The botanical imperialism of weeds and crops: how alien plant species on the First Fleet changed Australia

Locally grown produce fills Australian shops, but almost all of these species were imported, as native as cane toads. Icons of Australian agriculture, like the Big Banana and Big Pineapple, proudly display the regions’ crops, but these are newcomers to the continent.

British ships carrying plants and seeds from around the world arrived in Botany Bay on January 20 1788. This story is overshadowed by convict ships and Royal Navy vessels, but the cargo on board also had a lasting impact. Colonists, convicts and Indigenous Australians were all affected when new species transformed the landscape.



British colonists introduced plants as foreign as the people who carried them. Some of these plants, ranging from bananas to wheat, were food sources, promoting self-sufficiency. Others were attempts to expand the British Empire. Could the new territory be exploited as a tropical plantation?

Botanical imperialism​


In the parliamentary debate over destinations for convict transportation, Sir Joseph Banks and James Matra, both members of James Cook’s 1770 expedition, spruiked the potential of the new colony as an extension of the empire.

Matra claimed the colony was “fitted for production” of “sugar-cane, tea, coffee, silk, cotton, indigo and tobacco”.

Banks claimed Botany Bay was an “advantageous” site, with fertile soil – and virtually no inhabitants.

Two plants carried by the First Fleet stand out as examples of botanical imperialism: prickly pear cactus (Opuntia) and sugarcane. Banks, as head of the Royal Society of London, selected these species as experiments to compete with European trade rivals.



His goal was to break a Spanish monopoly in producing fabric dye and to expand British cultivation of sugar outside the West Indies.

The secret of the colour scarlet​


Prickly pear cactus was imported because it is the preferred food of the cochineal insect. Dried cochineal were crushed to make a vibrant, colourfast scarlet dye for textiles. Discovered in the New World by Spanish colonists, cochineal replaced kermes, another insect that had provided red dye since antiquity.

Cochineal dye was ten times stronger than kermes or vegetable dyes. From cardinals’ capes to British officers’ red coats, cochineal was a product for elite consumers signifying power, wealth and prestige.

New Spain, based in Mexico, had a monopoly on cochineal. Banks wanted to break the stranglehold on the scarlet dye by establishing production in New South Wales. Plants infested with the precious insects were imported from Brazil in 1788.

The project soon failed when the cochineal died, but the cacti survived. Colonists used cacti as natural fences and drought-resistant animal fodder. Without insects to feed on them the plants spread, uncontrolled, to cover more than 60 million acres of eastern Australia by the 1920s. Poison, crushing and fire failed to stop the cactus.

In 1926, a moth species from Argentina was introduced to eradicate the plants, but Opuntia cacti remain an environmental hazard. Trade in the plants, classified as weeds of national significance, is banned in most states.



The first sugar grown in Australia​


Sugarcane was imported from the Cape Colony, now South Africa. Before sugar was planted in Queensland, or even Port Macquarie, in the 19th century, sugar was grown in a small garden plot in Sydney and as an experimental crop on Norfolk Island in 1788.

The Royal Navy targeted Norfolk Island as a source of flax and timber, but it also served as an agricultural laboratory, testing tropical crops like sugar and coffee for Banks.

Philip Gidley King, lieutenant-governor of Norfolk Island, reported in his correspondence with Banks in 1790 that his four canes had multiplied into more than 100 plants. Within a few years he sent samples of sugar, rum and molasses to Sydney. By 1798, the cane was declared “prolific” and Norfolk Island was in “a state of cultivation equal to the West Indies”.

This favourable comparison with the West Indies ignores the use of convict labour in producing sugar, and foreshadows the advent of “blackbirding”, a euphemism for the abduction or coercion of Melanesian workers. Blackbirding was introduced in Queensland canefields in 1863 as penal transportation ended and cheap convict labour became unavailable.

Once essential to the sugar industry, in 1901 Pacific Islanders in Australia were deemed undesirable, competing unfairly with white workers. As part of the White Australia Policy, many were deported under the Pacific Island Labourers Act 1901.



The fruits of empire​


Reconsidering the impact of alien plant species on Australia gives us additional insight into the process of colonisation.

Transplanting species from around the world to create a new environment was a major endeavour in the 18th century, and a manifestation of imperial power and control.

Indigenous connections with Country were disrupted when foreign botanical landscapes displaced native species. The roots of these early imperial projects are deeply embedded in Australian culture and history, with an enduring legacy.

Yes it's true that these came from overseas 4 centuries ago. Don't forget though that before our people came the Dutch explorers, and you can be very sure that they would have had many pests and weed-like plants with them as well, plus passing on their illnesses to the Indigenous people. I'm not Indigenous, and wonder why that when our First Nations people refer to Australia as 'Country', do they mean it's their Country alone? If so, I take exception to this. They have been her for many many years but remember, their Culture too did not originate here, they too long ago were probably the first Immigrants to our great Land the Country of Australia.

Many a true word, so this means that the 'First Nations' people are also not truly indigenous so why is that reference used I wonder.
