However, these interventions lead to increased ranging and foraging pressure and can negatively impact important habitats and species. This study investigated the influence of artificial water provision on the foraging and movement paths of an African elephant population and modelled the impact of changing water availability on sensitive habitat types.Location Tembe Elephant Park (TEP), KwaZulu-Natal, South Africa.Methods We mapped and classified 414 km of elephant movement and foraging paths in a 300-km2 fenced protected area. The data were analysed to determine the relationship between path size, distribution and distance to water. We also used a logistic modelling approach to explore the predicted effects of removing artificial water points on path distribution.Results Elephant paths were unevenly distributed throughout the habitats of TEP and the most established and heavily used paths were found closest to water. We also discovered a number of elephant ‘rest areas’ along the paths, which were distinct clearings that tended to be close to water and in sand forest habitat. Our model predicted that the removal of artificial water points would reduce the area crossed by elephant paths by 79%, leading to an 89% reduction in the presence of elephant paths in sand forest.Main conclusions Our study provides further evidence that manipulating surface water availability can be a useful tool for managing large herbivore impacts on vegetation and acts as the basis for further research on the trade-offs between conservation objectives.

The Grevy's zebra population has experienced a significant decline in the past 40 years from approximately 15,000 individuals to around 2,000–5,000. For this trend to be reversed, local people that share the pasture-land with Grevy's zebra must be involved. This study sought to identify the beliefs and levels of importance ascribed to Grevy's zebra by local people. In-depth surveys conducted in the region indicated that males and those with fewer numbers of livestock viewed the Grevy's more favorably. In addition, most respondents identified few direct benefits of the zebra, but individuals from areas with minimal tourism perceived the Grevy's zebra as providing financial benefits (e.g., via safaris). Findings suggest that outreach to local communities is needed about the benefits of the species as well as its population decline.
