BILLINGS, Mont. (AP) — Climate change, voracious beetles and disease are imperiling the long-term survival of a high-elevation pine tree that’s a key source of food for some grizzly bears and found across the West, U.S. officials said Tuesday. A Fish and Wildlife Service proposal scheduled to be...

SALEM, Ore. (AP) — Deadly West Coast wildfires are dividing President Donald Trump and the states' Democratic leaders over how to prevent blazes from becoming more frequent and destructive, but scientists and others on the front lines say it's not as simple as blaming either climate change or the...

The U.S. Fish and Wildlife Service says there's enough scientific evidence that two rare plants in Nevada's desert could go extinct to warrant a year-long review of whether to list them as U.S. endangered species, including one at the center of a fight over a proposed lithium mine.

In this Aug. 4, 2019 photo provided by Taylor Williams, a new species of seaweed covers dead a coral reef at Pearl and Hermes Atoll in the remote Northwestern Hawaiian Islands. Researchers say the recently discovered species of seaweed is killing large patches of coral on once-pristine reefs and is rapidly spreading across one of the most remote and protected ocean environments on earth. A study from the University of Hawaii and others says the seaweed is spreading more rapidly than anything they've seen in the Northwestern Hawaiian Islands, a nature reserve that stretches more than 1,300 miles north of the main Hawaiian Islands. The algae easily breaks off and rolls across the ocean floor like tumbleweed, scientists say, covering nearby reefs in thick vegetation that out-competes coral for space, sunlight and nutrients.

PORTLAND, Ore. (AP) — A team of retirees that scours the remote ravines and windswept plains of the Pacific Northwest for long-forgotten pioneer orchards has rediscovered 10 apple varieties that were believed to be extinct — the largest number ever unearthed in a single season by the nonprofit Lost...

WASHINGTON (AP) — Dog detectives might be able to help save ailing citrus groves, research published Monday suggests. Scientists trained dogs to sniff out a crop disease called citrus greening that has hit orange, lemon and grapefruit orchards in Florida, California and Texas. The dogs can detect...

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)

MISSOULA, Mont. (AP) — A study of grazing in Yellowstone National Park found that bison essentially mow and fertilize their own food. This allows them to graze in one area for two to three months during the spring and summer while other hoofed mammals must keep migrating to higher elevations to...

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds. Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts...
