Problems in SC
& Marine WG
読売新聞
• Government promised to Fishers
Associations not to make further
regulation for World Heritage
• IUCN requested further
conservation efforts.
• SC’s solution:
– Increasing effort for
conservation by fishers
– Describe management plan as
fishers are doing.
– Expand area including shelf

IUCN "Report of the reactive monitoring mission 18-22 February 2008
Modified dam on Iwaubetsu River
•The mission team also applauds the bottom up
approach to management through the
involvement of local communities and local
stake-holders, and also the way in which scientific
knowledge has been effectively applied to the
management of the property through the overall
Scientific Committee and the specific Working Groups
that have been set up. These provide an excellent
model for the management of natural World
Heritage sites elsewhere.
http://whc.unesco.org/en/list/1193/documents/ 8
Missions of the SC
• Describe and evaluate voluntary management of
coastal fisheries as they do
• Okhotsk stock assessment of walleye pollock and
make a stock recovery plan
– Using spawners, catch and CPUE including Russian data.
• Build relationship with Russian scientists and …
• Examine effects of sapling of salmonids on wild
population and fisheries
• PVA of sea lions based on responsible data

IUCN Review Report
Criterion II Ecosystem processes
Shiretoko provides an outstanding
example of the interaction of marine
and terrestrial ecosystems as well as
extraordinary ecosystem productivity,
largely influenced by the formation of
seasonal sea ice at the lowest latitude
in the nor-thern hemisphere. This
process supports the formation of
phyto-plankton, the primary producer
in the marine ecosystem and provides the source of food for marine
and terrestrial species…
10
IUCN Review Report
Criterion IV Biodiversity
Shiretoko has particular importance for a
number of
marine and terrest-rial
species. These include a number of
endangered and endemic species, such as
the Blackiston’s fish owl and the plant
species Viola kitamiana. The property is
globally important for salmonids, marine
mammals, including the Steller’s sea lion
and cetaceans. The property has
significance as a habitat for globally
threatened sea birds and is a globally
important area for migratory birds….

Walleye pollock problems for
Total Allowable Catch (TAC)
• Russia exploit this fish by big
trawl nets
• Lack of data in Russian waters
• Do not exploit spawning fish
too much

IUCN’s Technical evaluation
5.3 Neighbouring Islands
There are clear and apparent similarities between the environment and ecology in Shiretoko
and the neighbouring islands. It is noted that
there has been contact between Japanese and
Russian researchers. Should it be possible for
the States Parties to agree to promote the
conservation of these properties
in the future, there may be the
potential for development of
these properties as a wider
“World Heritage Peace Park”.

Fishers utilize many species, monitor these stocks.
FCAs regulate fishing efforts and zones.
FCAs decrease boats by their own compensation.
Fishers may play an umbrella species (we monitor
fishers to evaluate health of ecosystem)
Sustainable fisheries based on healthy ecosystem
Government has to monitor non-target species and
global environment
Consensus should be build among not only fishers but
also processors, consumers, and environ-mental NGOs.
Scientists consult and support these consensus.
