Rabbits were first introduced to Australia in the 19th century and have since become a pest species, causing damage to the Australian environment and agriculture. They inhabit 70% of Australia's landmass, impacting 75 Commonwealth-listed threatened plant species and five threatened ecological communities. They also affect native vegetation, forestry, and tree plantations, and their burrowing behaviour can undermine roads, culverts, buildings, and sites of cultural significance. Given their status as a pest, rabbits are hunted and harvested for human consumption, though the majority of rabbits sold as meat products in Australia are farmed. In this context, understanding the dietary habits of rabbits is essential for managing their population and reducing their impact on the environment.

What You'll Learn
Rabbits are herbivores
Rabbits are selective feeders, targeting specific plant species at critical stages of their life cycles, such as seeding and seedling establishment. This behaviour severely affects regeneration and can lead to soil erosion. It may also contribute to the dominance of undesirable weed species. Rabbit grazing can result in vegetation loss, impacting dam catchments, water supplies, and topsoil maintenance. Additionally, rabbit burrowing can undermine roads, culverts, buildings, and sites of cultural significance.
Rabbits have a high reproductive capacity, enabling them to quickly recover from adverse conditions such as poor seasons, diseases, and control efforts. Their ability to dig extensive warrens or burrows provides protection from predators and harsh weather, contributing to their successful establishment in Australia. The warrens are essential for breeding, as rabbit kittens cannot survive without shelter.
Rabbits are mostly active from late afternoon to early morning, emerging from their warrens a few hours before sunset. They gradually graze further from their warrens as it gets darker. Rabbits are shy feeders and are cautious of new things in their environment. They have a strong preference for plants with high nutritional value.

They eat crops, roots, and pastures
Rabbits are herbivores and have a varied plant-based diet. They are known to eat crops, roots, and pastures, as well as young trees and vines, and they show a preference for short, succulent plants with high nutritional value. Rabbits can eat up to one-third of their body weight daily, with an average daily intake of 100 to 150 grams. This means that even a small number of rabbits can have a significant impact on vegetation.
Rabbits have a strong preference for certain plant species, especially those with high nutritional value, and will selectively feed on these plants at critical stages of their life cycle, such as seeding and seedling establishment. This behaviour severely affects the regeneration and recruitment of plant species and can lead to soil erosion. It also encourages the dominance of undesirable weed species.
As a result of their dietary preferences and high reproductive capacity, rabbits have become a major pest in Australia, impacting at least 304 threatened fauna and flora species. They are considered the most costly pest vertebrate animal in Australian agriculture, with an annual cost exceeding $200 million. Their grazing habits weaken perennial grasses, potentially eliminating them from established pastures. This then leads to the invasion of broadleaf weeds and annual grasses, making the land less suitable for livestock production.
Rabbits' feeding habits also affect revegetation projects, as they feed on newly planted vegetation. They can cause significant damage to grain crops and have been known to reduce crop yields in certain areas. Their burrowing behaviour further adds to their impact on the environment, as it can undermine roads, culverts, buildings, and sites of cultural significance. Given these factors, it is not surprising that rabbits have been listed as a key threatening process to threatened species conservation under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

They prefer short, succulent plants
Rabbits in Australia are a major pest, impacting 75 Commonwealth-listed threatened plant species and five threatened ecological communities. They are Australia's most costly pest vertebrate animal, costing agriculture over $200 million in lost production every year.
Rabbits are herbivores and will eat a wide variety of plants, including crops, roots, pastures, young trees, and vines. They are selective feeders, preferring short, succulent plants with high nutritional value. They graze very close to the ground, which weakens perennial grasses and can eliminate them from established pastures. This can then lead to the pasture being invaded by broadleaf weeds and annual grasses, making it less suitable for livestock production. Rabbits also affect revegetation projects by feeding on newly planted vegetation. Even a small number of rabbits can have a devastating effect on tree-planting programs or intensive horticultural operations.
Rabbits' preference for short, succulent plants with high nutritional value means they are attracted to crops, which can cause problems for farmers. They also eat young trees and vines, which can impact forestry and tree plantations. Their feeding habits can cause soil erosion and encourage the dominance of noxious or unpalatable weed species.
Rabbits were first introduced to Australia in the late 1800s and quickly spread across the continent. They are now found in a variety of environments, including subalpine areas, stony deserts, subtropical grasslands, and wet coastal plains. Their ability to dig extensive burrows, or warrens, has helped them succeed in Australia, as it protects them from predators and the harsh Australian climate.

Rabbits eat young trees and vines
Rabbits will eat a variety of plants, including many types of young trees and vines. They are known to favour fruit trees, such as crabapples, plums, cherries, and apple trees, as well as other trees like maples, yews, pines, and bald cypress. They will also eat shrubs, including dogwood, viburnum, and ninebark. Rabbits cause damage by stripping the bark off trees and shrubs, which interrupts the flow of nutrients and water, causing girdling. Girdling can be deadly for trees, especially if the bark is removed all the way around the trunk.
Young trees are particularly susceptible to rabbit damage until their bark becomes thick and rough with age. In addition to eating the bark, rabbits will also clip off small branches and buds within their reach. This damage primarily occurs during the fall and winter when other food sources are limited, although rabbits are active all year round. Rabbit damage can be identified by the presence of pea-sized rabbit droppings near the plant and clipping of small, low branches and leaves.
There are several methods to control and prevent rabbit damage to trees and vines. One approach is to use fencing or tree protectors, such as plastic, wire, paper, or tin foil protectors, which can be purchased or made at home. The protectors should be tall enough to cover the tree above the expected snow depth. Another method is habitat alteration, which involves removing brush piles, weed patches, and other dense cover near tree plantings to reduce hiding places for rabbits.
Trapping and hunting are also effective ways to reduce the rabbit population and prevent damage. Trapping is particularly successful in urban areas, while hunting is most effective in the early morning and late evening when rabbits are most active. Repellents and baiting can also be used to control rabbit populations, although it is important to consult with local authorities before using any poisons.

They impact threatened plant species
Rabbits are herbivores and eat a wide variety of plants, including crops, roots, pastures, young trees, and vines, and they prefer short, succulent plants with high nutritional value. They also graze very close to the ground, which weakens perennial grasses and can eliminate them from established pastures. This can then lead to the pasture being invaded by broadleaf weeds and annual grasses, making it less suitable for livestock production.
Rabbits inhabit 70% of Australia's landmass, and their feeding habits have impacted 75 Commonwealth-listed threatened plant species and five threatened ecological communities. They have also been listed as a key threatening process to threatened species conservation under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). As few as 0.5 rabbits per hectare can be enough to prevent the regeneration of several threatened or endangered plant species. Forestry and tree plantations can suffer extensive losses due to rabbit grazing, and the resulting erosion caused by denuded vegetation can impact dam catchments, water supplies, and maintaining topsoil.
Rabbits selectively feed on certain plant species at critical stages of their life cycle, such as seeding and seedling establishment. This severely affects regeneration and can cause soil erosion. It may also encourage the dominance of noxious or unpalatable weed species. In Victoria and Tasmania alone, rabbits cost $30 million in lost production for the beef, lamb, and wool industries per year.
Given the damage that rabbits do to the habitat, it makes environmental sense to harvest them from the wild for human consumption. However, the vast majority of rabbits sold as meat products in Australia are farmed and often raised in cages. Food safety regulations prohibit the use of wild meat for human consumption unless processed in an approved abattoir, limiting hunters' ability to sell wild-harvested rabbits.
