Modeling growth and yield of loblolly pinestands under intensive management

Abstract: -The objective of this work was to develop and validate a prognosis system for volume yield and basal area of intensively managed loblolly pine (Pinus taeda) stands, using stand and diameter class models compatible in basal area estimates. The data used in the study were obtained from plantations located in northern Uruguay. For model validation without data loss, a three-phase validation scheme was applied: first, the equations were fitted without the validation database; then, model validation was carried ou… Show more

“…However, this has been traditionally developed for cattle production, and not for forestry, which poses limitations for characterizing potential forest productivity. For P. taeda, instead, zonification has not seemed to be effective and has not been applied in the past (Ferraz Filho et al 2015, Rachid-Casnati & Hirigoyen 2015. Main advantages in using augmented equations rely in the possibility to represent differences in site quality in a more descriptive way than with the localization strategy.…”

“…On the other hand, total basal area production is lower than in other regimes, concentrating growth on a few selected crop trees of the stand. This type of regime characterizes an intensive management scheme, which aims to remove any growth strains (in this case competition from other trees) on selected trees to produce high value logs (Ferraz Filho et al 2015, Fox 2000, Maestri 2003.…”
