3. A Brief to the Reintroduction to Natural Habitat of Cycas debaoensis Project
Cycas debaoensis is an endangered cycad species distributed in western Guangxi and eastern Yunnan. With a unique, bamboo-like appearance, the species has suffered an abrupt damage after it was published. The total number of the wild 15 populations was less than 800 individuals. Supported by China State Forestry Administration, the center reintroduced 500 DNA-detected seedlings of C. ebaoensis which were propagated in the center to their hometown, Huanglian Mountain Nature Reserve, Guangxi in April, 2008. The follow-up surveys for three years indicated that the C. debaoensis seedlings grow very well, where is very near to the type location of the species. In 2011 the shooting rate of the fronds reached 97% and 8 individuals flowered. This achievement has been received extensive affirmation.
