To illustrate the first method, let's say we start with a productivity or harvest yield of 100,000 fruits per hectare. A 10% reduction in this is equal to 10,000 fruits. How many trees need to be taken out of production to save 10,000 fruits? This result can be calculated from the yield curves for the species. In the case of Myrciaria dubia (Figure 6), the answer is three 12 cm diameter trees, twenty 6 cm diameter trees, or a variety of other tree size-tree number combinations.
