As per Article 13 of the EC Lisbon Treaty, all animals are recognised as sentient beings and Member States shall pay full regard to the welfare requirements of animals. Equally in the Directive, all zoos should maintain high standards of animal husbandry and provide:
“. . . species specific enrichment of the enclosures . . .”
(Art. 3. European Council Directive 1999/22/EC)
The opportunity for animals to express their normal behaviour is recognised as a basic and essential biological need (Five Freedoms). This Section of the evaluation was designed to provide an assessment of the welfare of each individual animal within the selected enclosure (refer to "enclosure quality" left). This included an assessment of the condition and behaviour of the animal at the time of assessment and sought to determine whether the enclosure offered the potential for the individual animal to express its full repertoire of natural behaviour.
Although it is recognised that an quantitative assessment of animal behaviour is a longer term process that should be carried out under controlled experimental conditions (not possible in this evaluation) the method adopted did provide a simple way of judging an animal's overall welfare state, partly based on the suitability of the structures and materials within the selected enclosure. The following tools were used:


It is widely recognised that animals kept for prolonged periods in ‘impoverished’ captive conditions can develop stereotypic behaviours: behaviours that are ‘repetitive, unvarying, with no obvious goal or function’¹.
Pacing, rocking, swaying, bar-licking and other compulsive behaviours, may arise as a result of captive environments that compromise (or have once compromised) an animal’s welfare. In this study, the investigators recorded stereotypic behaviours when the animal displayed at least five cycles.

Evaluation of Animal Well-being was undertaken using Section E of the Zoo Assessment Protocol
