This study was carried out at Mae Klong Watershed Research Station, Amphoe Thong Pha Phum, Changwat Kanchanaburi, during October 2005 to September 2006, which aimed to assess on figs diversity and applied the geographic information system (GIS) to search for the figs suitable habitats. Five road lines were set up for data collecting with the total distance about 25 kilometers. Those lines were designed to cover all the main habitat types including Mixed Deciduous Forest (MDF), Dry Evergreen Forest (DEF), Deciduous Dipterocarp Forest (DDF), and old Shifting farm land. All figs which located along the line, 10 meter in width, were identified and the recorded location by GPS. Diversity analyzed by Shanon and Weiner Index. Finally, GIS application by overlay technique was used to detect the suitable site of figs. The results showed that 22 Ficus species were accumulated. GIS result indicated that the fig suitable habitats depended on moisture factor and those species could be classified into two groups, 1) moisture-specific group, such as Ficus ischnopoda Miq., F. squamosa Roxb., F. auriculata Lour., F. montana Burm.f., F. callosaWilld., F. fistulosa Reinw. ex Blume and F. racemosa L. and 2) non moisture-specific group, such as Ficus annulata Blume, F. callophylla Blume, F. drupacea Thunb., F. geniculata Kurz, F. globosa Blume, F. hederacea Roxb., F. hispida L.f., F. microcarpa L.f., F. rumphii Blume, F. semicordata Buch. ñHam. ex Sm., F. sundaica Blume, F. variegata Blume and F. virens Aiton. The latter group had developed the stomata to protect against water loss.References
