Invasive species in Australia
Wikipedia W icon.svg

An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become a serious economic, social, and environmental threat worldwide.

Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with international trade. Notably invasive plant species include the kudzu vine, giant hogweed, Japanese knotweed, and yellow starthistle. Similarly invasive animals include European rabbits, domestic cats, and carp.

Invasive herbs[edit | edit source]

Invasive herbs refers to herbs that have a tendency to take over your garden or growing space. Although such herbs are usually grown for their herbal benefit (culinary, medicinal, appearance, etc.), the ability of such herbs to take over the garden can be a real problem and might even put the herb gardener off growing them again. These herbs need to be managed to prevent their spread, meaning that they can still be enjoyed as part of a garden without taking it over. And you might be surprised that the tenacious invasive herb survives when other plants keel over in the heat or cold extremes, so sometimes it is a blessing to have a little something still growing in the garden when all else fails!
