Breaking up is hard to do – especially before Valentine’s Day. But for a team of animal care experts from Disney’s Animal Programs, saying goodbye often means a new beginning for the wildlife they’ve taken under their wing.
During the next few weeks, animal managers, veterinarians and behaviorists will wish farewell to dozens of endangered animals that will return to their native Florida habitat after spending weeks, months or even years with members of the Disney team. The animals range from a tiny, 11-ounce endangered rodent to a recently rehabilitated four-pound sea turtle to an eight-foot, 828-pound manatee. Whether flippers or feet, the common thread is that each one has received top-notch care as a reflection of Disney’s commitment to animal conservation and wildlife rehabilitation.
CRACKING THE CODE ON WOODRAT LOVE
Most recently, the animal care team collaborated with the U.S. Fish and Wildlife Service and Lowry Park Zoo on the first-ever reintroduction of 14 Key Largo woodrats to the Crocodile Lake National Wildlife Refuge in South Florida. The woodrats were bred at both Disney’s Animal Kingdom and Lowry Park Zoo in Tampa as part of a recovery plan to augment the existing population found only in Key Largo. Scientists estimate that this native species has dwindled to about 500 after years of habitat loss, drought and the invasion of non-native animal species, such as the Burmese python.
“Although small in size, the Key Largo woodrat plays a larger role in the circle of life,” according to Anne Savage, senior conservation biologist at Disney’s Animal Kingdom. “Through diligent study, we may be able to link these tiny rodents to the distribution of essential sources of food for other animals. That activity could facilitate the growth of fungus, trees and other fauna. That’s an important reason to be concerned about saving them.”
Prior to their release at Crocodile Lake National Wildlife Refuge, the Key Largo woodrats were placed in individual enclosures with nest structures designed and built by refuge volunteers. Supplemental food was provided for nearly a week while conservation biologists observed the animals in their new environment and felt comfortable removing the animals’ protective enclosures. Each animal has been fitted with radio-collared transmitter which will help scientists track their movements once released.
Breeding this elusive species was a challenge since scientists had very little information about social structure, reproductive biology or ecology. Through diligent research, Disney animal experts studied the behavior of this nocturnal animal and found ways to successfully breed 30 of the native species. Since June 2006, 18 litters have been born in Disney’s colony with litter size ranging from one to three pups.
Aside from scientific discovery, researchers develop special attachments to many of the Key Largo woodrats. “It feels similar to sending children off to college,” said Savage. “As scientists, we hope the woodrats have cultivated the skills to survive on their own and they will be successful in their natural habitat. It’s exciting to be part of this conservation effort and see them move on to their next chapter.”
LAKE BUENA VISTA, Fla., Sept. 23, 2009 – The Association of Zoos and Aquariums (AZA) recently recognized Disney’s Animal Programs for conservation efforts to help protect the endangered Key Largo woodrat. During the AZA’s annual conference, the team received the Edward H. Bean Significant Achievement Award, which recognizes programs that contribute to the reproductive success of a species.
Since 2005, Disney’s Animal Kingdom has been assisting the U.S. Fish and Wildlife Service in developing and implementing a recovery plan for the Key Largo woodrat, which is threatened by habitat loss along with an invasion of non-native animal species, such as the Burmese python.
During the very early days of the conservation program, animal researchers quickly learned that breeding this elusive species was a challenge since there was very little information about social structure, reproductive biology, or ecology. The Key Largo woodrats share little in common with the average city rat and are difficult to breed, having only about two litters per year of one to three pups.
Researchers also discovered that the nocturnal creatures also spend a lot of time building nests. “In the wild, Key Largo woodrats build stick nests that can be up to three feet tall,” said Andy Daneault, assistant curator of ectotherms for Disney’s Animal Programs.
Through diligent research, Disney animal experts found ways to successfully breed this nocturnal animal and have successfully bred nearly 30 Key Largo woodrats. The goal is to eventually reintroduce these captive-born woodrats to Key Largo to help increase the wild population.
