PlantsGoals Main Goal: Re-enforcing its natural population. Goal 1: Assessment of conservation status of M. longipedunculata. Goal 2: Assessment of threats to M. longipedunculata. Goal 3: Experimental testing of artificial pollination for M. longipedunculata reintroduction. Goal 4: Enlarging population for M. longipedunculata.Success Indicators Indicator 1: Only one population with 11 individuals was found inapproximately 100 km 2 around the neighboring area. Indicator 2: The main threats to M. longipedunculata are established. Indicator 3: More than 2 kg of M. longipedunculata seeds were collectedthrough artificial cross-pollination. Indicator 4: A reinforcement population with 1,000 seedlings has beenestablished in the original habitat of M. longipedunculata. Indicator 5: An ex situ population with 200 seedlings has been established inSouth China Botanical Garden, Guangzhou, China.Project SummaryFeasibility: M.longipedunculata is only distributed in evergreen broad-leavedforests at 700 - 800 m on Mt. Nankunshan, Longmen County, GuangdongProvince, China. Only one sprouting tree was found when this new species waspublished in 2004. This species has high ornamental value because of itsbeautiful tree shape, large, elegant, fragrant and white flowers. It also has highvalue for good timber. Though the species diversity in Mt. Nankunshan isabundant, the vegetation is mainly secondary and artificial and had beendestroyed seriously before the establishment of Nankunshan Provincial NatureReserve. The over-exploitation, natural habitats degradation and naturalreproductive capability decline resulted in the threatening of this species in thewild and was listed in TheRed List of Magnoliaceaeas DD in 2007. Funded byBGCI since 2008, the fieldinvestigation andpollination biologicalexperiments of M.longipedunculata duringthe flowering and fruitingtime has been carried outby South China BotanicalGarden to evaluate itsconservation status andput forward efficientconservation strategies.M. longipedunculata fruits242
