“…Given that tree species studied were in the same edaphoclimatic conditions, the large differences observed between wood densities of the eighteen tree species could not be directly attributable to environmental conditions, but more to differences between species (Nogueira et al 2007;Gourlet-Fleury et al 2011). These differences could be explained by the intrinsic characteristics of species (Chave et al 2006;Zanne et al 2010;Zeidler, 2012). Guendehou et al (2012) already reported large differences in wood densities in the Lama forest.…”

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.

“…Several authors have shown that wood density varies significantly from pith to bark, with a difference that can reach 200 to 300 % in some species (De Castro et al 1993). This is particularly the case for temperate forests (Corylus colurna L. by Zeidler (2012)) and plantations (Eucalyptus grandis × urophylla by Baillères et al (2005)). Radial variation in wood density is associated with competition for light (Wiemann and Williamson 1989).…”

& Key message In a tropical rainforest of Madagascar, tree species differed in average wood density depending on their light requirements and on the soil type. Tree diameter had no effect. None of these factors influenced the variation of density related to the distance to the pith. & Context Wood density (WD) is an important wood property as it correlates with several functional tree traits and mechanical wood properties. Furthermore, wood density is often used in forest biomass and carbon stock estimates. The variation in wood density depends on a range of intrinsic or environmental factors. & Aims This study investigated the effect of species, tree diameter, soil types and the distance from the pith on wood density in native hardwood species from a natural, midelevation rainforest in Madagascar. & Methods We extracted pith-to-bark core samples from the trunk of 204 trees from 23 species. Each wood core was sectioned into 1 cm-long segments on which measures of volume and weight were performed. Within-tree and between-tree variations of wood density were analysed. & Results Average wood density was higher on shade-tolerant than on light-demanding species. It was higher on poor ferralitic than on fertile lowland soils. Tree diameter had no influence on average wood density. Regarding within-tree variation, wood density does not vary from pith to bark. & Conclusion These results help fill the gaps in wood properties database for tree forest species in Madagascar.

“…Different parts of the plant are valuable source of natural pharmacological compounds (Ceylan et al 2013;Riethmüller et al 2014). Its wood is decorative and has favorable mechanical properties (Korkut et al 2008;Zeidler 2012;2013). In addition, the nuts with high oil content (Erdogan and Aygun 2005) are not only a quality nutrition source for wildlife (Vander Wall 2001) but also used in confectionary industry (Miletić et al 2005).…”

Location and climate information of 18 natural Turkish hazel populations in Turkey is reported. Populations are small (mean area = 206 ha) and are found at 700 m to 1600 m above sea level. Mean annual temperature is 8.83 °C and (range: 6.9 − 11 °C) and mean annual precipitation is 654.28 mm (range: 477 − 952 mm) at population locations. The species is of interest in Turkey for plantation in arid and semi-arid regions but only three of the 18 population locations are classified as semi-arid. The rest of the populations are located in more humid environments. The genetic structure of these populations should be determined and a comprehensive gene conservation program should be put in place. A through genetic testing (provenance and/or progeny tests) should be conducted to determine suitable seed sources and families for plantation in semi-arid environments. ÖzetBu çalışmada Türkiye'deki 18 doğal Türk fındığı popülasyonunun konum ve iklim verileri irdelenmiştir. İncelenen popülasyonlar küçüktür (ortalama alan = 206 ha) ve deniz seviyesinden 700 ila 1600 m arasında bulunmaktadır. Popülasyon konumlarında yıllık ortalama sıcaklık 8.83°C (aralık: 6.9 − 11 °C) ve yıllık ortalama yağış 654.28 mm (aralık: 477 − 952 mm) olarak belirlenmiştir. Türün Türkiye'deki kurak ve yarı-kurak alanların ağaçlandırılmasında kullanılması yönünde bir ilgi vardır ancak incelenen popülasyonların sadece üçü yarı-kurak sahalarda bulunmaktadır. Diğer popülasyonlar daha nemli bölgelerde bulunmaktadır. Bu popülasyonların genetik yapısı belirlenmeli ve kapsamlı bir gen koruma programı gündeme alınmalıdır. Ayrıntılı köken (orijin) ve/veya döl denemeleri ile yarı-kurak sahaların ağaçlandırılmasında kullanılabilecek tohum kaynakları ve aileler belirlenmelidir.
