Floristics and structure of a lowland dipterocarp forest at Wanariset Samboja, East Kalimantan, Indonesia. Reinwardtia
12(4): 301– 323. — The results of a floristic inventory of trees with DBH < 10 cm in a lowland dipterocarp forest in East
Kalimantan show that 553 species of 192 genera in 62 families, represented by 5847 individuals, with the total basal
area of 350.01 m2 occurred in the plot of 10.5 hectare sampled. The two leading families in terms of number of species
were Myrtaceae and Lauraceae while according to the total sum of importance values for families were
Dipterocarpaceae and Euphorbiaceae. The forest had the second highest species richness in Indonesia. We recorded
25 species of dipterocarps , constituting 4.53 % of total species with basal area of 85.53 m2. or 24.44 % of the total
basal area in the plot. Shorea laevis (a diptererocarp) and Pholidocarpus majadum, (a palm) were the most prominent
species occurring here and were two of the ten leading species. The species-area curve rose steadily even up to an
area of 10.5 hectare, with a very slight indication of levelling off at about five hectares, indicating high heterogeneity
of the forest. Three largest trees were Shorea pauciflora (DBH = 196.50 cm) Dipterocarpus cornutus (DBH = 170.90
cm), and Alstonia scholaris (DBH = 170.00 cm) , Some species could be identified as fruit trees and medicinal plants.

REINWARDTIA
INTRODUCTION
Borneo is widely acknowledged as one of the
most important centers of plant diversity in the
world as well as the center of distribution and
species diversity for a large number of families
and genera within the Malesian archipelago
(Whitmore, 1986; Soepadmo, 1995). The most
widespread forest ecosystem in Borneo is the mixed
dipterocarp forest, mainly characterised by a 40-60
m tall canopy dominated by an association of
species of the Dipterocarpaceae family. This forest
shows the greatest number of species of any rain
forest ecosystem in Malesia (Whitmore, 1986;
Philips et al., 1994). Mixed dipterocarp forests are
also one of the most productive in the tropics and
have been extensively logged during the last 30
years. Harvesting rates range from 80 to100 m3 ha-1
whereas in other parts of the tropics they do not
exceed 30 to 50 m3 ha-1 (Sist, 2000). In Kalimantan,
most of the lowland dipterocarp forests have been
heavily logged and now the hill forests of the
interior constitute the remaining primary forest and
the main source of timber. Current knowledge of
the ecology, floristics, structure and species richness
of the lowland mixed dipterocarps forests is mainly
based on studies carried out in Sabah, Brunei and
Sarawak (e.g. Burgess,1961; Ashton, 1964;
Nicholson, 1965; Bruenig, 1969, 1970, 1973; Proctor
et al., 1983; Baillie et al., 1987; Ashton et al., 1992;
Newberry et al., 1992; Davies & Becker, 1996).
For Kalimantan, the studies remain few
(Kartawinata et al., 1981; Riswan, 1982; Guhardja
et al., 2000; Riswan, 1987a & b; Suselo & Riswan,
1987; Partomihardjo et al., 1987; Soekardjo et al.,
1990; Setiadi et al., 1996; Soedjito, 1990; Soedjito
& Kartawinata, 1995; Sist & Saridan, 1999;
Tanuwijaya et al., 1996). A floristic analysis of the
lowland dipterocarp forests of Borneo found that
on a regional scale, diversity is highest in southeast Borneo and central Sarawak with
Dipterocarpaceae as the most common family
followed by Euphorbiaceae and several
geographically distinct floristic regions could be
detected. (Slik et al. 2003). Based on data from
Northern Borneo, mainly Sarawak, Brunei and
Sabah, it was suggested that forests of western
Borneo were significantly richer in dipterocarp
species than those of eastern Borneo (Ashton, 1989;
Davies & Becker, 1996). The richness of the
lowland rainforest of Sarawak and Brunei might
be linked to the higher climatic stability of Northwestern Borneo which experiences less dramatic
and severe drought periods attributed to El Niño-
[VOL.12
Southern Oscillation (ENSO) events than the eastern
part of the island, especially Sabah (Ashton, 1989;
Goldammer et al. 1996; Walsh; 1996,) and East
Kalimantan (Guhardja et al. 2000; Leighton &
Wirawan 1986; ). However, Sist & Saridan (1999)
recently reported that the species richness of the
mixed dipterocarp forest of Berau in East
Kalimantan, in spite of its eastern location and its
proximity to Sabah was much higher than that of
the forest of Sabah and similar to that recorded in
Sarawak. Similarly, the forest at Wanariset Samboja,
was reported to be the richest in Borneo and even
in the world (Kartawinata et al. 1981, Whitmore
1986). These facts clearly show that our knowledge
of the floristic richness and variability of the mixed
dipterocarp forest of Kalimantan is still limited.
