Tiny Forests

Tiny Forests are densely packed patches of native bushland the size of a tennis court, right in the heart of our cities. These urban wildlife oases are a unique nature-based solution, reconnecting people with nature and helping to mitigate our urban climate and biodiversity challenges. Using an established planting method (called the Miyawaki method) that includes soil enrichment, diverse indigenous plant selection, and a dense planting structure; Tiny Forests are supercharged, growing up to 10 times faster than traditional forests, and becoming up to 100 times more biodiverse than monoculture forests.

Earthwatch is championing Tiny Forests in Australia, and engaging the local community to help plant, maintain and conduct important research, to better understand the benefits these tiny and mighty forests provide

Get Involved: Community Planting Day

We are building our first Tiny Forest in the heart of West Pymble!

Community Planting Day

Sunday 16th June 9.30am
West Pymble Village Green, , NSW 2073

The Ku-Ring-Gai Tiny Forest is made possible thanks to a collaboration between Earthwatch and Ku-Ring-Gai Council, in partnership with Bupa.

We invite you to come along and help build our brand-new Tiny Forest.

No planting or gardening skills required. Just a desire to help your local environment and community. Don’t forget weather appropriate clothes, closed toe shoes and BYO gloves, if you have them.

Tiny forest planting

Step 1:


We plant dense, fast-growing native bushlands, based on an established forest management method.

Tiny forest engaging

Step 2:


We engage business and community to cultivate and monitor each forest over time. This connects people with nature and raises awareness of biodiversity loss and climate change.

Tiny forest collecting

Step 3:


We collect environmental and social data relating to every forest we plant, to assess the benefits they provide over time and between forests.

Program Outcomes

  • Accelerated growth rates
  • High biodiversity
  • High density
  • Thermal cooling
  • Improved soil moisture, texture and health
  • Stormwater mitigation
  • Student and teacher education space
  • Community space for education and nature connection
  • Improved community wellbeing and liveability

Why Tiny Forests?

Sustained urban land clearing and the decline of green canopy in Australia has caused habitat fragmentation, species extinction, biodiversity loss and rising urban temperatures. Major heatwaves are Australia’s deadliest natural hazards, particularly for cities, with a lack of trees creating “heat islands”. With 68% of Australia’s population predicted to live in cities by 2050, our cities may soon become unliveable.

Nature-based solutions for urban resilience, such as Tiny Forests, engage and educate the community in understanding the true value of biodiversity, and how individuals can play an important role in contributing to the urban forest.

The Research

Tiny Forest establishment follows a particular planting method, called the Miyawaki method, including adaptions of the method to suit the Australian context and local site conditions.

The Miyawaki method was first developed in the 1970s by Dr Akira Miyawaki, and it is a particularly valuable method for urban greening. The combination of soil enrichment and a dense planting structure results in accelerated growth, about 10 times faster than traditional forests. As the forest establishes and thickens, biodiversity levels rapidly increase, and the maintenance requirements decrease.

Through structured and facilitated citizen science days, data will be collected in the following areas to help understand the benefits of the planting methodology:

  • Biodiversity (pollinators and ground dwellers)
  • Soil moisture, and soil texture
  • Growth rate and carbon content
  • Thermal comfort
  • Feedback and wellbeing survey

We are thrilled to announce that we are proudly partnering with Bupa for the development of our Sydney and Monash Tiny Forest sites.

This collaboration is made possible through the generous support of the Bupa Healthy Planet, Healthy People initiative. Planting is scheduled to take place in May, stay tuned for more updates around this unique corporate engagement partnership. Read more here.

It’s long been understood that getting active in nature is good for both your physical and mental health. That's why we're so pleased that the millions of steps our people took in 2023 has unlocked funding for amazing biodiversity projects such as Tiny Forests. We hope these green spaces will be enjoyed by local communities for generations.
Roger Sharp, Bupa APAC Chief Sustainability and Corporate Affairs Officer
There is a strong need to invest in robust nature positive solutions to climate change in our cities and towns so that communities and nature benefit. Corporate investment from organisations like Bupa are integral to driving the Tiny Forest movement in Australia.
