Not being
from Australia I was somewhat surprised when I had learned just a couple weeks
ago that there were Camels in Australia. Granted I had never really given much
thought to this particular idea but at the same time Australia, even in the
outback, is not exactly where I expect to find Camels. I was even more intrigued when a
conversation was brought up about the Camels in Australia and how there is a
rumour of ongoing studies showing that this introduced species may also be
serving a potential benefit benefit which intrigued me even more. Therefore, I
thought it only made sense to research this topic some more.
The camels
were introduced into Australia in the 1800’s. They were brought in to assist in the discovery and
exploration of Australian land as they were more efficient and cost effective
compared to what a horse, mule, or ox was capable of (Big Black Dog
Communications Pty Ltd 2009).
The negative
impacts of introducing the camel, like many introduced species were unknown at
the time of introduction. With the
current estimated population size of about one million camels in Australia the
impacts include environmental, social and economic issues (Government of South
Australia 2013). According to the
Government of South Australia, that population size is expected to double
within the next 10 years (2013).
Through just
browsing the internet I found multiple sites advertising camel rides and
safaris provided throughout Australia for the most part. Being that there is a market for this
tourism attraction one potential benefit is from an economic perspective. There are currently at least one
hundred camel farms throughout Australia providing multiple purposes (Paroz
2008). Services provided by the
farms are camels for export, meat, tourism and weed control (Paroz 2008). Therefore, I was able to find some
information tying camels to an environmental benefit of grazing upon areas
which contain woody, prickly weeds that are not generally consumed by other
animals. While camels will eat a
variety of vegetation such as these woody weeds, camels are found to be
ineffective when it comes to consuming these weeds when they are mixed with
thick vegetation (Paroz 2008).
Camels,
while an introduced species, appear to provide some slight benefits such as
weed control but at the same time they also contain the negative impacts as
seen by many introduced species.
However, being that such economic gain has come from the camels, it is
highly unlikely to see them disappear any time soon. There are a few methods of control in place for the camels
under the State Feral Camel Management Project per the Government of South
Australia (2013), which is a joint effort exercising various methods of
control. Some methods include
funding for enclosures, and harvesting (Government of South Australia 2013).

Yes, it does seem strange to think of camels in Australia. I think that the potential economic benefits of this species do make it an interesting one for considering how to manage invasive species. Why do you think camels are so successful? I would have thought that, being of larger body size, they would have a longer gestation period. In addition, they are arid-dwelling species (generally) so surely they should be limited in their reproductive capacity by the environment? Good post!
ReplyDeleteI think that because they have the ability to withstand harsh conditions that gives them an advantage. This, in addition to not having their normal competition possibly provides them with a whole new abundance of resources they otherwise would not have.
