Shawn Davis told Channel 2's Tom Regan she spotted one slithering down her hallway and another in a fruit bowl.

"The first was a baby copperhead; the second was a rat snake. My husband said since the last two snakes, he found two more. But he didn't want to tell me about it, cause I'm a nervous wreck," Davis said.

Residents first contacted Channel 2 Action News about the problem in September. They reported sightings of a half-dozen snakes, including a six-foot-long copperhead that was trapped in an apartment breezeway and killed.

Davis and her husband, Paul Patterson, said they repeatedly reported their concerns to management and requested moving into another building but were told that was not possible.

Earlier this week, they filed a lawsuit accusing apartment management of negligence in failing to control the population of venomous snakes. The suit seeks unspecified damages.

As much as 99 percent of Haiti has been deforested over the past few decades, as the country’s desperate people have cut down trees to make way for agriculture or charcoal production. This massive habitat loss has put the entire nation’s biodiversity at risk. Only a few untouched habitats remain.

The La Hotte land frog’s habitat is one of those areas. "It’s a very beautiful forest," (Carlos) Martinez (Rivera, amphibian conservation biologist with the Philadelphia Zoo,) says. "There are a lot of tree ferns, pines and magnolia trees. It feels like going to any other tropical rainforest. But it’s a very tiny patch of forest." The trees are still being cut down to produce charcoal or to clear land for cash crops such as parsley, celery, broccoli and carrots.

With so much of the country already deforested and more trees likely to be lost in the coming years, the Philadelphia Zoo in 2010 set out to save some of Haiti’s endemic frogs that live in those fading forests. They captured 154 frogs from nine species and brought them back to Philadelphia to establish a captive breeding program. "You can protect wildlife like frogs in a small space," says the zoo’s chief operating officer, Andy Baker. "Trying to keep a genetically viable population of tigers takes the entire global zoo community, whereas in a relatively small room you can hold a genetically and demographically viable population of an entire species of frog. Our return on investment on species protection for animals like reptiles, amphibians and invertebrates can be very high."
