The largest mammal in North America, the Bison, joins the ranks of the Bald Eagle as the official national mammal of the US. The bison was added to the list after President Barrack Obama signed the National Bison Legacy Act on May 9.  

 

Though the political debates in the US are highly polarised these days, but on the issue of voting for the bison as the national mammal, there was widespread agreement among the lawmakers.

 

The bison has a lot of historical and cultural significance in the life of Americans. Once almost instinct, it is also a symbol of successful American wildlife conservation. The supporters of this move believe that making bison the national mammal will also mobilise larger support for the ongoing conservation efforts to save the bison

 

The giant, agile and vegetarian mammal were found in abundance once upon a time in the Great Plains of the continent. Now largest population can be found in the Yellowstone National Park, where these giants have been living since pre-historic times. Across the US, they are now cross-bred and partially domesticated.
