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. Reinwardtia  12 (5): 391–404.  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.

Abstract

SADILI, A. & KARTAWINATA, K. 2016. A study of the undergrowth vegetation of Sempu Island, East Java, Indonesia. Reinwardtia 15(1): 1 - 9. — 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 × 50 m, which was divided into 50 subplots of 1 m × 1 m each. Overall from the two plots we recorded 59 species, 57 genera and 39 families. Shannon-Wienner diversity indices (H’) 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. javanicum  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.

Abstract

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): 133‒154. ‒‒ 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 × 10 m each. We enumerated all trees with DBH ≥ 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-Wiener’s 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 (A–D). 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.
