| description | Tropical montane cloud forests (TMCF) are under severe threat from deforestation, fragmentation and degradation. Several tree species are harvested and commercialized by local communities through unplanned selective logging. Lack of information regarding the growth rates of the most economically valuable timber species hampers the design of effective sustainable management schemes for TMCF. The objective of this study was to determine the diameter growth rates and evaluate the influence of tree size, crown class and neighbouring tree basal area on the growth of common and valuable TMCF timber species. Annual diameter growth was measured during two years in 60 trees (10 to 45 cm in diameter at breast height; dbh) each of Alnus acuminata, Liquidambar styraciflua and Quercus xalapensis, located in two unmanaged secondary TMCF sites in Veracruz, Mexico. High diameter growth rates (centimeter per year [cm yr-1]; mean ± SE) were recorded in the three species; the highest was recorded in A. acuminata (1.62 cm yr-1 ± 0.08 cm yr-1), followed by Q. xalapensis (0.91 cm yr-1 ± 0.07 cm yr-1) and L. styraciflua (0.71 cm yr-1 ± 0.08 cm yr-1). Diameter growth rate was inversely related to the basal area of the neighbouring trees, indicating a negative effect of competition in the three species. Dominant trees had higher growth rates than supressed trees in the three species. The high growth rates recorded in forests with no previous management and the negative effect of basal area of neighbouring trees support the potential for silvicultural management in secondary TMCF. |

Numerosas especies arbóreas del bosque mesófilo de montaña (BMM) o bosque de niebla, son aprovechadas por las comunidades locales a través de tala selectiva no planificada. La falta de información de las tasas de crecimiento de las especies más valiosas económicamente limita el diseño de esquemas efectivos para el manejo sustentable del BMM. El objetivo de este estudio fue determinar las tasas de crecimiento diamétrico y evaluar la influencia del tamaño del árbol, la posición en el dosel y el área basal de los árboles vecinos en el crecimiento de especies maderables comunes del BMM. Se midió el crecimiento anual diametrico en 60 individuos por especie (10 cm a 45 cm de diámetro) de Alnus acuminata, Liquidambar styraciflua y Quercus xalapensis, durante dos años en dos sitios de BMM secundario, Veracruz, México. Altas tasas de crecimiento diamétrico (centímetros por año [cm año-1]; promedio ± EE) fueron registradas en las tres especies; la mayor se registró en A. acuminata (1.62 cm año-1 ± 0.08 cm año-1), seguido por Q. xalapensis (0.91 cm año-1 ± 0.07 cm año-1) y L. styraciflua (0.71 cm año-1 ± 0.08 cm año-1). En las tres especies la tasa de crecimiento estuvo inversamente relacionada con el área basal de los vecinos, indicando el efecto negativo de la competencia. Los árboles dominantes presentaron tasas de crecimiento mayores que los árboles suprimidos en las tres especies. Las altas tasas de crecimiento registradas en bosques sin manejo previo y el efecto negativo del área basal de los vecinos apoyan el potencial para el manejo silvícola en BMM secundarios.
