dirk hartog island Flashcards
what is dirk hartog island
is WA largest island, located in the shark bay world heritage area
what is the program implicated for dirk hartog island
the program aims to restore the island to its condition in 1616 when it was first visited by Dirk Hartog and addresses the impacts of land cover change
what does land cover change on the island include
deforestation, expansion and intensification of agriculture, and the introduction of feral cats, sheep, and goats
what does the program include
the program includes ecological restoration, weed management and vegetation and habitat recovery, and it started in 2007 with the destocking of sheep and goats
the program also includes an ongoing weed management program with five weeds listed for eradication measures
how many sheep and goats had been removed from the island since 2017
by the end of 2017 over 5000 sheep and 11,000 goats had been removed from the island, and feral cats were eradicated by trapping and tracking
what did removing these species cause
the removal of these species resulted in a 35% increase in vegetation cover, and negative species, such as the banded and rufous hair wallabies were reintroduced to the island
was the program successful
the program has been successful in preventing exposure to five weeds found in shark bay mitigating future land cover change
how much did the program cost
16.7 million overall
the cost of the program was around $150 per goat, and it is considered a world-leading ecological restoration program that may assist in mitigating future land cover change in other environments
is the island a national park
yes, the establishment of the island as a national park in 2009 provided more stringent protection measures
what does the return of the 1616 strategy focus on
the return to the 1616 strategy focuses on community engagement
who provides upates on dirk hartog island
the Wirruwana news provides updates on Dirk hartog island national park twice a year
what did the island do to engage community
the island developed an interactive web-based education package for primary school students with a focus on conservation
the shark bay Arts council shed created a community art project that aligned with the return to 1616 strategy in 2016
the program involved community members and staff/prisoners at Albany regional prison building boxes to transport feral species to the island

what did the heritage agreement get made
a heritage agreement was created in negotiation with the Yamati Marla Aboriginal Corporation to ensure that Aboriginal heritage values were not affected by the proposed works
an additional agreement was formed with the Wardle family, allowing the expansion of tourism on the island
what did the island get as an extension of the native title
in 2018, over 28,000 square km of land and water in the shark bay area was granted as an extension of the native title
what did the island achieve
the island achieved advanced ecotourism certification and runs 92% of the island’s power by a hybrid solar and wind powered generator
what is the accommodation on the island supplied by
is supplied by a solar pump and windmill in addition to a desalination system
what does the ecolodge do
the ecolodge has a glass crusher and recycles cans and tins
what was dirk hartog island used for
dirk hartog island was used as a pasture for sheep and goats from the 1860s to 2009, with many feral goats and sheep released on the island
what funds were given to the island
a caring for our country grant from the commonwealth government and funding from the Gorgon Barrow island Net conservation benefit fund were used to remove the feral species on the island between 2010-2013
how much were the funds for the island
the removal of feral cats on the island began in 2011 with funding of over $8.5 million from the Gorgon Barrow Island Net conservation benefits fund and an additional 4.8 million from the department of environment and conservation for the first stage
how much is it to remove feral cats over 7 years
the program to remove feral cats is expected to cost an estimated $16.7 million, over 7 years, with on going maintenance and monitoring required until 2030
what does the feral cat program involve
the program involves highly trained dogs to hunt feral cats, with a zoologist mapping grids to follow and identifying if new baits or traps are needed
who was employed for the feral cat program
a project manager, two project officers, and a local Aboriginal trainee were employed to manage the program, with steering and management committees established
what does the return to the 1616 strategy involve
the return to 1616 strategy involves community engagement through education programs, community arts projects, and even an eco-tourism distinction
what can be said about the return to 1616
the return to 1616 strategy is a large ecological restoration project in the southern hemisphere
what was reintroduced to dirk hartog island
36 dibblers were reintroduced to dirk hartog island in 2019, with some bred at Perth zoo as part of their native species breeding program
what innovative strategies were implemented
including creating artificial burrows for the mice to be released into pseudo dunes, which they eventually transitioned out of and built their own burrows
what was dirk hartog island home to before and after introduced species
dirk hartog island was home to 13 native mammal species, with only three remaining after the introduction of sheep, goats, and cats
when did the island become a national park
most of the island became a national park in 2009 while still allowing recreational use
why did the program operate in stages
the program operated in stages, with the eradicationnof introduced species being essential for the protection of reintroduced native species
what was the eradication of goats, sheep and cats
the eradication of goats and sheep had an estimated likelihood of eradication at a rate of 96.9% and 99.99% respectively
the eradication of cats showed a 93% reduction between May 2014 and may 2015
describe the environmental success on the island
aerial photographs and satellite imagery showed a 35% increase in vegetation cover after the removal of sheep and goats
the program re-established ten native species to the island, including threatened mammals and two additional species that may have inhabited the island
what makes dirk hartog island so important
the success of maintaining these species would make Dirk Hartog island the most diverse of any island in WA, enhancing its characteristics as a world heritage property

- Employment opportunities
- Education in the primary school aged students in conservation
- The provision of opportunities for prisoners to become involved.
- Expansion of tourism
- Involvement of first nations peoples- custodianship of the land
Community involvement through arts projects

- Two project officers, project manager, trainee
- Costs-being met by federal government 2010-2013
Chevron key contribution+ state agencies
positives of the environmental aspects of the 1616 program
- 36 Dibblers have been reintroduced from Perth zoo
- 96.9% of goats have been removed
- 99.99% of sheep have been removed
- by 2018 no feral cats detected for two years
- Removal of sheep and goats= 35% increase in vegetation
10 native species returned to the island+ 2 addition species e.g rufous and banded hare wallabies
what did DR sims say
Dr Sims, senior officer on the Dirk Hartog Island Ecological Restoration Project, lights up when talking about the work she has been doing for years.
“We are trying to return the island back, as near as possible, to what we think it was like before Europeans first set eyes on it,” she says.
describe how mulgara’s are being introduced and where from
The mulgara’s are from more than 800 kilometres away at Matuwa Kurrara Kurrara National Park, where the marsupials are being collected with permission and assistance from the area’s Martu traditional owners.
The national park, north of Wiluna in WA’s Goldfields, has one of the healthiest populations of the surviving mulgaras, which are close to being listed as a vulnerable species.
In total, 100 mulgaras will be flown to the island.
describe what aline is doing for her PhD
And a few weeks ago, 85 Western Grasswrens were successfully translocated to the island from and Francois Peron National Park and Bush Heritage’s Hamelin Station Reserve on Malgana and Nanda Country, bordering the Shark Bay World Heritage Area.
The translocation was informed by researcher Aline Gibson Vega’s PhD project and is part of a collaboration between DBCA, Bush Heritage Australia and the University of Western Australia.
what does aline say
It’s just great to see that we’re going to have this little insurance population essentially.”
