If you see smoke in the air in Clay County, don't worry. The St. Johns River Water Management District is conducting a 63-acre prescribed burn Thursday.

The burn is going to be at the Black Creek Ravines Conservation area.

The purpose of the burn is to reduce hazardous fuels and maintain pyric ecosystems, according to a press release.

Prescribed burns are planned out. "Its benefits include restoring and maintaining natural communities, reducing chances of destructive wildfires, perpetuating fire-adapted plants and animals, cycling nutrients, controlling tree diseases, and opening scenic vistas. Prescribed fires help prevent wildfires by burning off fuels that naturally build up over time, while also helping to control the growth of woody shrubs," according to the press release.
