A yield model for Cordia alliodora plantations in Ecuador
A yield model for Cordia alliodora plantations in the Pacific lowlands of Ecuador is described. The data base comprises 73 permanent sample plots and 479 temporary inventory plots on 1600 ha of plantation. The oldest stands were 19 years in 1997. Site index curves are developed to predict Lorey's height from age. The Schumacher equation is used with a polymorphic form. Volume is calculated from a logarithmic function of stocking and Lorey's height; functions for volume to 10 cm top diameter overbark and 20 cm top diameter underbark are given. Mean annual volume increment curves are presented for a range of site index values and stockings. Maximum MAIV to 10 cm overbark is around 16 m³ ha⁻¹ y⁻¹ at age 3, and 9 m³ ha⁻¹ y⁻¹ at age 11 for 20 cm underbark volume for typical site index of 24 m (age 10) and 300 trees ha⁻¹.
