The Fodder Flow Planner is a simple tool designed to aid rangeland users in southern African drylands to annually set realistic livestock and game stocking rates. In the App the user specifies the size of the land, estimated herbaceous biomass available at the end of the rainy season and the current numbers of livestock and game using the land. The output is a graph forecasting the fodder depletion rate over the dry season. A predicted fodder shortfall before the end of the dry season serves as an early warning that the fodder demand by the current animal numbers are likely to exceed the fodder supply, while a good overlap of forecasted fodder availability and the expected start of the new growing season indicates sufficient or surplus fodder supply. The tool is specifically designed for grazing animals, but also calculates the browsing component’s stock rate.
