MARTINEZ-ALBAN, Víctor; SOLIS-VARGAS, Adrián  and  CAMACHO-HERRERA, Rolando. Three distances of timber boundaries of Araucaria hunsteinii K. Schum. in Turrialba, Costa Rica. Kurú [online]. 2021, vol.18, n.43, pp.1-8. ISSN 2215-2504.  http://dx.doi.org/10.18845/rfmk.v19i43.5803.

Three sites with timber boundaries with Araucaria hunsteinii were sampled, each of which presented a different distance. Dasometric variables such as diameter at breast height, commercial height and total height were measured, to which an analysis of variance and a differentiation of the means using a Tukey test were applied. It was obtained that the diametric growth did not present significant differences with a general average of 57.7 cm, not so in the total height, where the highest total height reached was 28.34 m. The volume data was extrapolated to 1 km line at each planting distance, in order to obtain an approximate volume performance, it got a maximum of 782.07 m3 km-1 in total volume was obtained with 412.37 m3 km-1 of commercial volume for the smallest distance.

Keywords : Araucaria hunsteinii; yield; AFS; timber boundaries.
