Abstract:Studies on plant population viability analysis(PVA) since 1990s have been reviewed in this paper, which discusses: factors affecting plant population viability; methods and steps of plant PVA; plant PVA models; and challenges to plant PVAs. In addition, the accuracy and effectiveness of plant PVAs in management or conservation strategies, as well as their limitations and future development have been discussed. The factors affecting plant population viability can be divided into stochastic factors and de...
