Plants for Enrichment
Often, animal enclosures include plants, yet plants (or parts of plants) are not employed specifically for enrichment. An extensive article by Frediani (2009) discusses the many ways in which plants can be perceived. Auditory, visual, olfactory and tactile stimuli are reviewed, as well as the manner in which plants can be used for determining location and time. In addition, benefits of using plants instead of artificial structures are named: one example is providing climbing materials (regenerative, soft, dynamic, and relatively inexpensive).
The author of the article makes a case for more conscious use of (parts of) plants for the purpose of enhancement for animals in captivity. It is possible to put the examples described in the article to use immediately.
