Abstract


Rattan jernang is one of the non-timber forest products of Bukit Duabelas National Park (TNBD). Bukit Duabelas National Park is one of the conservation areas located entirely in Jambi Province. This area has high enough potential of biodiversity. This study aims to identify the types of jernang within the park area, to identify the number of jernang/clumps, to analyze the growth rate and mapping of jernang within the park area. The research location in this area is divided into 3 parts: Demonstration plot jernang area which has been determined by Balai Besar National Park of Bukit Duabelas National Park (BDNP), outside of demonstration plot, and permanent plot made by CRC. Data were collected by purposive random sampling method and vegetative analysis covering species identification, measurement of individual number, and making of distribution map of rattan jernang. The results of the study showed that there are no Daemonorops on CRC plots (BF1, BF2, BF3, and BF4). The types of Daemonorops found in the demonstration plot area are Daemonorops draco of a single family and female. While outside the plot of CRC and the demonstration plot, found D. draco in TNBD was 7.1 and D. didymophylla. The mean individual number of D. draco in TNBD was 7.1 and D. didymophylla was 4.7. Level Growth Analysis of D. draco indicated of all levels of its growth, starting from the youngest till the aged one.
