Abstract:
Pigafetta filaris (Giseke) Becc is the one of the palm species that declared rare by Indonesian Institute of Science at 2001. The aim of this study is to uncover the ecological aspect of P. filaris in Gunung Meja Natural Tourism Park of Manokwari and also to provide recommendations for the future existence the palm. The main purpose of the study is to determine the ecological aspect of the P. filaris and also number of palm species based on its growing phases as well as measuring surrounding growing habitat of other species. The result pointed out only 2 individual species found at mature phase. Soil chemical analysis noted pH 5.5, P 3.31, K 1.13, Ca 3.61, Na 2.04, Mg 0.87, cation exchange capacity 49.45, and soil nutrition rate of P. filaris that was in medium range with black color, dusty clay soil texture, and with crumb structure. Climatic factor indicated the average temperature of 29° C, relative humidity of 69%, and tree crown coverage 57.5%. Topographical factor of P. filaris indicated the growing habitat ranged between 100-120 above sea level, slope ranged between 15-45%. Woody plants that set up the association with P. filaris have found such as Pometia coreacea and Pometia pinnata. The conservation status of P. filaris has been concerned and ecologically it will be extinct in Gunung Meja Natural Tourism Park of Manokwari
