Summary of Reviewed Fraser Island World Heritage Values
This report is the result of a comprehensive review undertaken by
the Fraser Island World Heritage Scientific Advisory Committee in
conjunction with other scientists. Peer review of this paper has not
been completed at the time of going to press.
This report contains a review of the World Heritage value of the Fraser
Island World Heritage Area. World Heritage listing is based upon
overall Outstanding Universal Value and this report
represents a consensus of the opinions of a range of scientists
selected for their first hand scientific knowledge and experience of
the values of Fraser Island which together form this overall
Outstanding Universal Value. The report is based upon individual
interviews with these scientists and a group workshop held to
discuss the values, attributes and threats.
The assessment of World Heritage value has been based on the criteria
for World Heritage listing. These have changed since the original
listing of Fraser Island and it was decided to use the new criteria,
thus ensuring that the review would look at whether, and in what
aspects the property would meet the requirements of the Convention
today. The project has identified attributes and key locations which
demonstrate the values under each criterion as well as threats to
these and has made assessments of the condition of integrity (as
applied in the Convention).
Natural Criterion (i) Ongoing geologic and geomorphic processes
The various landscapes formed on the sandmass of Fraser Island are
outstanding examples of major stages in the development of coastal
dunes in the subtropics during the Holocene and Late Pleistocene. As
at Cooloola, they also provide a chronosequence in soil development
and in dune degradation by water erosion. Coeval with the dune
formation is the formation of many of the freshwater lakes. This
process resulted in numerous dune lakes, probably half of the worlds
complement, many of which are perched. In the west of the island,
there are excellent examples of at least two stages in the
degradation of vegetated dunes by water erosion and the development
of a fluvial drainage net. All of the preceding processes are ongoing
and Fraser Island exhibits several stages in their development.
The dunes and dune lakes are generally robust and the threats are limited
providing that the dunes retain their protective vegetation cover.
There is some concern regarding infilling of lakes and streams by
sand washed from nearby roads. Overall the Fraser Island property
meets the conditions of integrity for this criterion however is
should be noted that a more complete dune chronosequence could be
captured by the inclusion of the Cooloola sandmass.
Natural Criterion (ii) Ongoing ecological and biological processes
The infertile sandy soils of Fraser Island support a diversity of plant
communities ranging from colonising plants and open woodlands to very
tall eucalypt forests and rainforests to low, shrubby heath. The
distribution of these communities across the island landscapes is
intimately related to the distribution of the soils that have
developed on the various dune systems. The Fraser Island and Cooloola
dunes together provide at least nine windows in time that show
progressive stages in plant succession, including changes in
floristics and structure and increasing biomass, followed by stages
of decline as access to nutrients decreases (retrogressive
succession). Each of these stages has a particular assemblage of
species adapted to the nutritional conditions of the site. These
processes of ecosystem development and maturation as well as species
sifting are continuing. The soil fauna assemblages are not well known
for any of these ecosystems but research at Cooloola implies that
there is a similar correspondence between these and the dune system
chronosequence.
The nature and distribution of the attributes that support this criterion
are such that it is robust and not threatened as a whole. The
integrity of the present World Heritage property is satisfactorily
captured by the present boundaries such that the majority of the
attributes that contribute to the World Heritage value are contained
within it. Local degradation can occur from the effects of excessive
numbers of visitors, inappropriate fire management and the invasion
of exotic species and pathogens.
Natural Criterion (iii) Natural phenomena and areas of exceptional natural beauty
Fraser Island was inscribed on the World Heritage List in 1992 under
Criterion (iii), and it was the unanimous position of workshop
delegates that the outstanding international status of associated
attributes continue to support the assessment made in 1992. The large
scale of Fraser Island and its diversity of landscape elements with
vistas and sites of exceptional beauty are of world quality.
The diversity of ecosystems and habitats developed on the sandy substrate
contribute to world class opportunities for aesthetic appreciation.
The unique atmosphere of the Island and a sense of awe
capture visitors and wonderment is generated through interaction with
a world of quartzose sand. These subjective feelings are
promoted, developed and enhanced through interpretive presentation of
the World Heritage Values of the property, and contribute to a
powerful visitor experience. Consequently, there was consensus at the
workshop that addition of aesthetic importance to
Criterion (iii) substantially strengthens the rationale for listing
under this criterion.
In terms of integrity, Fraser Island, as an essentially self-contained
entity, is large enough to include and preserve the diversity of
landscape elements that contribute to the outstanding aesthetic value
as defined by the attributes supporting this criterion. It was,
however, the feeling of the workshop that inclusion of adjacent sand
passages, estuaries and islands would serve to reinforce the
integrity of the World Heritage Area. From a purely aesthetic point
of view, the relevant boundaries would be the limit of visibility.
The overall scenic beauty of the site was not considered to be
compromised by current human activities. Some localised degradation
of amenity has resulted from identified threatening processes. These
include the physical and social impacts associated with increasing
visitor numbers, continuing development within Island communities,
existing fire regimes, introduction of invasive plants and pathogens,
and development of management infrastructure and visitor
restrictions. There was, however, consensus within the workshop
group that all of the identified threats are currently being, or have
the potential to be, ameliorated through pro-active and effective
management. The site has a current and effective management plan and
receives institutional protection through Commonwealth and State
nature conservation and biodiversity legislation. It may be
concluded that the overall integrity under Criterion (iii) has
changed little since the positive assessment in 1992, and that both
the management and legislative status have improved since that time.
Natural Criterion (iv) Biodiversity and threatened species
According
to Dr Richard Lindsay, President of the International Mire
Conservation Group, the patterned fens of Fraser Island and Cooloola
are globally unique. They are the only sub-tropical patterned fens
and the only fens flowing into tidal wetlands in the world and they
have distinctive faunal inhabitants such as fish, crayfish and
earthworms that would not normally be found in such acid
environments.
