The Prosopis sp. individuals known as carob trees are key species in the development of dry forest and recovery of degraded areas in the northern coast of Peru. The evaluation of plantations, calculation of aboveground forest biomass (AFB) and carbon stock represent an important role in forest management and climate change mitigation. This study evaluates monitoring methodologies using multispectral and LiDAR images coupled to a UAV, to validate them and generate models to estimate carbon stocks. Seven species of Prosopis sp. were evaluated with the conventional methodology and significant differences were found between species for dasometric characteristics and vegetation indices, as well as in the comparison with the data obtained with LiDAR. Models were selected to determine BAF and the association between the aerial carbon obtained with the models constituted by LiDAR data and vegeta...

En el presente estudio se evaluaron las propiedades físicas - mecánicas y se realizó la caracterización anatómica de la madera de ulcumano (Retrophyllum rospigliosii), procedente de una plantación de 32 años de edad bajo un sistema agroforestal con café, en Villa Rica, Pasco. Se identificó su aptitud de uso y se analizó la variación de las propiedades físicas-mecánicas y las características anatómicas en tres niveles del eje longitudinal. Las probetas y los ensayos fueron realizados de 5 árboles con un diámetro y altura promedio de 25,6 cm y 25,8 m respectivamente, de acuerdo a las Normas Técnicas Peruanas para las propiedades físicas y mecánicas, y la norma de Procedimientos en estudios de anatomía de la Madera IBAMA para las evaluaciones anatómicas. Los resultados obtenidos mostraron que flexión estática (ELP y MOR), contracción tangencial y volumétrica total ...

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...
