Population ecology of Maasai giraffe (Giraffa camelopardalis tippelskirchi) in relation to climate variability in southern Kenya.

Wildlife populations and their habitats are facing serious threats from global changes in climate and human development activities. Large herbivores with slow reproductive rates, bulk food requirements, wide foraging ranges and high potential value are highly vulnerable to those changes. Their responses to environmental pressures and human-induced landscape changes are however, not well understood.  The purpose of this study was to generate essential data and information to support sustainable conservation and management of Maasai giraffes in the changing landscape of

Factors affecting habitat use by Masai Giraffe (Giraffa camelopardalis tippelskirchi L) in Athi-Kapiti Plains ecosystem, Kenya

Increased human settlement, land use changes, loss of migration corridors, habitat loss and fragmentation have affected habitat use by Masai giraffe in Athi-Kapiti plains ecosystem. The purpose of the study was to assess the factors affecting habitat use by Masai giraffe (Giraffa camelopardalis tippelskirchi) in the Athi-Kapiti plains ecosystem and to generate information for giraffe sustainable conservation and management. The specific objectives of the study were to assess past and present giraffe population, assess the relative abundance of giraffe food

"All About Giraffes"

The information I presented highlighted the work of Giraffe Conservation Foundation in the field, especially focusing on the Niger giraffe project…as well as a range of current ex situ initiatives designed to provide a better understanding of giraffe biology. To try and cover all bases I attempt to ‘marry together’ the work being done in the wild world with that undertaken in captivity, thus giving my audience of around 50 zoo keepers, students and those with a general interest in

Does illegal hunting skew Serengeti wildlife sex ratios?

In this article we show that the population of Serengeti Masai giraffes Giraffa camelopardalis tippelskirchi is extremely female biased, particularly among newborns. Our results suggest that this might be a response to heavy illegal hunting and the continuous disturbance such activities cause on giraffes, as sex ratios were more female skewed in all age groups in areas with high risk of illegal hunting. Giraffes were also more vigilant and fled at longer distances in such areas. Such female skewed sex ratios have

Collared!

North-western Namibia is a spectacular land of desert mountains, gorges, plains, and ephemeral rivers, and a land of stark beauty and seemingly inhospitable wilderness. It was here that the wildlife vet and capture expert Michael D. Kock came to help attach satellite collars to desert-dwelling elephants and giraffes so that their movements in their vast range could be tracked. Collaring the animals was the easy part. Getting permission to do so, and then finding them, were rather more challenging.

The social organization of giraffes in Niger

The social organization of the last population of giraffes (Giraffa camelopardalis) in West Africa was studied between October 1996 and December 1997. Population size increased from 51 to 63 individuals during the study period. Groups were larger during the rainy season (mean group size 9.4) than during the dry season (mean group size 6; U=4131; P³0.01). Giraffes did not show strong preferential associations. Group types observed were similar to those expected on the assumption that associations are independent of sex

An overview of giraffe giraffa camelopardalis taxonomy, distribution and conservation status, with a Namibian comparative and focus on the Kunene Region.

Limited knowledge of the giraffe’s taxonomy, distribution and conservation status currently exists at the species and subspecies level. This lack of understanding has compounded the species long-term conservation Africa-wide, including in Namibia where waves have been made regarding the species potential conservation down listing based on little, if any, scientific evidence. This study provides the first concise overview of the Namibian giraffe in respect to its taxonomy, conservation status, population numbers and historical distribution, and in context of the entire

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 crisis in that their numbers have decreased by almost 40 percent in the last 30 years, and yet, this decline has received little media attention.

Conservation monitoring: estimating mammal densities in woodland habitats

Conservation and ecological monitoring programmes often estimate animal densities over time, but in wooded and forested areas practical techniques are still poorly developed. Here I have examined five simple methods of deriving densities of large and medium-sized mammals using line transects driven through miombo woodland habitat in Africa. These methods calculated area by dividing the number of individuals seen by (i) an average of each species’ sighting distances, (ii) a fixed 200 m belt width, (iii) the area visible from
