what is levonorgestrel According to the U.S. Department of Agriculture, sometime after World War II, one reptile stowaway, a female brown tree snake, possibly pregnant, probably slithered off a ship and onto the island of Guam. Over the next 60 years, the offspring of that founding mother snake, in the absence of natural predators, have flourished to excess. Guam today is evidently awash in brown tree snakes - one to two million of them. And while the problem is interesting, it's the solution to this problem that caught our attention, the plan that USDA and other agencies are using to pull a St. Patrick and rid the Pacific island of its snakes. Dan Vice is a biologist with Wildlife Services - it's a USDA agency. He's in Guam and has worked on this project for over a decade. Welcome to the program.
