This white pine is the largest and possibly the oldest tree on my property. It has a DBH (diameter at breast height or 1.3 meters) of 92 cm, and I estimate its age at about 180 years old.

The white pine probably began growing sometime around 1845. This was at the beginning of the white pine logging era in Minnesota. By 1900, it would have been large enough to cut for timber, but it was missed. The 1918 fires that swept through the area also missed it by just two short miles.

All through the 20th century, it continued to grow undisturbed. Over time, a forest of paper birch, aspen, balsam fir, and spruce grew under the pine. Beneath the trees, clubmosses, poverty oats, rough rice grass, purple melic grass, twinflower, and hairy goldenrod covered the ground. The forest had come back.

When other white pines on this 40-acre section were cut down for lumber in 1960, this huge white pine was not cut down. So were four other large white pines and five large red pines. I don’t know how or why this happened, but I am glad they were overlooked. What would this forest be without them?

Logging of Minnesota’s white pine forests began in the 1830s, but it wasn’t until the 1870s, with the advent of railroads and new settlements, that it really took off. By 1900, Minnesota had produced almost 1.2 billion board feet of white pine timber. This was not to last, and by 1929, nearly all of Minnesota’s white pine forests were depleted, bringing white pine logging to an end. While not remnant trees from old-growth forests, these white and red pine trees are survivors from that time.
