Abstract
El objetivo de la investigación fue contribuir al conocimiento de la dinámica forestal en bosques de colinas altas en el Perú, realizado en el Bosque Reservado de la Universidad Nacional Agraria de la Selva, Tingo María – Huánuco. Evaluado en una parcela permanente de una hectárea, todos los individuos arbóreos > 10 cm de dap, para un periodo intercensal de 6 años (2015 y 2021). Encontrando tasa de mortalidad y reclutamiento de 3,77% y 4,68% respectivamente; de los cuales, 5 familias y 5 especies muestran tasas mas altas de mortalidad: Lauraceae (6,13%), Moraceae (5,81%), Melastomataceae (5,17%), Salicaceae (5,09%) y Burseraceae (5%) y Toulicia reticulata (32,43%), Ocotea olivacea (23,10%), Micropholis gnaphaloclados (18,31%), Protium opacum (15,27%) y Helicostylis scabra (14,42%), respectivamente. En cuanto al reclutamiento, 5 familias y 5 especies presentan tasas mas altas: Urticaceae (9,52 %), Vochysiaceae (9,44%), Lauraceae (7,36%), Euphorbiaceae (4,86 %) y Rubiaceae (4,19%) y 5 especies: Cecropia sciadophylla (25,07%), Pourouma mollis (21,65%), Rhodostemonodaphne kunthiana (18,31%), Qualea paraensis (13,31%) y Schizocalyx peruvianus (11,55%) respectivamente. El incremento medio anual en el área basal fue de 0,51 m2 y la tasa anual del crecimiento porcentual en área basal es de 3,77%. El incremento medio anual del diámetro obtenido es de 0,41 cm, con una tasa anual de crecimiento diamétrico 2,03%. El aspecto estructural y maderable del bosque, en su mayoría presentan una calidad de fuste comercial en el futuro (83,46%), forma de copa de medio circulo (42,75%), iluminación de copa vertical parcial (38,85%) y con escasa presencia de trepadoras leñosas y/o sin lianas (64,59%). Las especies arbóreas monitoreadas muestran tasas anuales de crecimiento, mortalidad y reclutamiento sujeto a perturbaciones naturales y pendiente propias de bosques de colina alta.
The objective of this research was to contribute to the understanding of forest dynamics in highland forests in Peru. This research was conducted in the Reserved Forest of the National Agrarian University of the Selva, Tingo María – Huánuco. All tree individuals >10 cm dbh were evaluated in a permanent one-hectare plot over a six-year intercensal period (2015 and 2021). Mortality and recruitment rates were found to be 3,77% and 4,68%, respectively; Of which, 5 families and 5 species show higher mortality rates: Lauraceae (6,13%), Moraceae (5,81%), Melastomataceae (5,17%), Salicaceae (5,09%) and Burseraceae (5%) and Toulicia reticulata (32,43%), Ocotea olivacea (23,10%), Micropholis gnaphaloclados (18,31%), Protium opacum (15,27%) and Helicostylis scabra (14,42%), respectively. Regarding recruitment, 5 families and 5 species presented higher rates: Urticaceae (9,52%), Vochysiaceae (9,44%), Lauraceae (7,36%), Euphorbiaceae (4,86%) and Rubiaceae (4,19%) and 5 species: Cecropia sciadophylla (25,07%), Pourouma mollis (21,65%), Rhodostemonodaphne kunthiana (18,31%), Qualea paraensis (13,31%) and Schizocalyx peruvianus (11,55%) respectively. The average annual increase in the basal area was 0,51 m2 and the annual percentage growth rate in basal area is 3,77%. The average annual increase in diameter obtained is 0,41 cm, with an annual diameter growth rate of 2,03%. The forest's structural and timber characteristics mostly show future commercial stem quality (83,46%), a semicircular crown shape (42,75%), partial vertical canopy illumination (38,85%), and a scarce presence of woody climbers and/or without lianas (64,59%). The monitored tree species show annual growth, mortality, and recruitment rates subject to natural disturbances and slopes typical of high-hill forests.
