DescriptionA considerable amount of experience and knowledge has been gained in the application of growing-season burning in pine communities across the Southeast. However, there is still concern that burning during this season will cause increased tree mortality and/or growth loss. Pine flatwoods stands in south Florida with 3 years of fuel accumulation were burned during the growing season using rather aggressive head-firing techniques. Crown scorch ranged from a low of 16 percent to a high of 83 percent. The lowest crown scorch occurred on treatment units burned mostly with flanking fires. Although scorch was quite high in some units, mortality was not significantly increased by growing-season burns. The probability of mortality and growth loss can be minimized by using firing techniques that produce less intense burns and by avoiding burns during the late growing season or when trees are already stressed.
