Dozens of insectivores around the world are threatened, according to the World Conservation Union (IUCN). Thirty-six are listed as Critically Endangered, facing an extremely high risk of extinction in the wild. Forty-five are Endangered, facing a very high risk of extinction in the wild, and eighty-eight are Vulnerable, facing a high risk of extinction in the wild. In the United States, only the Buena Vista Lake ornate shrew is listed as Endangered by the U.S. Fish and Wildlife Service.
Habitat destruction has proven to be the biggest danger to these species. As humans clear forests, farm more land, and use toxic chemicals to control plants and animals, populations of these small animals can be destroyed.
