Wombats at Hamerton Zoo Park

Recently we got asked to make the habitat for an animal which we have never worked with before. New animals are always exciting because its kind of cool to be able to ‘tick them off the list’ Some animals are even more exciting than others though.

There is something special about Australia for many of us Brits and ones with an interest in plants and animals, maybe more so. Australian fauna is strange. The animals don’t seem to fit with the other ones around the world and if they do have similarities, they will also have some strange difference like a pouch for their young for instance. You know, kangaroos could easily have come from the same evolutionary branch as rodents or lagomorphs but they didn’t. They are totally unconnected, at least not in recent evolutionary history. I know it’s because how the land masses separated but it’s still weird. And interesting.

Wombats

When Hamerton Zoo Park contacted me and told me about their plans to bring some mainland wombats from Darling Downs Zoo, Queensland, my first thoughts were that they would be the only ones in the U.K. I knew this because a year before, I had visited Australia Zoo and viewed the environment they had built for the species there. I remember thinking what an interesting animal and it would be cool to work with these. It turns out that no wombats have been in the UK for over thirty years and the last ones had been at London Zoo in 1985. So imagine my enthusiasm when I realised that not only was it a new species for us but it was also Australian and the only ones (here at least).

The build

There wasn’t too much to design as HZP had a clear plan for what was expected. A series of 4 off exhibit tunnels leading to sleeping chambers (with special viewing windows for the public) and an open paddock separated by a semi-transparent fence. The building, which was a new structure built especially for the exhibit, had low concrete block walls which needed to be themed and beautified.

Earthbank theming

Wombats can climb (not very well) so part of the brief was to make the low walls unclimbable for a large heavy lump animal with short legs. Where they are not great at climbing they make up with digging. They spend a lot of their time digging when they are not sleeping which is the rest of the time. It was decided to theme the walls as eroded earth bank which would fit in well with the natural habitat and also compliment the look of the enclosure due to their fondness of earth moving. Each wall would have a slight overhang and the top of the fake earth bank would also incorporate an irrigated planter. Mixing planting with theming really adds to the naturalness of zoo habitats and I always encourage this in the design stage.

We set to work and built a steel armature to resemble the eroded earth bank we had in mind and carefully made the shapes in a way that the animals would not be able to get a foothold and escape. You have to think carefully when adding relief, it has to look natural but also serve a practical purpose. We sprayed on two thick layers of our standard shotcrete and made any extra texture by manipulating the wet concrete with water from a hose. Final colours were achieved with UV stable acrylic paints sprayed over several watered down layers in a wash method to achieve the look of the crumbling earth. Then it was a long wait until the animals arrived. The wait was worth it though when we saw these beautiful animals enjoying their new surroundings.

Massive thanks to Hamerton Zoo Park for having us (It feels like our second home and we are always made super welcome!) and Rob Cadd for his excellent animal shots.

Trees for orangutans

Koda Creative was invited to join the multi skilled team at Houthoff Zoo Design to help build twelve giant trees in the new Orangutan Forest exhibit at Dublin Zoo.

The trees are copies of the kapok and banyan trees found in the Bornean orangutan’s natural habitat, the tropical rainforests of Borneo. Each tree is made from steel and concrete and the details are hand sculpted and painted. Three trees contain feeding systems which encourage the apes to climb high in search of treats. The tallest tree is 12m high and all offer climbing opportunities for these mainly arboreal animals. Some trees are connected by cables which the orangs can traverse across high above the heads of the humans below.

In the wild, these animals are losing their homes because of deforestation due to palm oil cultivation. Dublin Zoo hopes The Orangutan Forest enclosure will help highlight their plight and raise money for the Orangutan Foundation.

There is some more information about this exciting new exhibit on the Dublin Zoo website.

Rock for gundi exhibit

Gundis, sometimes known as comb rats, are small rodents which are native to North Africa. They are unusual in the fact that they don’t drink water. They get all their moisture from their food. They also like to chew stones so we a had to make a very strong mix for the artificial rock here.

We made an EPS armature (shape) and coated it with a very hard fine concrete mix. On top of this there is a finer ‘carve’ render which is given the rock texture and coloured. We also built in recesses for heat lamps. Electric conduit tubes were built within the rock so the electrician could easily connect later.

Thanks to zoo keeper Alina Kallio for the animal photos. Check out Alina’s and Timo’s blog here Frog Trail.

Amazon waterfalls

The image below is a photo of a small waterfall we made in an amazon themed aviary. The trees to the left are 7m high supports for the stainless steel mesh structure and inspired by buttress trees Ceiba pentandra. The buttress trees and rockwork are made from steel, concrete and shotcrete. The brief for this project was to imagine what a small Amazon Rain Forest tributary waterfall might look like.

To make this artificial environment, we searched on Flickr for ‘amazon waterfalls’ and the following images are amongst what we used for artistic reference. I wanted to post these pictures to show part of the process we use when researching a zoo enclosure project. I hope you think we faithfully reproduced our little imaginary part of the Amazon Rain Forest.

To recap, the image above is fake and the ones below are real.
