Colchester Zoo has become well known for its modern, ground breaking enclosures for its animals and has won many awards for its innovative designs.
When designing a new enclosure, a number of factors have to be taken into account, including all the needs of the species that you are designing the enclosure for ie the number of animals the enclosure will house, its welfare and safety.
The needs of the visitor also need to be taken into account to incorporate covered areas for wet days, maximising the potential for animal viewing balanced with an animal’s requirement for privacy.
All of the needs of the species are taken into account when designing an enclosure; such as their behaviour, reproduction, habitat, feeding, and activity. For example, an animal that lives in the trees needs to be provided with lots of opportunities for climbing on ropes and branches.
Normal group size of a species is taken into account when deciding how many animals are to be housed in the enclosure, which in turn affects the design.
For example, a solitary animal, such as a tiger, will generally be kept on their own, while the aim is to keep social animals in suitable groups such as most primate species. It is important to provide them with sufficient space to sleep, feed, play and have enough space to reduce the chances of conflicts occurring within the group.
Considering the behaviour of the animal in the wild is also important, if an animal rears its offspring in a burrow or cave then it is important to provide them with similar surroundings in their enclosure. Ideally the enclosure should reflect the environment that the animal comes from which can be achieved by using furnishings, such as plants and rocks in the enclosure. This will encourage natural behaviours such as climbing, foraging and digging.
Temperature, lighting and humidity must also be suited to the specific animal and should relate to natural cycles, some animals that are found in hot deserts in the wild are provided with an indoor space only which can be kept at a constant temperature and monitored.
You can read about some of the enclosure designs at Colchester Zoo below:
The enclosure is equipped with a sliding roof system made from UV transmitting panels and can be opened or closed according to the weather conditions. The enclosure is heated with a mixture of underfloor heating systems and heat lamps. In combination with this underfloor heating, the keeping staff spray tepid water around the enclosure to create the correct levels of humidity that this reptile species requires.
Both indoor and outdoor sections of this enclosure have viewing areas along with the educational information and activities that link to the species.
The two bears this area houses have a large outdoor area for them to explore, along with an indoor area consisting of a waterfall and climbing frames for enrichment. Both the indoor and outdoor areas for our sun bears have public viewing areas, but the animals also have the opportunity to retire to their own private, off show, sleeping quarters if they wish.
