Dendrogeomorphology; Landslide; European larch; Norway spruce

We observed the same mean tree stem inclination for both tree species, whereas the inclination azimuths differed. L decidua generally showed a higher number of stem bends compared to P. abies. Similar proportions of subjectively identified GDs (compression wood, ON, and abrupt growth suppression, GS) and mathematically identified GDs (tree-ring eccentricities) were observed in both tree species. However, the total number of GD. tree(-1) was slightly higher in L decidua (4.1) than in P. abies (3.2). A higher abundance of GS was identified in L decidua at the expense of CW compared to P. abies. The event chronology based on the mathematical approach revealed slightly more landslide signals than for the subjective approach, mainly in L. decidua. However, the largest known landslide reactivation (in 1997) was recorded in all cases in both tree species.