During the last two decades, the forest of
Kalimantan has been depleted and is disappearing
at an alarming rate. The main causes are intensive
and uncontrolled logging, and conversion into
industrial plantations. Successive fires following
land clearing affected million of hectares during El
Nino events (Sunderlin and Resosudarmo, 1996;
Dennis, 1999). Regeneration after fires in East
Kalimantan was mainly through seedbank
germination in lowland dipterocarp forest and
through repsrouting in kerangas ( Riswan 1982;
Riswan & Kartawinata 1988a, 1989) and
dipterocarp forests. The regeneration developed
better in the twice-burnt area than that in the area
burnt once and the density of young trees was higher
and even exceeded that of primary forest (Eichhorn
2006). Furthermore, in the burnt forest, the survival
and sprouting capacity of primary forest trees and
seedling establishment of pioneer trees and shrubs
suppressed the establishment of non-forest species
and post fire vegetation was found to be less
resilient than it was presumed (Nieuwstadt 2002;
Nieuwstadts et al. 2001,). Fires resulted in changes
of forest structure and composition, loss of tree
species diversity and invasion of pioneer species.
In sum, forest recovery was not only affected by
burning but also by environmental changes resulting
from fire (Simbolon et al. 2005)
A better knowledge of basic ecological
information, including floristic composition and
structure of the forest, are necessary for development
of a sustainable forest management scheme. To date,
there are still very few detailed descriptions and
quantitative assessments of forest floristics and
structure from a huge area of the Malesian rain
forests (Whitmore & Sidiyasa 1986) and for
Indonesia. Kartawinata (2005) reviewed the state
of quantitative vegetation studies from 1960’s
2008]
KARTAWINATA et al:: Wanariset dipterocarp forest structure
onwards and recommended a list of future actions
on the subject. The Lembaga Biologi Nasional
(National Biological Institute), now known as Pusat
Penelitian Biologi (Research Center for Biology)
noted such needs and in the mid 1970s initiated
and integrated the vegetation analysis project into
its overall biological research program (Kartawinata
2005). The present study was a part of this program
presenting a basic descriptive account of the
structure and floristic composition of a 10.5 ha
permanent plot set up in a lowland mixed
ditperocarp forest in Wanariset Samboja in East
Kalimantan. It was intended for use by various
future studies in order to provide a permanent basis
for long-term study of forest dynamics and floristic
changes. In this paper, analysis of the species
inventory data collected in the plots will be limited
to the description of the forest in terms of the main
structural parameters (basal area and density),
species richness, pattern of relative abundance and
family composition, integrating also data from a
1.6 ha section of this plot reported earlier by
Kartawinata et al. (1981) and on forest gaps by
Partomihardjo et al. (1987).
STUDY SITE AND METHODS
The study area is located within a 500-ha
research forest managed by the Wanariset (Field
Research Station) of the Forest Research and
Development Agency (FORDA) of the Ministry
of Forestry of Indonesia at Samboja, District of
Kutai Kertanegara, East Kalimantan, Indonesia at
0o 59’ Lat. and 116o 57’ Long, about 38 km north
of Balikpapan (Figure 1). The physiography is
undulating to flat. The forest is lowland dipterocarp
forest on dryland with small patches of seasonally
swampy ground. The elevation varies between 3
to about 50 m above sea level. The climate is
everwet and belongs to the rainfall type A with the
ratio between dry and wet months (Q) of 4.4
(Schmidt and Ferguson, 1951). The mean annual
rainfall recorded at the nearest meteorological
station (Balikpapan BP (Woods and Bower, 1982))
was 2425 mm for the period of 1927-1980. The
mean monthly rainfall ranged from126 mm in
October to 236 mm in March (Figure 1) and the
mean annual number of raindays was 145 with the
mean number of monthly raindays ranging from 9
to 14. The forest is situated on the Red Yellow
Podsolic Soil and occurs on an alluvial plain of
upper Miocene sedimentary rocks (Soepraptohardjo, 1972).
303
A block of 150m x 700 m was set up in 1979
in an undisturbed location within a lowland
dipterocarp forest about 50 m to the north of Km
1.6 of the now Semboja-Semoi-Sepaku road. It was
constructed by sequentially placing a series of 10
m x 10 m plots, first along the width of the block,
thus forming a 150 m x 10 m transect consisting
of 15 plots; with the surface of each plot was parallel
to the ground. The second, third ….. and 70 th
transects were laid down adjacent to one another
along the 700-m length of the block Thus 1050
plots were established . The 700-m length of the
plot stretched roughly South to North and the 150m width from East to West. The habitat of each plot
with reference to topography, whether it is located
on a swampy site, a flat dry land, a slope or a ridge
was noted qualitatively. In each plot, all the trees
with DBH (Diameter at Breast Height) > 10 cm
were mapped, numbered with aluminum tags,
identified, and measured for DBH. Important
features of the forest were also recorded
qualitatively. The gaps within the plot were mapped
and a profile diagram of a 15 x 60 m2 subplot was
made as reported by Partomihardjo (1987).
