Four major habitats of the Nanjenshan Preserve, based on
climatic and topographic interactions, include the following:
windward I, windward II, leeward, and creek type. Differences
in survivorship and growth rate of the seedlings between these
habitats were tested by growing about 2 month seedlings of four
representative species within each habitat. Both Illicium
arborescens and Rhaphiolepis indica var. hi- iranensis showed a
high survival rate (over 80 %, except in wi- ndward), and
Mallotus paniculatus represents the lowest (under 40 %, except
in gap); The survival rate of Schefflera octophy- lla was found
to be variable, although all measurements were higher than 50%.
Only Mallotus paniculatus revealed significant differences
between habitats in survival analyse. The results of ANOVA
indicated that growth rate was hightest for all speci- es
within the gap area than those of the other habitats.
Differences in the growth of the seedlings was also obser- ved
in strong response to seasonal changes. Beside gap site, there
was no singnificant difference in survival rate and growth
between habitats under the forest. This was probablily due to a
short period of experiment. A longer period observa- tion of
study and more information about seed production and seed
dispersal were needed to explain the segregation patterns of
the vegetation.
