Biodiversity on farm plays a vital role in strengthening drought resilience by supporting more stable, adaptable, and productive ecosystems. A diverse mix of plants, animals, insects, and soil organisms helps improve soil health, enhance water cycling, and maintain ecosystem functions even during periods of limited rainfall. This diversity can buffer farms against drought impacts by reducing reliance on a single species or system, increasing natural pest control, and improving the overall capacity of the landscape to recover after stress.

By encouraging biodiversity, farms can create more resilient systems that better withstand environmental variability and support long-term productivity. Diverse plant communities, in particular, can improve groundcover, root structure, and soil organic matter, all of which contribute to better moisture retention and reduced erosion during dry conditions.

Key ways biodiversity supports drought resilience include:

Improves soil structure and health through a wider range of plant roots and soil organisms
Enhances water infiltration and retention across the landscape
Supports natural pest control and pollination, reducing reliance on external inputs
Increases ecosystem stability and reduces vulnerability to extreme weather
Encourages faster recovery of pastures and crops after drought conditions ease

Increasing biodiversity on farm involves creating and maintaining a variety of habitats and species that work together to support healthy, resilient ecosystems.

Plant a diverse mix of pasture and crop species, including deep-rooted and perennial varieties
Retain and protect native vegetation, shelterbelts, and remnant habitat areas
Re-establish native plants to improve habitat connectivity across the farm
Implement rotational grazing to allow pastures to recover and regenerate
Reduce chemical inputs where possible to support beneficial insects and soil organisms
Protect dams, waterways and wetlands to support a wider range of species and ecosystem functions
Maintain groundcover year-round to support soil life and reduce habitat loss
