The calculated production level of the forest plantation ( teak ) under optimal conditions amounts to 229 t / ha or 381 m3 / ha per 20 years . ... Stem - growth periodicity of trees in a tropical wet forest of Costa Rica .

Relation of climate to growth periodicity in tropical trees . In P.B. Tomlinson y M.H. Zimmerman ... Comparative phenological studies of trees in tropical wet and dry forests in the lowlands of Costa Rica . J. Ecol . 62 : 881-919 .

The purpose was to evaluate height and diameter growth during a 5 year period . ... in Turrialba , Costa Rica , established experimental plantations of some valuable forest tree species in the " Premon- tane Wet Forest " life zone of ...

Introduction Interspecific variations in tree growth rates play a pivotal role in the determination of the structure ... The present study was carried out in a lowland rain forest of northeastern Costa Rica , under management for timber ...

However , in the tropical wet zones little is known about the water - soil - plant interactions that would permit the planning ... The area involved has a total of 25 million hectares , five times the total land surface of Costa Rica .

These tree root / fungus symbioses function as " nutrient traps " and are assumed to be assumed to be indispensable for the securing of the closed nutrient cycle of moist tropical forests ( Lamprecht , 1989 ) .

During this early period , living fences may need protection , particu- larly from hungry animals . As the trees and shrubs grow , they must be pruned , usually on an annual basis . Otherwise , they may take up too much space or cast ...
