Les éléphants occupaient jadis un vaste territoire continu à travers toute l’Afrique de l’Ouest,?s’étendant des forêts côtières au Sahara.
Elephants once occupied a largely continuous range across West Africa, from the coastal forests to the Sahara.
Numbers of elephants have declined in Africa and Asia over the past 30 years while numbers of humans have increased, both substantially. Friction between these two keystone species is reaching levels which are worryingly high from an ecological as well as
As human encroachment into elephant rangelands restricts elephant movements, it is increasingly critical to identify elephant range needs, and the effects of barriers to movements for the purpose of planning conservation areas.
Few data exist on the ranging behaviour of forest elephants.
A geographic information system (GIS) was used to analyse field data on the abundance of elephant dung-piles.
Many African elephant populations have declined over the last two decades (Douglas-Hamilton. 1987). In most census zones, as the number of elephants decreases, the number of dead elephants increases.
The taxonomy of West African elephants is reviewed along with their distribution during 1976-1984 study done in a biogeographical context.
Results from a large scale aerial survey of large mammals in the Tsavo ecosystems in February are compared to earlier surveys.
The objective of this report is to provide information on elephant numbers, distribution and trends, and factors affecting these, which will be helpful to countries in reviewing and setting quotas under the CITES Ivory Export Quota agreement.
