Preference for structural environmental features in captive lowland gorillas (Gorilla gorilla gorilla)* (1993)

Ogden, J. J., Lindburg, D. G., Maple, T. L.

Abstract

The results indicate that enclosure usage was significantly associated with the features of slope, nearness to holding facility, and presence of environmental components additional to substrate (e.g., tree or rock). In particular, areas with flat ground that were near the holding building and that included at least one component additional to substrate were preferred by all animals.
