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 and 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 on soil carbon and nitrogen in semi-arid Wyoming (collaborative prject with the Agicultural Research Service - US Dept of Agriculture.
  • The use of fertilizers and legumes on soil fertility
  • The impact of grazing & fire on alpine meadows and woodlands on biodiversity, soil C and fuelloads
  • 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
  • The impact of grazing intensity on cattle behaviour in semi-arid Colorado ((collaborative prject with the Agicultural Research Service - US Dept of Agriculture)
  • Understanding the causes of dieback in the eucalyptus species, E. viminalis (manna gum)
  • Management and ecology of the weed, African Lovegrass

Current projects

Weeds are estimated to cost pastoral systems in the vicinty of $1.4 billion dollars and can have major impacts on both on agricultural production as well environmentally. IN the Monaro region of southern NSW, the highly invasive grass weed, African Lovegrass, is having signficant effect on these ecosystems. In this project we are looking at ways to not only improve the detection of lovegrass but better understanding the drivers of its spread as well as investigating not only best managment practices but also landholder initiated control/managment options.

Soil C plays a crtical role in "soil health" however the effect of land managment, in particular grazing, is not well understood. While greenhouse studies often find grazing has a negative effect on a wide range of plant and soil process, we often don't observe the same effects in the field, under an actual grazing situation. This project will attempt to gain a better understanding of the effects on the ecophysiology of grazed grasses and, ultimately, on the extent that this plays in carbon sequestration in grassland systems.
