ALTITUDE Sea-level to 20m
PHYSICAL FEATURES Shark Bay comprises a series
of north-south facing peninsulas and islands which separate inlets and
bays from each other and the Indian ocean. The coastline is 1,500km long
and includes the 200m high Zuytdorp cliffs, which are amongst the highest
of the Australian coastline. There are three distinct landscape types:
Gascoyne-Wooramel province which comprises the coastal strip along the
eastern coast of the bay and consists of a low-lying plain backed by a
limestone escarpment; Peron province which comprises the Nanga/Peron peninsulas;
Faure Island/sill comprising undulating sandy plains with gypsum pans
or birridas, and ancient interdune depressions filled with gypsum. The
seaward margin of this province terminates in a scarp 3-30m high and narrow
sand beaches; Edel province which comprises Edel Land peninsula and Dirk
Hartog, Bernier and Dorre Islands, is a landscape of elongated north-trending
dunes cemented to loose limestone. The province terminates to the west
as a series of spectacular cliffs (DASETT, 1990).
The basement rock in the area is Late Cretaceous Toolonga
limestone and chalk. The most extensive younger rocks are Peron sandstones
and Tamala limestones (the offshore islands are composed of the latter).
These rocks are often overlaid by a series of longitudinal fossil dunes
accumulated during the Middle to Late Pleistocene (for further details
see DASETT, 1990). The extensive supratidal flats of Gladstone Embayment,
Hutchison Embayment and Nilemah Embayment are comparable to the coastal
'Sabkhas' of the coast of the Arabian Gulf. Gypsum has been formed as
a result of evaporation of saline groundwaters within the sediments of
broad tidal flats adjacent to areas such as Hamelin Pool. Shell beaches
occur at the southern end of Lharidon. The inland terrestrial landscape
of Shark Bay is predominantly one of low rolling hills interspersed with
birridas (inland saltpans that are at sea-level). Shark Bay itself is
a large shallow embayment, approximately 13,000 sq km in area, with an
average depth of 9m (maximum of 29m). The bay is enclosed by a series
of islands. Influx of oceanic water is through the wide northern channel,
the Naturaliste channel, between Dorre and Dirk Hartog islands and South
Passage between Dirk Hartog Island and Steep Point.
The outstanding feature of the bay is the steep gradient
in salinities. The salinity gradient ranges from oceanic (salinity 35-40
ppt) in the northern and western parts of the bay through metahaline (salinity
40-56 ppt) to hypersaline in Hamelin pool and Lharidon bight (salinity
456-470 ppt). The salinity gradient has created three biotic zones that
have a marked influence on the distribution of marine organisms within
the Bay. Tides vary with a spring range of 1.7m and a neap range of 0.6m.
The Leeuwin current sweeps past Shark Bay, an intrusion of warm low-salinity
tropical water of great zoological significance. The interaction of wind
drift with tidal currents leads to a Bay circulation in which overall
movement is anticlockwise from west to south-east, then east and finally
north-west (DASETT, 1990).
Two rivers drain into Shark Bay, including the intermittent
flows of the Gascoyne and Wooramel River into the eastern part of the
Bay. There is very little surface run-off because of the low rainfall,
high evaporation and permeable soils. There is active regional saline
groundwater flow, however, and some freshwater springs, such as in the
intertidal zone north of Monkey Mia (DASETT, 1990). There is a large quantity
of artesian water approximately 300m below the ground surface.
CLIMATE Shark Bay has a semi-arid to arid climate
characterised by hot dry summers and mild winters. Summer temperatures
average between 20°C and 35°C and winter temperatures between 10°C and
20°C. Average annual precipitation is low, ranging from200mm in the east
to 400mm in the far southwest. Annual high evaporation ranges from 2000mm
in the west to 3000mm in the east.
Sea surface temperature outside the Bay varies from
20.9°C in August to 26°C in February. Within the Bay water temperatures
vary; in the inner bay temperatures drop to 17°C in August. In February
a maximum of 27°C has been recorded in Hamelin Pool, 26°C in Freycinet
Reach and 24°C in the oceanic salinity zone. The Leeuwin Current flows
along the West Australian coastline and greatly influences the temperature
of seawater in the bay.
