PORTLAND, Ore. (AP) — Lightning has touched off a wildfire in grass and brush south of Steens Mountain in southeastern Oregon, just north of the Nevada border.

The U.S. Bureau of Land Management said Friday the fire is burning in an area of about 3,000 acres, or nearly 5 square miles. The agency said it's threatening sage grouse habitat.

There's sparse human presence in the area, and the bureau said the fire isn't threatening any of the ranches.

It's called the Denio (di-NY'-oh) Basin fire.

Lightning on Thursday was also blamed for a smaller fire on private land near Drewsey, along U.S. 20 east of Burns. The bureau said firefighters kept it from spreading to government lands.
