On the introduction of wolves to Shiretoko in Hokkaido
=
The international conference of mammalogy was held in Sapporo
by Shiretoko-Hokkaido and Yellowstone
national park, bickered over protection of ecosystem. “Wolf controver=
sy
“ remains as far apart as ever, because Japan countered U. S’.s proposal of reintroduction(of wolf) and in=
sist
that “wildlife management must be improved primarily.

According to the report of Shiretoko-foundation
“World heritage Shiretoko and
Yellowstone”, which released in this spring, carnivorous animal was u=
sed
to be exterminated in Yellowstone, and wolf became extinct in 1926. However
31wolves was taken from Canada in 1995－=
;1996, because they are expected the effec=
t that
its reduce mule deer and elk. Wolf increased about 180 at the moment, on the
other hand, elk decreased about 1700－=
;less than 10000 in the north of the park.=
And
also riverside forest begin to recover, wild bird and beaver increased too.=

Professor emeritus Dale Mackallow(University of Califo=
rnia)
proposed the experimental introduction of wolf as useful things for Shiretoko which
they experienced in Yellowstone.
Ezo wo=
lf in Hokkaido disappe=
ared
until 1890. Ezo deer is increasing recently, th=
ere
are 10000 deer in Shiretoko. The trees in wood =
died down,and that have an effect on grassland-vegetation.=
However professor Kohichi
Kaji(Tokyo University of Agriculture and Techno=
logy)
says “Considering possibility, Recovery of wolf is not realistic̶=
1;.
Yellowstone has 885 people who relate park management, on the other hand Shiretoko has only 70 including environment ministry =
and
NGO stuff.,though U.S. argued over wolf for 10 years.
Shiretoko-foundation’s general lab worker Ma=
sami
Yamanaka says “ the improvement of backward wildlife management is top
priority while we need wolf in order to recover original nature. That
doesn’t become a reality until we can make the base of reintroduction=