Voucher specimens or fallen leaves (if a leafy twig
was not accessible) from each tree was collected
for identification at the Herbarium Bogoriense,
Bogor. The authority of botanical names of plants
in the plot followed Whitmore et al. (1989, 1990),
Keßler & Sidiyasa (1994) and Keßler et al. (2000)
The inventory was carried out between 1979 and
1981.
RESULTS AND DISCUSSION
Floristic characteristics and diversity
The results of the inventory of trees with DBH
> 10 cm showed that 553 species of 192 genera in
62 families, represented by 5847 individuals, with
the total basal area of 350.01 m2 (Table 1) occurred
in the 10.5 hectare plot. Of 550 species recorded,
we were able to name 425 species. Appendix 1
lists all species of trees with DBH > 10 cm by
family and reports absolute densities, relative
densities, frequencies, relative frequencies, basal
areas, relative basal areas and Importance Values
(IV). These parameters were calculated following
the standard procedure as discussed by MuellerDombois & Ellenberg (1974). The Total Species
Importance Values for a Family (TSIVF) indicates
the family importance value based on the sum of
IVs of all species in a family (Kartawinata et al.

STUDY AREA
Figure 1. The location of the study area at Wanariset Samboja, East Kalimantan
2004). It is evident that the forest had a high species
richness compared to other areas within the region.
No single species was dominant, instead dominance
was shared by several common species. The forest
was characterized by uneven species composition,
certain species were represented by large number
of individuals, while the majority of species were
represented by only a few individuals and often only
by one specimen. (Appendix 1).
The ten richest families in terms of number of
species are shown in Table 3. Ranked by number
of species present, Myrtaceae, Lauraceae,
Euphorbiaceae and Myristicaceae were the top four
families and Dipterocarpaceae occupied the 5th
ranking. In small plots in Borneo and Sumatra,
Lauraceae constitutes one of the top three most
common families (Whitmore & Sidiyasa 1986). In
the lowland forests of West Malesia, Euphorbiaceae
is by far the richest family (cf Abdulhadi 1991,
Davies & Becker 1996, Poore 1968, Riswan 1982,
Sist & Saridan1999, Suselo & Riswan 1987,
Whitmore 1986, Whitmore & Sidiyasa 1986). As
in the present study, Annonaceae, Burseraceae,
Dipterocarpaceae, Moraceae, Myristicaceae and
Rubiaceae are also in the top ten families ranked
by species richness in Borneo and Sumatra
(Kartawinata et al. 1981, Table 1). In terms of the
Total Sum of Important Values for Families
(TSIVF), the ten most important amilies show
different order. Dipterocarpaceae and Euphor-
2008]
KARTAWINATA et al: Wanariset dipterocarp forest structure
biaceae had the first and second highest values
(Table 3). The high value for Dipterocarpaceae
was attributed to the presence of large trees in the
plots (Annex 1). It is interesting to note that although
it contains only three species, Arecaceae had a
high TSIVF value, resulting from the high number
of individuals of Pholidocarpus majadum and
Borassodendron borneensis. In order to determine
whether the 550 species recorded in the 10.5-ha
plot represent the total number of species in the
area studied, a species-area curve was constructed
(Figure 2). The 1050 subplots of 10x10 m each
were examined to determine the number of
additional species recorded each time a subplot was
305
added. A considerable number of additional and it
continued to rise steeply even up to 10.5 hectare.
There was a very slight indication of leveling off at
about five hectares. This implies that a minimum
area can not be determined for this forest. This is
similar to lowland tropical rain forests elsewhere in
Borneo and the Malay Peninsula as reported by
various authors (Kartawinata 2006, Kartawinata et
al. 1981; Sist & Saridan 1999, Riswan 1982;
Whitmore 1986; Wyatt-Smith 1966, etc.), but it is
less dramatic compared to lowland forests of
Sulawesi (Kartawinata 2005; Whitmore & Sidiyasa
1986).

