Understanding and Mitigating Lightning-Related Animal Fatalities: Case Studies, Injury Pathways, and Protection Measures

This paper presents a comprehensive analysis of lightning-related animal deaths, drawing from documented case studies where large herds of livestock, rare wildlife species, and high-value animals have been killed or severely injured due to direct and indirect lightning strikes. The study investigates the underlying injury mechanisms of lightning on animals, focusing on the enhanced susceptibility of four-legged species due to their unique anatomical structure and electrical grounding pathways. In particular, the lethal current entry points are examined, demonstrating how step potential, side flashes, and contact potential contribute to fatal electrical currents passing through the animal body. To better understand these phenomena, various animal body models are explored to simulate the distribution of lightning currents and their physiological effects. These models aid in assessing the risk factors associated with different species based on size, posture, and environmental conditions. The paper also highlights critical environmental factors that exacerbate lightning-related injuries, including terrain conductivity, moisture levels, herd density, and sheltering behavior. Certain landscape features, such as open fields, water bodies, and metal fencing, are identified as contributing to increased lightning vulnerability. Finally, this study reviews effective mitigation strategies aimed at protecting animals from lightning hazards. Proposed solutions include structural shielding through properly designed shelters, strategic herd management to reduce clustering risks, predictive warning systems for early detection of thunderstorms, and the implementation of grounded protective measures in high-risk areas.
