 Mount Merapi National Park (MMNP) is a natural con-servation area with the main function of preserving the diversity of plants, animals and their ecosystems. In 2010, Mount Merapi suffered a large eruption which caused damage to the forest ecosystem inside. One of the locations that suffered severe damage was at Cangkrin-gan Resort. After the eruption, the affected vegetation began to grow again. The purpose of this study is to monitor and determine the di-versity of secondary forest plants in the MMNP area. The method used was a method of path and use a point-intercept transect as the sam-pling unit. The results showed that after the eruption, the Acacia de-curens dominated at each level starting from sapling, poles and trees. Based on the results of the study showed that the eruption of Mount Merapi that occurred in 2010 resulted in a change in vegetation struc-ture in the area with the Shannon-Weiner diversity index which is still low, amounting to 1.86 for seedling, 1.32 for the sapling and 0.22 for poles. At the tree level 100% is still dominated by Acacia decurens.

Lore Lindu National Park in Central Sulawesi is one of the protected areas. Although it is protected, many of its areas are experiencing pressure and disruption by human activities. The purpose of this research was to know the relationship between farmers’ income and land cover change at Lore Lindu National Park. The research method was a participatory survey. Variables of incomes were sourced from farming and outside farming (forests). Data of land cover change were obtained using imagery in 2012, 2014 and 2016. The result of research is the average of farming income of IDR 1,387,077 (cocoa farming) and non-farm income of IDR 854,819 (forest honey, resin). In the last five years (2012-2016), the primary forest area decreased by 902.37 ha, while the secondary forest has shown an increase of 2,233.61 ha. The trend of land cover change was drastic, with change in the secondary dry land forest area from 6.9 ha (in 2012) to 2,240.5 ha (in 2016). The increased secondary forest area and the secondary forests have been converted into agricultural land and mixed gardens.

SAMBAS, E. N., KUSMANA, C., PRASETYO, L. B. & PARTOMIHARDJO, T. 2018. Vegetation analysis and population structure of plants at Mount Endut forested area, Gunung Halimun Salak National Park, Banten, Java,Indonesia. Reinwardtia 17 (1): 39–53. — Study of vegetation structure and species composition at Mount Endut was carried out by using transect and plot methods. Data of trees, saplings and seedlings were enumerated from four transects measuring 10 m × 2,000 m in four directions of slopes i.e. North, South, East and West. In total there were 180 species of trees and saplings belonging to 105 genera and 51 families. Tree density and basal area indicate the variation and the differences in each of the sampling locations. Density of saplings and abundance of seedlings tend to be low in locations with high density and basal areas at tree level. Tree species having higher Importance Value were Castanopsis acuminatissima, Schima wallichii, C. argentea, Quercus gemelliflora, and Altingia excelsa. Castanopsis acuminatissima, Garcinia rostrata, S. wallichii, Symplocos cochinchinensis, and Prunus arborea were saplings which had highest density, while Ophiorrhiza marginata, Cyathea contaminans, Pinanga coronata,C. acuminatissima, and G. rostrata were the most abundant listed seedlings at the study site. At least 27 tree species (21.91%) were recorded as relatively rare (presence represented by only 1–2 individuals), thus requiring special attention in the management of the area.

