This paper discusses the butterfly- flower interrelationships in a dry deciduous forest in Sathyamangalam Wildlife Sanctuary, Tamil Nadu, Eastern Ghats. A total of 86 species of butterflies belonging to five families were recorded in the study area. Butterfly foraging observations were recorded on 27 plant species belonging to 17 families. A total of 49 species of butterflies foraged on floral nectar of 21 plant species. Maximum number of flower-visiting butterfly species (n=17) belonged to Nymphalidae. Small-sized flowers (<1cm) attracted maximum number of butterfly species (n=48). Among the various flower colours, red were visited by maximum number of species (n=36). Mud-puddling behaviour of butterflies is also discussed.Keywords

The Attappady Hills Area Development Society (AHADS) as part of eco-restoration programmes in Attappady hills, Western Ghats, initiated tree planting programmes to identify the bird-attracting species. Study sites were chosen in the degraded dry deciduous forests of Attappady and the adjoining Anaikatty reserve forests representing the mixed dry deciduous forest. Frugivorous birds were ascertained by making extended feeding watches on fleshyfruited plant species and bird counts along transects. Twenty nine bird species were observed to eat fruits. Among the frugivore visitors, bulbuls (5 species) made highest number of feeding visits (45%), followed by mynas, 2 species (16%), babblers, 3 species (14.5%) and others. A total of 40 bird-attracting species were recorded in the study area. Moraceae represented by six species was found to be the most dominant bird-attracting family followed by Rutaceae and Euphorbiaceae. Among the 40 species, Ficus benghalensis attracted maximum number of avian frugivores followed by Ficus microcarpa, Benkara malabarica, Cassine glauca and Canthium dicoccum. A suggestion is made to plant the bird-attracting native species in the degraded sites of Attappady.Keywords

The present paper highlights the rediscovery of a less known endemic, critically endangered and IUCN red-listed species, Isonandra villosa Wight (SAPOTACEAE) from Dhimbam Ghats in Eastern Ghats/Tamil Nadu after a lapse of 85 years. The present collection forms the rediscovery and also shows extension of its known rangeof distribution.Keywords

This paper highlights the floristic richness and vegetation association in the Pathiramanal Island, an important mangrove location in Kerala, South-western coast. Ceriops tagal, Excoecaria agallocha and Cerbera odollam constituted the dominant mangroves in Pathiramanal Island. The need for conservation of this area is emphasized.Keywords

Tree diversity in tropical montane evergreen forest (shola) in the Nilgiri mountains, which is a unique ecosystem of the Western Ghats was enumerated. Two one hectare plots were established in the study sites of Longwood (LD) and Eppanadu (ED), in which all trees >20cm girth at breast height (GBH) were noted. Fifty five tree species belonging to 35 families were reported. Site ED harboured 7.3% greater species richness than LD. Species diversity did not vary much between the two sites. 874 individuals of 38 genera and 45 species of trees were encountered in site LD, whereas in ED 1013 individuals belonging to 39 genera and 46 species were recorded. Twenty two endemic tree species were encountered in the study sites. Lauraceae was highly dominant family.Keywords

A total of 158 species of birds belonging to 56 families was recorded in a lowland riparian forest in along Bhavani river in the Nilgiri Biosphere Reserve, India from August 2012 to July 2014. Of the 158 species of birds, 110 species were residents, 33 were winter migrants and 15 summer migrants. The order Passeriformes was highest in dominance followed by Piciformes and Falconiformes. Insectivores (47%) constituted the most predominant guild followed by frugivores (20%). Highest species richness (127) was observed in February and lowest (75) in July. Maximum diversity value (4.23) was recorded in December. Avifauna of the study area comprised one threatened species, Nilgiri Woodpigeon (Columba elphinstonii)- Vulnerable and five near-threatened species and four endemic species. This study illustrated useful information on bird diversity of a low-land riparian forest which serves as a baseline for future research and monitoring.Keywords
