Permanent Research Plot,Crocker Range Park.

INTRODUCTIONArecaceae / palmae = 2800 species in 190 generaHas
diversity in tropics and subtropicsVast ecological and economic
importanceRole as a source of raw materials for consumption,
building, daily living for traditional cultures oil palm, date palm
and coconut palm
INTRODUCTIONCrocker Range Park : West Coast and interior plains
of SabahFocus on diversity of palm between C3 and D4 subplot of
Inobong Permanent Research Plot.
OBJECTIVESTo compare the DIVERSITY palm species between C3 and
D4 subplotsTo CHECK LIST species found in both subplots
METHODS AND MATERIALSLocation 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).
Field sampling : 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)
RESULTS C3 SUBPLOTSpecies : 1. Calamus comptus 2. Calamus
convallium 3. Calamus marginatus
Subfamily : Calamoideae
RESULTSD4 SUBPLOTSSpecies : 1. Calamus comptus 2. Calamus
marginatus 3. Licuala ahlidurii
Subfamilies : Calamoideae & Coryphoidea
Calamus marginatus,
Calamus convallium (C3 subplot only)
Calamus comptus
Licuala ahlidurii ( only found in D4 subplot)
DATA ANALYSISSIMPSON DIVERSITY INDEX
C3 SUBPLOTS: 0.59D4 SUBPLOTS: 0.378
DISCUSSIONTotal number of individual in both subplots : 25
Simpson Diversity Index show C3 subplot more diverse than D4
subplot although D4 have 2 subfamilies2 same species are found in
both subplots -: Calamus comptus -: Calamus marginatus
3 species of Calamoideae found in both sites are classified as
climbing undergrowth rattanRattan can inhibit in a wide range of
habitat from 0 to 3000m above sea levelMostly found in lowland rain
forestThus, these 3 species can occupy both study sitesCalamus
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 subplotsC3 watery soil, near with small water
flow channelCalamus sp. tend to grow rapidly in this areaApply in
palm plantation
CONCLUSIONTotal individual 25. Study the changes trend of
diversity along the subplotApply in plantation, economic uses,
natural ecosystem
