Stand structure and commercial volume of secondary forests in Paraguay and Costa Rica: implications for management options
Stand development of secondary forests (established after clearing for agriculture) was studied and compared with primary forest in Paraguay and Costa Rica. focusing on commercial species. Accumulation of bale volume was markedly more rapid in the wetter (Costa Rica) than the drier site (Paraguay). However, the more fertile soils in Costa Rica compared to Paraguay may contribute to a faster development of this stand parameter. The proportion of commercial species contributed by bole volume increased with successional age. In young secondary forests, commercial species at sapling stage were mainly represented by sprout-established individuals, while the proportion of vegetative regeneration declined in more advanced successive stages. Management options and major legal shortcomings are discussed.
