Aboveground biomass of Tectona grandis plantations in Costa Rica

Perez Cordero L. D., . and Kanninen M., . Aboveground biomass of Tectona grandis plantations in Costa Rica. pp. 199-213. ISSN 0128-1283

There are few studies on biomass distribution for Tectona grandis plantations in Costa Rica. This paper reports the distribution of total aboveground biomass ofT. grandis and its relationship with diameter at breast height (dbh) age and stand density in plantations across Costa Rica. Foliage branch stem and total aboveground biomass were highly correlated both with dbh (r 0.91) and with age (r 0.85). Foliage dry biomass represented between 1 and 6 of the total tree dry biomass while 5 to 30 corresponded to branches and 70 to 90 to stem dry weight. Per hectare aboveground biomass tended to increase with increasing age class (young intermediate and mature). Foliage dry biomass varied between 3 and 9 Mg ha1 branch dry biomass between 11 and 54 Mg ha1 stem dry biomass between 70 and 221 Mg ha1 and total aboveground dry biomass between 84 and 284 Mg ha1 . Significant relations between crown diameter and aboveground biomass with dbh age and stand density useful for the management of stand competition are the main results of this study.

Abstract

There are few studies on biomass distribution for Tectona grandis plantations in Costa Rica. This paper reports the distribution of total aboveground biomass ofT. grandis and its relationship with diameter at breast height (dbh) age and stand density in plantations across Costa Rica. Foliage branch stem and total aboveground biomass were highly correlated both with dbh (r 0.91) and with age (r 0.85). Foliage dry biomass represented between 1 and 6 of the total tree dry biomass while 5 to 30 corresponded to branches and 70 to 90 to stem dry weight. Per hectare aboveground biomass tended to increase with increasing age class (young intermediate and mature). Foliage dry biomass varied between 3 and 9 Mg ha1 branch dry biomass between 11 and 54 Mg ha1 stem dry biomass between 70 and 221 Mg ha1 and total aboveground dry biomass between 84 and 284 Mg ha1 . Significant relations between crown diameter and aboveground biomass with dbh age and stand density useful for the management of stand competition are the main results of this study.
