Flora list of wild vascular plants in Tohoku Research Center, Forestry and Forest Products Research Institute

Abstract

We surveyed the flora of wild vascular plants in Tohoku Research Center, Forestry and Forest Products Research Institute (Morioka, 39°46′04″N, 141°07′56″E, 191 m above sea level). As a result, 492 species of vascular plants in 320 genera, 112 families (29 of ferns, 10 of gymnosperms and 453 of angiosperms) are recorded. As compared with the previous flora list recorded approximate 40 years ago, 189 species are newly added while 91 species unfound. Newly added species are composed of many forest floor plants, while unfound species includes grassland plants. This reflects well the environmental changes over the past 40 years in Tohoku Research Center, where forestation is progressing.
