What's in a name?

Florida panther, cougar, mountain lion, screamer, catamount…all these names belong to one species, the Puma (Puma concolor). There are over 40 common names for these cats, and this is in part due to the sheer size of their range.

Puma are the most widely distributed mammal in the western hemisphere, and can be found from Canada to the southernmost tip of Argentina. These cats are highly adaptable and can be found in deserts, rainforests, and mountains.

Puma have 6 recognized sub species, only one of which is found east of the Mississippi River, the Florida panther (Puma concolor coryi). Florida panthers historically were found from parts of South Carolina across to Arkansas and from Tennessee to the tip of Florida.


Panthers Pushed to the Brink

Like many predators, panther numbers went down drastically due to persecution and loss of habitat. In the 1970s, the number of Florida panthers were unknown and they became the second animal put on the Endangered Species List in 1973 (Manatees were first). A survey conducted in the 1980s by Florida Fish and Wildlife revealed there was only around 20 cats left, and the numbers could have gotten down to 8 cats.

Due to their low numbers, isolation, and lack of genetic diversity, researchers were concerned that Florida panthers would become extinct in the near future. Florida Panthers started exhibiting signature traits such as a kinked tail and a cowlick on their back due to inbreeding.

In order to save the species, several government agencies collaborated to help the panthers by relocating 8 Texas cougar (Puma concolor stanleyana) females to south Florida. The Texas cougars were chosen because there had been genetic flow between these two populations of subspecies in their historic ranges. The addition of these females helped boost the population’s genetics, and the numbers of Florida panthers have slowly increased.

Bouncing Back

Today there are estimated to be around 120 to 230 panthers that are confined to 5% of their historic range. The Caloosahatchee River is the northern boundary of the breeding population of Florida panthers, with only males being found north of the river. In 2018, the first female panther with a kitten was seen just north of the river. This is wonderful news for the species, and since then another female with kittens has been spotted.

Threats to Panthers

As their numbers increase Florida panthers will have to push northward. With this good news comes challenges. With the numbers of cats increasing, there is also the higher chance of human/wildlife conflict, proper habitat, and vehicular strikes.

The number one reason for Florida panthers deaths is vehicular strikes (60%). It is important for researchers to understand the spatial needs of the Florida panthers and locate key corridors the cats use to help lower the number of these roadway deaths. Florida Fish and Wildlife, along with other agencies and conservation groups, have collared and tagged several cats, as well as using camera traps and aerial surveillance.


There have been over 230 Florida panthers killed by car strikes in the past 10 years, and with a population in the low 100s, each panther loss is tremendous blow.

Tracking Methods

There are various methods to tracking Florida panthers. The two more widely used by researchers are:

  • Collaring: Florida Fish and Wildlife needs to capture a representative sample of the population. To do this, they use dogs to track and tree a panther. When the panther is treed a biologist will dart the cat with a tranquilizer (don't worry they have a stretcher to catch it). When the cat is settled the biologists do a full physical on it, take samples, given vaccines, and finally they put identifiers on the panther (a radio collar, a microchip, and an inner ear tattoo).

  • Camera Traps: Camera traps are tools that allow us to capture images of panthers and other wildlife unbeknownst to the animals. These cameras allow researchers and enthusiasts to gain useful information about what areas panthers and their prey (White-tailed deer, Wild boar, etc.) are using. Thanks to their prevalence, anyone who has a camera trap and captures images of a Florida panther, they can send it to Florida Fish and Wildlife has a website and app that will confirm and map where the cat was spotted. Thanks to a camera trap in Babcock estates, researchers have the first photographic evidence of mating north of the Caloosahatchee.
