Abstract

Maridi, Agustina P, Saputra A. 2014. Vegetation analysis of Samin watershed, Central Java as water and soil conservation efforts. Biodiversitas 15: 215-223. Samin watershed in Central Java is one of 282 Indonesian watersheds which are in critical condition.Nowadays, the sustainability of forest resources in the upstream of Samin watershed is threatened by exploitation of forest by people. Asa result, erosion and sedimentation are occurring in this area that may pose a threat of flooding and landslide. Therefore, we need seriousmeasures to maintain the function of Samin watershed, one of which is through the monitoring of vegetation in watershed. The purposeof this research was to analyze the structure and composition of vegetation in Samin watershed to support soil and water conservation.The survey of vegetation was conducted in 3 areas of Samin watershed based on geophysical conditions namely upstream, midstream,and downstream. At each sampling area, 37 sampling plots were randomly distributed in six observation stations. Vegetation analysiswas carried out in both the lower crop community (LCC) and the tree. Results showed that the number of LCC species found in theupstream, midstream, and downstream areas were 21, 34, and 28 respectively. The species diversity indexes of LCC vegetation in theupstream, midstream, and downstream areas were 1.04, 1.34, and 1.23 respectively. Based on this result, LCC vegetation in Saminwatershed was categorized in medium condition. The number of tree species found in the upstream, midstream, and downstream areaswere 27, 18, and 12 respectively. The species diversity indexes of tree vegetation in the upstream, midstream, and downstream areaswere 1.31, 1.15, and 0.97 respectively. Based on this result, the tree vegetation in Samin watershed was categorized in mediumcondition for the upstream and midstream areas, and low condition for the downstream area. Vegetation in Samin watershed must be preserved in order to maintain the sustainability of Samin watershed.

Abstract

Bhat S, Bhandary MJ, Rajanna L. 2014. Plant diversity in the homegardens of Karwar, Karnataka, India. Biodiversitas 15: 229-235. A study was conducted in 50 selected home gardens of Karwar, Karnataka, India to document their floristic diversity and composition withregard to life forms and uses. As many as 210 species of flowering plants belonging to 69 families were recorded. Euphorbiaceae(13species), Apocynaceae (11spp.), Cucurbitaceae (10 spp.) and Fabaceae (10 spp.) are the predominant families. Shrubs are thedominant life forms (73 spp.) followed by trees (61 spp.), herbs (42 spp.) and climbers (24 spp.). Areca palm (Areca catechu), coconutpalm (Cocos nucifera), mango tree (Mangifera indica), banana (Musa paradisiaca), shoe flower (Hibiscus rosa-sinensis) and holy basil(Ocimum tenuiflorum) are the most common plants occurring in all of the 50 studied gardens. 38% of the plant species are grown mainlyfor ornamental and aesthetic purposes while 33% of the species are used for obtaining food products like fruits and vegetables and 22%of the plants are mainly used for medicinal purposes. The predominance of ornamental species makes the home gardens of Karwardifferent from those occurring in other regions in which mostly food plants form the major component.

Abstract

Soejono. 2014. Rediscovery of a remnant habitat of the critically endangered species, Hopea sangal, in Pasuruan District, East Java, Indonesia. Biodiversitas 15: 236-239. During recent exploration for surviving indigenous flora carried out in Pasuruan District, EastJava, the endangered tree species, Hopea sangal Korth., has been rediscovered in a previously unknown location in East Java. TheIUCN Red List of Threatened Species, 2012, stated that H. sangal is critically endangered, A1cd, B1+2c, C1, D ver 2.3. This discoveryof H. sangal, and other supporting species that may still survive, can support the program of recovery of threatened plant species. At least for Pasuruan region, the remaining habitat, can be used as the core for H. sangal protection, thus H. sangal can breed naturally and sustainably. This information also can be used as one of the references or consideration tools for stakeholders to determine the priority of restoration policy.

Abstract

Setyawan AD. 2014. A new record of naturalized Selaginella uncinata (Desv.) Spring (Selaginellaceae) from Java, Indonesia. Biodiversitas 15: 261-268. During extensive field researches on the diversity and distribution of Selaginella in Java, between 2007 and2014, an alien species has been found in nature, i.e. Selaginella uncinata. This species is a trailing herb with small, wiry, creeping mainstem, fan-shaped branches, rooting at the nodes to c.a. 100 cm long or more; leaves are dimorphic, 4-ranked, and characterized byconspicuous blue iridescent; strobili are tetragonal, up to c.a. 2 cm long. S. uncinata was found growing wild in the highlands with highrainfall, namely: Cibodas Botanical Garden, Cianjur, West Java and Tawangsari, in the city district of Wonosobo, Central Java,Indonesia. Transplant experiments showed that this plant was able to grow and reproduce well in lowlands (Depok, 107 m asl.) andhighlands (Wonosobo, 768 m asl.). In the experimental garden, it could compete successfully with native species of Javan selaginellas, for space, sunlight and nutrients. Therefore, we must be concerned about the invasion ability of this species.

