What timber species are best for palisade construction?

The optimal species depends on the application and required service life. For ground-contact palisades (use class 4), European oak (durability class 2, 25–40 year service life), robinia/black locust (durability class 1–2, 30–50 years), and pressure-treated Scots pine (class 1 achieved, 15–25 years) are the primary options.

For above-ground landscape features (use class 3), European larch (durability class 3–4, 15–25 years) and Douglas fir (class 3, 15–20 years) offer good performance without treatment. Turned palisades in softwood are typically pressure-treated to UC4 standard for ground contact applications.
