| Release in Pilanesberg NP - Diceros bicornis. Males seemed less inclined than females to explore remote parts of the reserve. Males settled in the main valleys near the release sites, while females found ranges in suitable areas throughout most of Pilanesberg. |

| Release in Pilanesberg NP - Diceros bicornis. During the early introductions, the abundant space available to the rhino meant that when conflicts arose, there was room to escape. This probably played a role in the success of these early staggered reintroudctions. Subsequent changes in rhino ra... |

Black Rhino

| Release in Pilanesberg NP - Diceros bicornis. The number of fighting incidents among the male deaths (5 cases out of 15) suggests that social pressure is a significant factor. |

Black Rhino

| Pilanesberg NP. Average observed inter-calving interval is 34 months or 2.8 years.
The most likely mode is 2.6 years, from 20 observations, range 2.1 to 5.8 years.
Intercalving interval is thought to decline with female age, but there is no indication of this yet in Pilanesberg. |

Black Rhino
|
| Males from 8-10 yrs old and onwards, they wandered further afield than before, their ranges still overlapping each other and those of old bulls. It is supposed that by this age the males still have not established their home range or territory. |

| Release in Pilanesberg NP - Diceros bicornis. The experience from Pilanesberg suggests that there is a limit to the number of males an area can carry. Excess males should ideally be removed to pormote population performance in a restricted area. However, these surplus males cannot always be pl... |

Reproduction
Black Rhino
|
| Pilanesberg NP. Average age of first calving was 7.5 years, range 6.8 to 8.8 for 7 females. Body weight is known to affect fecundity, and young rhino would need to approach 80% of their adult body weight before successfully conceiving, which is usually when the female is about 6.2 years old. |
