Hutan Gambut Suaka Margasatwa Giam Siak Kecil Dan Hutan Gambut PT Arara Abadi – Popinsi Riau; Vegetasi Dan Kerusakannya

This study aims to determine state of plant vegetation stands within of damage level at the Giam Siak Kecil wildlife sanctuary (Tasik Betung area) and Conservation Forest PT Arara Abadi (Bukit Batu area) - Riau. Several plots of different vegetation types were used in this study. The number of plots develoved in Tasik Betung were 13 plots, while in Bukit Batu were 11 plots (50 x20 m). The plots were conducted for trees (10 x10 m) and belta (5 x 5 m). The two study sites were generally susceptible to interference, especially in Tasik Betung. The total number of trees and belta were recorded for 178 species, 91 genera and 43 families. The main trees species at Tasik Betung was dominated by Pandanus Artocarpus (IV=17,35%), while Bukit Batu was Gonystylus bancanus (IV=21,35%), The belta category at Tasik Betung was dominated by Gymnacanthera contracta (IV=19,31%), while in Bukit Batu was Mangifera parvifolia (IV=34,71%). Species protected of Endangered species found were Dillenia excelsa, Garcinia bancana, Shorea parvifolia, S. teysmaniana, S.uliginosa, Vatica rassak, and V. umbonata

Komunikasi Pendek* Studi Floristik Jenis-jenis Anggrek (Orchidaceae) Di Taman Nasional Gunung Halimun, Jawabarat

Lokasi Taman Nasional Gunung Halimun secara administratif termasuk dalam tiga wilayah Kabupaten, yaitu Bogor, Sukabumi dan Lebak.Kawasan ini diresmikan sebagai Taman Nasional pada tahun 1992 yang meliputi luasan 40.000 ha.(Anonim. 1999.Gunung Halimun National Park Mesh Map. Biodiversity Conservation Project. Bogor. 53 pp.). Taman Nasional Gunung Halimun terbagi dalam sembilan daerah kerja (Resort). Lima resort di antaranya, yaitu kawasan resort Citorek,Cikelat, Kabandungan, Cisangku dan Cigudeg telah dikunjungi dan diamati keragaman jenis anggreknya. Tujuan penelitian ini adalah untuk mengetahui keragaman jenis anggrek dan mengevaluasi status populasinya di alam

Opportunities and challenges for an Indonesian forest monitoring network

© 2019, INRA and Springer-Verlag France SAS, part of Springer Nature. Key message: Permanent sampling plots (PSPs) are a powerful and reliable methodology to help our understanding of the diversity and dynamics of tropical forests. Based on the current inventory of PSPs in Indonesia, there is high potential to establish a long-term collaborative forest monitoring network. Whilst there are challenges to initiating such a network, there are also innumerable benefits to help us understand and better conserve these exceptionally diverse ecosystems

Struktur Dan Komposisi Jenis Tumbuhan Herba Dan Semai Pada Habitat Satwa Herbivor Disuaka Marga S Atwa Cikepuh,sukabumi, Jawabarat [Structure and Composition of Herbaceous and Seedling Communities on the Herbivore Habitat Within Cikepuh Wildlife Sanctuary, Sukabumi, West Java]

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%
