Abstract:Wild dogs ( Lycaon pictus ) are highly threatened carnivores, and conservation of their dwindling numbers is needed. Isolated populations contribute little to these conservation efforts, so linking populations of dogs is a necessary goal to prevent extinction. I gathered demographic information from a small population of wild dogs in Hluhluwe‐Umfolozi Park, KwaZulu‐Natal, South Africa. Photographs and archive records from 1981 to 1996 were used to compile information on this population. Demographic parameters from the released population were compared with information on wild dogs elsewhere. Most demographic parameters of the Hluhluwe‐Umfolozi Park population were similar to published information from other populations. The main difference was the effect of a single pack on population performance: pack formation was unlikely, unrelated animals were rare, and major losses (emigration and mortalities) occurred. Increasing the number of packs by introducing more dogs would be useful but would be only a short‐term solution. Increasing the local population size and artificially linking populations in southern Africa appears to be the only longer‐term solution to ensure the viability of wild dogs on the subcontinent.
