The Key deer, the smallest subspecies of white-tailed deer, faces an ongoing battle for survival. Found exclusively in the Lower Florida Keys, with a population of roughly 600 animals, this unique creature is a symbol of the region's fragile ecosystem. Once on the brink of extinction, the Key deer's recovery story is a testament to conservation efforts, but numerous threats continue to challenge its future.

Why it matters

The Key deer is a symbol of the Florida Keys' delicate ecosystem, and its survival is crucial for maintaining the region's biodiversity. Despite past conservation successes, the deer remains vulnerable due to threats like vehicle collisions, disease, and environmental challenges posed by hurricanes and sea level rise.

The details

In the mid-20th century, the Key deer population plummeted to as few as 30 individuals due to unregulated hunting and habitat loss. The creation of the National Key Deer Refuge in 1957 and the passage of the Endangered Species Act in 1973 helped the population rebound to between 700 and 800 deer by the early 2000s. However, the current population is estimated at around 600, and the deer face ongoing threats such as vehicle collisions, disease and parasites, and the effects of hurricanes and sea level rise. Protecting the Key deer requires a multifaceted approach, including habitat acquisition, controlled burns, population monitoring, speed limit enforcement, and public education.
