits will be extremely similar. Guests will be able to view everyone through half walls angled in and mesh above. This will prevent escapes but let people feel closer to the animals. The two exhibits will only be separated on the ground to the height of the half wall. The frogmouths could easily move between both spaces without trouble so why go to the expense of extra mesh. Another critical feature will be an escape proof base to the exhibit to prevent the wombats from destroying barriers. The exhibit will have clay as its primary base so the wombats can tunnel if they want but man made tunnels will also run under the exhibit too. On top of the clay will be mostly leaf litter, as it is the easiest on bettongs delicate paws, and spots with sand to allow everyone a chance at a dust bath if they want. Plantings in the exhibit would be dense grasses (which the wombats will rip up from time to time but thats fine), shrubs and several good sized trees for the frogmouths to nest in. Hollowed out logs and tree stumps of various sizes will give everyone a chance to hide away from each other. Fallen branches will create a bit of a climbing structure for the bettongs to enjoy if they want. Keepers will need to hand feed the frogmouths for the most part but I would like to try encouraging light hunting behaviours using slugs and snails.
Finally in its own private room will be the one species which I know will astound all guests… the Platypus. Ideally the zoo will get as many breeding pairs of Platypi as the Aussies will let us have and a huge state of the art platypus habitat will be built in the breeding center to work on the mysteries of breeding the worlds most unusual creature. If they are difficult I would take a single breeding pair as my next option with a same sex group being the last option. I would love the zoo to get the world wide recognition that would come with breeding platypi. They will be joined by two pairs Azure Kingfishers who will add a little more life to the exhibit. The kingfishers can show how their species benefits from coexisting with the platypus. I considered cormorants in here but they are exploit the platypus so they would just add stress to the species I desperately want to breed. Also joining them in the water will be Yellow Tiger Yabbies, Red Clawed Yabbies, Mountain Shrimp, Tasmanian Whitebait, Tasmanian Smelt, Tasmanian Mudfish, and others the platypi will be willing to eat. Nothing endangered though. Bigger species of fish could also be added but thats up to the fish curator and platypi keepers to sort out. If the fish are hard to get in any quantity then feeder fish of any variety will do.
Before even discussing the exhibit great care will be needed outside their viewing area. By isolating the exhibit from the rest of the building I hope it will drastically cut down on outside noise. Further reducing noise will be soundproofing all around the exhibits, including rear areas and the walls of the pavilion itself. The visitor area will have the same cork flooring as the rest of the building. Their glass will be sound and vibration resistant. And gusts will be kept back by a secondary boundary. Along the western wall will be the information section including multi camera views of the burrows.
So to give myself the best possibilities of that outside of the breeding center I will need huge exhibits relative to body size. The space I'm talking about is comparable to the whole outdoor kangaroo exhibit. There will be two exhibits with a gate which could open both exhibits to provide maximum space until babies arrive when it would be closed. A chunk of the space will be lost to rear holding but still they will be they will impressive exhibits. Mesh will also separate the flight spaces of the kingfishers so the pairs won't have to fight each other. It wouldn't impact the platypi since they can simply use the underwater gate to travel. The tank will give guests a split level view of the platypi. Part of the viewing window will be underwater while the rest will give a view of the bank.
Underwater the base of the exhibit will be rockwork, fish tank gravel for digging in and rocks with artificial trees, fallen logs and branches to provide obstacles for the platypi to swim around. The water will go below the visitor walkway but just so they have more room. High power filtration should keep the water as close to crystal clean as possible to provide guests with impressive views no matter where in the water the platypi are. They will be given a current machine, waterfall and live prey to spice up their days. This should give them a wide variety of natural behaviours and plenty of stimulation.
Above the waters edge there will be the bank and land area. Part of the bank will be built out over the water providing the platypi their favourite natural spot to eat their meals. It will also double as a place to put kingfisher burrows. They like riverbank burrows to build their nests. A nesting box with trap door lid will allow keepers to clean the nests out at the end of breeding season. There will be a shallow bank in other parts allowing them up on land where there will be man made tunnels for the platypi. The can make their own using the clay soil but I would prefer to encourage them to use any of the man made tunnels so that the burrow can be cleaned and checked on a regular basis. Plantings will include grasses, shrubs, ferns, vines, flowers, and small trees.
Now because I have paired a nocturnal animal with a diurnal animal the light shifting in the exhibit will need to be slightly off the straight reverse. The day will start out as late afternoon and shifting to nightfall around the center of the day. This will hopefully will encourage enough activity. However if the platypi that arrive are willing to be sufficiently active during the day then the lighting will represent a normal day. Another good reason to seal them off from the rest of the pavilion. Since these are perhaps the oddest creatures Im keeping at the zoo its clearly necessary that they get a keeper talk and webcam.
Heading out of the pavilion you will pass by the aviary and mixed exhibit again.
Alien Invaders
Once outside of the pavilion you will notice a small ranch style set up where guests will learn about the alien species which Europeans have introduced to Australia and the devastating impact that they have had on the natural flora and fauna. Naturally we will have to educate people on why the animals came. There would be a display on domesticated animals that have been allowed to become feral or just arent being watched by their owners as closely as needed. These species would include Dromedary Camels, Water Buffalo, Brumbies, pigs, dogs, cats, goats, donkeys, and deer. Then there would be the purposely introduced species such as Cane Toads, European Rabbits, Red Foxes, Indian Mynah, the Common Starling, Rock Pigeon, Carp, Brown Trout, Rainbow Trout, Redfin Perch, Mosquitofish, Weather Loach, Spotted Tilapia Red Imported Fire Ants, Yellow Crazy Ants, Black Portuguese Millipede, Western Honey Bees, and European Wasps. It would be worthwhile to have exhibits for the toads, birds, fish and insects. Just small ones for the animals easy to house and control. Dont need to let them become our own invasive species. Special focus animals will be the foxes, mynah and cane toads which are having devastating impacts on native species. Another good lesson had.
Might tuck a small picnic area in this space.