<p><em>Abstrak</em><strong>- </strong><strong><em>Acacia decurrens</em></strong><strong>, adalah jenis asing yang mulai menjadi perhatian sejak dominasinya di lahan bekas erupsi Gunung Merapi tahun 2006. Tujuan dari kegiatan studi ini adalah untuk mendeskripsikan secara kuantitatif Ekologi <em>Acacia decurrens</em>, hubungannya dengan beberapa faktor lingkungan serta potensi keinvasifannya jika dikorelasikan dengan <em>diversity index</em>. Analisis vegetasi dilakukan di empat wilayah Taman Nasional Gunung Merapi (TNGM) yaitu Kalikining, Kaliadem, Plawangan dan Pranajiwa. Ordinasi menggunakan metode <em>Non metric multidimensional scaling</em> (NMDS) serta <em>Canonical Corespondence</em> (CCA) serta korelasi <em>bivariate</em> Spearman dilakukan dalam analisis data. Hasil analisis NMDS (2D stress = 0,14) memperlihatkan bahwa daerah terbuka akibat erupsi di Kaliadem kini didominasi oleh jenis <em>A. decurrens</em>. Hasil analisis juga menunjukkan adanya korelasi negatif yang signifikan (Spearman’s rho = 0,6) antara kelimpahan jenis <em>A. decurrens</em> dengan tingkat keanekaragaman jenis di dalam lokasi sampling. Dari hasil CCA, <em>A. decurrens</em>, pada tahap semai, nampak hidup berdampingan dengan jenis groundcover lainnya seperti <em>Alangium javanicum</em>, dan Araliaceae. Namun pada fase pohonnya, jenis ini cenderung membentuk tegakan murni. <em>Acacia decurrens</em> tingkat pohon nampaknya lebih memilih sites dengan tingkat pH yang lebih rendah sedangkan <em>A. decurrens</em> tingkat semai lebih banyak ditemui pada site-site ber pH lebih tinggi. <em>A. decurrens</em> berpotensi menjadi gulma di TNGM.</strong></p><p><em>Abstract - </em><strong>Acacia decurrens, is an alien plant species that has begun to be a concern since its dominance in the former eruption of Mount Merapi in 2006. The purpose of this study is to describe quantitatively the Ecology of Acacia decurrens, its relation to several environmental factors and their invasive potential if correlated with diversity index. Vegetation analysis was carried out in four areas of Mount Merapi National Park, namely Kalikining, Kaliadem, Plawangan and Pranajiwa. Ordination using Non metric multidimensional scaling (NMDS) and Canonical Correspondence (CCA) methods and Spearman bivariate correlations were carried out in data analysis. NMDS analysis (2D stress = 0.14) shows that open areas due to eruptions in Kaliadem are now dominated by A. decurrens. The results of the analysis also showed a significant negative correlation (Spearman’s rho = 0.6) between the abundance of A. decurrens species and the level of species diversity in the sampling location. From the results of CCA, A. decurrens, at the seedling stage, appears to coexist with other types of ground cover such as Alangium javanicum, and Araliaceae. But in the tree phase, this type tends to form pure stands and only occasionally appear alive can it coexist with other Fabaceae species such as Albizia lopantha. Acacia decurrens tree level seems to prefer sites with lower pH levels while A. decurrens seedling levels are more common at higher pH sites. A. decurrens have the potential to become weeds in the Mount Merapi National Park.</strong></p><p><strong><em>Keywords</em></strong>-<em>Autekologi, Faktor Lingkungan,</em><em> IAS,</em><em> Risk Assesment</em></p>

The existence of cendrawasih (Paradisaea minor jobiensis Rothschild 1897) has been endangered due to destruction its habitats and wild hunting, hence conservation of its habitats is urgently needed. The objective of this study was to determine the availability of vegetation materials for creating the nests as an effort for the conservation of P. minor jobiensis in Imboriawi Forest, Barawai, Yapen Islands, Papua. Data were collected using the method of line compartment. Vegetation at seedling, sapling, pole and tree levels were measured and analyzed to determine the availability of plant species as the materials for creating bird nest. The results of vegetation analysis revealed 60 species at seedling level, 43 species at sapling level, 68 species at pole level, and 74 species at tree level with high diversity index values (H’) of 3.68, 3,32, 3,87, and 3,87 for seedling, sapling, pole, and tree levels, respectively. The results also revealed that vegetation used as a materials of nest of P. minor jobiensis in Imbowiari Forest is Bidens spilosa, Macaranga mappa, Timonius timon and Ficus septica. The four species at seedling, sapling, poles, and tree levels have low diversity index values (H’= 1) but can be used as indicators of making a nest in a sustainable way. Keywords: bird nest, conservation, Paradisaea minor jobiensis, vegetation analysis

