“…Similar results were found by MullerLandau (2004) and Yeboah et al (2014). In general, fast-growing trees are light demanding and produce low-density wood as found by Rueda and Williamson (1992), van Gelder et al (2006) and Henry et al (2010).…”

Highlights• Non-destructive sampling approach applied to derive ground truth observations and generate robust basic wood densities.• Species-specific and generic allometric equations.• Specific equations have better predictive capabilities than generic models. AbstractThe quantification of the contribution of tropical forests to global carbon stocks and climate change mitigation requires availability of data and tools such as allometric equations. This study made available volume and biomass models for eighteen tree species in a semi-deciduous tropical forest in West Africa. Generic models were also developed for the forest ecosystem, and basic wood density determined for the tree species. Non-destructive sampling approach was carried out on five hundred and one sample trees to analyse stem volume and biomass. From the modelling of volume and biomass as functions of diameter at breast height (Dbh) and stem height, logarithmic models had better predictive capabilities. The model validation showed that in absence of data on height, models using Dbh only as variable was an alternative. The comparison of basic wood densities to data published in literature enabled to conclude that the non-destructive sampling was a good approach to determining reliable basic wood density. The comparative analysis of species-specific models in this study with selected generic models for tropical forests indicated low probability to identify effective generic models with good predictive ability for biomass. Given tree species richness of tropical forests, the study demonstrated the hypothesis that species-specific models are preferred to generic models, and concluded that further research should be oriented towards development of specific models to cover the full range of dominant tree species of African forests.

“…The low CV might be due to small sample size and less variability within the selected individuals because, individuals with similar DBH were selected for sampling within each species. Similar variation within species was reported [12][13][14] . The WSG of stem was higher than both primary and secondary branch and this relationship was fairly consistent across species in this study (Figure 1).…”

“…Along the main stem of a tree, WSG varies from the base to the top of the stem 8 . Also stem WSG is generally higher than branch WSG 7,13,15 . However, WSG was also reported to decrease from the stump to half the total height of the tree, and later increase towards the top 16 .…”

Wood Specific Gravity of Trees in Hot Semi-Arid Zone of India:Diversity among Species and Relationship between Stem and Branches

Wood specific gravity (WSG) is an important parameter in allometric equations for accurate estimation of C-sequestration and other functional properties of a tree. However, WSG of many tree species especially of arid and semi-arid regions is poorly reported. Further, identifying indirect methods for determination of stem WSG from branches may be rapid and relatively easy. The present study determined WSG of stem and branches of 21 tree species in the hot semi-arid region of Western India. Three individual trees from each species were randomly selected and sampled for determination of WSG of stem, primary and secondary branch. WSG varied significantly among the species (F = 42.83, P < 0.001) and sampling locations (stem and branches) (F = 29.43, P < 0.001). In stem (at DBH), it ranged from 0.42  0.04 to 0.74  0.03 among the species while within an individual tree it varied in order of stem > primary branch > secondary branch in most species. WSG of stem and branches showed linear relationship and branches were found a good predictor of stem WSG (R 2 > 0.83).Keywords: Arid region, branch, tree biomass, wood specific gravity.INCREASING level of greenhouse gases (GHGs) especially CO 2 is a major cause of global warming and climate change 1 . Tree plantation provides a potential mitigation option for arresting climate change by absorbing and converting CO 2 into biomass through photosynthesis. However, direct method of estimating C-sequestration potential of a tree species is destructive, requiring harvesting of trees for determination of biomass and carbon. Cutting of trees in many countries is an environmental issue and legally not allowed especially in areas with scarce vegetation like semi-arid and arid zones. Allometric equations and models provide better option for nondestructive, indirect methods of tree biomass determination. These allometric equations have been reported to be more accurate when wood specific gravity (WSG) is included into the equation 2 . The wood carbon content is also highly correlated with WSG 3 . Thus, estimation of tree biomass and C-content depends critically on reliable information on WSG of trees. Research is being carried out to quantify potential of tree based C-sequestration in arid and semi-arid regions 4 . However, data on WSG of tree species found and grown in arid and semi-arid environment is scarce, leading to the choice of destructive methods of estimation. WSG of a tree varies with species and climatic condition 2,5,6 . The documentation of WSG of hot semi-arid zone of India is required for enhancing accuracy of allometric equation for better prediction of above ground biomass without harvesting of the tree. Further, variation in WSG has also been reported within the main stem and branches of a tree [7][8][9] . Determination of WSG of branches and developing relationship is useful and avoids the tedious process of wood core sampling and tree harvesting. With this background, the present study was undertaken to determine WSG of prominent tree species of hot semi-arid regio...

“…Different plant species may have a specific chemical composition and carbon compounds due to their metabolism, as physiology and morphology are linked to an optimal functioning under the ecological conditions where they have evolved (Sardans & Peñuelas 2014). Within a given individual, C concentration varies between tissues (Yeboah et al 2014), depending to a larger extent on the chemistry of such tissues (Savidge 2003) than on plant age or size (Bert & Danjon 2006). This study presents C concentration values for 175 plant species in 18 families from temperate, tropical, subtropical, arid and semiarid zones in Mexico to establish whether and how biomass C concentration differed across environments, taxa and plant tissues.…”

Reliable calculations of carbon stocks in forest ecosystems are crucial for proper implementation of global warming mitigation policies. Accurate estimations depend upon applying the correct factor of carbon (C) concentration for different forest species and tissues instead of the often assumed 50% carbon content. Despite the high forest species richness in Mexico and the increasing CO2 emissions, data on carbon concentrations in forest plant tissues are scarce. In this study, we determined variation in C concentration of different tissues for 175 plant species common in Mexican forests. C contents were estimated and contrasted for plant distribution, taxa, and plant structure (main stems, branches, twigs, bark, leaves, buds, fruits, roots and root cuticles). The mean C concentration across species was 44.7%. Species significantly differed in C concentration by tissue, environment and taxa. These multi-species data contribute to improve precision on estimates of C balance in terrestrial ecosystems, reducing the uncertainty in C inventories in Mexico and elsewhere.
