FILE - In this Aug. 3, 2016 file photo, a herd of bison grazes in the Lamar Valley of Yellowstone National Park in Wyo. A study of grazing in Yellowstone National Park found that bison essentially mow and help fertilize their own grass. This allows allowing them to feed in one area for two to three months during the spring and summer. Researchers say they found that large numbers of bison grazing in one area stimulates the growth of nutritious grasses and keeps the area greener longer. (AP Photo/Matthew Brown, File)

An international conservation group is warning that more than half of the trees in Europe that exist nowhere else in the world are threatened with extinction. The International Union for the Conservation of Nature says in their latest assessment of Europe’s biodiversity that 58% of the 454 trees species native to the continent are threatened, and 15% are “critically endangered” - one step away from extinction.
