La deforestación de bosques va alcanzando cifras alarmantes en el Perú por falta de estudio de especies que puedan suplir a la madera, tal como el bambú Guadua angustifolia Kunth., que presenta un gran potencial, pero por falta de evaluación de sus propiedades mecánicas no es utilizado ni aprovechado óptimamente; para ello se plantearon los objetivos tales como determinar los esfuerzos de flexión, compresión paralela y perpendicular y de cizallamiento a tres niveles de altura (base, medio y ápice). La investigación se realizó en el Laboratorio de Tecnología de la Madera de la Facultad de Ciencias Forestales de la Universidad Nacional de Ucayali (UNU), utilizando bambú Guadua angustifolia Kunth., extraída del Fundo de la Facultad de Agronomía de la Universidad Nacional Agraria de la Selva (UNAS); los datos obtenidos de los ensayos mecánicos, se integraron con respecto a la...

Se evaluaron los impactos a la vegetación provocados por el aprovechamiento de recursos forestales maderables en la parcela de corta Nº 05 de la Concesión. Los impactos negativos se expresaron en valores monetarios. La investigación fue aplicada, transversal y descriptiva, en una muestra efectiva de 287 ha de una población de 8.272 ha. Se aplicó el método inductivo, técnicas de línea base en las áreas asignadas para cada actividad del aprovechamiento forestal y observación directa de los impactos a la vegetación. Para la valoración económica de bienes se utilizó la Resolución Directoral Ejecutiva N° 241-2016- SERFOR-DE (vegetación maderable) y Resolución Directoral Ejecutiva N° 171- 2016-SERFOR-DE (vegetación no maderable); mientras que para la valoración económica de servicios ecosistémicos se utilizó el valor de bono de carbono del año 2020 (24 euros = S/. 87,...

Knowing the timber economic value standing is an important element to achieve efficient management and pursue sustainable development, emphasizing social welfare. For this reason, the research evaluated four plantations of Eucalyptus globulus Labill, distributed in four annexes of the Daniel Hernández district, belonging to the province of Pampas Tayacaja. A total of 77 individuals were inventoried in four installed strips (one strip per plantation) 50 m long and 2 m wide. Quantitative variables (height and diameter of the trees) and qualitative variables (quality of shaft and age of the trees) were evaluated in order to obtain the timber economic value of the four strips. As a result, it was reported that 18,2 % of the trees are more than 40 cm in diameter and are in a usable situation; However, 79,2 % have stem 2 and 3 qualities, which implies that silvicultural treatments should be p...

At present, environmental requirements and the growth of environmental management systems, have generated a change of consciousness at an industrial level, leading this to satisfy the expectations of customers both in the quality of products or services, as well as in the ways environmentally friendly production facilities, the above added to environmental regulations, have generated a change in the production culture in which the enormous losses of raw materials that are discarded into the sewers must be recovered and reincorporated into the production process, resulting in in economic and environmental benefits. In the city of Pampas Tayacaja there is a very latent problem which is the lack of water treatment, which is why most of the population often uses contaminated water in their food thus causing some diseases. For this reason, in this present work an investigation will be propose...

The objective of the research was to know the dynamics of the reserved forest of Tingo María, through the analysis of the conditions of increase, mortality and recruitment; as well as the silvicultural conditions (lighting and shape of the canopy, stem quality and lianas infestation), in order to carry out the sustainable management of this forest. Four permanent measurement plots of 1 ha each were installed, divided into sub-plots for the evaluation of natural regeneration categories, such as saplings, low saplings, high saplings and stems. The results reported a total of 1487 individuals in the four PPMs, of which 761 individuals were in the stem category. The highest percentages of average annual increase, mortality and recruitment were recorded in the jumping category, with values of 2.2, 6.6 and 23.7%, respectively. Likewise, most individuals are free of lianas, reporting very stra...

The objective of the research was to identify the non-timber forest products (NTFP) marketed in the Viñas Population Center. The methodology used was theoretical and analytical, in terms of the type of research it is descriptive and documentary to analyze the current and potential natural resources of the Poblado de Viñas Center. The results show the importance of NTFPs in various conservation and development projects, with emphasis on production and trade in medicinal, ornamental and timber issues, through the evaluation of the different forms of use and sustainability. Finally, it is concluded that the Viñas Population Center reports a great wealth of natural resources, which are essential for the community's economy.

The purpose of the research work was to evaluate the predominance of 2 types of organic liquid foliar fertilizer and 3 doses, in the quality of Cedrela odorata L seedlings. An Entirely Random Design was applied with a 2x3 factorial arrangement and 5 repetitions; the components under analysis were: element A: AFLF and AFLH, and component B: 50, 100 and 150 mL/20 L of water, generating 6 treatments plus a control; 525 seedlings were installed and evaluated over 5 months, after which the highest seedling elevation (19.70 cm) occurred with T5 (150 mL AFLF/20 L water) and the lowest elevation (18, 76 cm) with T1 (50 mL AFLF/20 L water), with high quality seedlings; the largest diameter (8.32 mm) was obtained with T4 (100 mL of AFLH/20 L water) and the smallest (7.41 mm) in T0, with high quality seedlings; show high quality of height/diameter interaction or solidity index; the seedlings of the...

The success of forest management depends to a large extent on the availability of sufficient resources, so natural regeneration ensures the sustainability of resources over time, which is very important to create knowledge or scientific basis in relation to forest dynamics. For this reason, the research was developed with the aim of evaluating the natural regeneration of Alnus spp. (alder) and the relationship of the requirements of the aforementioned species with the environmental factors of the Pusqui and Dos de Mayo annexes, in the province of Tayacaja, Huancavelica region. The research area consisted of 146 individuals of natural regeneration between seedlings, saplings, low latizales and high latizales, of which 84 individuals were reported in the Dos de Mayo annex and 62 individuals in the Pusqui annex. The most abundant natural regeneration category in the two annexes was the low ...

The objective of the research was to carry out a diagnosis and propose silvicultural treatments in a plantation of Eucalyptus globulus Labill. The methodology was experimental. A census was carried out on 100% of the area (1 ha), which was divided into six subplots. In each subplot, quantitative and qualitative variables were evaluated. It was reported that 100% of the individuals corresponded to E. globulus Labill (1200 individuals). 11 diameter classes were reported, between 8 and 88 cm in diameter at breast height, of which 86.5% are between 8 and 50.99 cm, indicating that the plantation is not yet in the harvesting stage. Regarding the quality of the stem, 63.7% reported a straight stem; While in terms of phytosanitary status, 69.9% were in good condition, 21.8% reported mortality, 6.3% were shoots and 2% were leafless individuals, evidencing the need for treatments. Pruning treatmen...
