Evaluación del desempeño y supervivencia de siete especies arbóreas bajo diferentes coberturas de plantación en la Reserva Forestal Protectora Bosque Oriental de Bogotá

Abstract

The performance and survival of seven tree species planted under different covers of exotic forest plantations were evaluated. The parameters analyzed are height, basal diameter and crown diameter. The incidence of the variables slope, crown density and fine necromass in the development of the seedlings was evaluated, and as a response variable, the regeneration recruited, exotic as native. Lower mortality rate and better performance in basal diameter growth were recorded under E. globulus, the latter in the species C. montana and M. leucoxyla associated with greater canopy opening and less amount of fine necromass. The highest mortality rate is recorded by E. paniculata, also being the species with the highest growth in height, R. rospigliosii in basal diameter and V. triphyllum in crown diameter. The most frequent and dominant species of the regeneration analyzed have an invasive character with a higher incidence under E. globulus.