Fraser Island has distinctive assemblages of biota many of which demonstrate
unusual characteristics associated with living in a sandy and acidic
environment. Fraser Island, in common with Cooloola, has a number of
rare and threatened species, including the newly discovered monotypic
genus of sand-burrowing skink Coggeria, and the island
is an important stronghold for a number of species that are declining
on the mainland.
The extensive satinay (Syncarpia hillii)/brushbox (Lophostemon
confertus) forests present on Fraser Island represent the best
and most extensive stands of this forest type in the world. Together
with the blackbutt (Eucalyptus pilularis) forests and
rainforests, these tall forests are remarkable for the sheer biomass
of trees growing on a quartzose sand substrate. The rainforests also
contain relict Gondwana flora, such as Araucaria and Agathis
and several primitive plants.
The Great Sandy region as a whole is a lake district of world class. The
lakes are particularly well developed on Fraser Island while Cooloola
has more extensive heathlands and the Noosa River and its associated
tidal lakes. Perched dune lakes are rare elsewhere but there are
more than 40 such lakes on Fraser Island, including the largest in
the world. The number, diversity and relatively undisturbed state of
these lakes makes Fraser Island an outstanding research area for
understanding dune lake ecology.
Fraser Island is part of a system that maintains an internationally
significant population of trans-equatorial migratory waders.
Although much of the RAMSAR site is outside the present World
Heritage area there is limited but important habitat for these
species within the 500m World Heritage boundary off the Islands
western shore.
In terms of integrity, Fraser Island is the largest remaining area of
vegetation developed on the aeolian sands in southeastern Australia.
Together with Cooloola, it represents the stronghold for the
distinctive flora and fauna associated with these nutrient-poor,
acidic, sandy soils. It is of sufficient size to maintain viable
populations of all of the significant species found in the area. The
area is almost entirely within an existing national park. Being an
island it is, to some extent, isolated from impacts of surrounding
land use, invasion of exotic pests and diseases and similar pressures
on the natural values of the area.
A number of current and especially potential threats to the attributes
listed under this criterion were identified, varying with the nature
of the attribute. Inappropriate fire management was seen as a threat
on a broad scale, whilst the impacts of visitors were seen as a
significant threat on a more local scale at some sites (especially
lakes and streams).
This summary of Fraser Islands World Heritage values is a
result of an extensive review involving the leading scientists in a
position to contribute to identifying all of the special values of
Fraser Island and Cooloola. The process of reviewing the values was
overseen by the Fraser Island Scientific Advisory Committee. It
included interviews a workshop and further review by the Community
Advisory Committee and the Management Committee. The comprehensive
document detailing the process and the values was still being
undergoing rigorous peer review when this summary went to press. It
has been agreed that the primary objective of management is to
protect these values.
Cultural Criteria (iii) and (v) relating to the
cultural landscape
The Committee and workshop
participants recognised that there is a need for the traditionally
affiliated people to have an opportunity to present their cultural
values of Fraser Island through a culturally appropriate process.
The workshop working group recognised this need and offered its views
in a positive spirit in this context.
Present knowledge indicates that Fraser Islands cultural landscape is
at least of national significance. A key component of this
significance is the size of the intact landscape and its relatively
undisturbed nature. Large scale examples of human interaction with
the landscape before the modern era are increasingly hard to find,
particularly coastal examples. This scale is very much enhanced by
the intact and extensive Cooloola sandmass landscape to the immediate
south. It is also likely that the cultural record will be
significantly enhanced as more research is carried out, this was
certainly the case at nearby Cooloola. Thus the significance of the
Fraser Island cultural landscape is likely to continue to grow.
Considered
in the context of the Islands natural values, the Fraser Island
cultural landscape adds significantly to the propertys
outstanding universal values, although in itself it is unlikely to
qualify the area for World Heritage listing based on present
knowledge.
In
terms of authenticity, the overall landscape of Fraser Island is
still relatively intact with modern intrusions being confined to a
limited number of small townships. Elsewhere, the built environment
generally takes the form of sand tracks and low level visitor
infrastructure, such as toilets and viewing platforms. The skyline
is essentially free of towers and transmission lines. There are large
tracts of pristine or near pristine landscape and each of the
components of the landscape has high quality undisturbed examples.
Members of the workshop cultural heritage working group were of the
view that participants in the Eliza Fraser story would be readily
able to recognise the landscape of today. Overall there is a high
degree of authenticity to the landscape over large areas encompassing
examples of most of the identified components. The key threats to
this authenticity were seen as a changed fire regime on a broad
scale, and inappropriate buildings and incongruous activities on a
more local scale.
Cultural Criterion (vi)
inspiration for outstanding artistic and literary works
The
citing of Patrick Whites work from Fraser Island in conferring
a Nobel Prize is a clear independent assessment of its international
cultural significance and value. The works of Sir Sydney Nolan and
Peter Sculthorpe further add to the body of significant works
inspired by Fraser Island. With such works having been produced in a
relatively short time and with easier access to the area for the
creative talents of today and the future the likelihood of further
major works is clear.
The
landscapes that inspired the works are largely intact and as such, a
visitor appreciating the works can have access to an authentic rather
than modified experience. In this regard the size and extent of the
landscapes are important as well as any specific localities.
As
with Cultural Criteria iii and v, Fraser Island is unlikely to
qualify for World Heritage listing under this criterion however the
attributes identified do enhance the natural values of the property
as identified under the natural criteria.
The review process unanimously concluded that Fraser Island and
Cooloola together represent outstanding universal value for a coastal
sand system environment that is substantially enhanced beyond that of
each property separately.
