Heterogeneity in African savanna elephant distributions and their impacts on trees in Kruger National Park, South Africa

Joel O. Abraham et al.

Summary: The study found differences in the distribution of bull elephants and mixed herds in Kruger National Park, with bull elephants preferring sparsely treed basaltic sites near waterholes, while mixed herds tended to aggregate around permanent rivers. Surprisingly, the distribution of elephant impacts was largely unrelated to the distribution of elephants themselves, instead concentrating in densely treed areas and particularly on basaltic soils.

Woody encroachment happens via intensification, not extensification, of species ranges in an African savanna

Yong Zhou et al.

Summary: The study in Kruger National Park found that woody encroachment is widespread and highly variable, resulting in an increase in the number of common woody species and stem density. While local management can influence woody encroachment to some extent, it is limited by drivers beyond local control. Regular field sampling coupled with targeted fire management is recommended for more accurate monitoring of encroachment intensification.
