What is the Species?
Puma concolor coryi. The Florida Panther is a subspecies of cougar that has adapted to the subtropical environment of Florida.
How Many Panthers Are Left?
Only 80 to 100 panthers still remain in Florida, making this one of the most rare and endangered mammals in the world.
Where is their Habitat?
Florida Panthers are usually found in pinelands, hardwood hammocks, and mixed swamp forests. Adult males may range over an area of 200 square miles, while females range over a 70 to 80 square mile area. Florida panthers are very solitary animals. An adult maintains a home range to live, hunt and, if female, raise its young alone. A male panther’s home range is very large and averages 275 square miles and overlaps with the smaller home ranges of females. Panthers maintain boundaries by marking with scents. They rarely fight over territory.
Panthers are most active at dusk and dawn, they can travel 15-20 miles a day, often moving in a zig-zag pattern, though they tend to rest during the daytime, travel & hunt during the cooler hours of the night. Panthers can swim and will cross wide bodies of water. They have a keen sense of smell and a field of vision of 130 degrees, they have excellent depth perception but lack the panoramic view that deer have.
They can run up to 35 mph but only for a few hundred yards, their preferred method of hunting is to creep up as close to their prey as possible and launch a short spring attack. Panthers do become used to man-made noises and frequently cross roads. They are attracted to woodland fires, and may stay near burned sites for days as deer and other prey are drawn to new vegetation. When humans approach an area they will either be still, disappear, or attempt to circle behind. Panthers can live up to between 12-15 years in the wild. A male can measure 7-8 feet from the nose to tail tip and weight 100-160 lbs. Females are about 6 feet in length and weight between 60-100 lbs.
What About Their Breeding Habits?
The Life Cycle
What Kind of Hunter is the Panther?
Efficient is the word. Adult male panthers weigh up to 150 pounds and can measure almost 7 feet long from the nose to the tip of the tail. Females are smaller, rarely weighing more than 100 pounds. Panthers are built to hunt live prey. Deer and wild hogs are their preferred food, but, when these are not available, panthers will eat raccoons, armadillos and even alligators. Interestingly, panthers eating a diet of small animals are not as healthy as those with plenty of deer to hunt. While they are good sprinters, panthers rarely chase prey for long distances. Instead, prey is singled out, stalked and ambushed.
What are the Threats?
We are. This also means that we can directly affect the panther’s future. It’s sad to say that Florida panthers are killed by cars and trucks, particularly on State Road 29 and Alligator Alley (I-75), and – although it is against the law – hunters also still shoot panthers occasionally.
The biggest threats to the remaining panthers, however, are their health and continuing loss of habitat. Florida panthers have an unusually large number of health problems. Most are related to poor habitat conditions and genetic defects.
Around the Everglades, panthers have been contaminated with mercury (at least 1 has died from mercury poisoning) by eating raccoons high in mercury, which passes through the aquatic food chain. The mercury’s origin is being debated and is uncertain.
What is being done?
Plans to save the panthers focus on 3 areas of action. First, additional habitat must be secured and enhanced. Second, programs are under way to breed panthers in captivity for later release back in the wild. Third, scientists are exploring ways to increase the genetic variability of panthers through cross-breeding with closely related subspecies.
The panther needs large wilderness areas for its survival. Federally listed as endangered since 1967, the Florida panther is down to 80 to 100 individuals. These few animals are threatened by further habitat loss, collisions with cars, the ill effects of inbreeding, and high levels of mercury in their prey.
May of the remaining panthers live in or near Big Cypress National Preserve and Everglades National Park. The National Park Service is cooperating with the U.S. Fish and Wildlife Service, the Florida Fish and Wildlife Conservation Commission, the Florida Department of Natural Resources, and other organizations to try to bring about recovery of the Florida panther. Efforts are centered on research, captive breeding, and public education. Radio-collaring of several panthers has shown what areas and habitat types they use. Other studies have identified the principal prey — white-tailed deer. Publicity has made the public more aware of the panther’s plight and alerted people to watch out for them on the highway. But with the numbers so low and suitable habitat in south Florida so restricted, captive breeding and reestablishment in other areas will be crucial for turning the population decline around.
Are There Any Refuges?
The National Wildlife Refuge System Act of 1966 includes measures to preserve ecosystems for endangered species, perpetuate migratory bird species, preserve natural diversity, and create public appreciation for wildlife protection.
The refuge system is administered by the U.S. Fish and Wildlife Service, an agency of the Department of the Interior. The Florida Panther National Wildlife Refuge is one of the 58 refuges established under the authority of the Endangered Species Act. The refuge area has long been known as an important Florida Panther habitat. Several female panthers have had litters and raised kittens on the refuge in recent years.
The Florida Fish and Wildlife Conservation Commission monitors panther activity using radio telemetry collars. They fly three times a week to aerially locate each radio-collared panther. These techniques provide vital information to scientists. The swamps and pinelands panthers occupy also provide us with clean air and water, as well as thousands of species of birds, mammals, reptiles and plants.
The Florida Panther National Wildlife Refuge lies 20 miles east of Naples, Florida. Interstate 75 parallels the south boundary; State Road 29 parallels the east boundary.
Mission of the Panther Refuge
To conserve and manage lands and waters in concert with other agency efforts within the Big Cypress Watershed, primarily for the Florida Panther, other endangered and threatened species, natural diversity,
and cultural resources for the benefit of the American people.
In 1989, data collected from 29 radio-collared panthers indicated that the population was losing genetic diversity at a rate of three to seven percent yearly. Researchers believed that the gene pool would continue to erode even if the population stabilized, leading to extinction within 40 years. Three years later, with the health of the population continuing to decline, biologists made a controversial decision. In an effort to increase genetic diversity, wildlife managers introduced several female Texas cougars — the closest remaining cougar population that had historically shared Florida panther range — into the Florida panther population in 1995. Several hybrid litters have since been produced, and the introduction seems to have corrected some of the problems experts generally attribute to inbreeding. Experts are still debating the role of the Texas cougars in panther recovery.
Despite the success of this effort, panthers are still at great risk of extinction. Conserving the panther will require aggressive protections for remaining wild lands in south Florida as well as conservation efforts on private lands.
Another major conservation challenge for the panther is reestablishing the species in other portions of its historic range. Field studies have indicated an adequate prey base and appropriate habitat in some areas of northern Florida. While there is widespread popular support for panther reintroduction in Florida, some people are still concerned about introducing the cat to new areas, fearing the panther will bring with it restrictions on private property uses, potential damage to livestock and pets, and a possible threat to human safety. Such concerns often surround recovery efforts for large carnivores, but with proper assurances to address depredation claims and any potential “problem” animals, reintroduction projects could prove a positive step towards recovering the Florida panther.
