Abstract

  The study on species and quantity of lichens in plant communities at Mae Wong National Park by laying out the survey and data collecting sampling in 4 forest types: lower montane rainforest, dry evergreen forest, mixed deciduous forest and dry deciduous dipterocarp forest. Five sample plots were allocated in each forest type, when field data collection was done during November 2012-February 2013. It revealed that 411 samples of lichen were found on bark and the forest floor. All specimens are identified in to 76 species 30 genera 16 families, which five most frequent  families are in colony of Physciaceae, Graphidaceae, Parmeliaceae, Trypetheliaceae and Usneaceae and were estimated at 27.63, 23.68, 14.47, 7.89 and 6.58 percent; respectively.


According to the plant communities analysis, it concluded that the highest Importance Value Index (IVI) in lower montane rainforest were Lithocarpus fenestratus, Quercus ramsbottomii, Castanopsis acuminatissima (33.08, 28.76 and 17.63 percent; respectively).The top most IVI in dry evergreen forest were Lagerstroemia floribunda, Grewia eriocarpa and Croton roxburghii (26.27, 23.29 and  21.42 percent respectively). Mixed deciduous forest contains the most IVI of Schleichera oleosa, Tectona grandis and  Xylia xylocarpa (51.10, 42.95 and 22.31 percent; respectively). The high range IVI in dry deciduous dipterocarp forest were Shorea obtuse and Shorea siamensis (98.99 and 60.01 percent; respectively)


It can be summarized that plant community in the lower montane rainforest composed of  37 species in 30 genera and 21 families and a variety of 35 Lichen species, in 18 genera and 9 families. The dry evergreen forest had 42 tree species in 40 genera and 26 families, and 29 lichen species in 15 genera and 12 families. The mixed deciduous forest had 40 tree species in 34 genera and 22 families, and 38 species of lichen in 13 genera and 6 families. The dry deciduous dipterocarp forest had 16 tree species in 18 genera and 11 families, and 34 species of lichen, 12 genera and 7 families. The dry evergreen forest had the most variety of tree species, where as the mixed deciduous forest had the most lichens species.
