Unusually harsh winter weather has affected the southern United States, with snowfall and freezing temperatures recorded in areas unaccustomed to such conditions. Lafayette, Louisiana, experienced approximately 8 inches (20 centimeters) of snow, a rare occurrence in the region. Meteorological reports indicated that temperatures could plummet to 12°F (-11°C) on the night of January 21, with sub-freezing conditions expected to persist until January 24. Experts highlighted that native flora and fauna, such as cypress trees, prairie plants, alligators, and snakes, possess evolutionary resilience to endure these environmental adversities. Specialists at the University of Louisiana at Lafayette emphasized that while individual plants might suffer damage, the genetic memory of native species ensures survival over centuries. Retired biology professor Phyllis Baudoin Griffard noted that native species have evolved mechanisms to withstand such extremes, although concerns were raised about Spanish moss, which lacks visible adaptations to heavy snowfall.

Efforts to mitigate the impact of freezing temperatures on wildlife and plants are ongoing. In Florida, horticultural experts affirmed that native plants could withstand the cold due to their long-term adaptations. The Houston Zoo implemented protective measures for animals by utilizing indoor facilities and backup generators. Wildlife conservation organizations collaborated to rescue sea turtles at risk of becoming cold-stunned from abrupt temperature drops. Reports also indicated that falling temperatures below 40°F (5°C) in Miami could immobilize iguanas temporarily, though healthy individuals were expected to recover. Experts concluded that these occurrences underscore the resilience of native species while highlighting the necessity of monitoring vulnerable populations during extreme weather events. The situation exemplifies how environmental extremes test the adaptability of ecosystems and species.
