Aspects of leaf litter dynamics in a semi-arid mallee woodland

I am looking at factors that influence leaf litter (and associated nutrient) distribution and decomposition in semi-arid Australia. My study aims to characterise functions and processes involved in litter dynamics with a particular focus in the Mallee Dune fields of Eastern Australia (Western New South Wales region). My studies cover fundamental litter dynamics including litter fall rates; surface litter distribution and movement; litter decomposition; and potential effects of nutrient transfer on plant growth, in response to various events and ecosystem processes.

The dynamics of nutrient-rich organic matter is critically important in many ecosystems, particularly those that are resource-limited, such as the arid and semi-arid regions of Australia. Decomposition of organic matter is an important component of the biogeochemical cycle as it controls soil nutrient availability which consequentially affects ecosystem productivity and vegetation composition.

My study site is at the Scotia Sanctuary in western NSW and adjacent grazing properties. Parts of this project are in collaboration with the Australian Wildlife Conservancy.

I am focusing on several factors that influence litter dynamics. In particular my study will consider:

  • Spatial and temporal variation in litter fall across two dominant vegetation communities.
  • The effects of vegetation and geomorphic variation on litter distribution
  • The relative effects of termites, microbes and fungi in the decomposition process using a comprehensive litter-bag study.
  • Litter decomposition rates of native plant species in the foraging pits of native vs. exotic animals.
  • The effects of fire on the spatial distribution of surface litter.
