Abstract

The aim of this study was to investigate the diversity of lichens in Rongko Conserved Forest, Ubon Ratchathani University. Quadrat random sampling method with 10x 10 m2 was used in dry deciduous dipterocarp forest, dry evergreen forest, secondary forest and rubber forest. Each quadrat sampling, 10 x 10 cm2 was laid on east side of trees that have bole diameter more than 4.5 cm at 130 cm above the ground, making up a total of 40 trees in 4 quadrats. Species of lichens and number of thalli in all quadrats were recorded. External structure; type of thallus, color, reproductive structure, internal structure; spore and spot tests with 10% Potassium Hydroxide ( KOH) Sodium Hypochlorite ( C) and Iodine ( I) for color changes were used for lichen identification. The result showed that 74species 38 genera 19 family were identified. The highest Shannon – Wiener's Index was found in the dry evergreen forest followed by dry deciduous dipterocarp forest, secondary forest and rubber forest at 3.33, 3.26, 2.68 and 2.23, respectively. The five highest importance value index (IVI) were Chrysothrix xanthina followed by Buellia curatellae, Glyphis scyphulifera, Dirinaria picta and Lecanora helva at 27.35, 16.93, 14.77, 14.71 and 13.60, respectively.Keywords : lichens ; species diversity ; Rongko Conserved Forest
