The devastation caused by two back-to-back hurricanes in the Caribbean and southeastern U.S. has been tragic for the people that live(d) in these areas, but we haven’t really heard much about the impact of Harvey and Irma on the wildlife there. The massive deforestation caused by record high winds and extensive flooding in low-lying areas leaves little habitat and forage for resident wildlife, and will certainly prove challenging for the migratory birds that make their way south through these areas this fall.
High winds and storm surge swamped the Florida Keys as well, where the diminutive Key Deer live. These pint-sized relatives of the very common White-tailed Deer are endemic to the island chain, but exist there in relatively low numbers (700-1000 animals) on the Key Deer reserves on Big Pine and Little Torch Keys.
You would think their small size might make them vulnerable to being swept away in hurricane winds and/or floods, but the Key Deer have inhabited these islands for the past 13,000 years and have somehow survived the worst of inclement weather there. A story today in the Washington Post reports a sighting of 4 Key Deer crossing a local road, so at least some of the population has survived. Low population numbers is a long-term concern, however, since increased inbreeding can lead to an accumulation of detrimental recessive genes, and result in reduced fitness and resilience to cope with weather disasters like the recent hurricanes there.
