Population Characteristics and Conservation of Cycas fairylakea

  • Received Date: 2012-12-10
  • To study the population characteristics of Cycas fairylakea D. Y. Wang, a comprehensive field investigation was conducted with the help of GPS system. In this study, the quantitative characteristics and age structure of the genet were analyzed, and their distribution pattern and grow conditions were evaluated. In investigation, 1 013 C. fairylakea trees were found,which distributed in patch. Although the population scale and structure get better recovery,being limited by the topography and microclimate conditions, the growth conditions and natural proliferation ability of the population is still very fragile. To make C. fairylakea get rid of endangered status, it is proposed to establish a protection area for it and adopt necessary measures to promote the regeneration and development of the population.
