KESESUAIAN LAHAN UNTUK HUTAN TANAMAN Climatic data such as elevation range, mean annual temperature, and mean annual rainfall were not considered because of the homogeneity of the study area from this point of view. Each class of every ecological parameter was classified with a determined value for each species. The value ranges from zero (worst conditions) to one (optimum conditions). This was done to show the behaviour of the species regarding the chosen parameters as shown in the Table 42 - Table 48.

HUTAN TANAMAN The Swieteniamacrophylla King, according to Lamb (1966) and Barros et al (1992), given the large area of occurrence of mahogany, and only in the Brazilian Amazon covers about 1.5 million km². It occurs in various soil conditions, from deep soil, poorly drained, acidic clay soils to well-drained alkaline soils that come from limestone plateau.

HUTAN TANAMAN Sombroek& Sampaio (1962): the predominant soil of occurrence of mahogany, is yellow podzolic soil with high base saturation and predominantly with imperfect drainage and rich in exchangeable bases. Similar to the soil, the climate in general terms given the extent of the species occurrence, some average data can be assumed: i) Average annual rainfall is approximately 2,000 mm; ii) average temperature varies from 23°C to 26°C, but depending on the region temperature may be lower, given the cold phenomenon, which occurs in the region between the states of Acre and Rondoniafor 3 to 80 days a year.

HUTAN TANAMAN Lamb (1966): Swieteniamacrophylla, King presents a high phenotypic plasticity, given its capacity to adapt to survive in different ecotypes, even under prolonged drought conditions, with less than 100 mm of rainfall per month in shallow, well-drained soils. Mahogany does not grow well in shaded forests and competition at the root system level. Thus, the species behaves as heliophile growing in an open forest. Since the early 1960s, Lamb (1966), noted that natural regeneration of Swieteniamacrophylla King takes place in places within the forest where sunlight reaches the ground, and where the litter layer is not thick, allowing the radicle to reach the mineral soil easily .

HUTAN TANAMAN MAHONI TOLERAN NAUNGAN Barros, et al (1992) and Lamb (1966) cited that the seedlings of Swieteniamacrophylla King in the shade presents low development, given the limited availability of energy for photosynthesis under conditions of understory of dense tropical forests. Mahogany seedlings need light to germinate and develop; therefore, they are classified as heliophila, so that when it occurs in forest openings have excellent growth.

SENGON : Paraserianthesfalcataria (L.) Nielsen Falcatariaoccurs naturally in Indonesia, Papua New Guinea, and the Solomon Islands from 10o S to 30o N. In its natural habitat it grows from sea level to 1200 m above sea level with an annual rainfall from 2000-4000 mm, a dry season of less than 2 months, and a temperature range of 22o to 34o C. Although it is likely to perform better on alkaline soils (NAS 1983), there are many examples of it growing well on acid soils. Correlation and multiple regression analysis show that topsoil depth is the most important indicator of site quality for falcataria (Dalmacio 1987). The most productive sites had at least 19-26 cm of well drained topsoil with at least 3-8% organic matter and an exchangeable potassium of 0.36 meq/100 g of soil.

JATI : Tectonagrandis Site effects - growth of plantations The main objective of teak plantation establishment is to produce high quality timber in trees with good or acceptable growth rates. Teak plantations have been established throughout the tropics, within and outside its natural distribution range. This covers a wide range of climatic conditions, i.e. from the equatorial type to the sub-tropical type with a range of rainfall and temperature of 500-3,500 mm and 2°-48°C (minimum and maximum range) respectively (Kaosa-ard, 1981). Soil conditions also vary from infertile acidic to fertile alluvial. A large variation in growth and other tree characters such as stem form, mode of branching, flowering habit and wood quality of the plantation commonly results. The mean annual volume increment (MAI) of teak plantations over a wide range of plantation conditions varies from 2 m3/ha/year to >15 m3/ha/year at the half rotation age of 30-40 years (FAO, 1956; White, 1991; Keogh, 1994). Keogh (1994) recommended that the MAI of teak plantation should be not less than 8m3/ha/year in commercial planting operations. . Sumber: http://www.fao.org/docrep/005/AC773E/ac773e08.htm …
JATI : Tectonagrandis Rainfall and moisture Teak grows naturally over a wide range of climatic condition, from the very dry (500 mm/year) to the very moist (up to 5,000 mm/year) (Seth and Khan, 1958; Kaosa-ard, 1981). Under very dry conditions, the tree is usually stunted and shrubby. Under very moist conditions, the tree is large and fluted and usually behaves like a semi-evergreen species; the wood quality is poor in terms of colour, texture and density. For the production of high quality wood with optimum growth, moisture conditions (as expressed by annual rainfall) should be between 1,200 and 2,500 mm with a marked dry season of 3-5 months (Kaosa-ard, 1981; Keogh, 1987). The dry season refers to a period in which the cumulative rainfall is less than 50 mm per month (Keogh, 1987). Keogh, R. M. 1980.

