After the rhinoceros has been bred there has been problems in their post-release survival. The biggest reason for the rhinoceros dying (post-release) was because of intraspecific conflict which consists of the rhinos fighting. This graph below shows the difference in rates among the rhinos.
There is also a difference in the rhinos deaths from restocking and reintroduction. The term reintroduction is where the rhino is released into its native area from where they had disappeared. Then, restocking is releasing the animal into the area where there are only a few left of the species. The mortality rate of rhinos post-release is much higher when restocking the animals. The rates are almost quadrupled in the rhinos that are less then 2 years old compared to the rates of mortality in reintroduction.
