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… 

Termite Mounds as Nutrient-Rich Food Patches for Elephants1

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.

Termite Mounds as Nutrient–Rich Food Patches for Elephants

This study compared elephant use of woody vegetation on termite mounds with surrounding woodlands in western Zimbabwe. Twelve sites consisting of paired plots on termite mounds and in woodlands were

Nutritional status of forage plants and their use by elephant in Waza national park, Cameroon

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.

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, elephants

Interactions between woody plants, elephants and other browsers in the Chobe Riverfront, Botswana

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.

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.

African Elephants Loxodonta africana Amplify Browse Heterogeneity in African Savanna

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.

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 are

Observations of tree growth, woodland structure and elephant damage on Colophospermum mopane in Luangwa Valley, Zambia

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.

Vegetation composition and elephant damage in the Sengwa Wildlife Research Area, Rhodesia

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.

PALATABILITY OF WOODY PLANTS TO BROWSING RUMINANTS IN A SOUTH AFRICAN SAVANNA

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.

Foliage acceptability to browsing ruminants in relation to seasonal changes in the leaf chemistry of woody plants in a South African savanna

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.

Utilization by elephants of the Brachystegia woodlands of the Kasungu National Park, Malawi

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.

Resource availability hypothesis of plant antiherbivore defence tested in a South African savanna ecosystem

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.

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.
