Abstract

The distribution pattern and population structure of Diospyros celebica under the conopy of their mother-tree stand were studied in the experimental forest of Hasanuddin University at Maros District. One hectar rectangular plot was established in the secondary natural forest dominated by D. celebica. All individuals of D. celebica found in the plot were recorded their diameter at hight 130 cm above ground level. Individual less than 130 cm in hight were categorized as seedling and measured their total hight from ground level. Analyzes using Morisita’s Distribution Index (Iδ) resulted in the distribution pattern of D. celebica was clumped for all life-stages (seedling, sapling, pole and tree). Distribution pattern of seedling was found to be not significanly correlated to the slope, but was positively and significantly correlated with the level of canopy cover of their mother-tree stand. Abundance of seedlings were found under the canopy of the mother trees. However, as the  individuals grow taller the correlation became weaker, until then the correlation became negative at the tree stage. This study also indicated that for all life-stages, more individual of D. celebica were found on the habitat with steeper slopes, but the correlation was not significant. The abundant number of seedling indicates that this species has a good ability in the natural regeneration process.

Abstract

Forest is a part of the ecosystem that provides environmental services. Deforestation may decrease forest function in an ecosystem. This study aims to build a spatial model of deforestation in a forest management unit (FMU) of Poigar. Deforestation analysis carried out by analyze the change of forest cover into non-forest cover with post classification comparison technique. Driving forces of deforestation carried out by spatial modeling using binary logistic regression models (LRM). Result of logistic regression model was used to predict the deforestation in 2013 and compare the prediction result with actual deforestation. The result showed that forest loss from the 2000 to 2013 period amounted 12,668.2 hectares. Deforestation in FMU of Poigar influenced by six factors there are distance from the road, distance from the settlement, distance from the river, population density, elevation and slope. Logistic regression model was built using five explanatory variables that are the distance from the road, distance from the river, population density, elevation and slope. Population density and accessibility is the most influented factor caused deforestation in FMU of Poigar. Prediction of deforestation could predict about 58 % of actual deforestation spatialy, so spatial models of deforestation could be an information to guidance on future management of FMU of Poigar.

Abstract

Natural regeneration of seedlings in mangrove forest is an important part of the secondary succession process. This research aimed to analyze the natural regeneration that occured in degraded areas of Kutai National Park, particularly in Bontang and Sangkima. Data collected was the presence of natural mangrove seedlings and measurement of environmental parameter i.e. soil and sea water. Vegetation inventory was conducted establishing plots placed intentionally (purposive sampling) at rehabilitation plot area of Bontang (0,98 ha) and Sangkima (1,04 ha). Composite soil samples were taken from five points in the plots at two different  soil depths: 0-30 cm and 31-61 cm. Water samples of 200 ml were collected from the plots. The results of this study showed that at both locations  six species of mangrove seedling were found. Bontang area consist of Acrostichum aureum,  Scyphiphora hydrophyllacea, Rhizophora apiculata and also Ceriops tagal species. Meanwhile, in Sangkima area species was identified as: Sonneratia alba, Rhizophora apiculata, and Rhizophora mucronata. Distribution of seedlings mangrove at Bontang area has strong positive correlation with environmental parameter of soil texture (silt and clay), soil chemical (CEC, N, C, Na, Ca), tides, and water chemical (salinity, NO3 and COD). In other hand, seedlings distribution in the Sangkima area have strong positive correlation with environmental parameters of soil texture (sand) and water chemicals (Mg, Al, pH, COD, BOD, DO, and TSS). In order to speed up of the restoration in degraded areas of Kutai National Park mangrove forest, it was need attention to suitability aspects of each species based on the environmental conditions of each site.