VEGETATION The flora consists of a transition
of the South-west Botanical Province to the Eremaean Botanical Province
and more than 620 species have been recorded for the entire Shark Bay
region, 145 at the northern limit of their range, 39 at their southern
limit and 25 considered rare or threatened at the national level (DASETT,
1990).
The South-west Botanical Province consists of vegetation
that is rich in Eucalyptus species, forming woodland with diverse,
shrubby understories and heathlands poor in grasses. The Eremaean province
is correspondingly rich in Acacia species but has large areas dominated
by grasses, especially prickly hummock grasses of the genera Triodia and
Plectrachne. The Province includes shrublands of Acacia ligulata,
Pimelea microcephala and Stylobasium spathulatum. Vegetation
on the older dunes includes Melaleuca cardiophylla, Thryptomene
baeckeacea and Plectrachne bromoides (for further details see
DASETT, 1990).
Mangroves occur in small, relatively isolated areas
in southern and western Bay, only becoming abundant towards Carnarvon.
The southernmost extensive stand of white mangrove Avicennia marina
occurs on the Peron Peninsula (Anderson, n.d.). The marine flora is dominated
by seagrass beds covering 4,000 sq. km. Twelve species of seagrass occur
in the Bay: the most abundant species is Amphibolis antarctica,
covering 90% of the seagrass bed area, providing a substratum for 66 species
of algal epiphyte. Halodule seagrass beds occupy an area of approximately
500 sq. km.
Shark Bay is notable for benthic 'living fossil' microbial
communities, forming an expansive and wide variety of microbial mats,
which are best developed in Hamelin pool, giving the area the most significant
assembly of phototropic microbial ecosystems in the world. These photosynthetic
prokaryotes and analogous eukaryotic microalgae, which commenced growing
in the Pool when it first formed about 4000 years BP, trap and bind detrital
sediment and thereby create organo-sedimentary microbialites or microbial
mats, which have mineralised to form stromatolites in Hamelin Pool (see
DASETT, 1990 for details; Fox, 1991; Collins, in litt., 1990).
FAUNA The Shark Bay region is an area of major
zoological importance, primarily due to the isolation of the marine and
terrestrial ecosystems over significant periods of time. The Bay is located
near the northern limit of a transition between temperate and tropical.
For example, of the marine fish species 83% are tropical, 11% warm temperate
and 6% cool temperate.
Of the 26 species of threatened Australian mammals,
5 are found on Bernier and Dorre islands; burrowing bettong Bettongia
lesueur, rufous hare-wallaby Lagorchestes hirsutus, banded
hare-wallaby L. fasciatus, Shark Bay mouse Pseudomys praeconis
and western barred bandicoot Perameles bougainville. Greater stick-nest
rat Leporilus conditor has recently beenintroduced on Salutation
Island. In 1992, burrowing bettong was introduced on Heirisson Prong,
and was followed with the release of Shark Bay mice in June 1994. Shark
bay is renowned for its marine fauna, with 10,150 dugong Dugong dugon
(V) (Marsh, H., pers. comm., 1991). Humpback whale Megaptera novaeangliae
(V) and southern right whales use the bay as a migratory staging post.
Bottle-nosed dolphin Tursiops truncatus can be seen at Monkey Mia.
A minke whale was stranded on shore in 1981 and killer whales Orchinus
orca were sighted attacking dugongs at Sandy Point in May 1983 (Anderson,
n.d.; DASETT, 1990; Fox, 1991).
The rich avifauna includes over 230 species, with 11
breeding marine birds including osprey Pandion haliaetus and Caspian
tern Sterna caspia, for which Failure Island is a key breeding
area. Over 35 Asian migratory species occur in the region and four of
these breed in Shark Bay. A number of birds reach their northern limit
in the Bay including regent parrot Polytelis anthropeplus westralis
and western yellow robin Eopsaltria australis griseogularis (for
a full species list see DASETT, 1990).
Shark Bay is noted for the diversity of its herpetofauna,
and supports nearly 100 species. It is rich in 'old Australian elements'
with 12 species of diplodactyline geckos and 12 species of pygopodid lizards.
