    Exotic plant species in the restoration project area in Ranupani recreation forest, Bromo Tengger Semeru National Park (Indonesia)

    ABSTRACT
    Exotic plant species invasiveness is the crucial issue in mountain forest ecosystems restoration programs. The aim of this research was identifying the diversity of exotic species in Tengger highlands. There are some important exotic plant species in Ranupani restoration area, including Salvinia molesta D. S. Mitch., Acacia decurrens Willd., A. mangium Willd., Eupatorium inulifolium Kunth., E. riparium Regel, Solanum pseudocapsicum Medik., Zantedeschia aethiopica (L.) Spreng., Lantana camara L., and Fuchsia magellanica Lam. Actually, among factors most favorable to exotic plants species invasion there are forest and habitat degradation. Clearing exotic plant species in restoration areas, building community awareness about exotic species and enhancing the capacity of national park management to control and monitor the existence of exotic plant species is extremely important.

    Plant trees species for restoration program in Ranupani, Bromo Tengger Semeru National Park Indonesia

    ABSTRACT
    Restoration programs in conservation areas need a basis data regarding plant species diversity which is indigenous for the restoration area target. The availability of such data is useful for selecting appropriate plant species for reintroduction programs as a crucial part in restoration programs. The aim of this paper is to identify potential plant trees species for a restoration program in tropical highland ecosystem. There are potential plant trees species for Ranupani area, including Acer laurinum, Acmena acuminatissima, Casuarina junghuhniana, Dacrycarpus imbricatus, Engelhardtia spicata, Myrsine korthalsii, Lithocarpus sundaicus, Lithocarpus korthalsii, Macropanax dispermum, Trema orientalis, Turpinia sphaerocarpa, Omalanthus giganteus, and Astronia spectabilis. Some of them, i.e. Engelhardtia spicata, Omalanthus giganteus, Astronia spectabilis, Trema orientalis and Casuarina junghuhniana play an important role as pioneer species. In the first step of restoration program implementation, these species can be planted with some pioneer native shrubs and herbs to initiate and accelerate the succession process in the restoration areas.
