Conservation starts in your backyard. The plants that we choose for our gardens can provide most, sometimes even all, of the food, shelter and nesting resources that urban birds require. So when you are deliberating over which plants to add your garden, it’s useful to consider the following.
Before you start planning, take into account the plants you already have and which birds are using them. Instead of removing vegetation straight away, add new vegetation to provide some resources that you might otherwise be missing and to attract new birds to your patch. Remember to make sure there is readily available water and plants that flower at different times throughout the year. That way, your local birdlife will never go hungry or thirsty.
Plants that grow naturally in your area are suited to local conditions. They will provide the right food and shelter for local native birds, unlike some hybrids or plants from other parts of Australia, and are less likely to become weeds in adjacent bushland areas. If you can’t get locally native plants, general natives are the next best thing.
When selecting plants you don’t want a flush of flowering and then nothing for the rest of the year. Instead you want to have different plants flowering/fruiting/seeding throughout the year so there is always something happening.
Planting a mix of plants that provide these different resources in different seasons will encourage birds to visit throughout the year.
Australian native plants have evolved in poor soils and are very sensitive to artificial fertilisers, especially phosphorus. Generally, clay soils are naturally fertile and shouldn’t require any added fertiliser, while sandy soils are low in fertility as nutrients leach out with fast drainage. Only use low-phosphorus fertilizers especially formulated for Australian native plants or mulch instead. Both clay and sandy soil types respond well to thick layers of organic matter used as mulch.
Mulching helps to maintain soil moisture and reduces or eliminates the need to water artificially. In addition, as mulch breaks down, nitrogen and potassium are replenished in sandy soils. Mulch also provides humus (nutrient-rich earth formed when plant or animal material decays), which improves the soil, and can reduce weed growth.
Many local councils provide guides for planting indigenous plants in your garden, which can help attract native birds.
Habitat clearance and degradation are major threats to black-cockatoos in south-western Australia, with development rapidly reducing their remaining habitat around Perth. You can help black-cockatoos by planting native plants in your garden, or when replanting your local reserve.