Several characteristic species include leptodactylid Neobatrachus wilsmorei,
hylid Cyclorani maini, gecko Diplodactylus squarrosus, skinks
Egernia depressa, Lerista muelleri and Morethia butleri,
and the monitors Varanus brevicauda, V. caudolineatus, V.
eremius and V. giganteus. Green turtle Chelonia mydas
(E) and loggerhead turtle Caretta caretta (V) occur in the bay,
nesting on the beaches at Dirk Hartog Island and Peron peninsula. The
islands, peninsulas and gulfs provide a refuge for nine relict or endemic
species: pygopodids Aclys concinna major, Aprasia haroldi
and Pletholax gracilis edelensis, skinks Ctenotus youngsoni,
C. zastictus, Egernia stokessi aethiops, Lerista maculosa
and Menetia amaura. Shark Bay supports populations of at least
six sea snake species including the endemic Aipysurus pooleorum
(DASETT, 1990).
Shark Bay is also an important nursery ground for crustaceans,
fishes and coelenterates. The marine flora is dominated by seagrass beds
providing a substratum for 100 species of zoophytes, juvenile fish and
sea snakes. There are 323 fish species. Large numbers of sharks including
bay whalers, tiger shark and hammerheads are readily observed in Shark
Bay. There is also an abundant population of rays, including manta ray.
Because of the high organic productivity and development
of seagrass beds and carbonate sand flats, the shallows of Shark Bay support
a benthic invertebrate fauna of exceptional abundance, diversity and zoological
significance. The invertebrate communities of Shark Bay remain essentially
unstudied (see DASETT, 1990 for further details).
Coral reefs are present, although they are not abundant,
with over 80 coral species. Hermatypic or reef building corals are found
in South Passage and there are large patches along the east coast of Dirk
Hartog, Bernier and Dorre Islands (Anderson, n.d.). The initiation of
the Leeuwin current coincides with the mass spawning of hermatypic corals
and is believed to be a major factor in the distribution and maintenance
of coral communities in the region. In addition, of the 218 species of
bivalve in the region, 75% have a tropical range, 10% a southern Australian
range and 15% are west coast endemics (DASETT, 1990).
CULTURAL HERITAGE The record of aboriginal occupation
of Shark Bay extends to 22,000 years BP. At that time most of the area
was dry land, rising sea levels flooding Shark Bay between 8,000-6,000
years BP. A considerable number of aboriginal midden sites have been found,
especially on Peron Peninsula and Dirk Hartog Island which provide evidence
of some of the foods gathered from the waters and nearby land areas. The
mild climate favoured permanent residence.
Shark Bay was named by the English buccaneer William
Dampier in the late 17th century. It is the site of the first recorded
European landing in Western Australia, with the visit of Dirk Hartog in
1616, followed by William Dampier in 1699. The landing of Dirk Hartog
on 25 October 1616 was commemorated by a pewter plate nailed to a post
on the northern tip of Dirk Hartog Island, Cape Inscription (Doak, 1989;
Fox, 1991). By virtue of its position, the area was a key navigation aid
for navigators and explorers at this time. In 1712 the ship Zuytdorp
of the Dutch East India Company was wrecked offshore and the French ships
Uranie and Physicienne, commanded by Captain Freycinet,
visited and studied Shark Bay in 1818. After 1850, the Shark Bay region
was variously occupied by guano miners, pearlers, fishermen and pastoralists.
Pearling was the biggest industry from 1850 until its decline in the 1940s
to be replaced by fishing. The fishing industry peaked in the 1960s and
has declined over the last two decades with the introduction of regulations
introduced to prevent over-exploitation of fish stocks (DASETT, 1990).
In 1904, until abandoned in 1911, quarantine hospitals
were set up for aborigines with leprosy and venereal disease on Bernier
and Dorre islands. After World War Two, a whaling station was located
at Carnarvon, and between 1950 and 1962 up to 7,852 humpback whales were
killed. The station collapsed in 1963 due to a lack of whales (DASETT,
1990).
