The little deer of the Florida Keys are found nowhere else in the world. Related to the white-tailed deer, the Key deer is not much larger than a big dog. Today, it is an endangered species. There are no more than a few hundred left. The little deer wander through backyards and front lawns. Reduced speed limits are posted, but many deer get killed by automobiles. It is against the law to feed them. That makes them lose their natural fear of people and cars, and more likely to get killed. The National Key Deer Refuge was established on Big Pine Key in 1957, but more land is needed. People who live on the Keys like the little animals, and efforts are being made to find room for building developments and also enough space for Key deer to thrive.
