Comparison of PalmDiversity betweensubplot of InobongPermanent ResearchPlot,Crocker Range Park. By AK MOHD RAFIQ BIN AK MATUSIN BS10110016
INTRODUCTION Arecaceae / palmae = 2800 species in 190 genera Has diversity in tropics and subtropics Vast ecological and economic importance Role as a source of raw materials for consumption, building, daily living for traditional cultures oil palm, date palm and coconut palm
INTRODUCTION Crocker Range Park : West Coast and interior plains of Sabah Focus on diversity of palm between C3 and D4 subplot of Inobong Permanent Research Plot.
OBJECTIVES To compare the DIVERSITY palm species between C3 and D4 subplots To CHECK LIST species found in both subplots
METHODS AND MATERIALS Location background * Crocker Range Park * Largest protected area in Sabah (139,919 ha) * 75 km long from northeast to southeast * Elevation ranges widely from lowland of 100 m to mountain

Study site C3 AND D4 SUBPLOTSFigure 2.0 Diagram of a 10 m x 10 m subplots in 50 m x 50 m plot(Ishida et al., 2006).
Fieldsampling : number of individual in C3 and D4 subplot will be counted Circumstances of more than 3cm Data analysis : Simpson Diversity Index ni (ni – 1) Ds = 1 - -------------- = Simpson Diversity N (N-1)
DATA ANALYSISSIMPSON DIVERSITY INDEXC3 SUBPLOTS: 0.59D4 SUBPLOTS: 0.378
DISCUSSION Total number of individual in both subplots : 25 Simpson Diversity Index show C3 subplot more diverse than D4 subplot although D4 have 2 subfamilies 2 same species are found in both subplots-: Calamus comptus-: Calamus marginatus
3 species of Calamoideae found in both sites are classified as climbing undergrowth rattan Rattan can inhibit in a wide range of habitat from 0 to 3000m above sea level Mostly found in lowland rain forest Thus, these 3 species can occupy both study sites Calamus comptus, Calamus marginatus, Calamus convallium
Most abundance palm genus in C3 subplot is Calamus sp. Simpson Diversity Index, C3 (0.59) more diverse than D4 (0.378) C3 and D4 located at different soil surface condition. C3 subplot located at low elevation than D4 subplots C3 watery soil, near with small water flow channel Calamus sp. tend to grow rapidly in this area Apply in palm plantation
CONCLUSIONTotal individual 25.Study the changes trend of diversity along the subplotApply in plantation, economic uses, natural ecosystem
