Abstract. Cahyanto T, Efendi M, Ramdan DM. 2020. Structure and composition of trees in Mount Tilu Nature Reserve, West Java, Indonesia. Biodiversitas 21: 2674-2680. An understanding of the structure and composition of stands in a conservation area is needed to support sustainable management strategy. However, this information in the Mount Tilu Nature Reserve, Bandung District, West Java area is still lacking. This research was aimed to analyze the structure and composition of tree species in the block of Malagembol forest, Mt. Tilu NR. Data collection was carried out through vegetation analysis using sampling plot method with size of 10x100 m2 at three-level altitudes of 1530 m, 1745 m, and 1950 m asl. Observation parameters included species names, number of individuals, and diameter at breast height (dbh). Data were analyzed to determine the floristic composition, species structure based on their diameter class, relative basal area, diversity indices, and analysis of the importance of the main components of trees species through Principal Component Analysis (PCA). A total of 32 tree species from 23 families was found in the observation plots which was dominated by Fagaceae, Lauraceae, and Myrtaceae families. Some pioneer plants covered the gap in vegetation due to minor disturbance and residual damage in the past. Nonetheless, the dominance of stands with small diameters indicated good regeneration status following such disturbance. Based on these findings, we recommend protecting the vegetation in Mt. Tilu NR by limiting community activities that can disturb the forest.

In the municipality of Abomey-Calavi in the Department of the Atlantic in South Benin, home gardens constitute at least 35% of the families' monthly sources of food, fruit, poultry and pigs. 43 home gardens were visited and 30 were selected by reasoned choice for the survey itself. The objective of this study is to show the contribution of these home gardens to the food security of rural populations. The data concerned the size, floristic composition, phytogeographical distribution, the years of creation of home gardens, the various uses of plants, the incomes brought by plants such as bananas, palm trees, coconut trees and teak. Individual structured interviews were used to interview households. Indices of diversity such as Shannon-Wiener and Jaccard have made it possible to categorize these home gardens and to specify their biological richness. The size of these gardens ranges from 200 m2 to 8300 m2. The average percentage of species grown in home garden is 55% for their nutritional values, 29% for their medicinal values, 7% for the wood and energy needs of the populations. Half of the species found, have a wide geographical distribution. Income from these agrosystems sometimes cover partially or totally the children's school fees. This study has therefore shown the importance of home gardens in the municipality of Abomey-Calavi in a context of climate variability and increasingly pronounced demographic pressure on natural resources.

Sandalwood (Santalum album L) is one of tropical plant in Indonesia that possess high economic value. Natural distribution of sandalwood centered in arid area of Nusa Tenggara Timur province and now a days this plant was groupped as rare plant. Many activities of in situ conservation for sandalwood have been carried out at some locations but did not give satisfaction in result yet. Ex situ conservation with utilize conservation on farm system is new model of plant conservation that involved local people. System of conservation on farm for sandalwood plant be defined as cultivation of sandalwood in the field/garden and home garden with involved farmers or local people. This system is known 2 models are ABC model (Model Agroforestri Berbasis Cendana) and Home garden as model of conservation area. Both models that mention had been applied in Belu regency, Nusa TenggaraTimur province.This research proposed to study the growth of sandalwood in ABC Model in the field/garden and in home garden as model of conservation area and to know the system of conservation on farm for sandalwood in Belu regency, Nusa Tenggara Timur province. ABC model was applied in 2 locations at Dirun Village (altitude at1000 m above sea level) and Teun Village (altitude at 500 m above sea level), while home garden as model of conservation area was applied at Teun village only.The Result shown that the rate of sandalwood growth in ABC model at Dirunvillage from first to third year between 60-70 cm in height per year, while sandalwood growth from third to fourth year has happened decreasing about 25 cm. The rate of sandalwood growth in ABC model at Teun Village from first to second year about 70-77 cm in height. The rate of sandalwood growth in home garden during 6 month after planting time about 4 -5 cm in height. Number of seedling still alife during 2 years after planting time in ABC model at Teun Village about 72%, during 4 yaers after planting time in ABC model at Dirun Village about 79%. While sandalwood seedling still alife during 6 months in home garden as model of conservation area about 75%. High persentation of seedling still alife with optimum rate of sandalwood growth have been found in this research because presence involvement of localpeople.

The flora of the Rupestrian Savannah (Cerrado Rupestre) is composed of widely distributed species and endemic species from high altitude rocky outcrops. The aim of this study was to characterise the floristic composition, structure and diversity of fragments of Rupestrian Savannah in south-eastern Brazil and to examine the similarity with other rupestrian cerrado vegetations and with cerrado sensu stricto on profound soils. For this, phytosociological parameters, evenness and diversity were calculated and compared with other studies. The survey exhibited 72 species, 45 genera, 30 families and high floristic similarity with cerrado on profound soils. There were no indicator species of the Rupestrian Savannah, but there were typical species of rocky environments. The basal area was significantly larger in the profound soil cerrado in relationship to the Rupestrian Savannah and evenness was lower in the Rupestrian Savannah of this study compared to others. These variables reflect the lower exploration capacity of the root of rocky environments. The highest similarity between the Rupestrian Savannah and cerrado on profound soils refers to the canga ferruginous nature, which represents the limit of the tableland of cerrado on the edge of the plateaus, allowing greater sharing of flora.

We studied the floristic composition and structure of the logged-over peat swamp forest in the  PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been  set aside by the company.  In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect,  thus covering a sampled area of 1-ha.  The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness.  The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth.  Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high  (3.05)  Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46  %).  The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and  D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed  strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium  and based on this association combined  with high IVs, the two parameters of species  characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and  Gonystylus bancanus vulnerable, hence they should  be protected.

The vegetation of inland plains and hills of the Andrew’s Field and Tsaba-Tsaba Nature Reserve, Bredasdorp District, Western Cape was classified using TWINSPAN and Braun-Blanquet procedures. The resulting four plant communities and nine subcommunities were described and interpreted ecologically. The vegetation was sampled using 97 randomly stratified plots. The floristic composition, Braun-Blanquet cover-abundance of each species, and various environmental variables were recorded in each sample plot. The relationship between the vegetation units and the associated environmental gradients was confirmed by ordination, using the DECORANA computer program, applied to the floristic data set. The conservation priority of each vegetation unit was determined by taking the occurrence of Red Data List species, limestone endemic species and Cape Floristic Region endemic species into consideration. TTie distribution of the plant communities can mainly be ascribed to differences in the clay/sand content of the soil and the degree of exposure of the vegetation to the dominating winds (southeastern and northwestern) of the area.
