The severely threatened Chinese flora urgently needs a new, well adapted to China and properly formulated conservation strategy. The present review provides a detailed conservation methodology that complements previously described guidelines for preservation of plant species with extremely small populations(PSESP) in China. This review adds to the above concept in several aspects, making it relevant to all threatened Chinese plant species. The proposed integral conservation strategy has the following crucial components:-ecoregional basis for conservation planning and implementation;-a unified scoring system that is used in regional systematic planning for reserve design,monitoring and assessment of efficiency of a reserve network, and creation of seed banks and living collections;-a focus on population demography and the presence of naturally occurring regeneration as the key criteria for defining the conservation status of a species and the appropriate major focus of the species recovery plan;-creation of multi-species living collections that preserve species genetic variation and provide material for in situ actions;-experimental translocation of threatened species into multiple locations within and outside their known *** and implementing these strategies successfully and more fully in China requires that the country changes PA legislation and improves PA management, the National Science Foundation of China(NSFC) re-prioritizes the type of research that receives research funds, and local scientists improve their approach toward information sharing.

The need for integration of ex situ and in situ approaches in conservation of plants has long been recognized. However, ex situ collections have numerous limitations that reduce their utility for conservation, necessitating the introduction of new, more appropriate, flexible and less costly *** new approaches that can be called "intermediate" between in situ and ex situ, and bridging them in some way have been proposed over the last two decades. In these approaches material collected in natural populations is planted and maintained outside the original location, but with a different *** the purpose of the inter situs approach is reintroduction, the concern of the quasi in situ approach is long-term storage of species genetic diversity. I view these two approaches as complementary and necessary components of conservation-oriented restoration. In restoration of a degraded habitat using threatened species(i.e. inter situs), quasi in situ collections can serve an important role in providing longterm preservation of these species' genetic diversity and production of seeds needed for restoration.