Since the 1960s interaction of man and wild dolphin
groups have occurred regularly in Monkey Mia on Shark Bay's Peron peninsula,
the only known interaction on a regular basis in the world, a cultural
heritage which parallels similar accounts from North Africa as described
by Pliny the Younger in about 109 AD (Edwards, 1988; Anderson, n.d.).
LOCAL HUMAN POPULATION Shark Bay has a population
of approximately 750, principally located at Denham (population of 450)
and Useless Loop (Fox, 1991). Some of the local residents are of aboriginal
descent (Anderson, n.d.).
The economy of the region now includes tourism, fishing,
and pastoralism. The residents of Carnarvon (located just outside of the
bay area) are partially reliant on the fishing industry established in
Shark Bay. The area is fished by 27 boats of the prawn fleet with a harvest
reported to have stabilised at 2,000 tonnes over the last 20 years (WAFIC,
1991). Scallop fishery catches average at 3,500 tonnes per year from the
14 boats based at Carnarvon. The Shark Bay fisheries have a capital investment
of approximately Australian $80 million, employing 500 people in the region.
The fisheries harvest approximately Australian $35 million per year (WAFIC,
1991). In the 1960s salt evaporation works were established at Useless
Loop, and a gypsum mine (now defunct) (DCLM in litt, 8 February 1996)
on Edel Land (Anderson, n.d.; DASETT, 1990).
VISITORS AND VISITOR FACILITIES Tourism is important
and more than 160,000 visitors per year are estimated to visit Shark Bay.
The figure is increasing as a consequence of easier access with the construction
of new roads, motels and hotels. One of the greatesttourist attractions
of the region is sport fishing for which a number of fishing tours and
charter vessels exist (Anderson, n.d.). Nearly all visitors (100,000 per
year) come to see a group of wild bottle-nose dolphins which has been
coming regularly to feed and interact with people at Monkey Mia beach
for more than 30 years (Edwards, 1988). In 1986 an information centre
was constructed at Monkey Mia in conjunction with the Shire of Shark Bay.
The Department of Conservation and Land Management (CALM) has developed
visitor facilities at Hamelin Pool, Shell Beach and Francois Peron National
Park and provides a wide range of interpretive literature about the World
Heritage Area (DCLM in litt. 8 February 1996).
SCIENTIFIC RESEARCH AND FACILITIES Scientific
specimens were first collected in 1699 by William Dampier on Dirk Hartog
Island. In 1801, the naturalist Francois Peron, during the Baudin Expedition,
made important observations on the marine fauna and made plant collections.
Subsequently, the naturalists Quoy and Gaimard collected zoological specimens
in Captain Freycinet's voyage to Shark Bay. Between 1818 and 1822 Phillip
Parker King made the first comprehensive charts of the region for the
Royal Navy (Fox, 1991). A summary of recent research in the Shark Bay
area was produced in 1990 by the France-Australe Bicentenary Expedition
Committee (Berry et al., 1990).
CONSERVATION VALUE Shark Bay is a complete marine
ecosystem containing many important features, including the Wooramel seagrass
bank, the Faure sill and ecosystems dominated by benthic microbial communities
which flourish in the hypersaline embayments, and living fossil stromatolites.
Other features include a diversity of endemic and threatened plant and
animal species and areas of great natural beauty.
Shark Bay contains the most diverse and abundant examples
of prokaryotic stromolitic microbialites in the world, the world's best
example of three-dimensional grazing stomatolites (Collins, in litt.,
1991). The Hamelin pool occurrence of these microbial ecosystems offers
the only extensive living analogue for comparable studies with Proterozoic
stromatolites which yielded information of the nature, palaeoenvironment
and evolution of the Earth's biosphere until the early Cambrian period.
Modern examples including coccoid cyanobacterium which are thought
to be descendants of a 1,900 million year old form, thus representing
one of the longest continuing biological lineages known (DASETT, 1990).
The only other major microbialite occurrences in the world are in Lake
Clifton in Western Australia and Lee Stocking Island in the Exuma cays
of the Bahamas (DASETT, 1990).
