HERIYANTO, N. M., SAMSOEDIN, I. & KARTAWINATA, K. 2018. Tree species diversity, structural characteristics and carbon stock in a one-hectare plot of the protection forest area in West Lampung Regency, Indonesia. Reinwardtia 18(1): 1‒18. — A study of species composition, structure and carbon stock in the lower montane forest in the Register 45B of the protection forest area in the Tri Budi Syukur District, Kebun Tebu Village, West Lampung Regency, Lampung Province was conducted in September 2016. The objective of the study was to undertake quantified measurements of floristic composition and structure of and carbon storage in the lower montane forest at 965 m asl in the protection forest area. A one hectare plot (100 m × 100 m) was established randomly. The plot was further divided into 25 subplots of 20 m × 20 m each to record trees. Quadrats of 5 m × 5 m for saplings and subquadrats of 2 m × 2 m for seedlings were nested in the tree subplots. We recorded 247 trees with diameter at breast height ≥ 10 cm representing 25 species and 19 families, with a total basal area of 59.14 m2. Overall including seedlings and saplings we recorded 31 species. The species richness was very low due to disturbances, and was the lowest compared to that of other forests in Sumatra, Kalimantan and Java. The dominant species in terms of importance values (IV) were Litsea cf. fulva (IV=77.02), Lithocarpus reinwardtii (IV=45.21) and Altingia excelsa (IV=26.95). Dominant species in seedling and sapling stages were Polyalthia lateriflora (IV=27.54) and Memecylon multiflorum (IV=41.58). Biomass and carbon stock of trees with DBH ≥ 10 cm was 50.87 ton/ha and 25.43 ton C/ha, respectively. Regeneration was poor. Structurally and floristically the forest was a developing disturbed forest and the composition will remain unchanged in many years to come. The successions leading to terminal communities similar to the original conditions would be very slow and should be assisted and enhanced by applying ecological restoration through planting tree species native to the site.

Reinwardtia 18(1): 61‒67. ‒‒ The new Hoya species from Sumatra, Hoya decipulae S.Rahayu & Astuti is here described and illustrated. It is an epiphytic shrub, thin-leaved with white flowers, similar to those of H. papaschonii Rodda, but differs in corolla and corona form. Its corolla has a unique characteristic of forming a “cage” before fully opening, as a result of the attachment of the five corolla tips which are free at the centre. The corona does not have interstaminal lobes as in Hoya papaschonii. Its corona resembles that of H. multiflora Blume and H. irisae Ferreras, Kloppenburg & Tandang from the centre to the tip but differs at the base.

ALHAMD, L. 2018. Ecological study of the arrowroot (Tacca leontopetaloides (L.) Kuntze) at Karimunjawa National Park, Central Java. Reinwardtia 17(2): 87–96. — An ecological study of arrowroot (Tacca leontopetaloides (L.) Kuntze) at Karimunjawa National Park (Karimunjawa NP), Central Java, was conducted at six islands, namely Kumbang, Nyamuk, Katang, Seruni, Cendikia and Sintok islands. A sampling plot of 10 × 50 m2 was established on each island. The results showed that the arrowroot population in Katang island was greater than those of other islands, with a density of 0.74 m-2, a frequency of 0.8 and an abundance of 23.1. The arrowroot density of all samplings ranged from 137 to 370 per 0.05 ha. The occurrence of 30 species surrounding arrowroot was observed and only five species, Sida acuta (Chi-square count (cs)>Chi-square table cs=5.71, P<0.05) and Scaevola taccada (cs=7.94, P<0.01) in Kumbang island, Imperata cylindrica (cs=18.81, P<0.01) in Nyamuk island, Morinda citrifolia (cs=9.47, P<0.01) in Sintok island, and Carica papaya (cs=3.95, P<0.05) in Cendikia island, had significant associations with arrowroot. For habitat characteristics, soil textures were dominated by sandy types ranging from 90 to 95%, whilst other soil properties such as pH, N, P, K, Mg and CEC did not significantly affect the presence of arrowroot.

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.

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.","PeriodicalId":52340,"journal":{"name":"Reinwardtia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47276864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POWLING, A. 2018. An assessment of present plant diversity on the Natewa Peninsula, Vanua Levu, Fiji. Reinwardtia 17(2): 125‒132. ‒‒ The Natewa Peninsula, part of the Fijian island of Vanua Levu, is naturally afforested but the forests have been extensively logged in the last 50 years. It is now planned to protect some of the forests from further logging by incorporating them into a National Park. A survey of plant species in the regenerating forests and surrounding land on the Peninsula was performed to assess the taxonomic and ecological diversity of the trees and shrubs, including figs and palms, and also the orchids presently to be found on the Peninsula. The degree of invasion by introduced plant species was also assessed. Of 67 tree and shrub species it was found that 17 were endemic to the Fijian islands, 40 others were indigenous and ten were introduced. The normal habitats of these species included dense, open and secondary forest, showing that trees with a range of ecological characteristics were still present. Endemic and indigenous species of both figs and palms were found, and also terrestrial and epiphytic orchids. No severe infestations of introduced species were observed. It is concluded that the forests of the Peninsula are of sufficient conservation value to justify National Park status.
