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. 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. OBJECTIVES
 To compare the DIVERSITY palm
species between C3 and D4
subplots
 To CHECK LIST species found in both
subplots

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

10.  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)

11. RESULTS
 C3 SUBPLOT
 Species :
1. Calamus comptus
2. Calamus convallium
7%
Calamus comptus
3. Calamus marginatus
40%
Calamus
convallium
Calamus
53%
marginatus
 Subfamily : Calamoideae

12. 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

13. Calamus marginatus,

14. Calamus convallium (C3 subplot only)

15. Calamus comptus

16. Licuala ahlidurii ( only found in D4 subplot)

17. DATA ANALYSIS
SIMPSON DIVERSITY INDEX
C3 SUBPLOTS: 0.59
D4 SUBPLOTS: 0.378

18. 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

19. 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

20.  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

21. CONCLUSION
Total individual 25.
Study the changes trend of
diversity along the subplot
Apply in plantation, economic
uses, natural ecosystem
