资源简介：
This dataset contains data from presence-absence registrations on the permanent plots of the Swedish National Forest Inventory. On each plot, registrations are made for two subplots. The data file is separated into three parts: the first contain information about the first subplot, the second about the second subplot, and the third about the union of the two subplots. Descriptions of the variables are given inside the data file.
