Carbon sequestration and growth of Anthocephalus cadamba plantation in North Kalimantan, Indonesia

Sarjono A, Lahjie AM, Simarangkir BDAS, Kristiningrum R, Ruslim Y. 2017. Carbon sequestration and growth of Anthocephalus cadamba plantation in North Kalimantan, Indonesia. Biodiversitas 18: 1385-1393. Forest plantation of Jabon (Anthocephalus cadamba) plays many important roles for the primary source of timber production and also the carbon absorption for environmental amelioration. The growth of A. cadamba trees was measured using the formulas of MAI (Mean Annual Increment) and PAI (Periodic Annual Increment) as the basis of the increment measurement, while the analysis of biomass and carbon with simple linear regression (y = a + bx) was used, with the coefficient of R2 = 0.90. The annual increment of A. cadamba trees reached its maximum point or the intersection between MAI and PAI at the age of 8 years, showing the maximum production of A. cadamba trees. Forest plantation of A. cadamba produced biomass and carbon sequestration of 81.90 ton ha-1 and 39.31 ton ha-1, respectively at the age of 8 years. However, the amount of biomass and carbon in another plot of A. cadamba trees was 96.85 ton ha-1 and 46.49 ton ha-1, respectively. While the values of the third plot were 116.84 ton ha-1 and 56.08 ton ha-1, respectively. The correlation between the diameter and biomass production and the correlation between the age of stands and carbon production were very strong with R2 value was higher than 0.90. This indicated that Jabon (Anthocephalus cadamba) plantation had important roles in carbon sequestration and biomass production.

In Quercus serrata, radial variations of wood fibre length, earlywood vessel element length, and earlywood vessel lumen diameter were investigated and maturation ages of them were estimated using nonlinear segmented regression analysis as proposed by Peszlen (1994). In addition, the age at the maximum point of current annual increment and mean annual increment were estimated by using the Gompertz growth function fitted to the variation of cumulative ring width with ring number from the pith. In the same radial strip, the maturation ages both of wood fibre length and the earlywood vessel element length were similar, and those were close to the ages at the maximum point of current annual increment, whereas the maturation age of earlywood vessel lumen diameter was generally greater, close to the age at the maximum point of mean annual increment. These results indicate that earlywood vessel lumen diameter is the best indicator of the three anatomical properties tested and that a relationship exists between the maturation ages of the size of axial elements and radial stem increment.

The objective of this work was to determine biomass production and nutritional efficiency in three eucalyptus genotypes in the Pampa Biome. For determination of biomass and nutritional characterization, nine medium trees per genotype were sampled, separated in the components leaf, branch, bark, wood and root. The nutritional efficiency of the biomass components was determined using the biological utilization coefficient (BUC). The highest biomass production and mean annual increment were observed in the Eucalyptus urograndis hybrid with 158 Mg ha-1 and 47.2 m³ ha-1, followed by Eucalyptus grandis with 137 Mg ha-1 and 39.7 m³ ha-1 and Eucalyptus dunnii with 122 Mg ha-1 and 23.2 m³ ha-1. For wood, the best nutritional efficiency was provided by Eucalytpus urograndis for P, Ca, and Mn, followed by Eucalytpus grandis for N and Mg, and Eucalytpus dunnii for K.

This study examined the effects of planting spacing on growth, yield, and wood properties of teak planted at square spacing regimes of 2 m, 3 m, and 4 m at Longuza Forest Plantation, Tanzania. To achieve this, tree, stand, and wood properties were studied at age of 14 years. Results showed that diameter at breast height and total height increased with increasing spacing. Mean annual increment increased significantly with increasing spacing while spacing did not have significant effect on total volume production and basal area. Basic density is also not affected by spacing while heartwood proportion increases as planting spacing increases. All studied wood properties (modulus of rupture, modulus of elasticity, compression strength tangential to grain, and shear tangential to the grain) except cleavage tangential to grain were not significantly affected by increasing spacing. It is recommended to use the spacing of 3 × 3 m, but if thinning can be done before onset of competition at 5 years, the currently used spacing of 2.5 × 2.5 m can still be used. However, the use of a spacing of 4 × 4 m can give at least 50% heartwood at shorter rotation age of 30 years.

A study of aspen sucker stands subjected to repeated harvesting at the Petawawa National Forestry Institute compared biomass production at rotations of 1, 2, 3, 5, 8,13, and 20 years. The shortest rotation at which sucker production can be physiologically sustained is unlikely to be less than 10 years. Biomass mean annual increment appeared to culminate at about 15 years. Declining yields at the shorter rotations were thought due mainly to starvation of rootstocks by the frequent removal of the photosynthesizing tops on which they depend for nourishment. High incidence of Armillaria infection in stump roots probably contributed to the diminished quantity and size of suckers, and may prove to be a serious factor in short-rotation systems for aspen. On the basis of foliar analysis there was no evidence of nutrient deficiency at any rotation.

The objectives of economic assessment of forests, growing on rich soil and environmental conditions, are especially important for the Republic of Tatarstan, as forest site conditions are presented, mostly, fresh suramens and sudubravas. The aim is to develop an algorithm and a mathematical model of the tax and market value dynamics of stands, needed to justify the choice of target tree species. The object of the study is served as detached electronic database of forestry and forest taxation indices of Kama region, general commodity tables and rate per unit volume of standing wood. The methodology of the study was consistent sort and organize raw data on the studied parameters, as well as the drawing up of mathematical models of the dynamics of the studied parameters. According to the research rezults the algorithm of selecting the target tree species was developed, providing the highest economic benefit in cultivation. The pine stands are most profitable to grow at fresh suramens and oak forests at fresh sudubravas. Age of stand’s economic maturity, which occurs at the climax moment of values of mean annual increment of its tax value, is much lower for most tree species, than the established standard terms of logging.
