There are a total of  54 different species of martens. The Humboldt marten is one among the same family. Marten species are found everywhere except in Australia and Antarctica. Humboldt species of marten were considered extinct until they were rediscovered in the year 1996. In the year 2010, the Center for Biological Diversity and Environmental Protection and Information (EPIC) filed for a petition to protect this member of the weasel family. Apart from this the U.S. Fish and Wildlife Service too announced that they would provide special protection to such species. After a decade they were given protections as threatened species under the federal Endangered Species Act. Tierra Curry, a senior scientist at the Center for Biological Diversity, was extremely delighted to know this. They also were recognized by the U.S. forest service.

Humboldt martens are forest carnivores which makes them unique since most species of martens are known to be classified as omnivores like the pine marten another subspecies. In this article, we will take a look at some fun and interesting information on the unique Humboldt martens. If you like this article then check out gopher facts and naked mole-rat facts.
