Fallen trees




A list of two data frames, where trees contains the locations (x and y coordinates) and heights (=marks) of 232 trees in a window with polygonal boundary, and window species the polygonal window (see examples).


The dataset comprised the locations and heights of 232 trees, which fell during two large wind gusts (1967 and 1990) in the west of France (Pontailler et al., 1997). The study area was a biological reserve, which had been preserved for at least four centuries, with little human influence for a long period (Guinier, 1950). Thus, the forest stand followed almost natural dynamics. It was an uneven-aged beech stand with a few old oaks.

The data was analysed in Myllymäki et al. (2017, Supplementary material).
