État de la populationTexte officiel évaluation IUCNExpert

This species is represented by a single mature individual, preserved on the top of Foding Mountain, due to destruction of the vegetation and the habitat. This tree was discovered in the early 1930s. Since then no more wild individuals have been found. This species is monoecious so could still reproduce in the wild but it has a very low rate of seed production due to strong winds during flowering and seed-setting stages and repeated destruction caused by typhoons at the seed-ripening stage. Natural regeneration therefore is extremely poor and almost no seedlings are found under the tree. Studies of genetic diversity of different progenies from C. putoensis revealed that there was a very low level of genetic diversity in C. putoensis.

Description complète des menacesTexte détaillé évaluation IUCNExpert

This species is threatened by habitat loss, a lack of regeneration and storms or typhoons. As only a single mature individual remains, genetic diversity will always be low, making it susceptible to pests and/or disease.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Putuo Island has been proclaimed a nation's key nature reserve and a special management bureau has been formed accordingly. This species is under first-grade state protection. Carpinus putoensis has been given full attention by the organization. Recently a fence has been erected around the tree to keep tourists away. The tree is cultivated in the Hangzhou Botanical Garden where various propagation experiments are being conducted. This species is also part of a conservation programme led by the Zhoushan Institute of Forestry. This has involved cultivation and planting of approximately 79 individuals in a one hectare near in situ reintroduction site, close to the remaining single mature individual. These 79 individuals were planted 30 years ago, but have not yet reached maturity.

Zhoushan Institute of Forestry is also propagating a supply of plants to be planted on Huaniao Island, next to Putuo Island, establishing an additional near in situ reintroduction site providing further protection for the species, and enabling reintroduction to Putuo Island in future. Full floristic survey of Huaniao Island is also under way. If C. putoensis is found on Huaniao Island in situ conservation measures will be put in place.
