Severe winter weather has affected the southern United States, causing unusual snowfall and freezing temperatures in regions unaccustomed to such conditions. Lafayette, Louisiana, recorded about 8 inches (20 centimeters) of snow on January 21, an event described as rare by meteorologists. Temperatures were forecasted to fall to 12°F (-11°C) that night, with sub-freezing levels expected to last until January 24. Experts highlighted the resilience of native species like cypress trees and alligators, which possess natural adaptations to survive extreme conditions. However, species such as Spanish moss, lacking similar adaptations, were identified as being at risk.

Efforts to protect wildlife and ecosystems during these harsh conditions included various interventions. Zoos implemented indoor shelters and backup power systems to safeguard animals. Conservation groups worked to rescue cold-stunned sea turtles, ensuring their recovery. In Florida, horticulturists observed that many native plants showed robust resistance to the cold. Reports also indicated that temporarily immobilized iguanas in Miami were expected to recover as temperatures rose. These measures and observations highlight the importance of adaptability and strategic action in preserving biodiversity during extreme weather events.