The forest of the present study is the second
most species rich in East Kalimantan after that in
Malinau, which constitutes the richest forest in
Indonesia (Kartawinata 2005). It can be seen from
Table 2 that if the number of species in one hectare
is extrapolated from the number in 10.5 ha plot, as
is shown also in the species-area curve (Figure 2,
and see also data of Abdulhadi et al. 1981), the
total species richness may be comparable to that of
Lempake (E. Kalimantan), Gunung Mulu (Sarawak)
Belalong and Andulau (Brunei), Bukit Lawang
(Riau), Bukit Lagong (Penisular Malaysia), and
higher than that of Aek Nauli and Ketambe
(Sumatra) and Toraut (Sulawesi). The species
richness was however lower than at Malinau 3 (East
Kalimantan), at least partly due to different plot
design.
The calculation of species frequencies was
based on the species data from the 70 transects, each
consisting of 15 subplots with the total area of 1500
m2. The majority of species had frequencies of less
than 50 % and species with frequencies greater
than 50 % are shown in Table 5. Interestingly,
among dipterocarps only Shorea ovalis and S.
laevis howed relatively high frequency, suggesting
that most dipterocarps species apparently grow in
clumps in this forest.
Simple ordination of the plots did not produce a
recognizable pattern of grouping the plots that
warrants the separation of swampy habitat on flat
lands from dry habitat on slopes and ridges. Field
observations concurred that the composition of the
forest on swampy sites was not much different from
that on dryland, although the following species were

Structure
The basal area of each tree recorded in the
plot was calculated. Appendix 1 shows these data
grouped by family, as well as for individual species,
along with other measures. The total basal area of
trees recorded in the plot was 350.01 m2, resulting
in a mean basal area of 33.33 m2/ha (Table 1). Ten
species with the highest basal areas are presented
in Table 4, in which Shorea laevis, Pholidocarpus
adum and Scaphium macropodum were the most
prominent. It was also evident that ten dipterocarp
species were prevalent, with a total basal area of
53.86 m2 (46.74%) As a whole, the dipterocarps
were the largest trees and dominated the forest with
25 species (representing 4.47% of the total species
richness) occupying a total basal area of 85.53 m2
(24.96 %). Most species had basal areas of less
than 1.0 m2 and only 71 species (12.90 %) had basal
areas greater than 1.0 m2, of which the highest basal
areas of 10-31 m2 were shared by three species
(Figure 3), i.,e. Shorea laevis, Pholidocarpus
majadum and Scaphium macropodum (Table 6).

Figure 4 shows the diameter class distribution
of trees with DBH > 10 cm in the 10.5-ha plot. The
data show more or less a typical size class
distribution of tropical undisturbed primary forest.
This reveals that 79.13% of the total trees had DBH
of less than 30 cm and only 20.87 % occurred in the
diameter class greater than 30 cm. The trees with
large DBH were mainly dipterocarps. Three largest
tree species were Shorea pauciflora ( DBH
=196.50 cm), Dipterocarpus cornutus (170.90 cm
) and Alstonia scholaris (170.0 cm). It is interesting
to note that a pioneer species, Anthocephalus
cadamba, developed well in this forest, where trees
were distributed in all diameter classes and reached
a maximum DBH of 128 cm. In contrast, Alstonia
scholaris, another pioneer species, demonstrated a
disjunct size distribution (Table 7)

disjunct size distribution (Table 7) with only two
large individuals of DBH 140 cm and 170 cm
(Appendix 1). A. cadamba is a light-demanding
species (Whitmore 1986) and, in this study, had a
large number of individuals with big diameters and
a low number of small individuals. This pattern
contrasts that of shade-demanding species, such as
Dipterocarpus cornutus, which had a higher
number of individuals of small sizes (Figure 5). Other
secondary forest species present in a relatively high
number of individuals in the plot are shown in Table
7, but none were as large as A. cadamba and
Alstonia scholaris. These species appeared to
occur on sites previously occupied by gaps. An
earlier study on this plot (Partomihardjo et al. 1987)
(Figure 6) reported that gaps covered a total area
of 17, 399 m2 (16.6 % of the canopy) and gap
formation was estimated to be 1,187 m2 (1.05 % of
the canopy opening annually) and the recovery rate
was about 16 years. Meanwhile, a man-made gap
of 0.5 ha in a lowland dipterocarp forest at Lempake,
about 100 km north east of Wanariset Samboja
(Riswan 1982; Riswan & Kartawinata 1989) was
immediately occupied by secondary forest species
after clearing. The primary forest species arrived
later and achieved a 50% proportion of all species
after 18 months. The primary forest arrivals included
dipterocarps, Hopea rudiformis, Shorea parvifolia
and Shorea leprosula, which were present also in
the present study (Appendix 1) and have been
reported to behave like pioneer species (Riswan
1982; Riswan & Kartawinata 1989, 1991).
Furthermore, in a 35 year old 0.8-ha gap at Lempake
the large trees were dominated by secondary forest
species, primarily Macaranga spp. (Riswan 1982;
Riswan &Kartawinata 1988a).
