US national parks face 'crisis' over invasive animal species

Dec 3, 2019

Invasive animal species represent a crisis for United States national parks, experts have said, in a call for widespread, systemic action.

More than half of national parks are threatened by invasive animal species, but the threat has gone unaddressed, according to a new paper.

The panel of experts said coordinated efforts and partnerships would be essential for success.

The paper was published in the journal Biological Invasions.

National parks span more than 85 million acres and can be found in all 50 states. They are home to the country's most beloved natural wonders and well-known historic sites. Since 1916, more than 400 parks have been established for protection.
