Section A Western Port
  • Western Port is a large coastal bay in Victoria.
    It is located roughly 60 km south east of
    Melbourne. It contains two large islands Phillip
    Island and French Island and many other small
    islands.
  • Over the years there have been many industrial
    developments in Western Port, the local
    population has also grown considerably along with
    recreational activities in the area. These
    developments have induced many negative
    environmental changes including altered water
    regimes, pollution, and increased levels of
    sediments and nutrients.

Section A Western Port
  • Western Port is a very important ecological area
    because it supports a wide range of terrestrial
    and marine animal and plant species. Western Port
    is listed as a Ramsar site, which means that it
    contains wetlands of international importance.
  • WWF Australia has been working in 5 shorebird
    sites across Australia (including Western Port).
    These sites have been identified as nationally
    and internationally important for shorebirds.

Section B Shorebirds
  • Shorebirds are a group of birds that are found
    wading in shallow water looking for food on
    coastal mudflats, estuaries and along the edges
    of inland wetlands.
  • There are 3 categories of shorebirds local,
    migratory and vagrant.
  • The habitat of most migratory and local
    Australian shorebirds is a variety of wetlands.
  • Shorebirds eat small worms, insects, fish and a
    variety of molluscs and crustaceans.

Section B Shorebirds
  • Shorebirds feed via probe or surface feeding
    methods.
  • The legs and bills of different types of
    shorebirds are suited to the way in which they
    get their food.
  • Migratory shorebirds are well adapted to flying
    long distances.

Section B Shorebirds
  • Most migratory shorebirds breed in northern
    China, Mongolia, Siberia and Alaska, during June
    and July.
  • Most shorebirds use the East Asian-Australasian
    Flyway to come to Australia during the
    non-breeding season, where they stay from August
    to April.

Section C Western Port Wetlands
  • Wetlands are areas that are covered with water on
    a temporary or permanent basis. The water is
    usually slow moving or stationary, shallow,
    fresh, brackish or saline.
  • There are many different types of wetland.
  • Western Port is listed as a Ramsar site which
    means that it contains wetlands of international
    importance.
  • In the past, wetlands were sometimes thought of
    as wasteland.

11
Section C Western Port Wetlands
  • Now, it is understood that wetlands are
    environmentally, socially and economically
    important, and therefore, must be protected.
  • Wetlands are an important shorebird habitat. They
    provide food and shelter and are useful during
    migration.
  • The bad news is that wetlands at Western Port and
    around the world are being damaged as a result of
    human activities.
  • The good news is that there are many conservation
    projects currently underway to help protect
    wetlands.

Section D Conservation Status of Western Port
Shorebirds
  • A number of migratory and local Western Port
    shorebirds are currently listed as threatened at
    some level. However, some species have increased
    in number, so it is not all bad news.
  • Threats to shorebirds at Western Port include
    human disturbance, water pollution and introduced
    plants and animals.
  • Threats to migratory shorebirds during their
    northward migration include habitat degradation
    and loss, pest animals and plants, hunting and
    climate change.

14
Section D Conservation Status of Western Port
Shorebirds
  • There are a number of international, national and
    local conservation efforts currently underway to
    protect Western Port shorebirds and their wetland
    habitat.
  • Examples of successful conservation efforts
    undertaken at Western Port are the Phillip
    Island Hooded Plover Watch and Stockyard Point
    Shorebird Conservation Project.
  • There are a number of practical ways that your
    students can help conserve Western Port
    shorebirds.
