Association rates were negatively related to reserve size and positively correlated with release density. We conducted a science-by-management experiment on the influence of reserve size and release density on rates of movement, association, and injury and death amongst 39 black rhinos during the first 100 days after their release into 4 Namibian and 8 South African reserves ranging in size from 670 ha to 45,000 ha. ![]() Smaller reserves and higher conspecific density after release (release density) might increase a rhino's encounter rate with hazards like fenced boundaries and conspecifics. Fighting and accidental injury commonly cause black rhinoceros (rhino Diceros bicornis) death after release.