<p>Sago (<em>Metroxylon sagu</em> Rottb) in Maluku grow naturally to form sago forest ecosystem. Hymenoptera in the sago forest ecosystem has not been studied. This study aims to examine the diversity of Hymenopterous parasitoids in sago forests in Maluku. The research was conducted in Ariate, Eti, Waisamu, Rutong, Tawiri, and Tulehu in September 2015 - October 2016. Hymenopterous parasitoids were collected through swing nets, light traps, yellow pan traps, and pitfall traps. Results the abundance of hymenopterous parasitoids in six sago areas in Maluku was found to be 14 families and 32 species. The morphoses of morphospecies are 68 morphospecies of Sago Ariate forest 32 morphospecies, Eti 37 morphospecies, Waisamu 9 morphospecies, Rutong 11 morphospecies, Tawiri 19 morphospecies, and Tulehu 37 morphospecies. The high diversity index (2.18 - 3.55) per location, Morphospesies wealth of Tulehu is  higher than other location, while the individual abundance of Ariate is higher than other villages. The average relative abundance of Scelionidae, Scoliidae and Ichneumonidae families was higher by 26.46%, 15.95%, and 10.89%, respectively. There are three families with high morphospecies and individual abundance in each sago area ie Scoliidae in sago forest area of Ariate and Waesamu, Scelionidae on Rutang, Eti, and Tawiri sago wood area, while Eulophidae on sago Tulehu area. There are 12 unique species or species with only certain locations and none in other locations, each Ariate (2 species), Eti (2 species), and Tulehu (8 species).</p><p>ABSTRAK</p><p><br />Sagu (Metroxylon spp.) merupakan tanaman sosial, budaya dan ekonomi di Maluku dengan potensi hutan sagu cukup tersedia. Teridentifikasi gejala kerusakan empulur pati dan tajuk tanaman sagu akibat serangga. Kebijakan pengendalian hayati melalui pelepasan parasitoid dalam sistem aplikasi Pengendalian Hama Terpadu merupakan salah satu alternatif. Hymenoptera parasitoid pada ekosistem hutan sagu penting untuk dipelajari morfospesiesnya sebagai data dan informasi ilmiah dalam menunjang program pengembangan agens hayati dalam pengelolaan serangga herbivor tanaman sagu. Penelitian ini bertujuan untuk mengkaji keanekaragaman Hymenoptera parasitoid pada hutan sagu di Maluku. Dalam penelitian ini dipilih tiga lokasi di Pulau Ambon dan tiga lokasi di Pulau Seram, kemudian masing-masing lokasi dipilih tiga rumpun sagu contoh secara acak. Setiap rumpun sagu dalam lingkaran radius 5m dari pohon sagu utama seluas 100m2 dilakukan pengambilan serangga melalui jaring serangga, perangkap lubang, dan perangkap nampan kuning, sedangkan perangkap lampu dilakukan pada satu titik disetiap lokasi. Pengambilan serangga dilakukan pada musim kemarau dan hujan dibulan September 2015 – Oktober 2016. Hasil penelitian menunjukkan bahwa kelimpahan Hymenoptera parasitoid pada enam lokasi hutan sagu diperoleh sebanyak 14 famili dan 30 morfospesies. Kekayaan morfospesies disetiap lokasi berkisar antara 5-21 morfospesies, dengan proporsi koleksi serangga melalui penggunaan jaring serangga lebih tinggi. Indeks keanekaragaman tinggi (2.18 – 3.55) per lokasi, kelimpahan individu di Ariate dan kekayaan morfospesies di Tulehu masing-masing lebih tinggi dari lokasi lainnya. Rata-rata kelimpahan relatif famili Scelionidae, Scoliidae, dan Ichneumonidae masing-masing 26.46%, 15.95%, dan 10.89%. Terdapat 12 spesies unik masing-masing Ariate (dua spesies), Eti (dua spesies), dan Tulehu (delapan spesies). Scelionidae, Scoliidae, Ichneumonidae dan Eulophidae merupakan kelompok parasitoid telur-larva potensial yang terindikasi berasosiasi dengan serangga herbivor pada tanaman sagu dari ordo Coleoptera dan Orthoptera.</p><p> </p><p> </p>
