[From the text] In the southeastern United States, the native biota of many natural ecosystems are adapted to periodic burning. It is generally believed that in Florida at the time of European intervention, these ecosystems were sustained as fire climax communities by relatively…

Fire-maintained pine barrens once covered more than 20,000 hectares in the Albany region on sand deposits associated with glacial Lake Albany. Today, urbanization and fire suppression have reduced the area to less than 1,000 hectares of pine barrens, which are dissected by…

Man began an intensive program to keep fire out of the woods about 70 years ago. Periodic ground fires once common in western pine forests were reduced, and a stand type that had been open, thrifty, and fairly resistant to wildfires lost those characteristics. The current status…
