Compilation of an endangered plant species list for local Red Data Books based on an objective approach : a case study in Ushiku City, Ibaraki Prefecture(News)

Abstract

Recently, local governments in Japan have published Red Data Books as a baseline for regional biodiversity management. However, these books often lack explicit criteria for selecting endangered species and the detailed information required for implementation of effective conservation programs. Considering these problems, we compiled a Red Data Book of endangered vascular plant species for Ushiku City, Ibaraki Prefecture, based on an objective approach. We also tried to infer practical measures required for conservation of each species described in the new book.
