Description :
The case study was established in Alfisols and slopes ranging from 30 to 60% in Guanacaste, Costa Rica, and compares secondary forests with mature teak plantations and young teak plantations under different management regimes. The common myth of high soil erosion rates in teak plantations is refuted. Moderate or low erosion rates are usually found in teak plantations. Prescribed fires in some plantations have probably caused the false myth. It is concluded that poor forest management (prescribed fires, machinery, extremely steep slopes, previous land use, etc.) rather than the nature of the teak itself causes the high rates of erosion.
