Every September, communities across Australia mark Biodiversity Month, a national celebration of the country’s plants, animals and ecosystems. For schools, the timing is generous. National Wattle Day opens the month on 1 September. National Threatened Species Day follows on 7 September. World Rivers Day closes it on the last Sunday of the month. Behind the calendar sits a bigger story. Australia holds a share of global biodiversity that few nations can match, and much of it survives nowhere else on Earth. Educators, school leaders and policy makers sit closer to the solution than many of them realise.

A Mega-Diverse Nation With a Global Responsibility

Australia is one of only 17 mega-diverse countries recognised by the United Nations Environment Program’s World Conservation Monitoring Centre. Together, these nations cover roughly 10 percent of the Earth’s surface yet account for more than 70 percent of the planet’s total biological diversity, a concentration documented by the national reserve system. Within that group, Australia alone accounts for roughly 7 to 10 percent of all species on Earth across approximately 5 percent of the planet’s land area. The numbers behind that status are striking. Around 87 percent of Australia’s 316 terrestrial mammal species live nowhere else. Roughly 85 percent of the country’s plant species are endemic. Some 93 percent of its reptiles are unique to the continent, which holds more reptile species than any other nation.

Scientific discovery continues at pace. In 2020 alone, taxonomists named 763 new Australian species, including 297 insects, 166 fungi, 77 plants and 21 vertebrates. Students learning science today will work alongside a national species list that is still growing. This uniqueness carries real weight. When a species exists only in Australia, its survival depends entirely on Australian decisions. That responsibility extends to classrooms, council chambers and curriculum committees alike.

Ecosystems as Life Support, Not Scenery

Biodiversity is commonly framed as a conservation issue. However, it is more accurate to frame it as infrastructure. Local ecosystems provide clean air, fresh water, fertile soil, crop pollination and food. As a result, health, wellbeing and the national economy all rest on these services. This framing matters for education. When students understand that a wetland filters their drinking water and that native bees pollinate their food, biodiversity moves from an abstract topic to a practical one. Furthermore, it connects science, geography, economics and civics in a single thread. The connection also builds resilience thinking. In turn, a generation that understands ecosystem services will make better decisions about land use, water management and urban planning than one that learned biodiversity only as a list of animal names.

The Hard Numbers Behind Threatened Species Day

National Threatened Species Day on 7 September marks the anniversary of the death of the last Tasmanian tiger in 1936. The date now carries almost 2,000 listed threatened plant and animal species with it. The record is sobering. Australia has lost more mammals than any other country since colonial settlement. In total, 100 endemic species are listed as extinct or extinct in the wild since 1788. About 10 percent of endemic terrestrial mammals have disappeared in the past 200 years. Moreover, roughly 21 percent of those remaining are assessed as threatened. Since 2022, an additional 163 species have joined the threatened lists.

There is, nonetheless, genuine momentum. The Australian Government is investing over $600 million in threatened species protection through the Saving Native Species Program, the Natural Heritage Trust and the National Environmental Science Program. Additionally, the updated Australia’s Strategy for Nature 2024 to 2030 gives governments, businesses and communities a shared roadmap aligned with the Global Biodiversity Framework. Schools can bring this history to life in accessible ways. The community-driven Threatened Species Bake Off, for example, invites students to decorate cakes as endangered animals, turning a difficult topic into a memorable one. Playfulness and seriousness work well together in environmental education.

Practical Ways Schools and Communities Can Take Part

Biodiversity Month rewards participation over observation. Hundreds of community events run throughout September, from tree planting days and wildlife walks to citizen science projects and family biodiversity festivals. Importantly, the entry points are simple and low cost. One practical starting point is spending 20 minutes a day in nature. A daily walk on local trails builds observation habits and supports student wellbeing. Teachers can also turn this into structured nature journaling across primary and secondary levels. Another accessible step is planting local native species. School gardens and backyards planted with regional natives support bees, birds and small wildlife.

Wattle Day on 1 September offers a natural starting point, with more than 1,000 native wattle species to explore. Students can also log their discoveries with iNaturalist. This free identification tool lets students photograph and record local species, contributing real data to national biodiversity records. The process is authentic citizen science, and it counts. Finally, schools and families can draw on official resources. The Biodiversity Month program from the Department of Climate Change, Energy, the Environment and Water provides current event listings, teaching materials and updates.

The Future Implication: Environmental Literacy as Core Business

The trend line is clear. Without sustained intervention, extinction rates of one to two mammal species per decade will continue. Policy investment helps, and community action helps too. The most durable variable, however, is education. Students in Australian classrooms today will inherit both the responsibility and the tools. They will vote on environmental policy, manage land, design cities and raise the next generation of citizens. Whether they treat biodiversity as core infrastructure or as background scenery depends largely on what schools teach now.

For school leaders, the opportunity is to embed biodiversity across the curriculum rather than confining it to a single science unit. Similarly, for policy makers, the opportunity is to fund the programs, excursions and citizen science platforms that make environmental literacy practical. September offers the invitation. A wattle in bloom, a bake off for a bilby and a walk along a local river are small acts. Repeated across thousands of schools, they build a nation that understands what it holds and what it stands to lose.
