The goal of nonhuman primate behavioral management is to provide functionally appropriate captive environments that include access to structural enrichment that allows for natural movements. We assessed space use in 3 groups of captive olive baboons housed in 2 indoor/outdoor runs with continuous access to two Primadomes™ connected by a tunnel. We collected 82 hours of group scan sampling data from 58 subjects to assess space use within their dome enclosures (164 30-minute sessions with 3-minute interscan intervals). The baboons spent 72% of observations outside. When outside, for 15% of observations the baboons were at the highest levels of the enclosure (20-25 ft. above the ground); 47% of observations were at ground-level; and the remaining 38% of observations they were using enrichment structures between these two levels, significantly deviating from chance (X2=26.98 (df=2, N=164), p<0.001). The baboons were observed using stationary structures (i.e., perches/platforms) approximately 89% of observations, while using moving structures (i.e., swings) for 11% of observations. Like their wild counterparts, these captive baboons were more terrestrial than arboreal; however, the data show a meaningful number of observations spent above ground-level as well, suggesting that captive baboons benefit from opportunities to spend time off the ground, including options to go quite high (20+ feet above the ground). These data will help inform future captive baboon facility design, ensuring functionally appropriate captive environments.
