Identification of the first cases of Peste des Petits Ruminants and Rift Valley Fever viruses in Koure’s Giraffa camelopardalis peralta of Niger Republic

PPR and RVF are two known diseases in domestic ruminants. An annual vaccination Campaign is being done on the first while in 2016 an epidemic outbreak affected both animals and humans in Niger on the second. The aim of this investigation is to assess the circulation of these two diseases in another wild ruminant, specifically Giraffa camelopardalis peralta. Having an average annual increase rate of 10% together with conservation, the giraffe population increases from 56 individuals in 1996 to 607

The last African white giraffes live in farmers’ fields

The giraffe population (Giraffa camelopardalis) in Niger is the last representative of the peralta sub-species which lived throughout West Africa at the beginning of the twentieth century. Protected since the 1970s, giraffes cohabit with humans in cultivated landscapes. This may not have appeared to pose many problems in the past, but the relationship between farmers and giraffes has deteriorated with the expansion of cultivated land and that of the giraffe population, with reported cases of giraffes damaging crops. A survey

Giraffe south of the Niger-Benue river system

Although giraffes have been seen occasionally south of the Niger river, there is no evidence that permanent populations occur in this area) and presumably the giraffes either die or return to the northern side. The southern habitats may be unsuitable for two reasons. First, human harassment and habitat modification may prevent the establishment of viable “southern herds”. Secondly, there may be an absence or inadequacy of particular food plants or some other environmental requirement. These speculations emphasize the necessity of

Giraffes (Giraffa camelopardalis peralta) of Niger

Thirty years ago giraffes were found all over the Sudano-Sahelian area, from Mauritania to Chad. Over the last 20 years, due to loss of habitat and poaching, giraffe populations have decreased. In Niger large herds were present in the Tanout area, between Agadez and Zinder, but they disappeared because of recurring drought. During the eighties, giraffes were present in the Ayorou area, but suddenly disappeared because of poaching along the Malian border and the 1984 drought. Today the sub-species Giraffa

The feeding behaviour of giraffe in Niger

The remaining West African giraffes (Giraffa camelopardalis) are found in Niger (62 individuals in January 1998). Their feeding behaviour was studied by direct observation during two periods of 6 and 12 mo. The giraffe’s diet is diverse: at least 45 plant species were eaten, depending on spatial arrangement and a given plant’s stage of growth. Time spent browsing during the dry season was twice that devoted to browsing during the rainy season (46 and 23 % respectively). Time spent feeding

Female tannin avoidance: a possible explanation for habitat and dietary segregation of giraffes (Giraffa camelopardalis peralta) in Niger

Niger is host to the last free‐roaming herd of G.c. peralta (Giraffa camelopardalis peralta). We examined the foraging preferences of these giraffe in their dry‐season habitats, with the goal of preserving the herd in the regions that they currently inhabit. The current dry‐season habitat comprises two distinct vegetation zones. In both of these zones the giraffe must exist alongside the people of this region. The giraffes exhibit a sexual segregation in their dry‐season habitat selection and forage choices. The females

Overview of the ecology of the Niger giraffe

The giraffe of Niger are the last in all West Africa. It is threatened. They are both genetically and ecologically distinct from other giraffe and are therefore an important biodiversity remnant. Although baseline research has been limited, it does provide snapshots of what has happened to the population’s numbers and distribution over the past decade. Currently, the population is increasing and genetically healthy, however, its range has been significantly reduced and habitat loss and fragmentation continues to be a major

Seasonal movements of giraffes in Niger

The last population of giraffes in west Africa lives in Niger in an unprotected Sahelian region inhabited by farmers and herders. The spatial behaviour of each individual of the population (n = 63) was studied by direct observation during 15 mo. Two-thirds of the population were resident in the tiger bush in the rainy season and in the nearby area of Harikanassou, a sandy agricultural region, in the dry season. Rainy season and dry season home ranges were mutually exclusive

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
