Abstract

The aims of this study are to identify vegetation coverage and physical potential of land that can be developed as an ecotourism attraction, and plan for the management of ecotourism development space in the Field Laboratory of Forest Resources Conservation and Ecotourism, Unhas Educational Forest. Vegetation cover, was interpreted from satellite images by using remote sensing techniques, while the physical land potential data information was collected through direct measurements in the field by using GPS, compass and meter. Data analysis was done by using GIS with overlay method and Digital Elevation Model (DEM). The results showed that the Field Laboratory of Forest Resources Conservation and Ecotourism, Unhas Educational Forest, has natural forest vegetation and pine plantations forest covering 91.32% of the total land area of 311 ha, that potentially for the development of ecotourism. Some interesting physical potential to be developed as an ecotourism attraction, is a waterfall, mountain peaks, camping ground and a research station.

Abstract

This study aims to determine the potential of wildlife diversity that can be developed as an ecotourism attraction in the Field Laboratory of Forest Resources Conservation and Ecotourism, Unhas Educational Forest. The data was collected by survey method using the line transect method and concentration point count method. Data were analyzed to determine the ecological indices, ie; Richness Indices, Evenness Indices, and Diversity Indices. The results showed that Field Laboratory of Forest Resources Conservation and Ecotourism, have the wild life of mammals, birds, insects, reptiles and frogs that have the potential to be used in the development of ecotourism. The wildlife to be developed as an ecotourism attraction, are the Sulawesi Black Monkey, Tarsier, Couscous, Sulawesi Civets, Deer and Wild Boar, as well as a variety of birds, reptiles and frogs.

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

Pola penyebaran anakan jenis pohon emergent (Shorea sp.), kanopi (Maduca malaccensis) dan toleran naungan (Aglaia tomentosa) telah diamati pada hutan dataran rendah luapan banjir di Berau, Kalimantan Timur. Hasil penelitian menunjukkan bahwa, penyebaran anakan ketiga jenis pohon tersebut sangat dipengaruhi oleh agen dispersal buah. Anakan Shorea sp., yang mana memiliki buah tipe samara, sebagian besar tersebar pada bagian Utara-Barat pohon induknya, mengikuti arah angin yang menerbangkan buahnya. Anakan dua jenis lainnya, yang mana buahnya yang bertipe berry sangat disukai oleh binatang mamalia, menyebar secara lebih merata. Struktur populasi anakan ketiga jenis tersebut menunjukkan kecenderungan yang berbeda. Shorea sp. menunjukkan struktur populasi berbentuk huruf J terbalik yang sangat tajam, sedangkan struktur populasi anakan dua jenis lainnya cenderung berbentuk garis horizontal. Perbedaan struktur populasi tersebut terkait dengan toleransi jenis-jenis tersebut terhadap naungan. Buah Shorea sp. yang jumlahnya melimpah segera berkecambah setelah jatuh, namun pertumbuhan anakan selanjutnya tertahan oleh naungan kanopy hutan yang sangat rapat.
