ABSTRACTSimeuleu island is located in the western part of Sumatera belonging to Aceh Province. Floristic and phytososiological information of vegetation in Simeuleu island is limited and not much study has been conducted, especialy trees species group (diameter ?10 cm). Two study plots were used: one hectare at Kuala Makmur forest and one ha at Alafan forest (100 m × 100 m). Density analisys at Kuala Makmur recorded 329 individuals/ha while at Alafan consisted of 377 individuals/ha (average of 353 individuals/ha). Total basal area at Kuala Makmur 29.48 m2/ha while at Alafan was 44.28 m2/ha (with an average of 36.88 m2/ha). The Shannon-Wiener diversity index (H?) at Kuala Makmur was 2.94 and at Alafan was 2.73 (whit an average H?of 2.84). The total canopy heights of the two study sites as were relatively similar consisting of four strata. Dominant species occurred at Kula Makmur was Shorea atrinervosa (Importance Value, IV=83.55%) and at Alafan was Dipterocarpus grandiflorus (IV=128.06%). Dominant familly at Kuala Makmur was Dipterocarpaceae and at Alafan was Ebenaceae. The distribution of dominant tree species at Kuala Makmur is less prevalent than at Alafan. Keywords: Simeuleu, Aceh, trees structure, species richness, lowland forest.

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, SouthÂ Kalimantan. This study used a plot of 10 m x 500 m (Â± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that thereÂ were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum asÂ the dominant species. The diversity index (Hâ) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on theÂ results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except forÂ A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, withÂ Saurauia nudiflora (Acthiniaceae) was the dominant host plant.

SADILI, A., KARTAWINATA, K., KARTONEGORO, A., SOEDJITO, H. & SUMADIJAYA, A. 2009. Structure and composition of subalpine summit habitats on Mt. Gede-Pangrango complex, Cibodas Biosphere Reserve, West Java, Indonesia. ReinwardtiaÂ Â 12 (5): 391â404.Â We undertook a phytosociological analysis of the subalpine herbaceous and shrubby vegetation at the Mandalawangi and Suryakencana meadows and the scrub at the Crater Side at the tops of Mt. Gede and Mt. Pangrango in the Cibodas Biosphere Reserve. We recorded 30 species of 18 families of saplings, shrubs, seedlings and herbs in 78 quadrats with a total area of 7,800 m2. Anaphalis javanica, a woody tall herb and long-lived pioneer was the dominant species in the sapling and shrub stratum, while Isachne pangerangensis, Tripogon exiguus and Carex verticillata were prevalent in the seedling and herb stratum at Mandalawangi and Suryakencana. Stunted shrub is Vaccinium varingaeifolium, dominant in the Crater Side scrub. Based on the importance values, the Mandalawangi meadow may be designated as the Anaphalis javanica-Isachne pangerangensis community type, the Suryakencana meadow as Anaphalis javanica-Tripogon exiguus community type and the Crater Side scrub as Vaccinium varingiaefolium-Seliguea feei community type. The similarity indices between Mandalawangi and Suryakencana community types were very high (>75 %) while those between the Crater Side and Mandalawangi and the Crater Side and Suryakencana were very low (<10 %). Poor soil conditions and fire seem responsible for the perpetual existence of A. javanica.

SADILI, A. & KARTAWINATA, K. 2016. A study of the undergrowth vegetation of Sempu Island, East Java, Indonesia. Reinwardtia 15(1): 1 - 9. â A study of forest floor vegetation in coastal forest (site 1) and inland lowland forest (site 2) was carried out at the Sempu Island Nature Reserve, Malang Regency, East Java. The objective of the study is to obtain data on plant species diversity, species composition and structure of the forest floor vegetation. In each site the vegetation was sampled with a plot of 1 m Ã 50 m, which was divided into 50 subplots of 1 m Ã 1 m each. Overall from the two plots we recorded 59 species, 57 genera and 39 families. Shannon-Wienner diversity indices (Hâ) were relatively high. i.e., 4.47 in Plot 1 and 3.2 in Plot 2, with a mean of 3.84. The number of the seedlings of shrubs and trees was greater than that of the herbaceous species. The families having the highest number of species were Euphorbiaceae (6 species) and Fabaceae (5 species). Based on dominant species the vegetation in Plot 1 was designated as Scleria lithosperma-Asystasia nemorum community type, while in Plot 2 Pterospermum javanicum-Knema sp. community type. The similarity index between these community types was only 18%. Only P. javanicumÂ showed a good regeneration and the regeneration of other species in the two community types was poor, indicating unclear floristic changes in the forest of the Sempu Island.

