  • Title
    A preliminary survey on the avian community of Dalma Wildlife Sanctuary, Jharkhand, India
    Type
    Journal Article
    Description
    Dalma Wildlife sanctuary is a high altitude protected area and 3000 ft) in the state of Jharkhand (India) where surveys have been conducted from 2006 to 2008 for monitoring avifauna. Four permanent transects of 2km length and 100m width were used at four different sites within the sanctuary to determine species richness. Five permanent sampling points were established in each transect and a distance of 100m was maintained between them. The Shannon-Wiener diversity index was calculated for each site. Similarity between sites was determined by Sorensen’s index while differences between them in terms of species richness and diversity value were determined with the help of one-way analysis of variance. A total of 71 species belonging to 57 genera and 36 families were identified. Species richness and diversity were similar among sites in a particular season (ANOVA p and 0.05), however, bird species richness and abundance showed significant variation among seasons with a peak during the monsoons. Due to the presence of nearby tourist spots, the sanctuary is now facing various threats in terms of conservation issues. The conservation values of the Dalma Wildlife sanctuary in protecting endemic and threatened avifauna are briefly discussed and certain suggestions have been made on the basis of the present investigation for habitat improvement and eco-tourism.

  • Title
    Species composition and seasonal variation of butterflies in Dalma Wildlife Sanctuary, Jharkhand, India
    Type
    Journal Article
    Description
    Dalma Wildlife Sanctuary is located 10km from Jamshedpur in Jharkhand, India. The species composition and seasonal variation of butterflies was analyzed in this sanctuary over the course of 2 years. A total of 39 species belonging to 31 genera and 4 families were identified. Of these, Nymphalidae and Pieridae were found to be the dominant families, in comparison to Lycaenidae and Papilionidae. The monthly diversity was calculated by using the Shannon-Weiner diversity index. The highest diversity was found during late winter and spring while a comparatively low diversity was observed during the rainy season and summer. Nymphalidae showed the greatest variation with respect to distribution of species richness throughout the year. Nymphalidae and Lycaenidae showed greatest species richness and relative abundance during the rainy season. Little seasonal variation in species richness was observed in case of families Pieridae and Papilionidae
