Among the many conservation successes made possible by Malilangwe’s unique ecosystem and data-driven management approach, few are more significant than the recovery of the critically endangered south-central black rhinoceros (Diceros bicornis minor) and the near-threatened southern white rhinoceros (Ceratotherium simum simum).

Our Rhino History

Following the local extinction of both species due to poaching in the late 20th century, Malilangwe successfully reintroduced black and white rhino to the reserve in the late 1990s. In 1997 and 1998, conservation teams translocated 12 white rhinos and 28 black rhinos from South Africa to Malilangwe. After spending time settling in the bomas the rhinos were released, and by the end of 1998, Malilangwe welcomed its first black rhino calf. Since then, countless calves of both species have been born, and thanks to intensive protection of these calves by our Scouts, Malilangwe’s nutrient-rich soils, and close collaboration between our research and wildlife management teams, our rhino population has grown roughly tenfold.

Today, Malilangwe supports one of the highest densities of rhino in southern Africa, providing us with a unique opportunity to contribute to rhino conservation beyond our borders through carefully managed translocations to suitable ecosystems. To date, we’ve translocated 71 white rhinos and 18 black rhinos from Malilangwe to other protected areas to help reestablish rhino populations across Zimbabwe and Botswana.

Ear Notching

Understanding the dynamics of our rhino populations establishes the foundation of informed, science-based management. We ear-notch each of our rhino so that the notches correspond to a unique identification number, allowing scouts and wildlife managers to track every individual’s movement, behaviour and – for females – reproductive performance.

Scouts collect most of the rhino observation data as part of their combined security and wildlife monitoring duties. While on daily patrol, they record every rhino sighting. They document locations, behaviour, noteworthy events or observations and the details of other rhinos in the group.

All of this information feeds into a custom-built database that now holds more than 25 years of detailed records. We can generate reports, run queries, and produce distribution maps from this system to guide scientific decision-making. By understanding the lineage or each animal, we can select for genetic diversity when choosing animals as founder populations for other conservation areas.

Rhino Research

Our commitment to rhino conservation extends far beyond safeguarding the individuals that call Malilangwe home. Through pioneering research, we are helping build a deeper understanding of both black and white rhinos, generating knowledge that supports the long-term survival of the species across Africa. The more we learn about rhinos, the better equipped we are to protect them, translocate them, and ultimately help establish thriving populations in suitable habitats throughout southern Africa.

A powerful example of this work is the research being conducted by Sarah Clegg, an ecologist with nearly three decades of experience monitoring and managing Malilangwe’s rhino populations. As part of her PhD studies in black rhino social biology, Sarah has made important discoveries about the influence of individual relationships on behaviour, ecology, and population resilience in both black and white rhinos.

Her most recent findings challenge long-held assumptions about rhino social dynamics, revealing that social connections play a far greater role in their lives than previously understood. This research is already helping to refine Malilangwe’s rhino translocation strategies, enabling more informed decisions that improve animal welfare and increase the likelihood of successful population establishment.

Once published, we hope Sarah’s work will help improve rhino translocation practices across Africa, contributing to more successful conservation outcomes and healthier, more resilient rhino populations for generations to come.