Galunggung Mountain forest area in West Java of post eruption 1982 may served as a natural laboratory for studying plant development and plant growth, including pine trees. Pine trees that were planted by Perhutani at Galunggung had high prospect although they were planted at degraded areas and poor nutrient. Experimental plots were set up in two different locations at Mount Galunggung. Trunk diameter, tree height, total height, soil humidity and soil pH was measured for all pine trees inside the plot at each subplot. All measured parameters resulted in varied values with varied deviation standard. Measurement of trunk diameter, branches height and total height of pine trees in Mount Galunggung suggested that their growth rate was slow and no significant correlation among them.

The research was conducted to study the structure and composition of herbaceous and seedling communities (understorey species)occurred on herbivore habitat within Cikepuh wildlife sanctuary. A series of 25 plots of 1 m x 1 m each with an interval of 5 m were used to establish a species-area relationship. The proportion (percentage) of canopy (leaf) coverage of each species occurred within the sampling plots to the sampled soil surface area was measured. A total of 54 species belonging to 47 genera and 29 families occurred in the 25 plots develoved, with the species diversity index (value) of 2.09 using the Shannon Wiener formula. Nine species were categorized as herbaceous plants (16.67 %) while the other 45 species were categorized as seedlings (83.33 %). The average density measured was 39 individuals/m or c. 386.400 individuals/ha. The most dominant family is Euphorbiaceae (possessing 5 diffrent species) while the most dominant species is Urochloa subquadripara (Poaceae) with and importance value of 96.08%.

First year re-monitoring conducted in 2009 through measuring the entire individuals that have been given numbersand giving new numbers to individuals with stem diameter more than 5 cm. The result of re-monitoring indicatesthat the numbers of populations and species increased, but not significant. Mortality rate observed 7 individualsper hectare (about 1.20 %); whereas natality rate observed 25 individuals per hectare (about 2.52 %), which isregarded as low. Basal area observed in 2008 was approximately 26.55 m2 per hectare and it increased to about27.34 m2 per hectare in 2009. Total number of individuals in 2009 was 595 individuals from 119 species, 86genera, and 44 families with diversity index of 3.60 (HÃ¢â¬â¢). Elaeocarpus petiolatus (Elaeocarpaceae) and Planchoniavalida (Sapotaceae) are new additions. Altingia excelsa is still the dominant species.Keywords: Forest dynamics, rasamala permanent plots, Bodogol, GPNP

ADILI, A., KARTAWINATA, K., SOEDJITO, H. & SAMBAS, E. N. 2018. Tree species diversity in a pristine montane forest previously untouched by human activities in Foja Mountains, Papua, Indonesia. Reinwardtia 17(2): 133â154. ââ A study on structure and composition of the pristine montane forest previously untouched by human activities was conducted at the Foja Mountains in November 2008. We established a one-hectare plot divided into 100 subplots of 10 m Ã 10 m each. We enumerated all trees with DBH â¥ 10 cm which diameters were measured, heights were estimated and habitats were noted. We recorded 59 species, 42 genera and 27 families, comprising 693 trees with the total basal area (BA) of 41.35 m2/ha. The forest had lower species richness compared to those of lowland forests in Kalimantan, and Sumatra and montane forests in West Java. The Shannon-Wienerâs diversity index was 3.22. Nothofagus rubra (Importance Value, IV=47.89%) and Parinari corymbosa (IV=40.3%) were the dominant species, constituting the basis for designating the forest as the Nothofagus rubra - Parinari corymbosa association. To date, the dominance of N. rubra is unique to the Foja Mountains, as elsewhere in Papua the montane forests were dominated by N. pullei or other species. The species-area curve indicated a minimal area of 5000 m2. On the family level Fagaceae (IV=53.23%), Chrysobalanaceae (IV=40.53%) and Myristicaceae (IV=26.43%) were dominant. Verti-cally the forest consisted of four strata (AâD). In each stratum Nothofagus rubra, Platea latifolia, Parinari corymbosa and Myristica hollrungii were dominant. The diameter class distribution of Nothofagus rubra, Parinari corymbosa and Platea latifolia led us to assume that these species were regenerating well.
