Differences in forest structure and landscape patterns between ownership groups in Central Finland
The spatial distribution and connectivity of forest characteristics, such as soil productivity, stage of forest development, forest tree species composition and forest vertical structure, were studied according to forest ownership groups in Central Finland. The study was based on the data from the F...
