This application was developed by AgResearch scientists Dr Graeme Bourdôt, Dr Shona Lamoureaux, Dr Alasdair Noble, Yiwei Chen and AgResearch summer scholar Carolyn Song.


This application is intended to visualise a range of grubbing strategies for the management of nassella tussock on a block of land. To run the application, information is needed on the number of nassella tussock plants present and the effectiveness and timing of grubbing. The application has the functionality to show how adjacent blocks of land affect each other.


This application was funded by AgResearch through the Strategic Science Investment Fund (MBIE) project, Pasture Weed Ecology and Management, and was developed in consultation with Environment Canterbury biosecurity staff.
