Today we had two more student whiteboard presentations from Erik and Kevin. Erik presented on the influence of herbivores on vegetation structure within Kruger National Park. His study used exclosures and airborne remote sensing technology to observe changes in vegetation growth with and without the presence of large herbivores. The researchers observed a significant difference between the two treatments, with greater species diversity observed in areas that included herbivores, due to increased seed dispersal and soil nutrient levels.
Kevin presented on the Tribal Grazing Land Policy (TGLP) that was implemented by the Botswana government in the 1970's. His presentation covered differences in land degradation across three main study areas, with overgrazing significantly reducing the amount of grass and herbaceous cover surrounding watering points. Environmental variability from rainfall and soil erosion additionally influenced the amount of degradation experienced in each study area.
