Douglas-fir Annual Rings

Caption

Douglas-fir typically has very well-defined annual rings, with a sharp definition between earlywood (light colored cells) and latewood (dark colored cells). For this reason, annual rings are very easy to count, making Douglas-fir a widely used species for dendrochronology and historical climate studies in western North America.
