Forest Rehabilitation

The success of forest plantation development can not be separated from the provision of good quality seed. Most of the work in the form of forest management activities of protection against pests. In supporting the successful planting of plant species dipterocarp seedlings need to do intensive maintenance at the time in the nursery. Because in the maintenance of seedlings in the nursery is always found pests which can cause harm. Meranti cultivation technique has been known among foresters in forest rehabilitation and plantation establishment. Shorea selanica included in the group of red meranti, has few pests that attack, economically destructive and detrimental. Eradication of pests is one that needs attention because without this effort can lead to failure on principle - the principle that the use of intensive silviculture techniques. Given the very low stands attacked by pests, the pest aspects should be considered because it can make the success of HTI problems if not addressed at an early stage. Maintenance seedling red meranti (Shorea selanica) in nursery plays an important role to support the success of planting in the field. However, in the maintenance of seedlings in the nursery is always found the existence of pests which can cause harm, cause the supply of saplings to be reduced. Symptoms of pest attack begin with perforated leaves wither and dry, then fallen leaves and dead plants.

The Impact

A study was conducted on the impact of forest clearance on discharge from newly established Hopea odorata plantations catchment (14.4 ha). The stands were two years old when this study commenced in year 2006 and the data collection was carried out for two years. The forested catchment (C3) was clear-cut during the preparation of the forest plantation and catchment C1 was left undisturbed. Discharge and rainfall were measured continuously for two years. The discharge measured from years 1997 to 2003 was used also to determine the water yield before and after forest clear-cut. This study showed that the plantation catchment is more responsive to storm with higher total water yield than in the forested catchment. The effect of forest clear cutting to discharge was clearly shown by the increment in the amount following the clear-cut activities and time taken for the recovery of the discharge back to its original state was almost three years. The peak discharge in C3 also was affected in which the biggest change was obtained during the forest clear-cutting period compared with during calibration and after clearing periods. This study is useful as basis for improving the existing guidelines on forest plantation establishment.

Dry And Rainy Seasons

The increasing of malaria cases in recent years at Kecamatan Kalibawang has been suspected correspond with the conversion of farming land-use which initiated in 1993. Four years after the natural vegetation in this area were changed become cocoa and coffee commercial farming estates, the number of malaria cases in 1997 rose more than six times, and in 2000 it reached 6085. This study were aimed to observe whether there were any differences in density and diversity of Anopheles as malaria vector between the cocoa and mix farming during dry and rainy seasons. The results of the study are useful for considering the appropriate methods, times and places for mosquito vector controlling. The study activities comprised of collecting Anopheles as well as identifying the species to determine the density and diversity of the malaria vector. Both activities were held four weeks in dry season and four weeks in rainy season. The mea-surement of physical factors such as temperature, humidity and rainfall were also conducted to support the study results. Four dusuns which meet the criteria and had the highest malaria cases were selected as study location. Descriptively, the results shows that the number of collected Anopheles in cocoa farming were higher compared with those in mix horticultural farming; and the number of Anopheles species identifi ed in cocoa farming were also more varied than those in the mix horticultural farming.Key words: bionomik vektor malaria, anopheles,
