Curvas anamórficas de índice de sitio para plantaciones de Pinus caribaea Morelet var. caribaea Barret y Golfari de la empresa forestal integral macurije (EFI) en la provincia de Pinar del Río, Cuba

in this work we selected the best model for obtaining anamorphic site index curves for pinus caribaea morelet var. caribaea barret and golfari stands belonging to the macurije integral forest company, located in the municipalities of guane and mantua in the province of pinar del rio, cuba. we used data recorded from 14 permanent plots established in the year 2006 with four consecutive measurements taken throughout the different basic forest production units, 256 temporary lots randomly distributed throughout the enterprise area and the forest inventory carried out by the company in 2002-2003. the anamorphic-based site index curve system was constructed using the nested regression method applied by bailey and clutter (1976) and described by alder (1980) as a method of hierarchical regression with a common slope estimator. the model fitted dominant height (ho)-age data, and six site indices were derived for 13, 16, 19, 22, 25 and 28 m at 35 years old. in addition, the equation for determining the site index was obtained.
