Abstract The apparent increase in elephant Loxodonta africana numbers in northern Botswana is of concern because it may affect other species. We compared changes in population growth rates based on elephant numbers and densities over 1973–2004. Population estimates and survey details extracted from published and unpublished sources allowed us to calculate growth rates. From 1973 to 1993 growth rate was positive when based on elephant numbers but did not differ from zero when calculated for… 

An analysis of numerical trends in African elephant populations

The elephant debate deals largely with population size, how elephant numbers change over time, how they may affect vegetation, and how their populations should be managed. Trends in elephant numbers

Solutions for elephant Loxodonta africana crop raiding in northern Botswana: moving away from symptomatic approaches

Abstract Conflict between people and elephants in Africa is widespread yet many solutions target the symptoms, rather than the underlying causes, of this conflict. To manage this conflict better the

Aerial Survey Intensity as a Determinant of Estimates of African Elephant Population Sizes and Trends

Population estimates based on strip transect aerial surveys of large herbivores can aid management decisions If estimates are accurate and precise. Because sampling Intensities may Influence

African elephant in a cleft stick : choosing between starving or dying from thirst in arid savanna

Elephant population studies have become important especially because of the long standing perception that high elephant densities have negative impact on vegetation and other wildlife species. Thus,

RETRACTED: Population and Trophy Quality Trends of Three Gregarious Herbivores in an Insulated Semi-Arid Savanna Ecosystem (Cawston Ranch, Zimbabwe), 1997–2014

Long term monitoring of population estimates and trophy size trends is needed to ensure that trophy hunting is sustainable. We explored the influence of trophy hunting on population size and trophy

Elephants - a conservation overview

Loss of habitat is one of the most significant problems facing elephants worldwide, leading to clashes over resources between wildlife and humans where elephants receive the largest part of blame -

The numbers game in wildlife conservation: changeability and framing of large mammal numbers in Zimbabwe

Wildlife conservation in terrestrial ecosystems requires an understanding of processes influencing population sizes. Top-down and bottom-up processes are important in large herbivore population

Potential Impacts of Temperature Projections on Selected Large Herbivores in Savanna Ecosystem of Kenya

Due to global land surface warming, severe temperature events are expected to occur more frequently and more extremely causing changes in biodiversity and altering movement and survival of large

Determinants of protected area boundary crossings by savannah elephants, Loxodonta africana

When elephants leave primary protected areas (PPAs), such as national parks and game reserves, they may come into conflict with people residing on the adjoining land. In this study, I attempted to

The Return of the Giants: Ecological Effects of an Increasing Elephant Population

Investigating the interactions between the increasing elephant population and other ecosystem components and processes in northern Botswana confirms that the ecosystem is changing following the increase in elephant and ungulate populations, and developing towards a situation resembling that before the reduction of large herbivores.

Managing heterogeneity in elephant distribution: interactions between elephant population density and surface‐water availability

The cumulative interference of past and current elephant numbers with the conservation of bird diversity appears to be insignificant in northern Botswana.

Culling and the dynamics of the Kruger National Park African elephant population

South Africa's National Parks Board has opted to control African elephants (Loxodonta africana) through culling in the Kruger National Park (KNP). Killing elephants is highly controversial. The Board

Conservation science and elephant management in southern Africa

This approach avoids reducing numbers directly and addresses patterns of spatial use to reduce local impacts and limit regional numbers and emphasizes the cause of the elephant problem and focuses on a systemic rather than a symptomatic treatment.

It is shown how keystone processes can, in principle, be measured using the example of the wildebeest in the Serengeti ecosystem and how these relationships are relevant to applied aspects of conservation and pest management.
