| This project investigates the effects of cattle grazing on the distribution of nitrogen in a semi-arid tropical savanna and how this relates to landscape function.
Plant and soil N characteristics are analysed in relation to grazing pressure, topographic position and season. The general condition of savanna exposed to grazing will be assessed using Landscape Function Analysis and compared to sites where large grazing animals have been excluded for the past 15 years.
The key research questions are:
- What is the spatial distribution and dynamics of nitrogen within this semi-arid savanna?
- How are nitrogen distribution and dynamics affected by grazing and how do they relate to landscape function?
Results will increase our understanding of nutrient
dynamics in trees and grasses within such savanna landscapes,
and this can contribute to the future management of
grazing in savannas.
