Information on tree community structure and composition is needed in forest management and restoration. These data can be obtained using a permanent plot for studying forest dynamics, including species-specific characteristics. These characteristics are useful in the identification of native species for commercial and restoration purposes. This study aimed to describe the tree community structure and composition of a one-hectare permanent plot in the montane zone of Mount Kerinci. Data collection was conducted from July to August 2016 on Mount Kerinci, Jambi. A plot was established at 2,182-2,258 m above sea level and subdivided into 100 subplots. All trees ≥ 10 cm DBH were tagged and measured. Twenty-eight species, 18 genera, 20 families, 570 individuals and Shannon index 2.89 were identified. Most of the potential species richness was covered on the research site. Syzygium lineatum was the species with the highest importance value and Myrtaceae had the highest family importance level. The study area was dominated by slow growing species that characterize primary forests. The population structure indicated a good capacity of forest regeneration, while the vertical structure formed a stratification consisting of three strata. The dominant large trees and 5 hyperdominant trees according to total biomass contribution were identified. These species are an important priority in forest management and restoration.

Abstract. Pratama MF, Dwiartama A, Rosleine D, Abdulharis R, Irsyam ASD. 2019. Documentation of Underutilized Fruit Trees (UFTs) across indigenous communities in West Java, Indonesia. Biodiversitas 20: 2603-2611. Fruit as a source of food has been mostly underrated, while in fact play a role in providing nutritional security as well as contributing to the integrity of local ecosystems. The declining significance of local indigenous fruits, often referred to as underutilized fruits, in rural populations may have an unprecedented consequence to the availability of high-quality resources for the wider society. This article, therefore, sees this importance by documenting the existence of underutilized fruit-trees across indigenous communities, often acknowledged to be the chaperones of local biodiversity. Using a combined method of interviews, exploratory observation and vegetation analysis in seven indigenous communities in West Java Province, this study investigated the role and position of fruit-tree species in their ecological landscapes and communities' knowledge systems. The article documents 75 fruit tree species, 38 out of which are categorized as underutilized. The proportion of this group of species to the total fruit tree species varied between 0 to 45%. Further analysis found that the underutilized fruit trees were far smaller in abundance compared to commercial timber, fruit, and other trees. We conclude that efforts to uplift the conservation value of these fruit-trees can begin via promotion and market development by multiple stakeholders.

Begonia holosericeoides (female flower and habit) (Begoniaceae; Ardi et al.); 2. : 85 -99. -Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarify vegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 × 10 m 2 in abandoned plantation and 11 of 20 × 20 m 2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swietenia macrophylla -Agathis dammara community in abandoned plantation where had a land use history of clear felling. Maesopsis eminii -Cyathea spp. community had a history of severe human disturbance. Fagaceae -Schima wallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery. . Pengaruh pemanfaatan lahan pada masa lalu terhadap rehabilitasi hutan alam di koridor Taman Nasional Gunung Halimun Salak, Jawa Barat Indonesia. Reinwardtia 14(1): 85 -99. -Koridor Taman Nasional Gunung Halimun Salak mengalami degradasi dan fragmentasi habitat yang cukup serius akibat aktivitas manusia. Sebanyak 22 plot (11 plot berukuran 10 × 10 m 2 di bekas hutan tanaman dan 11 plot berukuran 20 × 20 m 2 di hutan sekunder) disebar untuk menganalisa struktur vegetasi dan melihat proses pemulihan lahan hutan yang dihubungkan dengan sejarah penggunaan lahan yang berbeda-beda di kawasan ini. DCA (Detrended correspondence analysis) mengelompokkan tiga tipe komunitas yang ditemui di kawasan koridor, yaitu komunitas Swietenia macrophylla -Agathis dammara di lahan bekas hutan tanaman, Maesopsis eminii -Cyathea spp. di hutan yang sangat terganggu, dan Fagaceae -Schima wallichii di hutan sekunder yang mengalami sedikit gangguan. Jenis-jenis tumbuhan yang toleran terhadap cahaya, gulma, rumput dan paku Dicranopteris linearis mendominasi lantai hutan tanaman yang telah ditinggalkan, namun beberapa tumbuhan eksotis yang dapat mengancam keanekaragaman hayati ditemukan di hutan sekunder yang terganggu. Sisa hutan alami berada di lokasi yang jauh dengan pemukiman penduduk dan masih didominasi oleh tumbuhan asli hutan pegunungan. Berdasarkan hasil penelitian tersebut, rehabilitasi hutan di kawasan yang sangat rusak sebaiknya dibantu oleh manusia dengan menanam jenis-jenis tumbuhan asli untuk menghindari masuknya tumbuhan invasif, sehingga mampu mempercepat proses pemulihan hutan.Kata kunci: Taman Nasional Gunung Halimun Salak, pemanfaatan lahan, rehabilitasi hutan tro...
