         Interim profile, incomplete information
    Taxonomic name: Arenga obtusifolia Mart.
    Synonyms:
    Common names: langlap (Indonesia), sugar palm
    Organism type: palm
    The sugar palm Arenga obtusifolia commonly known as 'langkap' in Indonesia, covers an estimated 18, 000 hectares of the Ujung Kulon peninsula (part of the World Heritage Site, Ulung Kulon National Park, Java), home to the 'Critically Endangered (CR)' Javan Rhinoceros (Rhinoceros sondiacus). The spread and dominance of A. obtusifolia has negative impacts on undergrowth that comprises the food of the Javan Rhino; including seedling regeneration because of shading and poor light conditions caused by the canopy of the palm. Since 2003, studies have been underway to find an effective way of controlling this invasive species. Direct injections with RoundUp herbicide have proven to effectively kill the palm without leaving harmful chemical traces in the soil.
