Abstract:Davidia involucrata Baill., the only species in Family Davidiaceae, is a rare and endangered plant endemic to China surviving from the Tertiary. It is listed in the China Plant Red Data Book under first-grade state protection, and is irreplaceable for global biodiversity protection due to its special species status. We summarized the research progress on its population protection, concentrating on three questions: its endangered situations and the potential mechanisms, nursing techniques and protection strategies. Then we gave our suggestions for future research.
Keywords:Davidia involucrata  endangered mechanism  population protection  review
