Abstract: The understory is an important component in the tropical forests, particularly to contribute to ecosystem services function and playing on succession. However, the study on their existence related to the zonation effect in an ex-situ conservation is still lacking. This study aimed to compare the structure and composition of the understory in the two blocks of Ir. Djuanda Forest Park, Bandung. Data collection was carried out through vegetation analysis using plot methods (sampling plots). A total of 40 sampling plots of 5m x 5m were made in two observation blocks. The Importance Value Index (IVI) for each species was calculated based on their relative density and relative frequency. Seventy-three species of understory from 38 families were found in the observation plots, dominated by Araceae and Moraceae families. The composition of the protected block has higher species richness than the utilization block due to the differences in microclimates conditions. Calliandra calothyrsus, known as an invasive species, has the highest IVI indicating high adaptability to open habitats in the utilization block, while two native species, Plectranthus sp. and Chlorathus elatior, dominate in the protection block. Based on these findings, we showed that forest zonation drives exotic and native species abundance in the ex situ conservation area.Abstrak: Tumbuhan bawah merupakan salah satu komponen penting dalam vegetasi hutan tropis, terutama dalam pelayanan ekosistem dan berperan dalam proses suksesi. Namun, penelitian mengenai keberadaannya dikaitkan dengan pengaruh zonasi di kawasan konservasi secara ex situ masih jarang. Tujuan penelitian ini untuk membandingkan struktur dan komposisi tumbuhan bawah pada dua blok yang berbeda di kawasan Taman Hutan Raya Ir. Djuanda, Bandung. Pengambilan sampel menggunakan analisis vegetasi dengan metode plot (petak contoh). Sebanyak 40 plot kecil berukuran 5mx5m di kedua blok pengamatan. Indeks nilai penting (INP) setiap jenis dihitung berdasarkan kerapatan relatif dan frekuensi relatifnya. Sebanyak 73 jenis dalam 38 suku tumbuhan didata di dalam pengamatan, yang didominasi dari suku Araceae dan Moraceae. Berdasarkan jumlah jenis tumbuhan penyusunnya, blok perlindungan memiliki jenis yang lebih banyak dibandingkan dengan blok pemanfaatan berkaitan dengan berkaitan dengan perbedaan kondisi iklim mikro di kedua blok tersebut. Jenis Calliandra calothyrsus, dikenal sebagai tumbuhan invasif, memiliki nilai INP tertinggi menunjukkan kemampuan adaptasi yang tinggi pada habitat terbuka di blok pemanfaatan, sedangkan tumbuhan asli pegunungan jawa, Plectranthus sp. dan Chloranthus elatior mendominasi pada blok perlindungan. Berdasarkan hasil temuan ini, kita menyarankan bahwa zonasi mempengaruhi kelimpahan tumbuhan eksotik dan asli di kawasan konservasi tumbuhan secara eksitu.

One of the problems encountered by the Bukit Barisan Selatan National Park (TNBBS) is the presence of invasive alien species. Invasive alien species are plants that grow outside their natural distribution and have the ability to cover the area; hence it could suppress the growth of the other plants. The presence of invasive alien species in the national park has been widely reported to cause negative impacts on the ecosystem, local biodiversity, socio-economic, and human health in the vicinity. This study was carried out in the rehabilitation zone of the Sukaraja Atas Resort of TNBBS that had shifted into open land. This study aimed to determine the species and dominance of invasive alien species that exist. The sampling method was used by laying plots consisted of the combination of the line and multiple plot methods with a total plot of 25 plots. Data analysis was performed by selecting invasive alien species observed based related-literature, while the dominance of invasive alien species was calculated by the importance value index (IVI). The results identified 121 species, of which 29 species or 35% of them were classified as invasive alien, which originating from 19 families. Three invasive alien species become the most dominating, namely: Clidemia hirta with an IVI of 22.61, Imperata cylindrica with an IVI of 18.03, and Calliandra calothyrsus with an IVI 17.96. The environmental conditions and species characteristics supported the three invasive alien species domination; hence it inhibited the growth of native species. Keywords:  Bukit Barisan Selatan National Park, invasive alien species, rehabilitation zone

