Research Abstract	Young planted forests are expected to be suitable habitats for early-successional species. I attempted to examine 'per area' ecological values of young planted forests with varied area for early-successional species by field survey. I surveyed bees, birds, and plants in eastern Hokkaido, in which forestry is now being actively conducted. I developed statistical models considering imperfect detection and incomplete spatial coverage of survey, and applied models to the data. In the result, I did not found any species preferring large patches across the taxa. Given the certain area of young planted forests, single large patch and several small patches would have the same roles for early-successional species.
