Most of non timber forest product ( NTFP ) utilization taken from natural forests which decrease on productivity annually, including tengkawang producer species which taken from West Kalimantan natural forests. This condition needs an effort to preserve those species from natural population utilization through plantation forest development that require spesific strategy. This study was part of breeding strategy of s horea species producing tengkawang which aimed to species identify and seedling growth evaluation used genetic material from 2 (two) population from West Kalimantan. The research was arranged in 2 (two) steps, i.e.1) species identification used morphology characteristic difference, and 2) seedling growth evaluation (height,diameter,sturdiness). Seedling growth evaluation was arranged in RCBD, with 5 plot (combination of species and source population), contained 25 seedlings and 4 replications (blocks). The result showed that seedlings of s horea species producing tengkawang, i.e. S.stenoptera , S.macrophylla , and S.gysbertsiana can be different from its stipulae morphology characteristic. Growth of 10 months s horea species producing tengkawang seedlings were significantly different on height and sturdiness. Seedlings height were 67,19 – 88,79 cm, seedlings diameter 9,65 – 10,33 mm and sturdiness 7 – 9,21 in range. The best seedling growth was S.stenoptera and S.macrophylla from Gunung Bunga, West Kalimantan.

The development of remote sensing technology makes it possible to utilize its data in many sectors including forestry. Remote sensing image has been used to map land cover and monitor deforestation. This paper presents utilization of ALOS PALSAR image to estimate and map aboveground biomass at natural forest of Bogani Nani Wartabone National Park especially SPTN II Doloduo and SPTN III Maelang. We used modeling method between biomass value from direct measurement and digital number of satellite image. There are two maps which present the distribution of biomass and carbon from ALOS PALSAR image with 50 m spatial resolution. These maps were built based on backscatter polarization of HH and HV bands. The maps indicate most research area dominated with biomass stock 0-5.000 ton/ha.

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.

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.

This study aims to analyze and develop alternative forest and land rehabilitation based on land capability in catchment area Tondano lake. Inhibiting factors used in the analysis is the ability of land slope, drainage and infiltration rate. The results of the analysis obtained 42 units of land. Approximately 85 % belong to the class I - V and 15 % belong to the class VI-VIII. Furthermore, the proposed three models of forest and land rehabilitation as follows: (1) Sub East catchment area, proposed pattern-based agroforestry clove plants in cultivation area, (2) Sub South catchment area, proposed pattern of farm crops is designed in agroforestry systems so that the health of soil, especially soil organic matter content can be maintained to support sustainable agriculture, (3) Sub West catchment area, proposed pattern integrated farming cattle crops (maize + grass strip + terrace ridges). While in the forest area developed multi purposes forest on all catchment areas.

This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %, average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).

It was estimated that North Sulawesi needs 9,870,093.33 coastal vegetation seeds to rehabilitate the damage of coastal ecosystems which reach 14,805.14 ha, where the largest area 13.884 ha located in other land use. This study aims to provide information of seed germination techniques in Permanent Nursery Kima Atas, Manado. Research was arranged in complete randomized design as factorial with three replications. Ketapang (Terminalia cattapa) will obtain high viability in fluctuation of temperature and humidity, i.e used sand media, without wildlings and placed under 25% shade and rain. Keben ( Baringtonia asiatica ) through the incision and decay that placed in the open location will obtain viability until 90% within 2 months. Nyamplung (Calophyllum inophyllum) requires shell splitting in order to improve the viability and it can be done by cracking and stripping.