Abstract Urban forests are responsible for a lot of benefits, and can be used as a tool to ex-situ conservation of native species. Our study investigated a public urban forest aiming to provide subside to management projects in order to allow the accurate fulfillment of social, aesthetic and ecological functions displayed by trees. Our survey was conducted in 6 public squares and 5 gardens in the Jardins neighborhood. We classified the trees according to their phytogeographic origins and seed dispersal habit. The Shannon-Weaver (H’) index, Simpson’s dominance (D’) and Pielou’s equability (J) were determined. A total of 507 individuals were sampled, located in 12 botanical families and 29 species, and 13 of them were classified as native and 16 as exotic. The family with higher species richness and number of species was Fabaceae (36%). Regarding the seed dispersal syndrome, the most representative was zoochory (52%). The ecological index showed medium species diversity (H’=2.2284), high dominance (D’=0.7899) and medium number of individuals (J) 0.6552. Although the Jardins neighborhood was planned, the urban forest in this area still needs improvement; such as incentive measures that can promote biodiversity and the application of ex-situ conservation.

The reduction or replacement of exotic ornamental plants by native species with ornamental potential is a current trend of landscaping. The insertion in the productive chain of flowers and ornamental plants and availability for commercialization represents a differential in a highly competitive market, attentive to novelties and tending to adopt products of reduced environmental impact besides promoting ex situ conservation. In this sense, the objective was to prospect species of the native flora of the Caatinga Biome that occur in the Valley of the Submédio São Francisco that present aesthetic elements appropriate for use in the landscaping. Incursions were made in the field to identify the species and were described the habit of growth, shape, symmetry, structure, texture and color of structures of higher ornamental value, fragrance, the presence of spines or not with indication of the possibilities of use. A total of 43 species were reported, distributed among herbaceous habit (21), bush habit (11), arboreal trees (9), both one climbing and hardy liana. Among the species indicated, 30.2% belong to the Fabaceae family. The flora of the Caatinga presents species with high ornamental potential for diverse uses and landscape effects. There is a need to stimulate the use of native species of the Caatinga Biome in landscaping projects, whose potential is still little valued.

AbstractUrochloa decumbens (Stapf) R. D. Webster (Poaceae) is an exotic species with has spread rapidly through the Cerrado area of Pantanal, Mato Grosso do Sul, Brazil. It has covered the soil aggressively turning it into cultivated pastures. Thus, it has become a challenge to protect native areas due its capacity of exclusion of native species. It has been observed that Microlobius foetidus (Jacq.) M.Sousa & G.Andrade species (Fabaceae) shows a dominant pattern over the development of U. decumbens. This work shows that M. foetidusinterfere on the natural growth of U. decumbens within 10 m ratio. Between 15 and 20 m, it was observed an increase of Importance Value index (IVI) and Relative cover (RC) values. It was also observed a variation on the antioxidant defense system of U. decumbens within 10m ratio from M. foetidus. The enzymes superoxide dismutase, catalase and peroxidase present higher levels of activity then those found for glutathione reductase. This data indicates that M. foetidus may have an effect on U. decumbens, increase the activity of antioxidant enzymes. This effect probably happens as means to neutralize the toxic effects of the oxygen generated due to the presence of allelochemicals, which increases oxidative stress.

Long drought and uncontrolled human activities resulted in R. Soerjo Prigen Pasuruan Grand Forest Park experiencing fire. Adverse impacts on vegetation can result in vegetation death. Damage caused by fire to vegetation can lead to succession which can be seen from the composition and structure of forest vegetation. The purpose of this study was to determine the effect of environmental parameters, structure and composition of plant vegetation in Tahura R. Soerjo, which were used as a learning resource for biology. This study used a purposive sampling technique. The method used is a combination of paths and checkered lines. The data analysis technique used is the Importance Value Index (INP), the dominance index, the diversity index, the wealth index, and the evenness index. The results showed that the identification of plant vegetation diversity was found as many as 33 species from 17 families that came from 3 divisions. The highest INP was found at the seedling level. The value of the dominance index is less than 1. The results show that the value of the density index is low, because it has a value of <3.5. The evenness value is at a high value, except at the tree level.
