Australian feral camels are Dromedary camels (Camelus dromedarius) that were imported from British India and Afghanistan during the 19th century for transport and construction during the colonisation of Australia. They are descendants of domesticated camels that were released into the wild by early European settlers. Camels are highly mobile and can travel up to 70km a day in search of food and water, making them highly adaptable survivors of the Australian Outback. They are not picky eaters and will eat almost any available plant, including grasses, fruit, leaves, and stems of many shrubs.

Camels eat grasses, fruits, leaves, and stems
Australian feral camels are the descendants of domesticated camels that were released into the wild by early European settlers. They are Dromedary camels (Camelus dromedarius) and were first introduced to the country from the Canary Islands in 1840. Today, there are approximately 1.2 million feral camels in Australia, with most of them found in Western Australia.
Camels are highly adaptable survivors of the Australian Outback and are not picky eaters. They eat almost any available plant, including grasses, fruits, leaves, and stems of many shrubs and trees. Camels feed for 6-8 hours a day and then spend another 6-8 hours ruminating or chewing the cud. Their long necks enable them to browse trees much further from the ground than any other terrestrial herbivore in Australia.
Grasses make up a significant portion of a camel's diet, ranging from 20-40%. They also consume the fruits, leaves, and stems of various shrubs and trees, such as the Quandong or Native Peach (Santalum acuminatum). Camels have a preference for succulent herbage that is high in water and often salt content. This is in line with their ability to survive long periods without water, which they achieve by reducing sweating, concentrating their urine, and extracting water from fat stored in their hump.
The impact of feral camels on the environment is a concern. They can cause serious degradation of local environmental and cultural sites, particularly during dry conditions. Camels compete with endemic animals, such as kangaroos and other marsupials, for food and water. Their feeding habits also affect important food plants used by Aboriginal people and fragile salt lake ecosystems.

They feed on over 80% of available plants in Central Australia
Australian feral camels are not picky eaters. They feed on over 80% of the available plants in Central Australia. Their diet includes grasses, fruit, leaves, and stems of many shrubs. They also eat native trees such as the Quandong or Native Peach, and other plants used by Aboriginal people.
Camels are highly adaptable survivors of the Australian Outback. They can travel up to 70 km a day in search of food and water. They are also able to survive for a week without water, relying on fat reserves stored in their hump. This ability to go long periods without water has made them well-suited for the Australian desert.
The camels' long necks enable them to browse trees much further from the ground than any other terrestrial herbivore in Australia. They spend 6-8 hours feeding and another 6-8 hours ruminating (chewing the cud). They are also known to cause serious degradation of local environmental and cultural sites, particularly during dry conditions.
Feral camels directly compete with endemic animals, such as kangaroos and other marsupials, for food and water sources. They may have an advantage over other mammals as they can digest many plant species that are unpalatable to other animals. This allows them to thrive in environments where other species may struggle.
The impact of feral camels on the environment and native wildlife has led to concerns about their rapidly growing population. Management and culling methods have been implemented, but their effectiveness in controlling camel populations is limited. The introduction of camels to Australia and their subsequent release into the wild has resulted in significant ecological challenges that continue to be addressed.

Camels are known to damage native trees like the Quandong
Camels are known to have a detrimental impact on native trees and vegetation in Australia. The Quandong tree, also known as the native peach, is one such tree that camels are known to damage. The Quandong is a shrub or small tree, reaching up to 4 meters in height, with rough dark bark and light green, slightly leathery leaves. It is native to arid and semi-arid regions of Australia, particularly the southwestern third of Central Australia, where it grows in small groups near waterways, salt lakes, or hills.
The Quandong is considered highly palatable to camels and is vulnerable to their browsing habits. Camels may have contributed to the decline in Quandong populations, and the species is now listed as threatened in the Northern Territory. The tree has also been impacted by the destruction of indigenous culture and traditions, as it is known to be a traditional staple food for central Australian Indigenous people for tens of thousands of years.
Camels compete with endemic animals, such as kangaroos and other marsupials, for food and water sources. They consume a large portion of the available plant matter, including the Quandong, and can survive in arid conditions by utilizing the fat reserves stored in their hump. This competition for resources has a detrimental impact on the environment and the cultural values of Aboriginal people.
In addition to feeding on the Quandong, camels also damage the tree through their trampling behavior. This can lead to the suppression of recruitment in some plant species and the destruction of bush food resources, further impacting the Indigenous communities that rely on these trees for food and cultural practices. The Quandong tree is also fire intolerant, and the Indigenous practice of "firestick farming" has traditionally helped protect the species from the threat of wildfires.
Overall, the presence of feral camels in Australia has had a significant negative impact on the Quandong tree and other native vegetation. Their feeding and trampling behaviors, combined with their ability to thrive in arid conditions, have contributed to the decline of the Quandong and other native plant species.

They can survive a week without water, but drink up to 145 litres in one go
Camels are well-known for their ability to survive without water for extended periods. This remarkable adaptation allows them to endure the harsh conditions of the Australian Outback, where they can go for a week without accessing water sources.
Camels have evolved various mechanisms to conserve water. For instance, they reduce sweating and concentrate their urine, similar to other desert mammals. Their body temperature can rise by nearly 3°C before they start to sweat, and they can tolerate significant fluctuations in body temperature, with a drop of up to 6°C at night. This ability to regulate body temperature helps them retain water in the hot and arid environment.
The hump of a camel is an essential reservoir, storing fat and connective tissue that can provide energy and water when resources are scarce. This stored fat enables camels to survive and maintain their activity levels even when water is unavailable. The hump's shape and size are indicative of the camel's overall health and condition.
Despite their remarkable water-conserving abilities, camels will consume large amounts of water when it is available. A camel can drink up to 145 litres of water in a single drinking session. This behaviour ensures they can replenish their body's water supply and prepare for potential future shortages.
The ability to survive without water for a week and then rapidly rehydrate by drinking large volumes in one go gives camels a significant advantage in the arid Australian environment. This adaptation, along with their non-selective diet and long-distance foraging abilities, has contributed to the successful establishment and proliferation of feral camel populations in Australia.

Camels are descended from domesticated camels released into the wild
Camels are well-adapted to their desert habitats and have long been valued as a means of transport for passengers and cargo. They are also exploited for milk, meat, wool, and hides. The first camel arrived in Australia in 1840, ordered from the Canary Islands. Over one million dromedary camels are estimated to be feral in Australia, descended from those introduced as a method of transport in the 19th and early 20th centuries. This population is growing at a rate of about 8% per year.
Camels were first domesticated sometime in the 3rd millennium BCE in either Somalia or South Arabia. The process of domestication likely began with the selection of animals that showed less fear of humans. Over time, humans selectively bred these animals for desirable traits, such as tameness. The Bactrian camel, which has two humps, was domesticated by 4000 BCE in Central Asia. Today, there are around 97 domesticated breeds, most of which are in India and the Horn of Africa.
The feral camel population in Australia is descended from pack animals imported in the 19th century. These camels were originally brought to Australia to help with inland exploration and to service the inland pastoral industry. As their knowledge of the Australian outback grew, cameleers began their own businesses, importing and running camel trains. Eventually, some camels were released into the wild, where they thrived and reproduced.
Today, the feral camel population in Australia poses a serious threat to the local environment and cultural sites. Camels compete with native animals, such as kangaroos and other marsupials, for food and water. They are also known to damage fragile salt lake ecosystems and waterholes, which are important sites for Aboriginal people and native plants. The Australian government has culled over 100,000 feral camels to try and control their population growth.
