IMMOKALEE, Fla. - Since Florida's frontier days when cattlemen drove their herds through the state's vast fields and forests, ranchers and native panthers have been natural enemies.

The ranchers seek to nurture and protect their calves, while the panthers see them as prey.

Human development won the battle, driving the large, tawny cats to the brink of extinction before successful efforts to restore them began decades ago.

But with Florida's panther population recovering, some ranchers complain the protected 6-to-7-foot (about 2 metres) long predators are once again killing their calves.

Now, university research supports that claim, at least in one part of southwest Florida.

A University of Florida researcher hired by federal wildlife officials has found that panthers are killing calves in an area where the predatory felines are thriving. Her study, the first to quantify the kills and losses, was given to The Associated Press exclusively.

The research marks the first step toward the U.S. Fish and Wildlife Service considering a program that would pay ranchers for preserving acres of panther habitat, instead of undertaking the impossible task of verifying every kill.

"Ranchers will tell you that they suspected panthers were killing their calves, although no one knows how many they're losing," said Caitlin Jacobs, the university researcher who staked out a ranch for the better part of two years. "It's hard to find the calves — when panthers kill they drag the prey into the forest and cover it with brush to hide them from scavengers."

It's estimated that at one time, more than 1,300 panthers roamed Florida before their numbers dwindled — at one point in the 1800s, the state's government offered $5 for panther scalps. There were as few as 20 panthers in the 1990s, but the population has rebounded thanks to conservation efforts.

The problem began to draw the attention of state and federal wildlife officials about four years ago, after third-generation Florida rancher Liesa Priddy, owner of the 9,300-acre (3.6 hectares) JB Ranch, became suspicious when a new calf vanished.

Ranchers had been telling federal and state wildlife officials about the problem for years, but lacked scientific evidence. Calves are also commonly killed by coyotes, vultures and even bears.

In the past, ranchers simply would have shot the panthers, but because the state's 100 to 180 panthers are legally protected under the Endangered Species Act, they have few options.

Priddy had a local outdoorsman stake out her pasture with night-vision goggles. That night, a panther took a calf and they found the carcass, Priddy said.

She called out a state biologist, who confirmed it was a panther kill and began the research to find out how pervasive the issue had become.

The researchers targeted two ranches and tagged 400 calves on each. They found that JB Ranch, which has nearby forests where panthers can hide, lost 10 calves, or about 5 per cent. A beef cow can go for around $1,000. A lost heifer can cost future profits from breeding more cows.

The other ranch lost only one calf to panthers over that time.

The study's results are set to be released later this year. The information can help wildlife managers move forward on ideas for compensating ranchers.

Right now, small ranchers with less than 100 head of cattle can apply for compensation from two nonprofits: Defenders of Wildlife and Conservancy of Southwest Florida.

But those programs aren't used by bigger ranches, Godsea said, and don't have the resources to address the larger problem.
