Growth and production of a young planting of Pinus caribaea var. hondurensis in the Western Amazon

Abstract

In addition to the need to understand the growth and production of forest plantations in the northern region of the country, where there is strong pressure on native forests and growing market demand for wood, monitoring forest stands is fundamental in decision making, providing information necessary for its management. This research aimed to evaluate the growth and production of Pinus caribaea var. hondurensis trees in Vilhena, state of Rondônia, Brazil. The data were obtained from a 5-year-old plantation using the Complete Stem Analysis – ANATRO technique. The observed and estimated dendrometric variables were used in the construction of growth and production curves, as well as for the average annual increment and current annual increment curves. It was observed, for the variable Diameter at Breast Height – DAP, Technical Cutting Age at 5 years of age at planting, with an average annual increase of 2.4 cm, and for the variables transversal area, total height and total volume with bark, an increase of 0.0024 m2, 1.7 m and 0.0588 m3, respectively. At the age of 5 years, 93% of the remaining trees remain, with a volumetric stock of 58.1 m3 ha-1 and a basal area of 12 m2 ha-1.
