The Dalweg Oak

Most oak stories are about longevity. This one is about plumbing. The Dalweg Oak has spent close to three centuries rooted on a slope where groundwater runs permanently just beneath the surface, so in the driest summer its roots still reach water, and in the wettest winter the slope drains before it can drown. That single accident of geology explains a tree with a 35 metre crown, wider than most Dutch houses are tall, and a trunk that measured roughly 6.2 metres around in 2015, thick enough to rank among the largest oaks in the country. It has not had an easy run at the top: a beech grew up beside it and a self seeded Douglas fir plantation crowded in later, both stealing light, and the oak has shed side branches in response for years. None of that has touched its vitality. Planted somewhere between 1700 and 1750, it stands above the walking path that climbs from Dalweg to Braamweg, one of the quieter corners of the Sonsbeek, Zypendaal and Gulden Bodem estate that the municipality bought whole in 1899 and never fenced off. No plaque marks it. You just have to look up while you are still catching your breath from the hill.
