Wildfires that break out in Yellowstone National Park this summer will be fought from the outset until the nation's controversial let-burn policy is evaluated by a government panel, the park's chief ranger says.

Dan Sholly said the National Park Service is under a directive by the Department of Interior to suppress all fires until a review of the policy allowing natural fires that are not threatening structures or lives to burn in national parks and wilderness areas."We hope by 1990 we'll be back into a fire management progaram and out of fire suppression," Sholly said during a panel discussion at the Idaho Wildlife Federation conference in Sun Valley.

The suppression directive ewas ordered by former Interior Secretary Donald Hodel following last summer's massive fires, which charrred more than 5 million acres in parks nationwide, including nearly 1 million acres in Yelowstone National Park.
