Semi-arid savannas are commonly described as having ecosystem types with strongly seasonal plant communities which, in their natural state, have a relatively continuous herbaceous layer and a discontinuous woody component. This herbaceous layer consists of grasses and forbs (wildflowers). Given that the grass component functions as the main source of food for grazers and domestic livestock, assessments of range conditions in semi-arid savannas are largely based on dominant palatable grass species. Consequently, forbs are poorly represented in definitions, range condition assessments, and ecological studies of savanna ecosystems. Furthermore, less attention has been given to forbs and grasses as separate functional entities which are floristically, morphologically, and physiologically distinct. Dr Helga van Coller – a professional development programme postdoctoral fellow, studies the ecology of herbaceous communities, particularly in nutrient hotspots in South African savannas. Her postgraduate research focused on the dynamics of forbs and grasses in eutrophic sodic areas in a typically dystrophic savanna. These areas are considered nutrient hotspots since their nutrient-rich vegetation is intensely utilised by herbivores. This research provided a better understanding of the ecosystem services and functions that forbs provide in these important biogeochemical hotspots. Her current postdoctoral research explores the herbaceous plant communities and nutrient cycling associated with another important source of nutrients in savannas, being the decomposition of the carcasses of megaherbivores. This research forms part of a larger research consortium aiming to answer the overarching question: How do megacarcasses influence terrestrial ecosystem processes? In her talk, Helga will share her knowledge on the various ways in which forbs are important, both floristically and ecologically, and reflect on the rationale of including this life form in conservation, management and research of savanna, and other ecosystems.
