In total, 137 areas in 34 countries were identified as most important for preserving. Many are already designated under UNESCO's World Heritage Convention, but more than half are not, including the most irreplaceable site, Colombia's Sierra Nevada de Santa Marta Natural National Park. The park is home to a number of endemic and endangered species. Then there are sites such as the Párramo Urrao National Protective Forest Reserves, which Paul Salaman, CEO of the Rainforest Trust, said in a statement does not even exist as a protected site in practice, only in name. It's expected that protected areas—which make up 13 percent of the land on Earth—would be, as the name suggests, protected. But for various reasons, that's not always the case.
