Resumo: | This work evaluates the diameter growth of trees species of artificial gaps per ecological groups in a harvested forest considering two systems of harvest. The study was carried out in the Reserva de Biósfera Yabotí, in Misiones, Argentina. Fifteen permanent plots were established, each one with 4 hectares with effective area of measurement of one hectare. The three treatments were: conventional logging, reduced impact logging and control plot. All trees larger than 10 cm of diameter at breast height (DBH) were measured, before (1998) and after the harvest (2006). Eighty-five species were registered. The average DBH diameter growth for all species was 0.41 cm yr-1 in the gap area, and 0.31 cm yr-1 for the control plot. The average diameter growth was 0.36 cm yr-1 for the reduced impact logging and 0.42 cm yr-1 for the conventional logging. In forests with high diversity, ecological groups are an important tool for the management and conservation. The reduced impact logging would be considered a less aggressive alternative for the forests in this region. doi: 10.4336/2010.pfb.30.64.311 |

El estudio fue desarrollado en la Reserva de Biosfera Yabotí, Misiones, Argentina. Se instalaron 15 parcelas permanentes, de cuatro hectáreas cada una, con un área efectiva de medición de una hectárea. Los tratamientos fueron tres: cosecha convencional, cosecha de impacto reducido y parcela testigo. Se registraron todos los ejemplares arbóreos mayores a 10 cm de diámetro a la altura del pecho (DAP) antes (1998) y después de la cosecha (2006). La riqueza florística alcanzó un número de 85 especies. Para el conjunto de especies el crecimiento diamétrico promedio fue de 0,41 cm año-1 en área de claro y de 0,31 cm.año-1 en área testigo, siendo el promedio de crecimiento diamétrico de 0,36 cm.año-1 para impacto reducido y 0,42 cm año-1 para cosecha convencional. En bosques con alta diversidad florística, se debería considerar a los grupos ecológicos como una herramienta base para el manejo y conservación de los mismos. El aprovechamiento de impacto reducido debería ser considerado como una alternativa menos agresiva para los bosques de la región de Misiones.
