Florida Panther

Florida Panther

The Florida Panther is one of the 32 different subspecies of Cougar and is the only remaining subspecies on the East Coast. The Florida Panther is an endangered big cat species that can have males weighing between 100-159 pounds. They have tan colored fur with a white belly along with black spots on the end of its tail and ears. It currently only lives in the swamps and forests of South Florida even though it used to occupy areas throughout the Gulf Coast extending into Arkansas and parts of Tennessee and South Carolina.

One of the main reasons for this species decline was that a bounty was put on them in 1832 because they were seen as a threat to humans and livestock, which lead to the killings of thousands of panthers. This, coupled with habitat loss has lead to the dwindling numbers of wild Florida Panther and has caused them to become endangered.
The main threats to the survival of the Panther today are mostly all associated with habitat loss and how little land they have to survive on. Since they do not have that much habitat, there is not enough land for their population to grow back to a healthy, sustainable level. A male panther can have territorial claims for 200 square miles and a female for 75 square miles so they need a lot of land to sustain a healthy population. Since there population is so small (only 100-160) left they are losing genetic diversity from inbreeding, resulting in a loss of fitness in Florida Panthers (picture from http://intra.burltwpsch.org/). This makes them more susceptible to diseases such as feline leukemia virus which is almost always fatal and causes the panthers to have poorer health overall. Even collisions with cars are a major problem for the panthers, which killed 20 panthers in 2014. When there population is just over 100 panthers, losing just one panther is bad, let alone twenty. However there is hope for the Florida Panther because there are plans to increase their population and get them off the endangered species list.
Since Panthers need so much land, the main goal of the restoration plan is to “maintain, restore, and expand the panther population and its habitat in south Florida”. This will be done by expanding the panther population north of the Caloosahatchee and by reestablishing viable panther populations outside of Florida by finding habitat that is suitable for a panther population to be introduced. To help the panthers with their loss of genetic diversity, a genetic restoration program was established.(http://www.fws.gov/southeast/news/2008/images/FloridaPantherGenet98A5BCF.pdf) Since, the Florida Panther used to be able to breed with other subspecies of cougar, there lack of contact with other subspecies today has led to inbreeding and a loss of genetic diversity. To fix this, people reintroduced 8 female Texas Panthers, which are the closest subspecies to the Florida Panther, into South Florida. These females mated with the local panther population and created many offspring, which tripled the panther Florida Panther Population as a whole. This has helped with the loss of genetic diversity due to a small breeding population and has increased the health of the Florida Panther population.

The Florida panther will also be left on the endangered species list until there are three, self-sustaining populations of 240 panthers for at least twelve years in a row. If everything goes as planned and there are no speed bumps in the restoration process, then the Florida Panther could be moved from endangered to threatened in 30 years and completely delisted in 45 years.
