Opis:
The focus of this review paper is to present the state of the art regarding RFID implementations in wood supply chains, covering the tree marking stage till the transportation to the final processor. The easier than ever collection of data using sensors and the emerging ability to exchange information in the context of the Internet of Things (IoT) form a very promising new environment for the optimization of wood supply chains. Driven by currently enhanced, ability to store different layers of information per merchantable unit (tree assortments at final or semi-final form or containers of woody biomass), RFID applications can provide valuable solutions and revolutionize wood supply chains by warranting traceability, combating illegal logging, minimizing waste and offering detailed information of the wood products properties, among other benefits that are presented in the text. The benefits can be identified at the ecological, social and economic levels, addressing the sustainability concerns of modern societies. To make use of this huge potential, a continuous flow and fusion of information at all supply chain stages must be taken for granted, as well as the close cooperation among stakeholders.

Opis:
The purpose of this study was to determine variation in the density of wood from different provenances, growing under the same soil and climate conditions. Samples were obtained from an experimental site located at the Siemianice Forest Experimental Station. We analyzed larch wood samples from trees aged 48 years, collected from six different provenances in Poland. Diameter at breast height (DBH) and tree height were used to calculate the parameters for sample trees, from which a 70 cm segment was cut, from breast height upwards (up to 2 m of tree height). Samples with dimensions 20 × 20 × 30 mm were obtained from the material. Sample volume was determined by stereometry. Relative density was determined for 890 samples. The highest wood density was found in trees from Czerniejewo, and the lowest in trees from Rawa Mazowiecka. Analysis of variance, including the mean wood density values of trees, did not demonstrate significant differences between provenances in terms of this characteristic. Mean relative density was higher in larch wood samples from the heartwood zone. The density of samples cut closer to the bark was lower, as the value was affected by the large content of sapwood. A relation was found between the provenances from which the study material was sourced and the relative density of wood.
