Abstract: Los bosques de neblina son una importante formación en los bosques húmedos tropicales, el presente tiene por objeto el estudio de la dinámica del bosque a través de sus diferentes fases: claro, construcción y madura, realizado en un bosque primario del distrito de Tabaconas, provincia de San Ignacio, departamento de Cajamarca. El análisis silvicultural se ejecutó en una formación representativa de 25 ha, correspondiendo a la fase de claro 25 ha, fase de construcción y madura 1 ha respectivamente. En el bosque primario los claros se generan formando un mosaico irregular, para las condiciones del bosque estudiado de presentan 11.36 claros/ha, predominando los claros pequeños (62%) y medianos (37%) sobre los claros grandes, la ocurrencia de estos últimos son escasos. En el proceso de establecimiento de claros, las causas mecánicas constituyen la principal causa de muerte de los árboles, el 47% mueren por quiebra del eje principal, 37% muere por desarraigamiento y el 10% muere de pie. El número de especies valiosas varia en las distintas fases, en la de claro se encontraron 778 árboles/ha y 10.47 m2/ha, construcción 922 árboles/ha y 14.69 m2/ha y la fase madura 406 árboles/ha y 21.05 m2/ha para individuos con Dap ≥ 5 cm. En general, la regeneración natural de las categorías inferiores brinzal, latizal y fustal esta garantizada, la dominancia de las especies heliófitas (Nectandra arnotiana y Nageia rospigliosii) se dan en las fases de claro y construcción, cambiando de composición y estructura en la fase madura siendo el aporte de las especies esciófitas (Prumnopitys harmsiana) importante. Finalmente, las intervenciones silviculturales están dirigidas al bosque primario de la fase madura, siendo el sistema policíclico el apropiado para este tipo de bosque, debido a las características estructurales y ecológicas de las especies que integran el sistema.
The cloud forests are an important formation in tropical rainforests, the object of the present study of forest dynamics across its different phases: clearing, construction and mature phase, realized in a primary forest of the district of Tabaconas, province of San Ignacio, department of Cajamarca. The silvicultural analysis was executed in a representative formation of 25 ha, corresponding to clearing phase 25 ha, construction and mature phase 1 ha respectively. In primary forest, clearings generated an irregular mosaic, present 11.36 clearings/ha, predominantly small clearigs (62%) and medium (37%) than large clearings. In the procces of establishment of clearings, mechanical causes constitute the main cause of death of trees, 47% dies for failure of the main axis, 37% dies for uprooting and 10% dies standing. The number of valuable species changes in the different phases, in clearing phase 778 trees/ha and 10.47 m2/ha, construction were found 922 trees/ha and 14.69 m2/ha and the mature phase 406 trees/ha and 21.05 m2/ha for individuals with Dap ≥ 5 cm. In general, the natural regeneration of the low categories of seedling, small pole stage, high pole stage and timber stage is guaranteed, the dominance of heliophilous species (Nectandra arnotiana and Nageia rospigliosii), occur in phases clear and construction, changing composition and structure in the mature phase, It is important contribution of sciophilous species (Prumnopitys harmsiana). Finally, silvicultural interventions are directed to primary forest of mature phase, polycyclic system is appropriated for this forest, due to structural and ecological characteristics of the species that integrate the system.
