14. To burn or not
to burn? Fire is a common, natural force in most plant communities in Florida
including scrub habitat and many types of wetlands. Scrub habitat burns
approximately every 15-80 years. Fires that happen frequently will
result in a type of scrub, often without sand pines. If fire occurs less
frequently another type of scrub develops with mature sand pines. Under
natural conditions fire would burn through sand pines, killing the sand
pines. At this point the cones would release their seeds to start the
cycle over. Without fire, these communities will develop into an
unnatural condition with a loss of animal and plant diversity.
Prior to restoration efforts, large sand pines dominated this area.
Because of the surrounding development, the likelihood of a fire
occurring was remote and unsafe.
Since a fire would have been extremely dangerous with the sand pines in
place, the first step was to harvest the sand pines to reduce the amount
of fuel. To simulate fire, four primary methodologies were used to
restore the site: controlled burning, root raking, roller chopping and
harvesting.
