Giraffe translocation population viability analysis
Most populations of giraffes have declined in recent decades, leading to the recent IUCN decision to upgrade the species to Vulnerable status, and some subspecies to Endangered. Translocations have been used as a conservation tool to re-introduce giraffes to previously occupied areas or establish new populations, but guidelines for founding populations are lacking. To provide […]
All the eggs in one basket: A countrywide assessment of current and historical giraffe population distribution in Uganda
To design effective conservation and management strategies at the national scale, it is important to consider population trends across space and time. Here we assessed the near threatened Rothschild’s giraffe (Giraffa camelopardalis rothschildi) in Uganda. We applied individual-based photographic surveys to generate abundance estimates for all extant populations, using either mark-recapture estimates or complete enumeration, […]
Letter From Namibia
The modern giraffe (Giraffa camelopardalis) is the world’s tallest animal and its largest ruminant. It is also among the most quintessentially African of animals, being found throughout most of the continent—the greatest concentrations in eastern and southern Africa. Yet, since the dawn of the new millennium, a combination of habitat loss, habitat fragmentation, civil unrest, […]
The past distribution of giraffe in Zululand and its implications for reserve management
The evidence for the past distribution of giraffe in Zululand is critically re-examined. On the basis of this, it is concluded that the probability of giraffe having ever occurred in Zululand prior to their introduction is extremely small. As a consequence of this, and according to the definition of an indigenous species favoured by us, […]
Identification of novel Babesia and Theileria species in South African giraffe (Giraffa camelopardalis, Linnaeus, 1758) and roan antelope (Hippotragus equinus, Desmarest 1804)
Blood specimens were received from five cases in which young adult giraffe, from different geographic origins in South Africa, showed sudden onset of disease and subsequently died. Additional specimens from two translocated giraffe, as well as one specimen from a roan antelope, were also included in the study. Blood slides from some of these animals […]
Operation Twiga: Zoos supporting Rothschild’s giraffe conservation
Giraffe are one of the iconic megavertebrates of Africa but have not been seen as a conservation priority until recently. In December 2016, the International Union for Conservation of Nature (IUCN) reclassified giraffe from a species of Least Concern to one that is Vulnerable to extinction. Population surveys indicate that giraffe are suffering a silent […]
Analysis of Angolan Giraffe (Giraffa camelopardalis angolensis) Post-Translocation Movement Patterns and Implications for Conservation Management in Namibia
Wildlife translocation is a conservation management strategy that has been employed to bolster many diminishing wild animal populations. Giraffe translocations are currently being conducted in Africa, but the consequences of such remain largely unknown. In Namibia, translocations are conducted to re-establish locally extirpated populations or to recover vulnerable ones in and around communal conservancies. This […]
The reaction of a group of Rothschild’s giraffe to a new environment
The behaviour of a translocated group of 11 Rothschild’s giraffe (Giraffa camelopardalis rothschildi Lydekker) was studied for 9 weeks in 1968. A comparison was made between their new and former habitats, the food plants eaten in both places, and behaviour. For 3.5 months after release, they appeared to have settled in the area, but they suddenly […]
