Why Does it Matter

Biodiversity is the very fabric of the Earth. It is diversity in plants and animals that enables ecosystems to function. Yet, one eighth of the world’s species – more than a million – are threatened with extinction.

In Australia, we are renowned for our unique wildlife with more than 70% of our species (69% of mammals, 94% of amphibians, 46% of birds and 93% of reptiles) found nowhere else on earth. But, we also have the highest rate of vertebrate mammal extinction in the world.

The greatest threats facing our plants and animals are changes in land and sea use; direct exploitation of organisms; climate change; pollution; and invasion of alien species.

Earthwatch is working with scientists and communities to understand the declines and how we might all take part in reversing them, so that we can live in balance with nature.

How is Earthwatch Making a Difference?

Bush Blitz

Bush Blitz is Australia’s largest nature discovery project – a unique multi-million-dollar partnership between the Australian Government, BHP and Earthwatch Australia. Earthwatch places Australian primary and secondary STEM teachers and geography as research assistants on Bush Blitz expeditions.

Tiny Forests

Tiny Forests are dense native forests about the size of a tennis court. Using an effective planting method involving soil enrichment and a dense planting structure, Tiny Forests grow up to 10 times faster than traditional forests and become up to 100 times more biodiverse than monoculture forests. 

Get involved

You can get involved through our many projects aimed at conserving key areas and furthering research.


Recovery of the Great Barrier Reef

Mitsubishi Corporation and the Australian Institute of Marine Science work to fill knowledge gaps that will help reef managers to make evidence-based decisions about active interventions.

This will support the Great Barrier Reef’s recovery, and the recovery of reefs around the world.


Eco Systems of the Murray River and Mallee

Calperum Station, a transformed pastoral region, has been undergoing substantial social, economic and environmental change over the past 100 years. The station provides an excellent opportunity to study ways in which to best manage changes in semi-arid and arid systems. Working with Australian Landscape Trust, teams from corporate, student and teacher backgrounds partake in research focused on carbon, water and biodiversity responses to the changing land use.