Abstract

Razali N, Ismail MH, Kamarudin N, Zaki PH. 2014. Effect of skid trails on the regeneration of commercial tree species at Balah Forest Reserve, Kelantan, Malaysia. Biodiversitas 15:240-244. Skidding operation has been reported as one of the factor to forest soildegradation and vegetation disturbance. Assessing tree regeneration by the effect of the skid trail from harvest operation is important todetermine the recovery rate of the forest stand. A study was conducted to accomplish the following objectives, (i) to measure the treeregeneration rates at different distance from skid trails, and (ii) to evaluate the dominance and species diversity of regenerated trees. Atotal of five plots with size of 50 m by 2 m were established in two skid trails of natural forest that has been logged in 2012. Each plotcontains five sub-plots of 2 m by 2 m in different locations namely skid track, edge and forest. The number of seedlings and saplings,species richness and diversity, and dominance regeneration were analyzed. Results showed that the number of species regeneration wasnot significantly different in both skid trails. For skid trail 1 the number of seedling and saplings was highest on skid trail tracks (meanspecies diversity = 0.45). Meanwhile skid trail 2 showed the greatest species regeneration at edges (mean species diversity =0.65).Frequency value for Elateriospermum tapos was high due to the existence of mother tree in the area that provides a great number ofseedlings. The dominance regeneration in both skid trails originated from non-dipterocarp families. There were 42 non-dipterocarp seedling and saplings in skid trail 1, and 182 in skid trail 2. While only 2 dipterocarp seedling and saplings in skid trail 1, and 8 in skid trail 2. Enrichment planting is suggested as dipterocarp species have low growth rate compared to the non dipterocarp species.

Abstract

Roslinda E. 2016. Dayak Desa forest land use system as social capital to acquire forest management rights in West Kalimantan, Indonesia. Biodiversitas 17: 177-184. People communities have an important role to play in biodiversity conservation. The ownership of land has often become a constraint on sustainable management of forest. The aim of this study was to explore the management system of forest land use in Dayak Desa in West Kalimantan, Indonesia. Data collection was undertaken through field observation, focus group discussion (FGD, and interviews with the community members. Dayak Desa has a several forest land use systems including tawang semilas, tawang sebesai, tawang mersibung, tawang sepayan, tawang serimbak and bukit rentap protection forest, which each system has its own function and utilization. Regardless of the system’s differences, the forest land use systems have been supporting species diversity such as flora, fauna, and environmental services in Dayak Desa. This species diversity can support Dayak Desa community daily needs, regarding food, clothing, housing and other secondary needs. Forest utilization by Dayak Desa community is suitably paired to what can be produced by the land, which is equipped with their own rules. The role and the rule in managing, utilizing and protecting forest land use are Dayak Desa social capital. These are capital to acquire their rights to manage the forest.

Abstract

Sudarmadji T, Hartati W. 2016. The process of rehabilitation of mined forest lands toward degraded forest ecosystem recovery in Kalimantan, Indonesia. Biodiversitas 17: 185-191. An overview of mined forest lands at East and Central Kalimantan Indonesia was conducted to determine most important influencing factors supporting degraded forest ecosystem recovery. Consecutivestages of rehabilitation processes consist of reclamation-backfilling, re-contouring, re-shaping, topsoils spreading, and revegetationland preparation, planting, maintenance covering minimum topsoils spreading, soil acidity, plant hole size, soil improvement application (dolomite, organic-inorganic fertilizers), vegetation planting vegetation planting (plant species selection-quality and site matching-verified plantmaterial sources, hardening-off, planting techniques), and land management implementation. The potential degraded forest ecosystem recovery was shown by cover crops and fast growing species plant and undergrowths, survive primary species, decreasing surface runoff/overland flows following increasing soil infiltration capacities, decreasing soil erosion rate and it’s erosion hazard, and an improved environments as habitat for invading wildlifes. The general characteristics of potential degraded forest ecosystem recovery after rehabilitation processes are: spread soil materials thickness > 70 cm, bulk density + 1,2 g.ml-1, soil acidity > 5,5, macro nutrients (N, P, K, Ca, Mg)-low to moderate, decreasing overland water flow following increasing soil infiltration capacity-moderate to high, decreasing soil erosion rate-very low to moderate, decreasing erosion hazard level-very slight to moderate, growing plants of fast growing species with significant layers and land cover, and growing interline planted primary species. Viewed from the ecological aspect, in the revegetated degraded forest lands wildlife such as insects, birds, reptiles, amphibians and small mammals were found feeding and alsopermanently living in ecosystem regeneration following gradual habitat improvement. The ecosystem status was identified as a progression towards degraded forest ecosystem recovery.

Abstract

Sugiarto, Boer C, Mardji D. 2016. Species diversity of cerambycid beetles at reclamation area of coal mining in Berau District, East Kalimantan, Indonesia. Biodiversitas 17: 200-207. Longhorn beetles (Cerambycidae) are amongst the most popular beetle families and hence lots of research has been carried out on the family. However, the presence of this beetle in the reclamation area of PT Berau Coal has not been investigated yet. PT Berau Coal is a coal company that has long been operated. In the former mining areas have been planted with reclamation plants. The study was carried out to determine the cerambycid beetle species diversity in three sites of the reclamation area, mainly Lati (L), Sambarata (S) and Binungan (B). This is the first report of cerambycid beetles diversity at areclamation area of PT Berau Coal. This study reveals a total of 16, 19 and 22 species with 100, 140 and 192 individuals respectively. Calculation with Simpson’s diversity index (1-D) resulted in highly index of biodiversity, namely 0.90, 0.89 and 0.89 respectively. These highly index of diversity is likely due to varied types of vegetation and distance from natural forest to study sites is relatively close. There were seven species respectively dominant at Lati and Sambarata reclamation areas, while at Binungan were six species.Simpson’s evenness index of Lati was the highest, followed by Sambarata and Binungan, that were 0.64, 0.53 and 0.41, respectively. This differences might be influenced by the ability of each beetle species to move to other habitats. Jaccard’s similarity indices at the three sites were relatively same; they were L with S = 0.45, L with B = 0.46 and S with B = 0.46. The similarity index reflects similar environmental conditions of the three study sites. From the viewpoint of nature conservation, it is concluded that post-mining areas canplay a key role in the conservation of beetle diversity since they are as new habitat for beetles species whose original habitats are now in critical condition due to human impact. An important task for future management of post-mining areas is to maintain successional processes and to prevent loss of habitat diversity through revegetation.
