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 Philippine forest plantation lease is modelled as an option whose value arises from market uncertainty and the irreversibility inherent in sunk costs required to establish plantations. The value of this option could be a significant factor in the planting decisions of leaseholders. Real options theory could help explain why in spite of the prospects of adequate financial returns, Filipino leaseholders are slow to establish plantations. The opportunity cost of investing is demonstrated to be highly sensitive to uncertainty of the future value of the plantation. Real options analysis is also utilized to evaluate policies intended by the Philippine government to promote plantation development.

Pengelolaan hutan mangrove merupakan hal yang penting dalam mengupayakan pelestarian lingkungan di kawasan pesisir. Tujuan penelitian adalah untuk mengetahui dampak kegiatan rehabilitasi hutan mangrove dan strategi pengelolaan hutan mangrove di Desa Tanggul Tlare, Kecamatan Kedung, Kabupaten Jepara.Penelitian ini menggunakan pendekatan survei dengan wawancara langsung dan pengamatan lapangan. Populasi adalah seluruh penduduk pesisir di daerah penelitian, teknik pengampilan sampel menggunakan “cluster random sampling”. Dampak yang ditimbulkan dengan adanya rehabilitasi hutan mangrove di daerah penelitian adalah meningkatnya hasil tangkapanikan, mengurangi abrasi pantai, menahantiupan angin laut, semakin banyak tangkapan biota (udang, kepiting, kerang) di pesisir, danmenjadikan kawasan tersebut menjadidaerah objek wisata. Strategi yang perlu dilakukan dalam pengelolaan hutan mangrove diantaranya yaitu memanfaatkan potensi yang ada dengan dengan melakukan penanaman pohon mangrove, membentuk kawasan hutan lindung konservasi hutan mangrove agar kawasan hutan mangrove tetap terjaga baik dan lestari, memberikan sosialisasi atau pemahaman kepada masyarakat akan pentingnya menjaga hutan mangrove dan manfaat yang didapat oleh masyarakat, pentingnya kemajuan teknologi dan memberikan beasiswa kepada masyarakat yang dikira berkompeten dan aktif dalam rehabilitasi mangrove untuk melanjutkan sekolah yang lebih tinggi agar ilmu pengetahuan yang didapat bisa memberikan kontribusi yang positif untuk pengelolaan hutan mangrove yang ideal..Kata kunci: hutan mangrove, masyarakat, pengelolaanEnglish Title: Mangrove Forest Management Strategy In The Village Of Environmental Tlare District Kedung District JeparaABSTRACTManagement of mangrove forests is an important aspect in the effort to conserve the environment in coastal areas. The purpose of this research is to know the impact of mangrove forest rehabilitation and mangrove forest management strategy in Tanggul Tlare Village, Kedung Sub-district, Jepara Regency. This research uses survey approach with direct interview and field observation. Population is the entire coastal population in the study area, sample technique using cluster random sampling. The impacts of mangrove forest rehabilitation in the study area were increased fish catch, reduced coastal abrasion, retained wind breeze, more biota catches (shrimp, crabs, shells) on the coast, and made the area a tourist destination. Strategies that need to be done in the management of mangrove forests include the utilization of existing potentials by planting mangrove trees, establishing protected forest areas of mangrove forest conservation so that the mangrove forest area is maintained well and sustainably, providing socialization or understanding to the community about the importance of maintaining mangrove forests and Benefits gained by the community, the importance of technological advancement and providing scholarships to people who are thought to be competent and active in mangrove rehabilitation to continue their higher education so that the knowledge gained can contribute positively to the management of the ideal mangrove forests.Keywords: mangrove forest, community, managementCitation: Utomo, B., Budiastuti, S dan Muryani, C.

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.
