Item Cuantificación del carbono en la biomasa aérea de tres diferentes usos de la tierra en la cuenca de Aguaytía sectores: Irazola, curimaná y campo verde - Región Ucayali.(Universidad Nacional Agraria de la Selva, 2012) Salazar Hinostroza, Evelin Judith; Pocomucha Poma, Vicente SerapioSe desarrollaron estudios para la cuantificación del carbono en la biomasa aérea en tres diferentes sistemas del uso de la tierra, ubicados en seis sectores de los distritos Curimaná, lrazola y Campo Verde, región Ucayali; los sistemas estudiados fueron bosque primario remanente, pastizales y palma aceitera con más de 10 años de edad. Para ello se estratificó en 18 parcelas de 40 m x 50 m dentro de los seis sectores o cluster; donde en cada uno se incluye el bosque, palma aceitera y pasto. Para determinar la biomasa arbórea se utilizó la ecuación alométrica generada por CHAVE et al., 2005, para la vegetación no arbórea menor de 5 cm de diámetro se utilizó la ecuación alométrica generada por NASCIMIENTO y LAURANCE (2002), para la vegetación arbustiva y herbácea se utilizó el método directo, realizando muestras destructivas y para determinar la biomasa de la madera muerta se utilizó la ecuación alométrica generada por CHAO et al., 2008. El carbono en la biomasa aérea total determinada es: en el caso de bosque primario remanente presentaron 135.5 t/ha, seguido por los pastizales 21.4 t/ha y finalmente las plantaciones de palma aceitera que almacenaron 14.7 t/ha de carbono.Item MultiProduct Optimization of Cedrelinga cateniformis (Ducke) Ducke in Different Plantation Systems in the Peruvian Amazon(Forests, 2025) Baselly-Villanueva, Juan Rodrigo; Fernández-Sandoval, Andrés; Salazar Hinostroza, Evelin Judith; Cárdenas Rengifo, Gloria Patricia; Puerta, Ronald; Trigoso, Tony Steven Chuquizuta; Rufasto-Peralta, Yennifer Lisbeth; Vallejos-Torres, Geomar; Casas, Gianmarco Goycochea; Araújo Junior, Carlos Alberto; Quiñónez-Barraza, Gerónimo; Álvarez-Álvarez, Pedro; Leite, Helio GarcíaThis 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 × 5.08 cm) were identified as key contributors to maximizing volumetric yields. The highest yields were observed in mature plantations, in which the total log volume reached 508.1 m3ha−1 and the sawn lumber volume 333.6 m3ha−1. The findings demonstrate the power of data-driven decision-making in the timber industry. By combining precise modeling and optimization techniques, we developed a framework that enables sawmill operators to maximize log and lumber yields. The insights gained from this research can be used to improve operational efficiency and reduce waste, ultimately leading to increased profitability. These practices promote support for smallholders and the forestry industry while contributing to the long-term development of the Peruvian Amazon. © 2025 by the authors.
