Rob and Mike-
This is Lowell Miller's new GnRH one-shot, IC vaccine for deer.
from. Lowell for use in cH given our poor success with Spayvac
We need a commitment from the donor or the community to do anything more with deer in the village.Our fawn counts will be completed soon. -pDC
Study examines new contraceptive for deer
Sunday, July 10,2005

Star-Ledger Staff
A deer herd on the Giralda Farms business campus in
Morris County is going to be the target of a
contraception study aimed at a new one-shot,
longer-lasting method of deer birth control, a
potential aid to controlling deer overpopulation in
towns and neighborhoods where hunting is not an
option.
The research effort, approved this month by the state
Fish and Game Council, will be conducted by
Connecticut-based White Buffalo Inc. on the 30g-acre
Madison and Chatham Township site, a suburban location
about a mile from downtown Madison.
It is part of a larger study being conducted by the
federal National Wildlife Research Center, aimed at
getting approval for use of a Gonadotropin-releasins
hormone, simply known as GnRH.
One shot of the drug could provide three to five years

of^sterility, and possibly even a longer-lasting
effect if a deer is injected a second iime. said
researchers.
Kathleen Fagerstone, research manager for the National
Wildlife Research Center, said the experimental drug
could be used to deal with the problem of deer
overpopulation in suburban New Jersey neighborhoods.
Buthunting also will remain a key tooi for managing
herds in more wide-open areas, she said.
"There is a big misconception out there about this
project," she said. "This will not replace hunting,
which is a very good deer management techniqie."
Th..""y drug caught the attention of Morris County
Freeholder Director Jack Schrier, a former member of
the Fish and Game Council, who said it might have
benefits for his county's 39 towns, many of-which are
seeking to control growing whitetaii herds.
Schrier scheduled a July 27 briefingfor his board by
Fagerstone and White Buffalo president Anthony
DeNicola. In cooperation with the county park
Commission, he also set up a seminar later that day at
the Frelinghuysen Arboretum in Morris Township for
municipal officials and other interested persons.
"This is an issue that affects people throughout
Morris County profoundly and will continue to do so
unless we find an altemative to hunting," said
Schrier, who admittedly dislikes deer hunting to cull
herds, though concedes it has a place in the overall
solution.
Schrier wants his board to take the lead in the state
in urging federal officials to set aside at least $5
million annually for intensive research and swift
development of a practical, safe, long-lasting deer
contraception formula and one-shot method to deliver
it. Such a discovery could especially benefit more
densely populated towns, such as Mendham Borough and
IJanover, that arc oveffun with deer but cannot easily
or safely permit hunting in residential areas, he
said.
A resolution proposed by Schrier states: ,,High
densities of deer have created near-emergency
situations, causing deer-vehicle collisions resultins
in death and injuries, ecological damage to native
species of woodiand flora, gardens and agricultural

crops, as well as elevated risk of Lyme disease, all
of which costs our citizens and farmers more than $50
ry1tti9n annually and places their health and safety atrisk."
The National wildlife Research center has studied deer
conlraception since the early 1990s. It developed G'RH
and hopes to get a patent on it, said Fagerstone.
Be_fore it can get approval from the U.S. Food and DrugAdministration, however, it has to complete two
separate research studies. One is now under way by the
-agelcy in Maryland and a second independent study will
be done at Giralda Farms.
The studies will take at least two years and the
approval process will continue for an unknown period
after that, she said.
Fagerstone, in a written report, explained GnRH is
part of apathway that signals the 6ody to produce sex
hormones. It is produced by the hypoihalahus, a major
organ in the brain. Without GnRH, verv little
estrogen, progesterone, or testosterone are produced.
The aim of a GnRH vaccine is to bind to oi "tie up"
the GnRH produced within an animal's body so that it
does not trigger reproduction, she wrote.
The potential has piqued the interest of state
wildlife experts.
"This could be a useful tool, especially for confined
areas," said Len Wolgast, a member of the Fish and
Game council and a former Rutgers university wildlife
professor- "The big problem witri immuno-contraception
is the delivery system.
"You've got to be able to get the right dose to the
right number of deer at the right agi and right time
of year."
White Buffalo will have a controlled settine on the
grounds of Giralda Farms -- which is surroinded bv
eight-foot fences -- to try and answer those questiois
and study the effectiveness of the drug.