JATI : Tectonagrandis KUALITAS TANAH Teak grows best on deep, well-drained alluvial soils derived from limestone, schist, gneiss, shale (and some volcanic rocks, such as basalt. Conversely, the species performs very poorly, in terms of growth and stem form, on dry sandy soil, shallow soil (hard pan soil or lower water table soil), acidic soil (pH < 6.0) derived from laterite or peatbog, and on compacted or waterlogged soil (Kiatpraneet, 1974; Kaosa-ard, 1981; Bunyavejchewin, 1987; Srisuksai, 1991). Sumber: http://www.fao.org/docrep/005/AC773E/ac773e08.htm …
JATI : Tectonagrandis KUALITAS TANAH Teak soil is relatively fertile with high calcium (Ca), phosphorus (P), potassium (K), nitrogen (N) and organic matter (OM) contents (Bhatia, 1954; Seth and Yadav, 1958; Samapuddhi, 1963; Kiatpraneet, 1974; Sahunalu, 1970; Kaosa-ard, 1981; Bunyavejchewin, 1987; Srisuksai, 1991). Several studies indicate that teak requires relatively large amounts of calcium for its growth and development, and teak has been named as a calcareous species (Seth and Yadav, 1958; Kaosa-ard, 1981; Tewari, 1992). The amount of calcium content in the soil is also used as an indicator of teak site quality. That is, the greater the proportion of teak to other associate species, the higher the calcium content in the forest soil (Bunyavejchewin, 1983, 1987). Soil pH is another factor limiting the distribution and stand development of the species. Although the range of soil pH in teak forests is wide (5.0-8.0) (Kulkarni, 1951; Samapuddhi, 1963; Bunyavejchewin, 1983, 1987), the optimum pH range for better growth and quality is between 6.5-7.5 (Seth and Yadav, 1959; Kaosa-ard, 1981; Tewari 1992).

JATI : Tectonagrandis CAHAYA - Light Teak has been classified as a pioneer species. Hence, it requires a high light intensity for its growth and development (Kadambi, 1972; Kitinanda, 1969; Kwoboshi, 1974). A study conducted by Kwoboshi (1974) clearly demonstrated the effect of light intensity on the growth and development of teak seedlings; dry matter production of teak seedlings decreases sharply with a decrease in light intensity. In his study, the dry matter production of seedlings grown under low light intensity of 25% (for 8 months) was 0.6 gm as compared with 14.6 gm of seedlings grown under high light intensity of 75% of full daylight. The optimum light intensity for seedling growth and development is between 75-90% (Kwoboshi, 1974). Sumber: http://www.fao.org/docrep/005/AC773E/ac773e08.htm …
JATI : Tectonagrandis Temperature and elevation Temperature and elevation also play important roles in limiting the distribution and growth pattern of the species. It is known that teak grows well under warm and humid conditions. A series of studies in controlled environments indicated that the optimum temperature for growth and development of the species is 27-36°C (Gyi, 1972; Kanchanaburangura, 1976; Kaosa-ard, 1977). This range of temperature is quite normal within teak tropical range. Teak poorly tolerates cold and frost conditions during the winter period. Under frost conditions, seedlings and saplings are severely damaged and die (Kaosa-ard, 1981), one reason why the species cannot grow at elevations over 700 metres. Gyi, K. K. 1972.

JATI : Tectonagrandis Site quality has direct effect on the growth and development of the plantation. The rotation age can be greatly reduced through site selection. Teak grows well on moist sites. To produce high quality timber trees, the site should be subjected to a dry period of 3-5 months duration. Teak soil is deep, well- drained, and alluvial with high calcium, organic matter and other element content. The soil pH is 6.5-7.5. Teak is a light-demanding species. As a result, intensive weeding in 1-5 year-old plantations is very important. Sumber: http://www.fao.org/docrep/005/AC773E/ac773e08.htm …
