A much greater emphasis is now placed on the quality and detail of environment replication, not only to increase the visitor experience and understanding but also to provide a low stress but stimulating environment for display species.

There is a trend towards larger displays where the visitor is actually immersed in the environment which is an extension of the exhibit.

Use of large dioramas has become common with quality and presentation of the subject matter dependent upon the cultural character of the majority of the visitors.

The theme concept will strongly influence the type, detail and extent of environment replication.
