The taxonomy of West African elephants is reviewed along with their distribution during 1976-1984 study done in a biogeographical context.
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.
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.
Attempts to determine if vegetation types of Africa are adequately covered in the existing protected areas system.
Refutes the hypothesis that the ivory trade does not pose an immediate crisis for the elephant, but that the increase in human population causing the restriction in elephant range is responsible for loss of elephants and is at the root of current populati
The paper relates ivory price to an index of inflation in order to explore the basis of a link between the rate of the killing of elephants and the rise in price of ivory greater than that of inflation.
Describes aerial census of Ruaha National Park and adjacent areas including Rungwa and Kisigo Game Reserves.
Elephants have always posed problems to authorities, either as crop raiders, major agents of habitat change or as a potentially valuable natural resource.
