burnable

If all burnable material on the ground has been removed, a fire should run out of fuel when it reaches a fireline.

Question marks dot the landscape of burnable bushes and pushable boulders, with entire regions left unrevealed.

“Use good judgment and don’t light a fire close to burnable vegetation or overhanging branches,” Starkovich said.

Across burnable lands globally, the annual number of flammable nighttime hours increased by 110 hours over the past four decades — allowing five additional nights when flammability does not cease, the study stated.

A statistically significant decline in such nights happened in 59% of burnable lands worldwide.
