Biographical details

Dr Ingram obtained his B. Agr. Sc from the University of Melbourne before completing a Ph.D. from the University of Western Australia in native grass ecology and the potential impacts of grazing on these grasses in the Pilbara region.
After completing my Ph.D he took a post-doctoral position at the University of Wyoming (Wyoming, USA) / USDA Agricultural Research service where he worked from 2001 – 2008 in a number of different areas including; a) Determining the impacts of coal strip-mining on soil quality, microbiology, soil C sequestration and physical structure; b) the positive impact that inter-seeding lucerne can play in improving soil nitrogen and subsequently soil C and N. In addition, what role does this additional nitrogen play in contributing to trace gas (nitrous oxide and methane) production; c) The impact of long-term grazing on plant and soil parameters in mixed-grass prairie ecosystems in Wyoming.

In 2008 he moved to Idaho State University where I worked on;
a) the impact of fire on soil erosion in sagebrush steppe ecosystems
b) Investigating hydraulic infiltration in a sagebrush steppe ecosystem.

He took up his current position in Sustainable Grassland Management in July 2009.



Research interests

Dr Ingram is interested in not only understanding grassland ecosystems but also how we can better manage them in a sustainable manner. As a result it is necessary to understand the many factors, and the interactions between these factors, that make up a grassland system: soil-roots/plants-animals-atmosphere. Consequently much of his research career has involved studies that have often been very much broadly based (and often landscape focused) rather than finely detailed and highly focused research. His current position involves a very strong focus in the Monaro region of southern NSW as well as the alpine grasslands present on the Snowy Mountains
. Currently he is involved with research that includes:

  • Determining the impact that lucerne and improved pastures have on soil nitrogen, carbon, soil structure and soil water in the Monaro
  • The impact of grazing & fire on alpine meadows and woodlands
  • Using a variety of technologies to determine patterns of grazing and animal behavior (cattle & sheep) in Monaro grasslands as well in central tablelands of NSW
  • Dieback in the eucalyptus species, E. viminalis (manna or ribbon gum)
  • The use of fertilizers and legumes on soil fertility
  • Management and ecology of the weed, African Lovegrass
