While the red shoulder hawks went about their courtship and
nest building activities, a roseate spoonbill soared overhead on a cool January
morning. I was in the hydric flatwoods in SW Florida, a moist area filled with
tall pines and carpeted with saw palmettos that appeared to have just been
trimmed. I was getting a glimpse into the timeline of this ecosystem’s life and
into our own awakening as responsible citizen scientists.
It was now January
and a fire had occurred here in August. Just before the fire, understory plants
such as salt bush, wax myrtle, grape vines and blackberries were beginning to
compete with the saw palmettos and dead leaves were thickening the floor. Grasses
and wildflowers were being shaded out. The fire that had burned here six months
before was called a prescribed burn set by the land managers from the South
Florida Water Management District, the primary landowner and one of the
partners participating in the Corkscrew Regional Eco-system Watershed or CREW. CREW
is the largest intact watershed in SW Florida encompassing 60,000 acres,
which contains a 5,000 acre sawgrass marsh, headwaters for the entire watershed, including
the Audubon Society’s Corkscrew Swamp Sanctuary. The CREW Land &Water
Trust is the private, non-profit partner that helps to coordinate land acquisition,
management and public education and outreach.
The people of CREW
have formed a working relationship with the land, so much so, that a paradigm
shift is developing. They are beginning to call themselves stewards, a term
that more accurately defines their role as caretakers in relationship with the
land through conservation and sustainable practices. My appreciation for the
work that all members of the Trust do is immense, including their efforts to
share their knowledge and recruit more citizen scientists.
We are a part of this landscape; not apart from it. As citizen scientists, we can focus our
interaction through observation and hands on learning. Through the CREW Trust’s
education programs, citizens are being called to participate in these fires so
that they too can witness the transformative properties of fire and learn how
to conserve and sustain the Florida landscape. On this day I was reminded that
this ecosystem evolved with fire and that we need to live with fire if we are
to maintain healthy plant and animal life. Fire has always been a part of this
environment, having transformative powers on the local landscape. Burning
allows the carbon and other nutrients bound up in the over growth and leaf
litter to be released back into the soil, controls insect pests and diseases,
and improves the quality and quantity of forage plants. Within this stand of pine
forest, the hope was that the burn would allow grasslands to remain open at the
edge of older pines perhaps creating suitable habitat for the rare Red-cockaded Woodpecker.
Setting a burn every one - two years would also create a
habitat favorable for ground foraging birds, while a three - five year burn
will encourage understory plants suitable for turkey and deer. In another area
the decision to allow the pines to develop into a hardwood hammock was
evidenced by the emerging smaller oaks and the Yellow-bellied Sapsucker
sampling them all. This succession into a hardwood hammock will bring another
diversity of species, contributing to the variety of habitats that evolved with
this land.
I saw that this activity is both a science and an art form.
Land stewardship involves reading the land and making decisions about the
succession timeline. The variables for
determining when and where a fire needs to be set are many. They consider the
time of year, every detail about the weather, plants and animals, as well as
educating partners in the burn, which can be many volunteers. Safety is always
on their minds. Wait too long for a prescribed burn and the resulting wildfire
could be catastrophic, burning so hot as to wipe out the forest entirely and
threaten homes. The demonstration burn this day was a small one set against the
oncoming wind referred to as a back burn. This patch of palmettos and cabbage
palms had been overrun by the understory plants and leaf litter. Within just a
few minutes after setting the fire the brush was gone and green still remained
on the tips of the palms. With the passage of time, I will report on the
wonders that I find there.
