During the last two decades, the Costa Rican government has promoted the establishment of Tectona grandis plantations for sawn timber. However, there is a lack of knowledge on optimum spacing and on thinning regimes, in contrast to high expectations of final mean diameter at breast height (DBH) b...

Intensity and timing of the first thinning of Tectona grandis plantations in Costa Rica: results of a thinning trial
Linking forest management to timber industry requirements is fundamental. Connections of silvicultural activities with wood quality are often limited to size-related characteristics, such as minimum DBH. Restrictions set by international markets (e.g. minimum log dimensions, heartwood content and...

The aim of this study was to evaluate the heartwood, sapwood and bark content, and wood dry density of young and mature teak (Tectona grandis) trees. For this, 17 plantations were selected from 11 sites representing different climatic conditions and plantation densities (156 to 1600 trees ha-1, a...

Estimation of the commercial volume to diameters and variable heights for Tectona grandis L.F. in Costa Rica. Management practices for Tectona grandis have improved during the last decade. However, accurate volume equations are not available yet. The aim of this study was to test equations which ...

In total 60 plots of approximately 80 trees each (including missing trees) were measured, with ages between 1 and 26 years. The main objective of this study was to develop intensive management scenarios for B. quinata plantations in Costa Rica to ensure high yielding of timber wood. The scenarios...

There are few studies on biomass distribution for Tectona grandis plantations in Costa Rica. This paper reports the distribution of total aboveground biomass of T. grandis and its relationship with diameter at breast height (dbh), age and stand density in plantations across Costa Rica. Foliage, b...

The aim of this study was to develop equations which best predict individual-tree total volume and mercahntable volume for T. grandis in Costa Rica. A total of 112 trees with ages between 2 and 47 years and breast height diameter (dbh) between 2.4 and 58.7 cm were felled for stem analysis. Linear...
