Dinámica de juveniles de seis especies arbóreas en un robledal intervenido de la cordillera de Talamanca, Costa Rica
Diameter and height growth patterns, as well as seedling and sapling mortality were studied over five years in a montane forest under two types of silvicultural intervention. The study is based on annual measurements of individuals marked six months after harvest. In the case of seedlings, the parameters evaluated were: total height and diameter at 10 cm from the base. For the sapling category, the diameter at 1.30 m was also measured. The Clark and Clark (1992) methodology was used to evaluate the crown illumination index of all individuals. Six tree species were studied: Quercus costaricensis, Quercus copeyensis, Ocotea austinii, Drymis granadensis, Weinmannia pinnata, Podocarpus macrostachyus. The Q. copeyensis seedlings showed the highest diameter and height growth rates, with annual mean increments in diameter of 3.2 mm/years and height of 28 cm/years. The Q. costaricensis saplings had the greatest diameter and height growth, with rates of 3.6 mm/year and 43 cm/year, respectively. Quercus species showed diameter and height growth rates significantly correlated with the crown light index for the seedling and sapling category. Seedlings had the highest mortality rates in all species.
