Feral camels are well adapted to the conditions found in desert
Australia and have now occupied 3.3 million km2. They
are one of the 73 or so species of introduced vertebrates occurring
on mainland Australia that do not meet the criteria to justify
eradication effort. For such species, the management options are
containment, control, or no management (Australian Pest Animal
Strategy 2007).
Because they occur in sparsely populated areas, feral camels are
only noticed when their activities intersect with remote Aboriginal
people, pastoralists, and the tourism and mining industries. The
significant damage that camels have done, and are currently doing,
to the fragile ecosystems, cultural sites, isolated communities,
and pastoral enterprises of desert Australia has gone largely
unnoticed by the bulk of Australia’s population. The current
estimated population of about one million feral camels is doubling
approximately every nine years (Saalfeld & Edwards 2008) and
there is evidence that impacts will increase along with the
population (Edwards et al. 2008). If we do not act now to mitigate
the damage being caused by feral camels, irreparable damage may be
done, particularly to environmental and cultural values, across
much of desert Australia. The longer we take to act, the more it
will cost to manage and repair the negative impacts of feral
camels.
Management of the impacts of pest animals should be informed by
a risk management approach and be strategic in determining where
management should occur, at what time, and what techniques should
be used (Australian Pest Animal Strategy 2007). It
requires coordination at the appropriate scale among all levels of
government in partnership with industry, land managers, and the
community (Australian Pest Animal Strategy 2007). The
current management of feral camels, being largely ad hoc (Edwards
et al. 2004), fails to adequately meet any of these criteria.
If we are to develop a strategic, coordinated risk management
approach to mitigating the impacts of feral camels, it must be done
at the national scale because:
- There is a large population of camels occurring over a large
area which includes parts of Western Australia (WA), South
Australia (SA), Queensland (Qld), and the Northern Territory (NT)
(Saalfeld & Edwards 2008).
- Camels are very mobile animals that can move over large
distances in relatively short time periods (Saalfeld & Edwards
2008).
- Many camels occur in very remote areas that are sparsely
populated by people (Saalfeld & Edwards 2008, Saalfeld et al.
2008).
- There are differing perceptions on feral camels and their
impacts (Zeng & Edwards 2008a, 2008b; Vaarzon-Morel
2008a).
- Camels are considered both a pest and a resource (Edwards et
al. 2008), which can lead to conflicting goals between the various
stakeholders in respect of their management.
The research described in this report was funded by the
Australian Government. It was conducted with the overarching aim of
developing a national management framework which will lead to a
reduction in camel numbers to a level that reverses their current
population growth trajectory and reduces their impacts on natural
resource management (NRM), economic, and social-cultural
values.
The key outputs of the research were:
- Detailed analysis of management system options that lead to a
significant lowering of camel numbers and resulting improvement in
economic, environmental, and social/cultural values
- Improved understanding and documentation of the cultural and
other barriers to different feral camel management options
- An analysis and documentation of the role of at least two
alternative market-driven approaches to camel control that can help
to mitigate the negative impacts of the species
- Development of a framework for the cross-jurisdictional
management of the negative impacts of feral camels.
The overarching aim of developing a management framework for
addressing the negative impacts of feral camels was achieved
through a group of well-integrated sub-projects, based on a
collaboration between different stakeholder groups, in a range of
jurisdictions, working on a series of related projects across the
country. The research was undertaken through five core
sub-projects:
- Evaluation of key stakeholder perceptions: This work focused on
Aboriginal, conservation, and pastoral land owners and managers
within the camel’s range.
- Evaluation of the impacts of feral camels: This work adopted a
triple bottom line approach in considering economic, environmental,
and social (including cultural) criteria.
- Evaluation of commercial approaches that could assist in
managing the negative impacts of feral camels: This work considered
aspects such as the live export of camels and the use of camels for
pet meat and for human consumption.
- Evaluation of the non-commercial approaches that are or could
be used in the management of the negative impacts of feral camels:
This work considered aspects such as aerial culling, ground
culling, and fencing. A review of possible chemical, biological,
and fertility control options for managing the negative impacts of
feral camels was also conducted by a research team based at the
Invasive Animals Cooperative Research Centre.
- Development of a framework for the cross-jurisdictional
management of the negative impacts of feral camels. In developing
the framework, the following tasks were undertaken:
-
- The compilation of spatial data relevant to the management of
feral camels and their impacts
- The development of a Multiple Criteria Decision Support Tool
for Feral Camel Management based on a Geographic Information System
(GIS).
The following additional work was undertaken for the
project:
- A review of legislation to identify possible barriers to the
cross-jurisdictional management of feral camels and their impacts.
A team based at Charles Darwin University and led by Stephen
Garnett undertook this research.
- Modelling of options for management of feral camels in central
Australia: Stephen McLeod, from New South Wales Department of
Primary Industries, and Anthony Pople, from Queensland Department
of Primary Industries and Fisheries, undertook this work.
- An economic analysis of camel control in the central region of
the NT: Adam Drucker, from Charles Darwin University, undertook
this work.
The following discussion summarises the research outputs of all
work undertaken for the project and provides key recommendations
for the effective cross-jurisdictional management of feral camels
and their impacts. Preceding chapters of the final report contain a
much higher level of detail in relation to the work undertaken and
may include additional recommendations pertaining to individual
research components.
