What is the primary issue with rabbits introduced to Australia?

The primary issue with rabbits introduced to Australia is that they exemplify the high biotic potential of some introduced species. When rabbits were brought to Australia in the 1800s, they were able to reproduce rapidly due to their high reproductive rates. A single female rabbit can have multiple litters each year, and each litter can contain numerous offspring. This high biotic potential allowed their population to explode in a short period, leading to significant ecological consequences.

The introduction of rabbits disrupted local ecosystems as they outcompeted native species for food and habitat. Their grazing habits also contributed to land degradation, soil erosion, and changes in plant communities, which further harmed native wildlife and biodiversity. This situation highlights how certain species can thrive in new environments when they lack natural predators and how their rapid growth can have detrimental effects on existing ecosystems.
