In a simulation study utilizing rainfall, evaporation and mean temperature data for 28 stations, from the West Kimberley to Central Queensland, an average of 40 dry seasons were analysed for the periods when the legume would have been green, dry but unspoilt, and spoilt. A 'dry leaf' nutritional strategy is desirable where the dry seasons are reliably rainless. Even in regions with a high risk of rain, if green leaf is maintained for a considerable time in the dry season there is also a low risk of spoilage, and the use of non-deciduous legume species in these regions and elsewhere is discussed.
