Illegal logging is a major cause of worldwide deforestation, and demands for scientific methods to identify the geographic origin of timber are increasing. “Dendroprovenancing” is one such method, in which the origin of unknown wood is estimated by calculating correlations of the ring-width series of the unknown wood with reference trees of known geographic origins. We applied the dendroprovenancing method to carbon isotope network data of pinyon pines (Pinus edulis and Pinus monophylla) from…

Oxygen and Hydrogen Stable Isotope Ratios of Bulk Needles Reveal the Geographic Origin of Norway Spruce in the European Alps
The δ 18O, δ2H and δ15N values in P. abies bulk needles are a suitable proxy to identify geographic origin as they vary according to geographical position.
Stable Isotope Ratio Analysis for the Comparison of Timber From Two Forest Concessions in Gabon
Consumers are becoming increasingly aware of the environmental impacts caused by deforestation and illegal logging and there is an increasing demand for supply chain transparency and traceability of
DNA of centuries-old timber can reveal its origin
The results prove the strong potential of DNA analyses for identifying timber origin to the regional scale, but by combining these with the dendrochronological results, can control the exactitude of the aDNA approach and demonstrate a more nuanced examination of the timber sources for these historic structures.
Chemical Fingerprinting of Wood Sampled along a Pith-to-Bark Gradient for Individual Comparison and Provenance Identification
Background and Objectives: The origin of traded timber is one of the main questions in the enforcement of regulations to combat the illegal timber trade. Substantial efforts are still needed to
Multi‐variable approach pinpoints origin of oak wood with higher precision
Spatial variations of environmental conditions translate into biogeographical patterns of tree growth. This fact is used to identify the origin of timber by means of dendroprovenancing. Yet,
Genetic differences among Cedrela odorata sites in Bolivia provide limited potential for fine-scale timber tracing
The occurrence of multiple genetic clusters within sites suggests that Bolivian C. odorata populations contain several parental lines, resulting in limited potential for forensic tracing at a national level.
Chemical differentiation of Bolivian Cedrela species as a tool to trace illegal timber trade
The DART-TOFMS technique allows independent verification of claimed identity of certain Cedrela species in timber trade and suggests no potential to discriminate at the studied scale and for the studied species.


Checking the geographical origin of oak wood: molecular and statistical tools
The technique cannot permit the unambiguous identification of wood products of unknown origin but can be used to check the conformity of genetic composition of wood samples with the region of alleged origin, which could lead to major applications not only in the forest industry but also in archaeology or in palaeobotany.
Sampling strategy for stable carbon isotope analysis of tree rings in pine
Stable carbon isotope measurements in tree rings have been explored as potential indicators of past climate1,2, and as proxy data for reconstructions of the history of 13C/12C variations of
Strontium isotopes reveal distant sources of architectural timber in Chaco Canyon, New Mexico
The use of trees from both the Chuska and San Mateo mountains, but not from the San Pedro Mountains, as early as A.D. 974 suggests that selection of timber sources was driven more by regional socioeconomic ties than by a simple model of resource depletion with distance and time.
The climate-carbon isotope relationship in tree rings and the significance of site conditions
Considerable complexity exists regarding the relationship between tree ring δ 13 C and climate. We proceed from the theoretically derived and experimentally confirmed finding that the relative
Oxygen and carbon isotopic ratios of tree-ring cellulose in a conifer-hardwood mixed forest in northern Japan
Oxygen and carbon isotopic ratios (δ18O and δ13C) were analyzed for cellulose extracted from tree rings of 5 oak trees (Quercus crispula) and 4 fir trees (Abies sachalinensis) standing in a 1 ha plot

Tree-ring widths have long been a useful North American drought proxy [e.g., Cook et al., 1999, 2004]. A potentially rich, new tree-ring proxy associated with the tree's leaf-level moisture status is
