The heavy smoke drifting into the Jacksonville area Saturday crept in from a large prescribed burn to reduce wildfire risk on the Rogue River-Siskiyou National Forest this fall.

In all, 600 acres was burned in the Siskiyou Mountains district to improve deer habitat in the French Gulch and Doe Hollow areas.

The burn was ignited by a "helitorch" — a torch mounted to a helicopter that drops flammable material.

Benefits from the burn will include stimulating sprouting and germination of fire-adapted plant species while discouraging growth of non-fire adaptive species.

Prescribed burning will be used to reduce wildfire risk and improve habitat on more than 4,700 acres on the Rogue River-Siskiyou National Forest this fall and early winter.
