The ultimate goal of the modern zoo is to create an exhibit which will promote the well being of animals, encourage natural animal behaviour and allow visitors to develop appreciation and awareness for that particular environment.
The natural environment where an animal or plant naturally lives.
To represent the animal's natural environment, plant species, form, structure, colours and textures are considered. The surrounding landscape allows the visitor to experience a similar habitat to that of the animal they are viewing.
Plants are used to highlight the link between animals and their habitat.
Zoo Horticulturists look closely at the way an animal interacts with the plants in its surroundings. Where possible plants from an animals natural habitat are used in exhibits and surrounding gardens. Sometimes this is difficult so alternative plant species with similar characteristics are used.
Plant diversity and structural diversity are important. This means providing a variety of suitable plant species as well as vegetation layers that includes the ground, middle and canopy layers. An excellent example of habitat simulation can be seen in the Creatures of the Wollemi Exhibit. Here a diverse range of animals are co-existing.
Plant selection can be challenging as most animals like to graze or browse on plants in the exhibit. Plants used within and around the Gorilla exhibit are primarily edible plants