The hydrological structure of Shark Bay, altered by
the Faure Sill, and a high evaporation rate has produced a basin which
is one of the few areas in the world where marine waters are hypersaline,
with salinities almost twice that of normal seawater. Shark Bay is one
in the few marine areas of the world dominated by carbonates. The outstanding
feature of the bay is the steep gradient in salinities which have created
three biotic zones that have a marked effect on the distribution and abundance
of marine organisms. With significant ongoing geological and biological
processes in the marine environment, the steep saline gradients have produced
genetic divergence within local populations, and so is an important area
for genetic biodiversity such as the hypersaline conditions in Hamelin
Pool leading to the development of unique microbialites and microbial
mats.
Shark Bay contains the largest reported seagrass meadows
in the world (4,000 sq. km) as well as some of the most species-rich seagrass
assemblages in the world. As such, thesemeadows are of international importance
for their rich biodiversity and high organic productivity, supporting
a benthic fauna of exceptional abundance. The Wooramel seagrass bank is
the largest reported structure of its kind in the World, covering some
1,030 sq. km. The bank is one of the largest bodies of carbonate sediment
formed by an organic baffle (stabilised carbonate sediment bound by seagrass
beds) yet recorded from a modern environment. The only deposits of comparable
origin and size are the seagrass beds on the Mediterranean coast of France
(DASETT, 1990; Collins, in litt., 1990).
Shark bay is of great botanical and zoological importance
as the habitat of many species at the limit of their geographical range.
It is the habitat for many species of plants and animals that are recorded
as nationally and globally rare, vulnerable or threatened. Fifteen species
of plant are considered to be rare or threatened at the national level.
There are 26 globally threatened mammal species in Australia, Shark Bay
has the only or major populations of five of these. Shark Bay contains
approximately 12.5% of the world population of dugong (Marsh, H., pers.
comm., 1991), is a significant staging post for humpback whales and provides
notable nesting sites for two species of endangered marine turtle. The
only known 'lek' mating system in any marine mammal in the world is observable
amongst South Cove dugong. The phenomenon of wild dolphins voluntary approaching
humans is extremely uncommon worldwide; the only other similar long term
interactions of wild dolphin and man are at Banc d'Arguin in Mauritania
and another more recently established site in Brazil.
CONSERVATION MANAGEMENT The responsible administrative
body is the Department of the Arts, Sports, the Environment, Tourism and
Territories (DASETT), with its headquarters in Canberra. An agreement
exists between the Government of Australia and the State of Western Australia
on legislative and administrative arrangements for the management of Shark
Bay. Collaborative bodies include the Department of Conservation and Land
Management of the state of Western Australia. Day to day administration
is undertaken by Western Australia primarily by the Department of Conservation
and Land Management. It is in accordance with existing Western Australian
legislation, including the Fisheries Act, Local Government Act, Land Act,
Conservation and Land Management Act and the Environmental Protection
Act.
In 1986 the Government of Western Australia resolved
to prepare a planning strategy for Shark Bay, the Shark Bay Region
Plan which is reported to simply favour the maintenance of the economic
status quo (Humphries, 1990). It was released for public comment
in 1987 and finally adopted by the Western Australian government in June
1988. The Shark Bay Region Plan is currently being reviewed by the Western
Australian Government. More detailed management plans are currently being
prepared for all conservation reserves in the area. Draft management plans
for the Shark Bay Marine Reserves, and the Monkey Mia Reserve were released
in 1994 and 1993 respectively. A draft plan for the management of fish
resources in the World Heritage Area was released in 1995. A strategic
plan for the Shark Bay World Heritage Property is also in preparation
(DCLM in litt. 8 February 1996). Any future, major changes to land-use
would require further public consultation and Western Australian parliamentary
approval (DASETT, 1990). The region plan listed a total of 200,000ha in
existing protected areas in 1988. It identified further a proposed protected
areas extension to 755,000ha or 35% of Shark Bay. There are no aboriginal
reserves in the Shark Bay area.
The Sustainable Future for Shark Bay report
shows that environmental protection and appropriate local economic development
can be integrated into the area's management. It contains a broad management
plan which if adopted, will enable conservation values to co-exist with
fishing, tourism and the existing salt works. The disruption to the region's
pastoral industry, it is reported, would be minimal (Humphries, 1990).
