Return
to 1616: Dirk Hartog Island National Park ecological restoration project
February
2013. A ground-breaking and world-class project is set to restore ecosystem
health and wildlife diversity to Western Australia's biggest island, Dirk
Hartog Island, situated in the Shark Bay World Heritage area on the far western
edge of the Australian continent.
13
ground dwelling mammals disappeared from the island
The Return to 1616 project aims to return the 63,000 hectare island to its
pristine state of 400 years ago, when Europeans first landed there. In 1616 at
least 13 ground-dwelling native mammal species occurred on the island. These
included small kangaroo-like boodies and woylies, and western barred
bandicoots, chuditch and dibblers.
Removal
of sheep and goats
The ambitious program will see the removal of all sheep, goats and feral cats
from Dirk Hartog Island, re-establishment of healthy vegetation and
re-introduction of mammal species once known to exist there.
The
project is funded by DEC and the Gorgon Barrow Island Net Conservation Benefits
fund in a partnership that has the potential to yield world-class conservation
outcomes over the next 20 or more years.
Chuditch
and dibblers
In 1616 the island was pristine, with at least 13 ground-dwelling native mammal
species. These included small kangaroo-like boodies and woylies, and western
barred bandicoots, chuditch and dibblers. From the 1860s until the early 2000s,
the island was used by pastoralists to run sheep, and the Cape Inscription
lighthouse was established in 1910. By the late 20th century the island had
become popular with fishing enthusiasts, divers and snorkellers.
All
but 3 mammals disappeared
By this time goats and feral cats were well established on the island and only
three small mouse-sized native mammal species still occurred; the ash-grey
mouse, sandy inland mouse and little long-tailed dunnart. In 2009 Dirk Hartog
Island became a national park, providing the Department of Environment and
Conservation (DEC) with the opportunity to restore its natural environment in
partnership with the island's other land managers and the Shark Bay community
