Jon is a plant ecologist working in the field of sustainable weed management and the design of cropping systems and landscapes to reconcile crop production with biodiversity and Ecosystem Services. He has a particular interest in the application of functional ecology to understanding the assembly of weed communities under contrasting management scenarios. Jon’s primary areas of expertise are in the autecology and community dynamics of arable weed communities, requiring competency in botany, multivariate statistics, agronomy, process based modelling and field experimentation. Jon has also pioneered the approach of combining species level population dynamics models with databases of plant traits to predict functional shifts in weed floras in a response to a change in management or environment.
