ESPINOZA-DURAN, Juliana  y  MOYA, Roger. Logging and industrialization of two Gmelina arborea plantations with different degrees of slopes. Rev. Chapingo ser. cienc. for. ambient [online]. 2013, vol.19, n.2, pp.237-248. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2011.09.067.

The main objective of this study was to determine the logging and industrialization of two 15 years-old Gmelina arborea un-managed plantations with two different slopes: 30% and 60%. Trees had an average diameter at breast height (DBH) of 31.23 cm and a total height of 14.87 m. Three logs per tree were extracted. Only 22% of total standing volume in the plantation is usable as end product for market sale. The non-sawlog (waste) was 42.57 in standing tree (42.57%), to extract log from tree filled (14.43%), to saw in central block (26.27%) and commercial lumber (22.10%). The lumber recovery was 53.22% in extracting a central block from logs and final lumber recovery in commercial lumber was 45.88%.
