​​Autumn Conservation: What to Plant, Protect and Preserve This Season

As the heat of summer fades and Australia’s landscapes transform with the arrival of autumn, this season presents unique opportunities for conservation action. While many think of spring as the prime time for environmental work, autumn conservation action is equally crucial for supporting our native ecosystems.

Here’s your guide to making the most of this transitional season for nature through what you choose to plant, protect and preserve.

What to Plant This Autumn

Autumn’s cooler temperatures and typically higher rainfall create ideal conditions for establishing native plants. The mild weather allows roots to establish before winter’s chill, setting plants up for strong growth come spring.

🌱 Native grasses and groundcovers are particularly well-suited to autumn planting. Species like kangaroo grass (Themeda triandra) and wallaby grass (Rytidosperma species) establish beautifully during this season, providing crucial habitat for small mammals, insects, and ground-dwelling birds throughout winter.

🌱 Mid-story shrubs such as kangaroo paw (Anigozanthos species) and native daphne (Pittosporum undulatum) can be planted now, giving them months to develop root systems before the demands of summer. These plants create the essential habitat layers that support diverse wildlife communities.

For those participating in CVA’s Urban Shade Forests initiatives, autumn is prime time for planting. Since 2022, this program has established over 20,000 seedlings across urban areas, creating vital green corridors that combat the urban heat island effect while providing habitat for native species.

What to Protect

As temperatures drop, Australia’s wildlife face new challenges that require our attention and protection.

💦 Wetlands need particular focus during autumn. These critical ecosystems support hundreds of waterbird species in Australia, but approximately 50% of Australia’s wetlands have been lost since European settlement. Autumn’s transitional water levels make wetlands vulnerable to degradation. Participating in wetland restoration projects, removing invasive weeds like willows and blackberries, and reporting pollution incidents all make meaningful differences.

🐨 Endangered species require heightened protection as they prepare for winter. The Eastern Barred Bandicoot, which has an incredible story of survival from the brink of extinction, depends on protected grassland habitats during autumn’s breeding season. Supporting predator-proof fencing projects and participating in habitat restoration work directly contribute to their survival.

🦩Migratory bird pathways deserve protection as species travel along the East Asian-Australasian Flyway. Autumn sees thousands of shorebirds departing Australian wetlands for northern breeding grounds. Protecting coastal habitats from disturbance and removing marine debris ensures these incredible journeys can continue.

What to Preserve

Preservation extends beyond single species to encompass entire ecosystems and the ecological processes they support.

🐝 Preserve pollinator corridors by maintaining native flowering plants through autumn. Many Australian native bees and other pollinators remain active during cooler months, and continuous flowering resources support their survival. Plants like native everlastings and billy buttons provide crucial late-season nectar and pollen sources.

🌱 Preserve seed banks by collecting and storing seeds from healthy native plants during autumn. This season offers abundant seed collection opportunities from summer-flowering species. Proper seed collection, storage, and sharing through community seed banks preserves genetic diversity and supports future restoration efforts.

💭 Preserve traditional knowledge by engaging with Indigenous land management practices. Autumn was traditionally a time for cool burns in many Aboriginal communities, reducing fuel loads while promoting native plant regeneration. Supporting Indigenous-led conservation projects honours these time-tested ecological practices.

Taking Action This Autumn

Conservation volunteering during autumn offers comfortable working conditions and visible impacts. From planting events at Woodlands Historic Park in Victoria to wetland restoration in coastal New South Wales, opportunities to take action for nature during the autumn of 2026 exist across all Australian states.

Every action counts toward building resilience in our ecosystems. Whether you’re planting a native garden in your backyard, joining an organised conservation project, or simply learning more about your local environment, autumn provides the perfect season to deepen your connection with Australian nature.

This autumn represents thousands of opportunities to plant, protect, and preserve the landscapes and species that make Australia unique. The work we do now, during these cooler months, creates the foundation for thriving ecosystems year-round.
