From San Diego Zoo Safari Park to the Serengeti

  • Grumeti Fund translocates a 1,157 kilogram eastern black rhino bull from San Diego Zoo to the Serengeti, Tanzania
  • The epic 68-hour journey spanned five countries, requiring three aeroplanes and two trucks

An eight-year old eastern black rhino male from San Diego Zoo has been successfully translocated to the western Serengeti, in an effort to save this critically endangered species from extinction. Bred in the US, ‘Eric’ is now safe and well in the Singita Grumeti Reserve after an epic journey from LAX, via Belgium, Doha, Uganda and finally into Tanzania. With fewer than 750 black rhino remaining, the translocation completes the first phase of the Grumeti Fund’s Black Rhino Expansion Project.

The Grumeti Fund has successfully planned, organised and coordinated the translocation of Eric, an eight-year-old eastern black rhino male from the San Diego Zoo Safari Park to the western Serengeti. Tanzania’s newest resident was gifted to the government and the people of the United Republic of Tanzania by San Diego Zoo and to bolster an important satellite population of critically endangered eastern black rhino within the greater Serengeti ecosystem. Eric’s new home is the exclusive 350,000-acre Singita Grumeti concession area in the western Serengeti where he will be protected and monitored by the non-profit Grumeti Fund in close cooperation with the Tanzanian Wildlife Management Authority (TAWA).

It took two trucks and three airplanes, across five countries to get the 1,157-kilogram bull rhino back to his native habitat – an epic journey in which he travelled extremely well. “Our months of preparation for Eric’s travel were successful and the transport could have not gone any better,” said Steve Metzler, Henshaw curator of mammals, San Diego Zoo Safari Park. Eric arrived safely in Tanzania after an epic 68-hour journey which included a truck to Los Angeles International Airport where he was cleared by US customs and put on a wide body aircraft flight through Belgium and onto Doha where he was offloaded for ten hours. From Doha, Eric then flew to Uganda and finally on to the Serengeti, Tanzania. Now safely in Singita Grumeti, Eric will reside in a rhino Intensive Protection Zone, along with another eastern black rhino female. With the help of a rhino behavior specialist, he will become acclimatised and sensitised to his natural environment over the next several months.

“This translocation is significant because Eric is genetically over-represented within the American zoos’ East African rhino population, yet he will play a vitally important breeding role in the wild Tanzanian population. We are hopefully going to see a lot of movement and mixing of the various satellite rhino populations in the ecosystem, where his impact on the genetics of the overall population will be crucial,” says Grant Burden, Head of Special Projects, Grumeti Fund.

Fueled by a lucrative illegal trade in wildlife products, Tanzania experienced a poaching crisis, which decimated rhino populations, and today fewer than 750 remain across the whole of East Africa, classifying the eastern black rhino (Diceros bicornis michaeli) as critically endangered on the IUCN red list. The Grumeti Fund has had tremendous success in curbing poaching since its establishment in 2003, which has resulted in dramatic increases in wildlife numbers. Between 2003-2018, the concession experienced a four-fold increase in elephant populations and over a ten-fold increase in buffalo numbers. With a strong anti-poaching presence in place and plenty of ideally-suited rhino habitat, under the co-management of the Grumeti Fund and TAWA, the Singita Grumeti rhino expansion project is ideally positioned to meaningfully contribute to repopulation and protection eastern black rhino within the greater Serengeti ecosystem.

The Grumeti Fund will work in collaboration with the Ministry of Natural Resources and Tourism’s Wildlife Division, Tanzanian Wildlife Management Authority (TAWA), Tanzanian National Parks (TANAPA) and Tanzania Wildlife Research Institute (TAWIRI) to successfully implement and monitor this multi-phase project. The IUCN Species Survival Commission Guidelines for the in-situ re-introduction and translocation of African rhinoceros will act as the road map for this on-going translocation project.

The establishment of a viable satellite population of breeding black rhino within the Singita Grumeti concession area by mid-2019 is expected to provide the stimulus for rhino population growth with dispersing rhino venturing out and recolonizing new territories within the greater Serengeti ecosystem. As Stephen Cunliffe, Executive Director of the Grumeti Fund, concludes, “Our ultimate goal and measure of success for the Singita Grumeti Black Rhino Expansion Project will be to have these reintroduced rhino breeding and thriving within their natural environment to the point where they start to disperse, and we see movement occurring between the various satellite rhino populations within the wider ecosystem.”
