What is the term for an area of unburned land surrounded by burned land?

The term "island" is used to describe an area of unburned land that is completely surrounded by burned land. This terminology is commonly employed in wildfire management and firefighting contexts. An island can occur during a wildfire when certain environmental conditions prevent the fire from spreading to a particular section of land, effectively creating a patch of unburned terrain relative to the larger burned area surrounding it.

Understanding this term is crucial for firefighters and land management professionals as it can impact strategies for controlling wildfires, assessing damage, and planning future land use. Identifying islands can help in determining areas that may still require protection or could serve as safe zones during firefighting operations.
