“…The fact that the highest proportion of the AGB is allocated in the stem has been widely documented, with the proportions ranging from 50 to 92% for different species [4,61,62]. Our results are within the same range, varying between 59.5% (Q. rugosa) and 80.9% (P. lumholtzii).…”

This paper presents new above-ground biomass (AGB) and biomass components equations for seventeen forest species in the temperate forests of northwestern Mexico. A data set corresponding to 1336 destructively sampled oak and pine trees was used to fit the models. Generalized method of moments was used to simultaneously fit systems of equations for biomass components and AGB, to ensure additivity. Additionally, the carbon content of each tree component was calculated by the dry combustion method, in a TOC analyser. The fitted equations accounted for on average 91, 83, 84 and 78% of the observed variance in stem wood and stem bark, branch and foliage biomass, respectively, whereas the total AGB equations explained on average 93% of the total observed variance in AGB. The inclusion of h or d 2 h as additional predictor in the d-only based equations systems slightly improved estimates of stem wood, stem bark and total above-ground biomass, and greatly improved the estimates produced by the branch and foliage biomass equations. The fitted equations were used to estimate AGB stocks at stand level from a database on growing stock from 429 permanent sampling plots. Three machine-learning techniques were used to model the estimated stand level AGB and carbon contents; the selected models were applied to map the AGB and carbon distributions in the study area, which yielded mean values of 129.84 Mg ha -1 and 63.80 Mg ha -1 , respectively.

“…Regression analysis show insignificant relationships between ages of stand and soil carbon (Table 2). These results are comparable to 8-year-old plantation in Vietnam and less than 7 year-old rehabilitated forest in Sarawak which ranged from 18.7-56.6 tC/ha (Ch'ng et al 2011 ;Sang et al 2013) but fall slightly lower that the value range (55.9-102.0 tC/ha) of the carbon stock as reported for secondary forest such as in young secondary forest in tropical regions (FAO 2010;Lu et al 2010;Fonseca et al 2011;Toriyama et al 2011;Ngo et al 2013).…”

The loss and degradation in tropical forest region are some of the current global concern. Hence, these issues elevated the role of rehabilitated forests in providing ecological products and services. The information on the carbon stock is important in relation to global carbon and biomass use, but lacking from the tropical region. This paper reports the assessment of tree and soil carbon stock in a chronosequence rehabilitated tropical forest stands in Malaysia. The study site was at the UPM-Mitsubishi Forest Rehabilitation Project, UPMKB. 20×20 m plot was established each and assessed in 2009 at 1-, 10-and 19-year-old sites while an adjacent ±23-year-old natural regenerating secondary forest plot was established for comparison. The overall total carbon stock was in the order of 19-year-old＞±23-year-old＞ 10-year-old＞1-year-old. When forest carbon stock is low, the soil component plays an important role in the carbon storage. The forest carbon recovery is crucial to increase soil carbon stock. The variations in the carbon stock showed the different stages of the forest recovery. Species survived after 19-years of planting are potential species for carbon sequestration activities in rehabilitated forest. Human intervention in rehabilitating degraded forest areas through tree planting initiatives is crucial towards recovering the forest ecological role especially in forest carbon stock capacity.

“…The forests and pasture land accumulate more organic matter than the CU soils. Fonseca et al (2011) found that, in Costa Rican tropical soils under secondary young forests (YF), the soil had an annual growth rate in carbon content of 1.09 Mg ha −1 and that in all of the variants of different forest age, the amount of carbon accumulated in the soil was higher than in the biomass.…”

The transformation of primary forestlands into lands under cultivation exerts an impact on the physical and chemical properties of the soils, leading to loss of carbon from the soil. The aims of this study were (1) to estimate the impact of different land use on organic carbon stock (OC-stock) and (2) to determine the clay percentage, the dispersion factor, and bulk density with regard to soil management. Thirty soil profiles were sampled as follows: four under primary forests with 80-100 years (old growth); two under secondary wood forests with 45-50 years; eight under secondary young forests with 15-25 years; four under pasture land with 15-20 years; and 12 under continuous cultivation for > 50 years. We determined the changes in OC-stock in the soils under different land-use conditions in relation to the primary forest variant.There was a difference in the OC-stock of the continuous cultivation variant compared to the remaining land-use variants for all soil-thickness layers. The greatest loss of cultivated soil was in the 0-20 cm layer of the primary forest OC-stock. In the 50-100 cm layer, the OC-stock of the cultivated soils diminished significantly. As regards physical properties, such as clay percentage,, dispersion factor, and bulk density, we observed significant differences between the cultivated soils compared to the remaining land-use variants.
