The Lesser Antilles Iguana has disappeared on many other islands and is an endangered species in St Barth. Part of the problem on St Barth is that they are breeding with the more dominant green iguana, and several hybrid iguanas have been spotted. The green iguana is not native to St Barth and was brought there via St Maarten. They are larger and more territorial than the Lesser Antilles iguana. The problem with the hybrids is that they are thought to be sterile. In addition, the iguana faces many other menaces. The island has many cats and dogs who love to chase and kill the iguanas, although they don't eat them. Rats eat the iguana eggs, and the goats eat everything in sight, leaving nothing for the iguanas to feed on. Mankind is also contributing to their declining numbers. The increase in construction results in fewer and fewer isolated places for the females to lay their eggs. They have also been killed by cars when crossing the road or resting in the road to enjoy the sun. So, be on the outlook for an iguana in the road and give it time enough to move.
