Profile

I provide advice and practical skills in several projects involving the collection, sorting and identification of terrestrial invertebrates, and analysis of responses of invertebrate assemblages to silviculture and fire.


Expertise

  • Invertebrate parataxonomy
  • Insects of Western Australian forests and timber
  • Effects of fire and silviculture on invertebrate assemblages
  • Western Australian earthworms

Brief CV

  • B. Sc. (Hons.) University of Western Australia.
  • Technical Officer- Pine silviculture, nutrition and water relations 1987-1991.
  • Technical Officer- Forest entomology 1992-present. Design, management, completion and reporting of projects involving: monitoring of Jarrah leafminer populations; effects of fire on Jarrah leafminer; insect faunas of Jarrah, Marri and Bluegum canopies; and distribution of earthworm species in Porongurup and Swan Coastal Plain landscapes. Sample collection identification and advice on analysis and interpretation of fire history effects on invertebrate assemablages of the Walpole Wilderness area and London Block small grain fire mosaic. Sample collection identification and analysis of invertebrate assemblage responses to silviculture: the FORESTCHECK  forest monitoring project. Monitoring gumleaf skeletonizer populations using pheromone baited traps: field data collection and analysis development of a predictive model outbreak conditions.

Projects

  • Influence of fire history and landscape on ground invertebrate community composition: Serpentine and Helena River valleys; Walpole Fire Mosaic.
  • FORESTCHECK invertebrates: Monitoring the long-term effects of Jarrah forest silviculture on invertebrate community composition.
  • Invertebrate threats to forest health: monitoring gumleaf skeletonizer populations using pheromone baited moth traps. Monitoring, refinement of methodology, predictive model for outbreak conditions.