Offshore islands, including Bernier and Dorre islands are also nature
reserves managed for conservation. The island reserves are recognised
by restrictions on public access. The management of the trawl fishery
includes restricting the number of boats, minimum mesh sizes, specifications
and size of the fishing gear, setting up closed seasons and protection
of the Shark Bay nursery areas (WAFIC, 1991). Damaging use of gill nets,
which became serious in 1980-81, was effectively curbed by regulations
introduced in 1981-82 (Anderson, n.d.). The Western Australian Department
of Fisheries has assessed commercial fishing pressure and undertaken extensive
aerial survey programmes and identified that commercial fishing in and
around Shark Bay is relatively light (Anderson, n.d.). Insufficient information
is available as to whether World Heritage nomination will lead to further
restrictions of the local fishery as has been claimed by some sources
(WAFIC, 1991).
In June 1990, the 105,352ha Peron pastoral lease was
purchased by the Government of Western Australia primarily for the purposes
of conservation as outlined in the region plan. The northern part of the
lease was gazetted as the Francois Peron National Park in 1993.
A feral animal control programme is ongoing, and consideration
is being given to extend control measures to prevent increases in populations.
Successful control programmes have been undertaken already, such as the
eradication of goats from Bernier island.
In 1986 five full-time rangers were appointed to Monkey
Mia dolphin area to prevent interference with dolphins and to undertake
public awareness programmes as a consequence of increased human pressure
(Edwards, 1986).
MANAGEMENT CONSTRAINTS The whole terrestrial
section of the Shark Bay area has been partially modified due to the impact
of pastoralism and other human activities. The pastoral leases exhibit
localised areas of high disturbance around homesteads and stock watering
points. A number of areas show evidence of past overgrazing by stock leading
to soil and erosion. The most disturbed areas were in the Tamala and Peron
stations, where grazing and feral animals, particularly introduced rabbits
and goats as well as predators such as fox and domestic cat, adversely
affected the abundance of native animals, fire regimes have changed and
grazing pressure is severe (DASETT, 1990). Peron station has since been
purchased by the Government, grazing terminated, major feral animal control
programme implemented, and the northern part of the station has been gazetted
as a National Park (DCLM in litt. 8 February 1996).
The marine environment has undergone some modification
as a result of the pearl shell industry, whaling and heavy fishing, the
latter of which continues using bottom trawling, nets, lines and cray
pots. In May 1990, a Greenpeace spokesman called for a ban on Shark Bay
trawling and in July 1990 the executive director of the Australian Conservation
Foundation is reported to have written to the Commonwealth Minister for
the Environment stating that he had significant reservations about techniques
used by the fishery; as a consequence fishermen are opposed to World Heritage
listing. The fishing industry in thearea totally refutes these allegations
and states that fishermen harvest these resources at a sustainable level
(WAFIC, 1991).
The township of Denham and the areas around Useless
Loop and Useless Inlet are excluded from the nominated area although situated
in the centre of the zone. They could cause adverse impacts on the environment
of the nominated area in the future. In particular, the Useless Loop evaporation
salt works and the gypsum mine on Edel Land have been listed as potential
threats (Anderson, n.d.; DASETT, 1990). Tourism, such as boat activity
along the inner coast of Dirk Hartog Island, may also pose a threat. There
are risks of dugong, dolphin and marine turtle casualties from recreational
boating. This is a much greater threat than the less than a dozen presumed
dugong killed annually by local inhabitants of the region, for food. Insufficient
staff has long been regarded as a hindrance. For long only one fisheries
officer was available to patrol the entire region and proved entirely
inadequate to prevent poaching (Anderson, n.d.).
Insufficient management controls have led to tourist
pressure on the habituated population of wild dolphins at Monkey Mia.
Tourism is still on the increase, resulting in the appointment of full-time
rangers. In 1989 a dead calf and a further six dolphins were presumed
to have been killed by pollution from a septic tank which has since been
removed (Fox, 1991). The construction of a new road to Denham/Monkey Mia
and the building of motels, hotels and caravan parks is dramatically increasing
visitor numbers and seriously affecting the area (Fox, 1991). A draft
management plan for Monkey Mia was released in 1993. (DCLM in litt. 8
February 1996).
