Seedling growth of some native trees in Ranu Pani- Ranu Regulo restoration area, Bromo Tengger Semeru National Park
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 6
Abstract
The aim of the research was to classify seedling of native plant species in restoration programs based on species’ responses to planting time, species’ competitiveness to invasive species, and shading cover. We observed the growth rates and growth characteristics of Acer laurinum Hassk., Acmena acuminatissima (Blume) Merr. & L. M. Perry, Aglaia odoratissima Blume, Dodonaea viscosa Jacq., Engelhardia spicata Bl., Ficus sp., Homalanthus giganteus Zoll. & Mor., Lithocarpus sundaicus (Blume) Rehd. Macropanax dispermum Kuntze., Pittosporum moluccanum (Lamk.) Miq. and Vernonia arborea Buch.-Ham in two sites—the first site was without exotic species and the second site was with abundant exotic species. The first observation was done six months after planting and the second observation was done twelve months after planting. Species’ survival together with plant’s height, stem diameter, emerging buds and young leaves was observed and measured. The results of the study showed that eleven seedling species each showed different responses to their planting environment (absence and presence of exotic species), planting time, and covering application. These seedling species fundamentally can be clustered in three clusters, namely plant with less adaptation, plant with moderate to good adaptation, and plant with most adaptation characters. Pioneer species shows its ability to grow in different planting times, survive under exotic plant species invasion, and adapt to frost attack. However, climax species need assistance and protection in order to enhance its survival. This study confirmed that in each restoration program, introducing pioneer species in the beginning of planting program could be significant.
