  1. 1. Comparison of PalmDiversity betweensubplot of InobongPermanent ResearchPlot,Crocker Range Park. By AK MOHD RAFIQ BIN AK MATUSIN BS10110016
  2. 2. 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
  3. 3. 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.
  4. 4. OBJECTIVES To compare the DIVERSITY palm species between C3 and D4 subplots To CHECK LIST species found in both subplots
  5. 5. 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

  7. 7. 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).
  8. 8.  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)
  9. 9. RESULTS C3 SUBPLOT Species : 1. Calamus comptus 2. Calamus convallium 7% Calamus comptus 3. Calamus marginatus 40% Calamus convallium Calamus 53% marginatus Subfamily : Calamoideae
  10. 10. RESULTS D4 SUBPLOTS 10% 10% Species : Calamus comptus 1. Calamus comptus Calamus marginatus 2. Calamus marginatus Licuala ahliduri 3. Licuala ahlidurii 80% Subfamilies : Calamoideae & Coryphoidea
  11. 11. Calamus marginatus,
  12. 12. Calamus convallium (C3 subplot only)
  13. 13. Calamus comptus
  14. 14. Licuala ahlidurii ( only found in D4 subplot)
  15. 15. DATA ANALYSISSIMPSON DIVERSITY INDEXC3 SUBPLOTS: 0.59D4 SUBPLOTS: 0.378
  16. 16. 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
  17. 17. 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
  18. 18.  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
  19. 19. CONCLUSIONTotal individual 25.Study the changes trend of diversity along the subplotApply in plantation, economic uses, natural ecosystem
