Proceedings of the 26th International Wood Machining Seminar, IWMS26, April 14th – 15th, Firenze, Italy, p 290-292 Abstract The in-situ wood evaluation aims to advance timber quality assessment by addressing it earlier in the supply chain, directly in the forest on standing trees and shortly after harvest on felled logs. This perspective provides forest owners with valuable insights into the quality of their properties, offering a clear understanding of the potential value of their trees. Unlike traditional methods, our approach is designed to provide quick and easy-to-use evaluations, saving time and effort while delivering enhanced value information. An inventory app is being trained to assess the stems of standing trees, generating a quality index that will be included in the inventory report for each forest parcel. Both forest owners and users will benefit from this enhanced understanding of forest compartment quality, enabling more efficient buying and selling decisions.
