Wetlands of Ichhamati floodplains, India, are endowed repositories of native and migratory avifauna. However, unplanned utilization and unregulated resource extractions had led to the continual ecological deterioration of these wetland habitats. Considering avifauna habitability as an environmental manifestation of wetland health, the present study attempted to assess the habitability status of major 18 wetlands (> 10ha) of the floodplains under different livelihood dependency patterns. Accordingly, six widely used ecological indicators of avifauna distribution, species composition, and abundance had been applied to construct a composite index of avifauna habitability for two phases, viz. 2012-2013 and 2017-2018. Results indicated that wetlands with mixed livelihood practices (average habitability index score 2.471) were having statistically significant (p< 0.001) better habitability than those with agriculture and fishing dominated livelihood patterns (average index score 0.378 and - 2.746 respectively) in 2012-2013. The same scenario prevailed in 2017-2018 although overall wetland habitability was found to be declining throughout the floodplains during this period, especially in agriculture dominated wetlands (average index score 0.185). Faulty implementation of rural employment generation programs and distance cum lesser connectivity of wetlands with the perennial river channel had been identified as the prime detrimental factors of this degeneration and consequent loss of avifauna diversity.
