Abstract

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.

Abstract

The present study aims to determine the type of fodder available and the level of scarcity of Anoa’s fodder at the condition prior to captivity at the Forestry Research Institute of Manado. The method employed was a trial of 12 (twelve) types of fodder available around the captivity site given to 2 (two) female anoas. The data were analyzed and displayed in tables and graphs while the data of preferred fodder were analyzed using Neu’s index equation. The findings suggest that anoa put in captivity at the Forestry Research Institute of Manado did not encounter problems during the process of feeding adaptation. The average fodder needs required anoa at the captivity site of  the Forestry Research Institute of Manado range from 10.2 to 11.7 kg/ day in which the fodder was given twice a day. Meanwhile, based on the availability and ease of supplying the fodder from around the captivity site, the following are the types of fodder from higher to lower preferences, namely: field grass, kangkung, shoes banana, string beans, beans and cucumbers, respectively. While fodder with the lowest level of scarcity is the type of fodder with a hard texture such as sweet potatoes, carrots or potatoes. Based on the results of a number of studies, it is recommended that variations in anoa’s fodder can be done every 4-5 times a day.

Abstract

The objective of this research is to evaluate the ecosystem functions through vegetation and wildlife indicators.  Methods used are vegetation analysis and direct indirect method to count wildlife .  Results show that the dominant type of land coverage in Gunung Ambang Nature Reserve is open secondary forest, where shrubs, rattan, and epiphytes dominated.  This might lead to vulnerability of the site toward disturbance.  Furthermore, it was indicated that this area still contains local wildlife species such as Babyrousa babyrussa celebensis.  Eventhough land degradation has become a significant issue, the status of Gunung Ambang as nature reserve has limited restoration attempts both vegetatively and mechanically.

Abstract

Most of primary forest after exploitation era in Indonesia was converted into secondary forest including Forest Management Unit of Poigar. On the other hand the understanding of forest vegetation will help ecology restoration efforts. This study aims to analyze the structure, composition and tree species diversity of Inobonto Poigar I. In order to accomplish the proposed objectives, 31 plots of 20 m x 20 m were randomly established in the forest area where number and name of tree species in each plot was identified and counted. The research was conducted on September 2014 and recorded a total of 78 species within measured plot. The average basal area of the forest was 16,77 m2/ha and the size class distribution was different from primary forest which is resembled a reserved J-shaped pattern. Trema orientalis was found as the dominant species among tree and pole levels, whereas Piper sp. dominated sapling level respectively. The Shannon-Wiener index showed that sapling has the higher diversity than tree and poles. The result of structure and composition analysis of vegetation has indicated that Inobonto I forest is secondary forest.

Abstract

Secondary forest of Indonesia covered about 24.2 % of total land area and dominated by post logging forest. The discourse to manage all forest area into Forest Management Unit (FMU) as the smallest management unit has been established, including post logging secondary forest. Therefore, understanding the diversity of secondary forest vegetation will help to decide its future management. This research aims to analyze composition, diversity and structure of post logging secondary forest at Nunuka, North Bolaang Mongondow of North Sulawesi. In order to accomplish the proposed objectives 30 plots of 20 m x 20 m were established in research area where number and name of tree species were identified and counted. The research was conducted on November 2014. The result recorded 84 tree species in research area. Anthocephalus macrophyllus dominated tree phase, whereas Eugenia sp. dominated both of poles and sapling. Shannon-Wiener index indicated low and medium diversity, whereas species abundance of tree, ploes and sapling were almost spread evenly. Vegetation density over all vegetation phases was 485.83 tree/ha, the average basal area of the forest was 35.15 m2/ha and the size class distribution did not resembled a reserved J-shaped pattern as found in primary forest. However J-shaped pattern showed in graphs of ten dominant species in both of tree and sapling level. Keywords: species composition, structure, secondary forest, North Bolaang Mongondow
