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.

Pulau Rambut (± 56ha) is one of the islands of the Pulau Seribu group. It is a coral island covered by disturbed forest and secondary growth at the center, and mangrove forest at its periphery. A study in a 290 x 10 m transect running south to north across the mangrove forest shows a distinct zonation as follows : the Scyphiphora hydrophyllacea - Lumnitzera racemosa community on coral flat with patchy shallow soils on the interior, the Rhizophora mucronata community on relatively deep soil overlaying coral formation, and the R. mucronata - R. stylosa community on periodically submerged coral flat. Profile diagrams established along the transect show structural changes also. The R. mucronata forest is the most developed community and appears to be the most prevalent. R. stylosa forms the pioneer species on this island.

The Peucang Island is situated just off westernmost tip of West Java and is a portion of the Ujung Kulon Nature Reserve.It covers a total area of 450 hectares,comprising the level land and a ridge in the central portion with the highest point of about 30 m above sea level.Geologically this island is composed of Tertiary materials and alluvial materials on southern and eastern coastal areas (Verbeek and Fennema 1896).From the southeastern shore towards the hills, there are three types of soil, i.e. the sandy regosols, the tuffaceous over sandy regosols and the latosolized tuffaceous regosols over podsolized grumusols (Soerianegara 1969).

The Restored Forest (RF) in Bodogol, Gunung Gede Pangrango National Park (GGPNP) is located in the degraded lowland forest area. The Bodogol RF constituted the area of the ecosystem restoration program, where the initial tree planting was carried out by Mrs. Megawati Soekarnoputri the 5th President of the Republic of Indonesia. In that restored forest area, a study was conducted by establishing one hektare plots. We recorded 26 tree species and 16 families, including 14 tree species that were used in the restoration, four cultivated species, and eight species that naturally enter the site as new arrival (recruitment). The total basal area was 7.47 m2/Ha and tree density was 256 trees/Ha. The mean diameter growth was 1.78 cm/year, and the highest diameter growth was Hibiscus tilliaceus (2.42 cm/year). The mean total height growth was 0.52 m/year, and the highest was Paraserianthes falcataria (0.85 m/year). The density of Toona sureni was very high (61 trees/Ha) and in the future it ay dominate the forest will, therefore other tree species native to Mt. Gede-Pangrango should be planted to enrich the present restored forest so as to encourage the development of mixed lowland or montane forests similar to the original climax forests with high species diversity. Structurally, about 50 % of the RF has been achieved, but species composition still needs further enrichment either by active intervention of planting native TNGGP species if deemed necessary or by allowing succession to take place naturally, although it will take a very long time.