Abstract

This study aims to determine the level of farmers participation in the implementation of land rehabilitation and soil conservation (LRSC) techniques where appropriate to the micro watershed through PRA and PAR approaches. The techniques of LRSC both mechanical and vegetative methods have been built in a participatory manner in the demonstration plots of 2 ha in Datara micro watershed and of 2.5 ha in Mararin also micro watershed, South Sulawesi. Gully plug equipped with stick-scale and V-notch weir were constructed in Datara micro watershed and concrete tank of mud and runoff was built in Mararin micro watershed to monitor the impact of LRSC actvities to sedimentation and runoff level. The results showed the level of farmers participation at both locations fluctuated in the category of low (<50%), moderate (50-79%) and high (>80%) against targets LRSC activities that have been agreed at a meeting of the group. The level of participation is determined from the condition of the microhydro electric power who have built together. Participation of farmers on the application of LRSC on both plots are: willing to lend of their land for the location of demonstration plots, planting and maintaining trees for timber production, building and maintaining contour terraces and channel of water drainages, maintaining grass and gliricidia as reinforcement terraces for soil conservation techniques. Activities of LRSC impact plots show that layers of sedimentation and runoff volume decreased in the research sites. Demonstration plots in Datara, high sedimentation layer in the second year (2011) in gully plug average of 32.72 cm decline to 7.14 cm in the fourth year (2013), as well as runoff discharge 44.47 liter/sec in 2010  down to 22.8 liter/sec in November 2013. in Mararin plots the average height of a layer of mud in the tank in 2011 from  4.89 cm decline to 1.99 cm in November 2013 and the runoff volume 8.5 liter/sec down to 5.6 liter/sec at the same time.

Abstract

Global warming causes extreme weather and temperature leading to drought. Identification of drought adaptive species is essential. This research is aimed to examine growth, proline content and root anatomy of Acacia auriculifomis, Tectona grandis, Alstonia spectabilis, and Cedrela odorata and to compare the most adaptive species under drought condition. Controlled dry treatments applied were 10, 20, 30, and 40 days unwatered, and compared with control plants, each with 3 replications. Characteristics measured were height, diameter, leaf number and area, root proline content and root tracheal diameter. Data and samples were collected every 10 days. Growth and physiological data were analyzed by using T-Test, while anatomical data were analyzed by using ANOVA and DUNCAN test. Results showed that drought on A. auriculiformis, T. grandis, A. spectabilis, and C. odorata has decreased plant height, stem diameter and number of leaves but increasing proline content, and diameter of tracheas belonging to the roots. This study indicates that the most likely tolerant and adaptive species to drought are those that have the most variation of mechanisms to respond in which these characters would likely to appear at higher level of stress condition.

Abstract

Site quality is one of the main information needed in forest stand management. Site quality classes need to be evaluated every certain period because the quality of forest stands may change as a result of management applied. This study describes the use of very high-resolution imagery derived from unmanned aerial vehicle (UAV) for estimating the site quality of teak (Tectona grandis). The UAV imagery used was taken from 400 m above datum (the average land surface elevation) with ground spatial resolution of 15 cm. Site quality estimation models was built using discriminant analysis. The study found that the best accuracy from discriminant function using multiple variables canopy density (C) and average of crown diameter (D_c ̅) is 60.9%.

Abstract

The objective of the research is to identify the impact of Intensive Indonesian Selective Cutting and Replanting System (TPTII/SILIN) at dipterocarp production forest on understory birds community. Two forest blocks were compared, one with TPTII/SILIN and the other with Indonesian Selective Cutting and Replanting System (TPTI).  At each forest block, 10 of 4 x 10 m mist nets were installed for three days and then they were moved to other spot for other three days.  Mist nets were opened from 06:00 to 17:00 and monitored every 15 minutes.  The trapped bird was identified and body size measured, then subsequently released.  Data was analyzed by using Important Value Index, Shannon-Weinner Diversity Index, Margalef Species Richness Index, Simpson Dominance Index, and Sorensen Similarity Index.  Number of individu, number of species, Shanon-Wiener Diversity Index were compared statistically using student t-test.  The result showed that Ceyx erithacus and Arcahnotera longirostra hold the highest important value index in TPTI and TPTII/SILIN respectively.  Bird abundance, Shannon-Weinner Diversity Index and Margalef Species Richness Index were lower in TPTI than TPTII/SILIN.  Meanwhile Simpson Dominance Index was higher at TPTI than TPTII/SILIN.  Statistical analysis for the data of the two forest blocks showed significant differences on number of individual, number of species and Shannon-Weiner Diversity Index.  TPTII/SILIN was better in supporting understory birds community than those of TPTI.
