Abstract

Sambhar Lake, India’s largest inland saline wetland and a Ramsar site, supports diverse migratory bird populations. In recent years, the lake has experienced significant environmental changes due to industrial activity, unregulated salt extraction, agricultural runoff, and wastewater inflow, altering key ecological parameters. These changes have led to recurrent outbreaks of avian botulism caused by Clostridium botulinum, resulting in large-scale bird mortality since 2019. Despite repeated incidents, there is a lack of predictive tools for outbreak assessment. This study based on data from Nawa region of Sambhar Lake develops a logistic regression-based correlation model to estimate outbreak probability and provide an early warning framework for effective management.
