The Golden Toad of Costa Rica as the Canary in the Mine of Climate Change and Mass Extinction
A beautiful little amphibian called the Golden Toad was first described in the Monteverde mountain region of Costa Rica in 1966, but has not been seen anywhere in the world since 1989 and is presumed to be extinct. This biological tragedy is made more alarming by the fact that this region of the Costa Rica mountains is protected as a national reserve and was presumed to be a site for species preservation, not extinction! Costa Rica has some of the most delicate and unusual ecological systems of the world. Placed at the isthmus of the junction between North and South America, Costa Rica has both a Pacific and a Caribbean coast, with a prominent North-South mountain range that serves as a continental divide, which, like that in North America, determines whether rivers flow to the Pacific or Caribbean oceans. Monteverde is near a unique regional preserve in the mountainous region North of San Jose, the main city of Costa Rica (To get there you have to drive up a 30 km road that is unpaved, very rocky and dangerous. We did it in a small four-wheel drive car, during an intense rain storm, but most others we met hired tour guides to take them up and bring them back: they looked at us like we were a little nuts).
