Other claims from this paper (5)
- Observation Establishment of adult Acacia trees was not constant for any of the three species.
- Observation All three Acacia species showed significant spatial patchiness in tree establishment.
- Observation All three Acacia species showed larger-scale temporal variability in establishment patterns.
- Mechanism Spatial patchiness of Acacia establishment highlights the importance of landscape processes such as fire and herbivory.
- Mechanism Current tree cover in savannas is a product of ecological history rather than only current processes.
