Diversity and Distribution of Macrolichens in Shettihalli Wildlife Sanctuary, Westren Ghats, Southern India .

A total of 58 species of lichens were documented from the present study area, which is located between 14º 05' N to 75º 19' E longitude with wide range of ecosystem diversity at Shettihalli wildlife sanctuary, Shimoga district of Karnataka, India. We surveyed a total area of 396 sq km which yields 19 genera of lichens from 12 families. Some important Lichen species of the areas are Ramalina spp., Usnea spp., Heteroderma spp., Parmotrema spp. etc. Corticolous lichens were found to be dominated in abundance, represented by 86.2%. Foliose lichen forms were represented by 44 species and fruticose by 14 species. The present investigations showed that the deciduous forests support a good macrolichen communitys diversity then the semi-evergreen forests in nearby area. The study also highlights the record of two new species to Karnataka. They are Usnea picta (J.Steiner) Mot. Parmotrema praesorediosum (Nyl.) Hale. An interesting observation made in the area is that fruticose lichens were restricted to branches of the tree and main trunk was dominated by foliose lichens. Important host trees which support the growth and distribution of lichens in the area are Tectona grandis, Terminalia spp., Adina cordifolia, Hopea spp., and Xylia xylocarpa.
