controlled burning

As a result, modern forest management now inlcudes 'controlled burning'.

It exists primarily as an understory plant in pine forests, and is sometimes stimulated by regular controlled burnings.

Fire ecologists like Ms. Antenen would like to see controlled burnings in such areas every 7 to 10 years.

In time, the species came to benefit from the indigenous peoples' periodic controlled burnings of the grasslands surrounding the Missouri to clear out old and dead growth.

Firefighters carried out controlled burnings the previous night around the groves to clear away debris from the forest floor that could otherwise fuel a fire to such an intensity that it dangerously licks at the trees' crowns.
