Helicopter Logging’s Bumpy Ride
Using helicopters to thin
forests instead of fighting fires
By Bob Bruce
Helicopter
logging, or helilogging, is a technology that fills an important niche in the
forest products industry. It provides an environmentally-sensible way to remove
trees with minimal impact while at the same time bringing to market previously
un-harvestable timber.
Arrival in the 70’s In the early
1970s, the growing environmental movement combined with heavy-lifting
helicopters developed for the military in Vietnam, made helilogging an
attractive and practical alternative. Today, the Helicopter Association
International estimates there are nearly 175 forestry or logging companies
worldwide that use helicopters as a significant or primary means of removing
timber from the forest. Because of the unique capabilities of helicopter logging
rigs, virtually all helilogging operations focus on areas unreachable by
conventional ground access means because of extreme slope, environmental
sensitivity, or simply their remoteness from roads. The only real drawback — as
heliloggers themselves admit — is the cost. When you figure in equipment costs,
maintenance, flight crew, ground support crew, etc., it’s not beyond reason to
peg the helicopter portion at around $5,000 per hour, with the overall cost of
helilogging at from 20 to 30 percent higher than traditional ground-based
logging.

such a pristine environment, the hydraulic fluid on the equipment on the
barges was replaced with environmentally friendly canola based oil. Fully
laden barges were towed to regional mills. |
Columbia Takes Off
One of the first companies to get into helilogging was Columbia Helicopters,
home-based at the Aurora Airport in Aurora, Ore. Columbia was founded in 1957 by
Wes Lematta. After Wes was mustered out of service from WWII, he used the GI
Bill to go to flight school and get his helicopter flight certification. Then
with his brother Eddie, he bought a used Hiller 12B — a 1950s era 2-seater
widely used by the Army and Navy as a trainer. Columbia started out selling
helicopter rides at county fairs, but in just two years were able to add two
more ‘copters to their fleet as well as pick up a contract to lift and place
power poles over the rugged terrain of rural Oregon. The job required both
precision and safety, so Wes developed a pilot-side bubble that allowed the
pilot to essentially lean out over the side of the helicopter to get a more
direct view of the attachment line and the target zone. The improvement worked
so well that it became a standard feature on virtually all helicopters used for
long-line pickup and placement jobs. When the heavy-lift Sikorsky S-58 (the Army
Choctaw) and the more powerful S-61 (the Navy Sea King) became available in the
late 1960s, Columbia was poised and ready to enter the helilogging business.

Ups and Downs Over the Decades
Max Merlich, VP of Logging Operations, has been with Columbia since 1976 and has
seen changes in the industry up close. “The market was good back in 1976,” said
Merlich. “The environmental movement was gaining strength and that drove the
logging industry to find a more environmentally-sensitive way to do business.”
In the decades since, logging on public lands has taken a serious nosedive due
to what some might call overzealous environmental restrictions. Today, loggers
say that the selective thinning made possible by helilogging is vital in order
to pull timber from remote stands without having to build access roads. But
environmentalists are upset precisely because helilogging can reach into areas
previously too difficult and uneconomical to log.

The Necessity of Thinning
Merlich sees a certain contradiction of logic to the argument: “There is a
tremendous amount of thinning that absolutely needs to be done if we are to
maintain forest health. People in rural areas understand that, but those in
urban areas don’t seem to get it. In the Suislaw National Forest alone, for
example, there’s 350 to 400 million board feet of growth each year. We’d have to
thin 5 to 10,000 acres each year just to keep up.” All over the Pacific
Northwest public forestlands are becoming too thick for their own good. While a
lushly overgrown forest may be fun to hike through, if you take a few years of
summer drought conditions and mix in a couple of good electrical storms, the
result is likely to be a raging inferno that gets out of hand way too quickly.
That’s something the members of the White Mountain Apache Tribe in Arizona know
all too well.
Last year’s Rodeo/Chediski fire
consumed close to 467,000 acres, much of it on tribal land. That same year saw
the Biscuit Fire in Southern Oregon, which burned about 500,000 acres. Either
one might have been slowed or minimized had there been an active thinning
program in place. But now that they’ve happened, the next big public policy
challenge according to Merlich is to clear the way for salvage efforts before
the firedamaged timber becomes completely unmarketable. “According to a fellow
from OSU,” said Merlich, “there is 4.2 billion board feet of salvageable wood at
the Biscuit Fire burn, with 2.2 billion board feet within two miles of a road.
That’s a lot of wood. The problem is they have just one or two years to get it
out and they haven’t done anything so far except wring their hands and worry
about it.” The situation is a bit better at the Arizona burn, but challenges
remain because of the size of the salvage area, the fact that it has involved
winter operation, and because most of the logs have to be trucked to sawmills in
California. Even so, said Merlich, “Fire salvage and bug kill are traditionally
areas where heliloggers have been able to perform well and make some money,
because they are situations where you are under time constraints to move a lot
of wood.”
High and Low-Tech Operation
Working a job like the Rodeo/Chediski salvage requires a sizeable crew and some
intense coordination. Columbia has five helicopters on the job with their flight
and support crews, a fully-stocked parts and repair depot, an overall manager, a
forest engineer, five siderods, and bullbucks under them. It’s a five-sided
operation and all personnel keep in touch with FM radios, cell phones, and a
satellite Internet link at the service landing. Despite the cell phones and
laptops, Merlich wouldn’t characterize the operation as particularly high-tech.
“Our equipment is very well maintained, but ‘copters are all old technology. You
can’t afford to just buy a new helicopter; you have to modify older equipment.
And while there is some potential for using mechanical equipment on the end of
the cable . . . a certain part of logging is always going to require manpower.
On a steep hillside you still have to have somebody go up and cut the trees;
there’s no other way to do it.” Columbia rounds out its ground fleet with
equipment from Komatsu and Cat. Their primary loader is a Komatsu PC300HD, and
they also run Komatsu 270s, 380s and 450s. They also have a couple of Cat 330
shovels as well as Cat 966s and 980s. “We run the machines a long time,” said
Merlich, “maybe 15 to 20,000 hours, but we maintain them very well. There’s
never going to be a better loader than the Cat 966C, but the problem anymore is
you can’t get landings big enough to run them on so we’ve had to go more to
shovels and that more than doubles your cost.”
Logging Over Burns
Overall, Columbia has remained successful even in the face of industry rough
spots, by building a tightly-organized structure where nearly every aspect of
helilogging is taken care of in-house. “Everyone in the industry is struggling
to make a living today,” said Merlich. “We have seen some bankruptcies, some
consolidations, but we are optimistic about the future because we think there
are political changes afoot. The number one problem is lack of work due to the
market and the failure of government to salvage fire and bug kill. Columbia put
a lot of time and money into getting Bush elected and we are trying to get this
Bush Healthy Forest Initiative rammed through so we can get to work and get the
job done.” In the meantime, until thinning and salvage activity picks up to a
level where Merlich and many others feel it should be, firefighting work is
(unfortunately) a growth industry. “Firefighting has been strong for the last
three years,” said Merlich, “and it is very lucrative.” He admitted, though,
that he would rather be logging timber before it burned, rather than after. TW
