AbstractTo preserve natural forests, forest plantations with fast-growing species are promoted. In the present work, the heartwood durabilities ofDyera costulata,Neolamarckia cadambaandKhaya ivorensis, from both plantations and natural forests, have been tested in comparison with rubberwood in laboratory and above-ground tests against the subterranean termiteCoptotermes curvignathus. Both young trees from forest thinning and mature trees were tested. The results show that there is no significant difference in weight loss between planted trees and trees from a natural forest. The results were also compared with those of rubberwood.

Sengon is a fast growing species that popular to be cultivated in Indonesia. It can be planted in agroforestry system with agricultural crop such as upland rice (padi gogo). Agroforestry system between sengon and upland rice is vulnerable to fungi attack. Micro fungi that may attack upland rice and young sengon is Rhizoctonia sp. This research aimed to analyze the interaction of plants in agroforestry between sengon and upland rice as well as Rhizoctonia sp. attack. The experiment was performed in community forest in Cikarawang village which dominated by 2 years old sengon. Agroforestry system in cikarawang village affected significantly to harvest productivity of upland rice but not affected to growth of sengon. Statistical test performed also showed that Rhizoctonia sp. attack to upland rice did not affect the harvesting result, but only affected to plant morphology.Keywords: dimension, fungi, rice, productivity

Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil.) is one of the fast growing species that became priority to be developed in South Halmahera Regency, North Maluku Province. Currently the red jabon has become “Local Superior Crops” in North Maluku. One of IUPHHK in South Halmahera which develops red jabon is PT. Telagabakti Persada. The purpose of this study was to determine the best growth of red jabon seedling on urea fertilizer application. The study was conducted at PT. Telagabakti Persada, South Halmahera. The treatments of urea fertilizer were 0 g,  0.25 g, 0.50 g, 0.75 g, and 1 g. The results showed that the urea 0.25 g  fertilizer treatment resulted in the best growth of red jabon seedlings.Key words: Red Jabon, Nursery, Growth of seedling, Urea

We present the study results of modern dendroflora of Donetsk (a large industrial city of the south steppe zone). We have determined the species composition, analyzed the age structure of plantations, estimated the life condition of trees and shrubs. Plantations compose 76 species and 32 forms, types, sorts of trees, including 11 species and 9 sorts of the coniferous, as well as 79 species and 35 forms, sorts of shrubs, including 7 species and 19 sorts of the coniferous. Trees and shrubs belong to 78 genera, which are included into 38 families. The most represented family among the deciduous is Rosaceae Juss. - 46 species and 13 sorts, among the coniferous - Pinaceae Lindl. (9 species and 6 sorts), Cupressaceae Rich. ex Bartl. (7 species and 22 sorts). Tree species dominating in plantations are Populus bolleana Lauche (14,6% of the total number of trees), dominating shrubs are the sorts of Rosa hybrida (44,0% of the total number of shrubs). In the plantations studied we have indicated 33 species of trees and shrubs of the aboriginal fraction of local flora. Analysis of the age structure of plantations revealed that the majority of trees compose the age group of 20-29 years, the majority of shrubs - up to 10 years. Fast-growing species prevail in plantations (73% of the total number). Viability of the most part of trees of fast-growing and slow-growing species is estimated by 4 points, viability of moderate-growing species - by 6 points. The number of trees being in unsatisfactory condition (0 or 1-3 points) prevails among fast-growing species.

Fast Growing Species

Deforestation of tropical dry forest reduces soil fertility, with negative effects on future restoration intervention. To evaluate the effect of initial soil properties on three-year performance of six tree species in restoration settings, we measured C, N, and P contents in topsoils of 48 plots under minimal (exclusions of livestock grazing) and maximal (plantings of six native species) restoration intervention during two years in tropical dry forest in central Mexico. Survival and height and diameter relative growth rates were evaluated by species and by growth rank (three fast- and three slow-growing species). After two years, organic C and the C:N ratio increased early during natural succession; these increases might be related to high density of N2-fixing recruits at both intervention levels. Changes in N availability for plants (i.e., NO3− and NH4+ contents) occurred after cattle exclusion. After 40 months, the fast-growing legume Leucaena esculenta (DC.) Benth. had the highest survival (65.55%) and relative growth rate in both height (3.16%) and diameter (5.67%). Fast-growing species had higher survival and diameter growth rates than slow-growing species. Higher diameter growth rates for fast-growing species may be associated with a higher ability to forage for soil resources, whereas similar height growth rates for slow and fast-growing species suggested low competition for light due to slow natural succession at the site. Planted seedlings had higher survival possibly due to initial high NO3− content in the soil. Also, fast-growing species seem to benefit from initially higher pH in the soil. Both soil properties (i.e., pH and NO3−) may be augmented to favor the performance of fast-growing species in restoration plantings and to further accelerate soil recovery in tropical dry forests.
