In situ and Ex situ Conservation of Commercial Tropical Trees - ITTO

254Nurprabowo. Results indicated that:1. The mean survival percentage at all sites is high,2. The heritability estimation value is relatively low for tree height and stemdiameter at all sites,3. Genetic correlation between tree height and stem diameter in Stagen,Mekarpura, Kepayang and all sites combined was 0.57; 0.79; 0.85 and0.76, respectively.Meranti Plantation Forest Establishment (PHTM)The Ministry of Forestry, in collaboration with the Faculty of Forestry, has aprogram to develop meranti plantation forests on a forest management unitscale.Each unit needs around 15, 000 ha of forest land of which 9,000 hashould be planted with meranti and the other 6,000 ha would be used for activitiessupporting the implementation of appropriate meranti plantations, such as:conservation, tree improvement, research related to intensive silviculture andbuffer zones for the local people. Each unit must be cultivated with 300 ha ofmeranti per year with 30 years rotation. This program, which was planned byProf. Soekotjo and approved by the Ministry of Forestry, has been socialized tosome Local Governments (Pemda). All State-owned Forest Companies(Perum Perhutani, Inhutani I–V) always participate in discussing the possibilitiesof meranti forest plantation establishment. Unfortunately, due to lack of fundingat the present time, they are still waiting for the opportunity to speed theprogram’s implementation. However, they are prepared to start working atany time.Seed Sources For Community ForestsAll the earliest tree improvement activities were conducted to meet the needsof the state forests. There was no any effort to meet the needs for goodquality seed on private lands or community forests until 1999. In that year, theDirectorate General of Forest Community and Land Rehabilitation, in cooperationwith the Faculty of Forestry, GMU established several seed stands/seed orchardsin Java, North Sulawesi, South Sulawesi, and South Kalimantan.Seed sources of Artocarpus heterophylla (nangka), Paraserianthesfalcataria (sengon), Armelaria campaca (cempaka), Aleuritas moluccana(kemiri), and some dipterocarp species have been established in Java, NorthSulawesi, South Sulawesi, and South Kalimantan, respectively. The maintenancelooks good and performance is generally promising.
