Los Andes sudamericanos son un conjunto de montañas, generan una diversidad de climas. Eucalyptus globulus ha sido instalado en muchas laderas de los Andes norperuanos a elevadas altitudes (como por ejemplo en Cajamarca - Perú), desconociéndose su crecimiento y viabilidad productiva. En el presente estudio se establecieron los siguientes objetivos: i) elaborar curvas de Índice de Sitio para masas de Eucalyptus globulus situadas en los Andes peruanos sobre los 3.000 metros de altitud, ii) analizar la relación entre variables ambientales y el Índice de Sitio y iii) evaluar el efecto potencial del frío en el crecimiento de estas masas en comparación con las de otras regiones. El Índice de Sitio (IS) fue estimado usando tres modelos base de crecimiento (Bertalanffy-Richards, Hossfeld y Korf) y dos métodos de derivación (Diferencias Algebraicas – ADA y Diferencias Algebraicas Gen...

Forest plantations can be established in order to restore degraded areas. Acoustic tomography, which is of increasing importance in forest management, was used in the present study to obtain information for managing plantations of Cedrelinga cateniformis Ducke in the Peruvian Amazon. The species is valuable in the timber sector of Peru, but the core wood tends to deteriorate and develop cavities. The main objective of the study was to model wood deterioration in Cedrelinga cateniformis Ducke using the data obtained through acoustic tomography. Eight plantations of varying ages were analyzed using acoustic tomography in order to obtain indicators of wood deterioration. Biometric, climatic, and edaphic data (explanatory variables) were also measured in each plantation. The indicator variables and explanatory variables were compared and evaluated using correlation and principal component an...

This study addressed multi-product optimization in Cedrelinga cateniformis plantations in the Peruvian Amazon, aiming to maximize volumetric yields of logs and sawn lumber. Data from seven plantations of different ages and types, established on degraded land, were analyzed by using ten stem profile models to predict taper and optimize wood use. In addition, the structure of each plantation was evaluated using diameter distributions and height–diameter ratios; log and sawn timber production was optimized using SigmaE 2.0 software. The Garay model proved most effective, providing high predictive accuracy (adjusted R2 values up to 0.963) and biological realism. Marked differences in volumetric yield were observed between plantations: older and more widely spaced plantations produced higher timber volumes. Logs of optimal length (1.83–3.05 m) and larger dimension wood (e.g., 25.40 × 5.0...
