Pull a tooth. Measure the rack. Weigh the
moose. Reach for a comb?
No matter what you think you saw in
Greenville on Monday, Morris — the state’s moose specialist —
was not giving free makeovers to moose with that comb.
She was conducting important research state
officials hope will help them better understand the Maine moose
herd.
Specifically, Morris was counting ticks.
"We don’t have any ticks on our moose,"
80-year-old Fredrick Douglass of Richmond Corner said after
being told what Morris was looking for.
Douglass was wrong.
His moose had plenty of ticks … and so did
most of the other moose that were tagged.
"The concern is that some of these moose have
thousands and thousands of these things on them," Morris said.
"They take a lot of blood out of moose. It’s looking very much
like it could be a primary mortality cause for moose in some
years, in some areas. We’re suspicious that we’re losing calves
in some years."
Wally Jacubas, the DIF&W’s mammal group
leader, said a young moose with thousands of ticks on it can
struggle during harsh Maine winters.
"The moose, they don’t try to get rid of the
ticks really until it is too late," Jacubas said. "They start
rubbing on trees and rubbing a lot of their hair off. Of course,
the hair of a moose is a great insulator, and with that gone,
they’re going to expend a lot more energy than they normally
would trying to keep warm."
If a moose has also lost a lot of blood, or
is ill or old, it can end up dying, Jacubas said.
Morris and Jacubas said a student at Unity
College did a special project on moose and ticks and developed a
method for DIF&W personnel to spot-check for ticks at four sites
on a moose’s hide, then extrapolate that data to estimate a
total tick load.
In addition, Jacubas was looking at full
hides that had been skinned and donated at the Greenville
tagging station, checking much more carefully.
Moose are affected by winter ticks, not the
deer ticks that sometimes carry Lyme disease, Jacubas said. The
winter ticks are not known to cause health problems in humans,
he said.
After the research is completed, Morris said
the state will have more available data to answer some key
questions. Among those: Does the state’s estimated carrying
capacity — the maximum number of moose that can live in a given
area — need adjustment?
The state has set population goals for the
moose herd, but those goals may not even be possible, Morris
said.
"We’re thinking [a certain density of moose]
may just be something that we can’t attain, or we can attain
only briefly, and then the ticks would reduce [the herd size],"
Morris said. "That’s the real thing: To evaluate whether or not
the goals for the moose population make sense."
Morris explained that the more moose are in a
given area, the more likely the ticks are to survive and thrive.
"Because there are more moose [in an area],
there would be more ticks that make it through the winter and
are sitting around out there this time of year, ready to hop
onto another moose," she said.
And if ticks are in fact becoming a primary
mortality source when a certain moose density is reached, the
state wants to know about it.
"If [ticks are reducing the herd size and
keeping it from reaching the state’s goals], we’re restricting
hunting opportunity for no reason, to try to allow a moose herd
to increase," she said.
Jacubas said he’s not sure what the actual
effect on hunters would be and didn’t know whether the state
would increase permits or leave the number the same.
Both Morris and Jacubas agreed that studying
the situation was a necessary first step.
"We dropped [the number of] cow permits
because sighting rates were going down and people said they
wanted more moose," Morris said. "And sighting rates started
going up again. Unfortunately, our changing harvest rates, and
some anecdotal information we have on tick numbers, and also
studies from New Hampshire suggest that we don’t know whether it
was our management or the ticks [that led to the change]. It
just happened at the same time.
"So [studying ticks in the Maine herd] would
be something we’d want to look at just to get a better picture
of how the whole thing is fitting together."
Tewksbury deserves credit
In Tuesday’s editions I told you about the
hunting success of Wally Staples, who bagged an 820-pound moose
while hunting on Monday morning.
A clarification is necessary: Master Maine
Guide Luke Tewksbury of Kennebec Valley Guide Service in Bingham
did the advance legwork and scouting for Staples, who lives in
Durham.
And when Staples said, "We actually had [the
moose] on videotape" from two weeks earlier, he was referring to
the video that his guide, Tewksbury, had captured during those
scouting trips.
