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
8. Study site
C3 AND D4 SUBPLOTS

9.
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)
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
