CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

The objective was to evaluate the effect of the site in the productivity of 12 Calycophyllum spruceanum Benth. forest plantations (replications) in a total area of 5.72 has. Plantations were distributed into 3 blocks in the Aguaytía River, located in the Ucayali Region. Direct measurements were used to evaluate the current state of the plantations and their relationship with soil and climate factors in order to identify potential places for the establishment of successful plantations. Site Index (SI), was defined as the average of the total height in meters of the higher quintile. Site Index was highly correlated to basal area, and total bark volume. Noteworthy differences were found in the plots evaluated. This allows the generation of a classification based in the Site Index. This classification is consistent with the blocks and the altitude throughout the basin in most of the cases. Growth average in the best replication resulted in a volumetric increment of up to 13.349 m3ha-1year-1.
