Individual Methods for Enclosure Design
Hessian Sacking

The methods outlined in this section relate to features of enclosure construction and layout which may be used to enhance the living conditions of animals, including the use of shelter areas, vegetation, viewing platforms and climbing structures.

Hessian Sacking

Method Vertical strips of sacking create a screen between locations within the enclosure, and to the public area.
Species Primates.
Purpose Provide a visual barrier from the public, and also. between dominant males and juvenile/subordinate males, to reduce threats and aggression.
Pro Very cheap.
Con Does not last long with destructive species. Where the dominant male controls aggression with stare threats, could result in more serious disputes ‘behind his back’.
Improvements Tie knots onto the bottom of strips, with or without peanuts inside. Some primates, for example, Allen’s Swamp Monkey spend a long time unpicking knots.
Comments A juvenile male Diana Monkey has been able to remain within the group until at least 5 years of age without problems arising with the dominant male.
Frequency of Use Constant.
