DendroScan is a system developed for measuring tree-ring width and density. Tree rings contain a record of diameter growth and carbon storage in the tree trunk. The width of the rings can be measured using a variety of systems, but the density (carbon storage) is most easily measured by X-ray densitometry. The DendroScan system eables the user to meaure both tree ring width and density, or just ring widths. The system can use prepared wood samples (for ring widths only) or X-ray images. DendroScan is fully described, with discussion of sample preparation, calibration procedures, and data analysis. Information and instructions for the user are included. The DendroScan program is enclosed on a DOS-formatted disk, along with a precalibrated precision wedge for converting X-ray images to density.
