Conifers in Cupressaceae distribute in forests at above 1000 m in elevation and are threatened by fragmented habitats and over-exploitation. Our results indicate that conifer population sizes were small (ca. 100 individuals) with low propagules, especially C. lanceolata var. konishii. The ISSR data showed low genetic diversity at both population and species levels, an average of 0.1025 and 0.0701 for C. lanceolata var. konishii and F. hodginsii, respectively (at population level) and 0.1357 and 0.1145 for C. lanceolata var. konishii and F. hodginsii, respectively as well. Genetic differentiation among populations per each species was high (Gst = 0.2771 and 0.22554 for F. hodginsii and C. lanceolata var. konishii, respectively). Factors that contribute to a reduction of low genetic diversities and high genetic differentiation and the priorities for species in Cupressaceae are discussed as well.
Key words: Cunninghamia lanceolata var, konishii, Fokienia hodginsii, genetic diversity, ISSR markers, species conservation,
