Tree ring data for analysis of RW and GS

The dataset contains tree-ring measurements and growth-disturbance records collected from 200 Norway spruce (Picea abies) individuals sampled across three mechanically distinct zones of a large complex landslide. For each tree, the dataset includes stem inclination, age, visually quantified reaction wood (RW) intensity for every affected ring, and classifications of abrupt growth suppression (GS) based on relative ring width reduction. Each disturbance entry is assigned to its corresponding landslide zone (S, G, or B), enabling spatially analysis.The data forms the basis for the article: Schlesinger, F., Šilhán, K., 2026. Geophysics-based landslide zonation explains spatial variability in tree-ring growth disturbances.
