Crews drop more than 1,000 tons of hay to prevent more damage after last year's Trinity Ridge Fire

BOISE NATIONAL FOREST, Idaho (KBOI) - Last summer, the Trinity Ridge Fire ripped through nearly 147,000 acres in Idaho, charring the Boise National Forest.

This year, the Forest Service is trying to prevent even more trouble. But this time, it's not to do with fire.

Crews are rehabilitating parts of the forest to keep down the risk of flooding and erosion that comes with summer thunderstorms.

"We've lost our tree canopy, and we've lost our soil cover at the ground, which are the two main factors that help with rain drop intercept," said a spokesperson for Boise National Forest.

So forest workers are dropping wheat straw over 1,200 acres of burnt land. They're dropping the hay from helicopters.

The Forest Service says dropping the straw will help stop flash flooding from happening this summer.

"By treating this, we're hoping to minimize erosion coming off the hill slopes, getting into the water and affecting the water quality and fish habitat, the forest's spokesperson said, "The treatments are intended to protect our values at risk, which are human life and safety, our roads and culverts and water quality, and important cultural and natural resources."

The project has been ongoing for about a week and a half, and it concludes Sunday. It costs around $800,000.
