Just as certain plants
need fire to
succeed, the animals
that depend
on those species
benefit from fire as well.
It was my first prescribed
burn. After weeks of training, and
months of anticipation,
I was finally on the ground — drip
torch in hand — ready
to apply fire to restore the mixed
pine-hardwood forests
at the edge of the Blue Ridge
Mountains, on the
Grandfather Ranger District of
Pisgah National Forest.
Joining the Forest Service only two months
earlier, I
had a mainly academic knowledge of fire's
effect on
plant and wildlife communities. As the
coordinator
for the Grandfather Restoration Project,
part of the
Collaborative Forest Landscape Restoration
Program,
I had to come up to speed with the on-the-
ground
reality of prescribed fire use quickly.
In the Forest Service's Southern Region,
prescribed
fire is a key tool for management and
restoration of
fire-dependent ecosystems. The
Grandfather Ranger
District, with its south-facing piney
slopes, has a
historic fire return interval of 5-7 years.
Today, the
return interval is 10-fold the historic
record,
averaging 50-70 years across the
district.

As I lit the fire that early March morning, igniting
the
thick leaf litter and dense shrubs that
accumulated
with years of fire suppression, I couldn't help
but wonder:
What happens to the wildlife after the fire?
Replacing
the fuels with scorched earth is unnerving
to those who
are not familiar with fire as a restoration tool,
with the
aftermath often being likened to a
"moon-scape."
The reality is much different. Just as
certain plants
need fire to succeed, the animals that
depend on
those species benefit from fire as well.

"Prescribed fire burns at varying intensities across the
landscape, creating abundant soft mast, grasses and
forbs, a reduced shrub layer, and small canopy gaps,"
said Pisgah National Forest Wildlife Biologist Chris
Williams. "These conditions provide foraging, nesting,
and escape cover for a variety of game and non-game
terrestrial wildlife."
With the evolving use of prescribed fire as a tool for
restoration, it is critical to study the effects of fire on
the communities we are looking to restore. Traditional
fire studies often focus on vegetation.

decided take it one step further — to directly study
wildlife use in sites that are treated with prescribed fire
compared with untreated sites.

Working collaboratively, wildlife specialists from
Pisgah National Forest, the North Carolina Wildlife
Resource Commission, and The Nature
Conservancy designed a cutting-edge study using
wildlife cameras.

Re-entering the prescribed burn unit just four months
after the fire, wildlife cameras in tow, I could see the
changes in vegetation. From a so-called "moon-scape"
just after the burn, a lush herbaceous layer had
appeared, carpeting the forest with blueberries and
grasses.
Using 50 camera points over a six-week period in July
and August, we were able to study which wildlife
species are using our forests, and what habitats they
prefer. Cameras captured deer, bears, turkeys and
other wildlife.

"I was very encouraged by the effects of the burn,"
Williams said. "While the results of the study have
not been fully analyzed, the photos can provide land
managers with population estimates
" predator-prey ratios."

Early data indicates a higher use of the burn unit by
wildlife when compared to the unburned unit. More
solid results will be available as the data is analyzed
over the next several months.
