Abstract
La actividad selectiva del aprovechamiento forestal origina áreas boscosas remanentes cuya diversidad es alterada en diferente medida. El estudio se realizó con el objetivo de proveer información de la situación actual de la diversidad y composición arbórea de dos bosques con diferente nivel de alteración, ubicados en la Estación Experimental Agropecuaria Satipo en el distrito de Río Negro - Satipo. Se establecieron parcelas de muestreo de 1.0 ha por tipo de bosque. Se encontró diferencias en la cantidad de individuos, familias, géneros y especies; la familia Euphorbiaceae, la más abundante en el bosque secundario tardío y bosque maduro, los géneros Pseudosenefeldera y Sapium fueron más abundantes en número de individuos, predominado Pseudosenefeldera inclinata en la parcela del bosque secundario tardío y en el bosque maduro, Sapium glandulosum. Los valores más relevantes del Índice de Valor de Importancia (IVI) de familias del bosque secundario tardío fueron: Euphorbiaceae (69.75%), Moraceae (25.37%), Lauraceae (22.66%) y Fabaceae (20.64%); en el bosque maduro, Moraceae (46.98%), Euphorbiaceae (36.62%), Fabaceae (28.83%), Malvaceae (22.03%) y Rubiaceae (18.03%); mientras, el IVI de especies del bosque secundario tardío con más altos valores: P. inclinata (54.2%), Meliosma frondosa (17.9%), Trattinnickia peruviana (17.2%), Pourouma cecropiifolia (11.8; en la parcela del bosque maduro, S. glandulosum (19.8%), Ficus insípida (17.8%), Zapoteca amazonica (12.2%), Meliosma frondosa (11.1%), Sterculia apeibophylla (9.9%) y Alseis peruviana (9.9%). El volumen maderable fue de 105.077 m3 en el bosque secundario tardío y 78.198 m3 en el bosque maduro. Para el manejo sostenible del bosque se considera realizar la evaluación, monitoreo, aprovechamiento de recursos arbóreos mediante un plan de manejo con fines de conservación. Se concluye que el bosque en general se encuentra en plena actividad sucesional y posee alta diversidad.
The selective activity of forest harvesting gives rise to many remaining wooded areas whose diversity is altered to different degrees. The study was conducted with the aim of providing information on the current situation of tree diversity and composition in two forests with different levels of alteration, located at the Satipo Agricultural Experimental Station in the Rio Negro - Satipo district. Sampling plots of 1.0 ha were established for each forest type. Differences were found in the number of individuals, families, genera and species; the Euphorbiaceae family was the most abundant in the late secondary forest and mature forest, the Pseudosenefeldera and Sapium genera were more abundant in number of individuals, with Pseudosenefeldera inclinata predominating in the late secondary forest plot and Sapium glandulosum in the mature forest. The most relevant values of the Importance Value Index (IVI) of late secondary forest families were: Euphorbiaceae (69.75%), Moraceae (25.37%), Lauraceae (22.66%) and Fabaceae (20.64%); in the mature forest, Moraceae (46.98%), Euphorbiaceae (36.62%), Fabaceae (28.83%), Malvaceae (22.03%) and Rubiaceae (18.03%); Meanwhile, the IVI of late secondary forest species with the highest values: P. inclinata (54.2%), Meliosma frondosa (17.9%), Trattinnickia peruviana (17.2%), Pourouma cecropiifolia (11.8; in the mature forest plot, S. glandulosum (19.8%), Ficus insipida (17.8%), Zapoteca amazonica (12.2%), Meliosma frondosa (11.1%), Sterculia apeibophylla (9.9%) and Alseis peruviana (9.9%). The timber volume was 105,077 m3 in the late secondary forest and 78,198 m3 in the mature forest. For the sustainable management of the forest, it is considered to carry out the evaluation, monitoring, and use of tree resources through a management plan for conservation purposes. It is concluded that the forest in general is in full successional activity and has high diversity.
