The relationship between elephant damage and leaf nutrient concentration across tree species was investigated in a semi-arid savanna in western Zimbabwe with the purpose of investigating possible nutritional factors influencing elephant feeding preferences in Kalahari sand woodlands. The presence of elephant damage was recorded in all trees above 1 m in height, and leaf samples were collected from all tree species encountered in 12 vegetation plots during the late dry season. Elephant damage… Expand
Termite Mounds as Nutrient-Rich Food Patches for Elephants1
TLDR
Trees growing on termite mounds had higher concentrations of all nutrients except sodium and crude protein, and were subjected to more intense feeding by elephants than trees from the surrounding vegetation matrix. Expand
A functional hypothesis of the threat of local extirpation of woody plant species by elephant in Africa
TLDR
Mitigation of the threat of local extirpation should concentrate on configuration of boundaries, water provision, simulated predation, minimum reserve size, and not pursue non-definable notions of elephant carrying capacity. Expand
The impact of African elephants on Acacia tortilis woodland in northern Gonarezhou National Park, Zimbabwe
We investigated the impact of African elephants (Loxodonta africana) on the structure and composition of Acacia tortilis woodland in northern Gonarezhou National Park, southeast Zimbabwe. A. tortilisExpand
Nutritional status of forage plants and their use by elephant in Waza national park, Cameroon
TLDR
Because of the generally poor nutritional value of natural fodder, the elephants in Waza National Park frequently break out to feed on nutritive richer agricultural crops. Expand
Elephant herbivory in Majete Wildlife Reserve, Malawi
Elephants have a major influence on vegetation structure, composition and ecosystem processes, and are primary agents of habitat change in Africa. At moderate-to-high population densities, elephantsExpand
Interactions between woody plants, elephants and other browsers in the Chobe Riverfront, Botswana
TLDR
Results in this thesis do not justify manipulation of elephant population and distribution as a means to increase populations of the other animal species investigated, but it seems that elephants may act to facilitate browsing by other investigated animal species. Expand
Patterns of elephant impact on woody plants in the Hluhluwe-Imfolozi park, Kwazulu-Natal, South Africa
This study identifies patterns of elephant Loxodonta africana africana impacts upon tree species and woody plant communities in Hluhluwe-Imfolozi Park, a South African savannahs/woodlands area.Expand
African Elephants Loxodonta africana Amplify Browse Heterogeneity in African Savanna
TLDR
The results provide the insight that elephants facilitate the redistribution and availability of browse and improve the quality, which may positively affect small browsing herbivores. Expand
Soil fertility on granite and sedimentary soils is associated with seasonal differences in foraging by elephants
Background and aimsIt is generally assumed that very large herbivores, such as elephants, make foraging decisions at large spatial scales, but the extent to which seasonal foraging decisions areExpand
Elephant herbivory, frost damage and topkill in Kalahari sand woodland savanna trees
TLDR
Frost is an important and generally overlooked disturbance agent in southern African woodlands, where it may play a key role in association with other disturbance factors – such as elephant herbivory – that reduce woodland canopy cover. Expand

Observations of tree growth, woodland structure and elephant damage on Colophospermum mopane in Luangwa Valley, Zambia
TLDR
Soils that promote coppicing of C. mopane yield less stable woodlands when associated with elephants than soils promoting woodlands with large bolus, non-coppicing trees. Expand
Vegetation composition and elephant damage in the Sengwa Wildlife Research Area, Rhodesia
TLDR
It appears that elephant damage is not related to the chemical constituents analysed in the vegetation and in the soil, except for a low positive correlation with sodium in the mud, and there was little relationship between densities and elephant damage. Expand
PALATABILITY OF WOODY PLANTS TO BROWSING RUMINANTS IN A SOUTH AFRICAN SAVANNA
TLDR
A palatability classification of woody species is proposed, considering features of leaf retention (deciduous vs. evergreen) and spinescence, as well as seasonal variations in acceptability. Expand
Foliage acceptability to browsing ruminants in relation to seasonal changes in the leaf chemistry of woody plants in a South African savanna
TLDR
The high acceptability of certain otherwise unpalatable species during the new leaf phenophase was related to elevation of protein levels relative to condensed tannin contents. Expand
Utilization by elephants of the Brachystegia woodlands of the Kasungu National Park, Malawi
TLDR
The pushing over and uprooting of trees by elephants appear to be part of a feeding strategy which improves the availability of food for elephants during the dry season, and the species composition of Brachystegia woodlands is hardly affected by elephant use. Expand
Food selection by elephants in the ‘miombo’ biome, in relation to leaf chemistry
Abstract Mature foliage selected by elephants in Brachystegial Julbernardia woodlands was characterized by high mineral and sugar content. Tree species avoided were high in total phenols andExpand
Patterns of elephant damage to vegetation in northern Botswana
TLDR
Elephant-induced damage to trees and shrubs that dominated the vegetation biomass in 33 sites suggested that elephants had a more or less random impact on the vegetation throughout their distribution range although the total biomass removal was low. Expand
Resource availability hypothesis of plant antiherbivore defence tested in a South African savanna ecosystem
TLDR
Positive correlations between the inherent growth rates of nine South African woody species and kudu and impala preferences for their mature leaves are found and the resource availability hypothesis of plant antiherbivore defence could explain why large African herbivores feed less on woody vegetation of dystrophic savanna-woodlands than on wooded vegetation of eutrophic savannas.

GEOPHAGY IN THE AFRICAN ELEPHANT IN RELATION TO AVAILABILITY OF DIETARY SODIUM
TLDR
Investigating the use of mineral licks by African elephants during the dry season in a Kalahari-sand habitat in Hwange National Park, Zimbabwe found the following consistent with the Na+-supplementation hypothesis: unlike other minerals, Na+ in woody plants and natural water supplies may be inadequate to meet the minimum requirements of elephants duringThe dry season.
