Dr Bradley Law is a Principal Research Scientist in the Forest Science Unit, NSW DPI. Brad's team undertakes scientific research to underpin ecologically sustainable forest management practices, which includes studies of the impact of forest disturbances (logging, fire), the effectiveness of forest management prescriptions and the ecology of threatened species plus the biodiversity benefits of native tree plantings on farms.

Brad has a background in zoology and ecology. His personal research program currently has a heavy focus on koalas in forests, especially using acoustics as a tool for survey and monitoring. He also has a long term interest in bat ecology, probably the most species diverse group of forest mammals in NSW. An emphasis has been placed on long-term ecological studies, because of the length of life cycles in forest ecosystems. Recent research also includes studies on Eastern Pygmy Possums and Hastings River Mouse. Other studies have investigated the effect of logging on canopy nectar production in eucalypts. He is also interested in urban ecology and has co-supervised a number of postgraduate students in recent years investigating a range of ecological topics. Brad is co-editor of Australia's oldest zoological journal: Australian Zoologist and has published more than 130 peer-reviewed papers.

Current projects

  • koala ecology in forestry landscapes: habitat modelling, occupancy on state and private land, estimating koala density and GPS tracking to assess current prescriptions
  • changes in bat survival in relation to climatic extremes and logging at a long-term logging experiment
  • long-term changes in biodiversity in large scale commercial eucalypt plantations established on farms
  • developing methods of monitoring for wildlife
  • monitoring of hastings river mouse and its response to harvesting
