Distribution and Conservation Strategy of Endangered Parakmeria Iotungensis
濒危植物乐东拟单性木兰的分布现状与保护策略

Distribution,resource,population structure and community character of rare and endangered species Parakmeria lotungensis were investigated.The results showed that P.lotungensis had a sporadic distribution among tropical and subtropical forests between 18°44′-29°24′N,107°50′-119°09′E,with a total population of less than 15000 individuals among which less than 2500 were mature individuals.Habitat fragmentation and biological and ecologi-cal characteristics of P.lotungensis were important factors for population regeneration.Human destruction was most direct factor contributing to the rapid reduction of the population.Protection strategies of P.lotungensis are discussed.
