An analysis on the impact of human over population in India on the environment using Induced Fuzzy Cognitive Map Model

Abstract :

Shorebirds are long-distance migratory species which are using many stop-over sites during their migration to fulfill their high energy requirements. The salt pans are the vital and significant habitats among the wetlands available in the costal ecosystem for the migratory shorebirds as alternate feeding grounds. The study was carried out from August 2012 to June 2015 in the five different salt pans of east coast of southern India. The shorebirds were counted by using total count method with the help of 7×50 binocular and 20x60 spotting scope from different vantage points. Totally 40 migratory and resident migratory bird species were recorded, in which 4 species viz., Red-necked Stint, Curlew Sandpiper, Eurasian Curlew and Painted Stork are categorized under ‘Near Threatened’ category as per IUCN 2016. The density of Little stint was highest than the other species recorded in the salt panss. The monsoon season supported highest density of shorebirds than the other seasons. The study concluded that the salt pans attract diverse array of shorebird species and they salt pans are act as an important feeding and roosting habitat for migratory and resident migratory shorebirds
