ESTRUCTURA Y DINAMICA DE BOSQUES DEL TIPO FORESTAL SIEMPREVERDE EN UN SECTOR DE CHILOE INSULAR

A study on structural and dynamic cha racterization of the forest was carried out in an area of the evergreen forest type lo cated in the neighbourhoods of Chepu, in the Isla Grande de Chiloé. Four stands on undisturbed forests were selected and 54 x 72 m plots were established in each one of them. Data for drawing vertical profi les, for crown classification, stand tables, diameter distribution diagrams, understo rey composition and structure and for spatial distribution of the species using the Morisita Index, were collected. Fur thermore a soil analysis in each stand was performed with the purpose of studying its morphologic variation and some chemical characteristics related to soil dynamics. Results show that the sampled stands are floristically and structurally similar and that they grow on two soil condi tions. Structure of the forests are charac terized by the presence of emergent trees of Eucryphia cordifolia Cav. and nume rous specimens of Laurelia philippiana Losser. Amomyrtus luma (Mol.) Legr. et Kauss. is the most characteristics species of these stands due to its abundance and the frequency of "creeping" trees.
