Spatial simulation of pasture growth and utilisation by herbivores is being
developed as an aid to rational drought management in Queensland. A
geographic information system (GIS) of climatic variables, soil attributes,
pasture type, tree cover and stock numbers on a 5x5 km grid facilitates the
running of a pasture simulation model (GRASP) on a state -wide basis.
Interaction of stock density and pasture growth with the best climatic
scenarios for the next 90 days will produce estimates of current and future
pasture utilisation. Where utilisation is excessive maps showing land
condition alerts will be issued.
