David Chapman

David’s research career has centred on pasture ecology and pasture production; grazing management; plant-animal interactions in grazing systems; bio-economic evaluation of genetic gain in pasture plant breeding; and grazing systems development including managing the environmental impacts of pasture-based livestock production.

The main research programmes that David currently leads aim to: develop a multi-trait, economically-based evaluation index for ranking forages on their relative profitability (and, ultimately, environmental impact) in dairy systems as a basis for farmer decision-making and increasing plant genetic gain; identify key plant-environment interactions governing the productive life of pastures and possible interventions for increasing pasture longevity; and develop farm systems the support increased productivity and profit while reducing nutrient losses to the environment.

David currently chairs the industry Steering and Technical Working Groups responsible for the strategic and technical development of the DairyNZ Forage Value Index; the seed industry Endophyte Technical Committee responsible for reviewing and collating the science regarding endophyte efficacy in pastures; and the Science Advisory Panel of the Pastoral Genomics consortium which is developing genomic selection indices for key traits in perennial ryegrass and white clover.
