Abstract

The Arecaceae family holds significant ecological and economic value and is widely distributed in tropical regions, including Indonesia. This study aimed to inventory the Arecaceae species found in the Lembah Bukit Manjai Tropical Rainforest Biodiversity Park. A descriptive exploratory method was employed using field research and purposive sampling techniques. Data collection involved direct observation, morphological documentation, and species identification based on taxonomic references. The results identified five Arecaceae species: Arenga pinnata, Calamus manan, Caryota mitis, Calamus zollingeri, and Licuala spinosa. Species distribution was influenced by abiotic environmental factors such as light intensity, temperature, humidity, and soil pH. Calamus manan was the most dominant species, while Caryota mitis was the least encountered due to its low ecological tolerance. This study underscores the importance of biodiversity conservation and the use of inventory data as a foundation for sustainable tropical ecosystem management. Furthermore,  it contributes to the development of local taxonomic databases and documentation of potentially endemic species in South Kalimantan.

Abstract

South Kalimantan is known for its rich biodiversity, particularly within the Tropical Rainforest Biodiversity Park of Lembah Bukit Manjai, which serves as a habitat for various tropical forest plant species. Among these is the genus Amorphophallus, notable for its ecological, economic, and conservation value. These plants typically grow in shaded and humid forest floors. This study aimed to identify and describe Amorphophallus species present in the study area. A descriptive-exploratory method was applied using purposive sampling. The study recorded three species: Amorphophallus muelleri, A. paeoniifolius, and A. borneensis. These species were found thriving under low to moderate light intensity, high soil moisture, and neutral pH. Key morphological traits such as habit, leaves, stems, and roots were documented for each species. The findings indicate that the ecological conditions of the study area strongly support the growth of Amorphophallus spp., and that these plants hold potential as local biodiversity-based learning resources.
