Douglas fir (Pseudotsuga menziesii) is found from central California, up through the Pacific Northwest, throughout the Rockies (variety glauca) and southward down into our sky islands. We are so lucky to have it as a part of the mixed coniferous forests in the mountains of the borderlands. What a magnificent tree! I highly recommend reading about its ecology and history..a small assignment. The photos are mine and taken the day of our tree hunt. That’s Marian…Ms. Mesquitey… looking over the other side of that deadfall and finding a Douglas fir.
