Habitat preferences of tigers Panthera tigris in the Sundarbans East Wildlife Sanctuary, Bangladesh, and management recommendations

Abstract

AbstractWe examined the habitat preferences of tigers Panthera tigris in four habitat types in the Sundarbans East Wildlife Sanctuary, Bangladesh. Transect sampling was used to count tiger signs. Mean densities of signs of feeding, resting, defaecation and interaction were significantly different between the four main habitat types (mangrove woodlands, grasslands, sea beaches and transitional areas), whereas movement, scratch-scent-urinal and other signs were not significantly different. This indicates that tigers have habitat preferences for at least some activities. Similar patterns were found in the densities of movement and feeding signs, as well as of resting and defaecation signs, across the four different habitat types. Tigers were found to use soft-barked trees for scratching more often than other types.
