Dr Grey Coupland of Pocket Forests WA.
Some of us grew up cradling slaters—or, as we called them, butchie boys—while keeping a cautious distance from earwigs, warned by adults they might crawl into our ears and eat our brains.
Afternoons were spent kicking a soccer ball beneath the shade of trees while the grouchy man next door yelled at us to get off his lawn. The PlayStation stayed off after school; boredom—no matter how whiny the protests—was met by knocking on neighbours’ doors to ask if the kids could come out and play.
Connection to the natural world wasn’t just our play world—where bikes raced up and down quiet streets and days ended covered in dirt, sweat and the unmistakable smell of being outside—it was also what brought us together.
But those neighbourhoods slowly began to change as development crept in—a pattern particularly evident in the suburbs of Perth, Western Australia. Houses packed tightly together, and green space was reduced to open ovals, stripped of their wildness.
A sense of sameness replaced any true sense of place, and the awe and unspoiled beauty of the natural world seemed to retreat further outward—to places such as the Perth Hills.
For one mother and ecologist based in Perth, that shift became impossible to ignore. When she had children of her own, it sharpened her long-held affinity with the natural world into something more urgent—a desire to restore and rewild urban environments to resemble the landscapes that once existed there.
As her work rewilding city spaces with the Miyawaki method—adapted for Australian landscapes—gained momentum, she noticed another pattern emerging: a growing disconnect between children and the natural world across Perth. What began as a mission to restore urban nature gradually expanded to include something more—to help children reconnect with it.
Dr Grey Coupland of Pocket Forests WA.
The Biophilic Blueprint sat down with Dr Grey Coupland to explore Pocket Forests WA, a program based on The Miyawaki Method—a Japanese approach to rewilding spaces.
Her journey began with curiosity, quickly evolving into a hands-on mission to bring biodiversity and connection to urban spaces.
"I hadn't heard of a Miyawaki forest before. I came across a World Economic Forum post talking about how we can revegetate our urban landscape with these small pockets of native plants to increase biodiversity and impact on the wellbeing of people living in cities,” Coupland said.
"I took a deep dive into what a Miyawaki forest is and the history and how the methodology came about. And as I read more, I became more and more intrigued, and it all went from there."
"Now I'm trying to bring biodiversity back and revitalise our urban areas for urban greening, so that people can reconnect with nature for health and wellbeing as well."
The Miyawaki forests, or “pocket” forests, are part of a dedicated science program run by the Harry Butler Institute at Murdoch University in Perth. Through the program, small pockets of land are transformed into dense, living ecosystems. The forests do more than greening the landscape—they’re cooling spaces, rich biodiverse sanctuaries and they have been altered to suit Australia’s unique landscape.
Coupland leads the program as a research fellow at the Institute. She is an urban (or restoration) ecologist who began her career as a marine ecologist, studying seagrass and mangrove systems, before gradually shifting her focus onto land.
When she had her two sons, Coupland said it sparked a deeper desire to focus on regenerating urban spaces. “I thought, we really need to do something about our urban space, because we—in Perth in particular—have a huge urban sprawl, and there's a lot of Urban Heat Island (UHI) effect. We're also losing a lot of habitat for our native organisms.”
The urban heat island (UHI) effect occurs when cities become noticeably warmer than surrounding areas, as hard surfaces like concrete and asphalt absorb and re‑radiate heat while a lack of vegetation limits natural cooling.
Urban canopy cover has a direct effect on people’s daily lives, Coupland explains.
"What we see in these northern suburbs and southern suburbs (in Perth), where there is no canopy left, is that people can't go outside on hot days to exercise or join in the community and activities because it is too hot. It's dangerous. Heat is the silent killer that we have in our cities now.”
In suburbs with few trees, residents often struggle to exercise, socialise or even walk safely during hot days.
“There's an equity issue,” Coupland tells The Biophilic Blueprint. The loss of canopy also leaves wildlife with fewer refuges from extreme temperatures.
Beyond this, a lack of trees and wild nature limits daily human contact with the natural world—a contact that plays an important role in restoration, stress reduction, spiritual connection and physical health.
Urban Growth and Its Impacts on Human and Environmental Wellbeing
Perth has some of the lowest urban tree canopy cover of any Australian capital city. Vegetation mapping for the Perth and Peel regions recorded around 16 percent canopy in 2020—well below aspirational targets and other major cities. The latest 2024 data shows 20–22 percent, but this reflects a new, more accurate measurement method, rather than a true increase in trees (Western Australian Planning Commission, 2026).
This low canopy cover reflects broader changes in land development. As urban areas have grown and densified, older trees have often been removed to make way for housing and infrastructure, leaving behind expanses of heat‑absorbing surfaces such as roads, rooftops and pavements.
The appearance of the Polyphagous shot-hole borer in Western Australia in late 2021, and the ongoing management efforts—which have already resulted in the removal of more than 3,000 trees—has added further strain to Perth’s rapidly declining urban forest.
Beyond the city, extensive land clearing for farmland across Western Australia has further impacted natural ecosystems.
"It was a bit of a wake-up call to me to the kind of place I want my boys to grow up in and what they wanted to live in. I looked around, and I was concerned. So, that's why I came onto land, to work on our urban landscape … to improve it,” Coupland said.

Planting the Seeds of Stewardship: The Miyawaki Approach in WA
Coupland’s work, largely focused within schools, responds to a critical need for more wild spaces in urban areas—and reconnects the next generation with nature in a way that is hands-on, local and lasting.
The program also engages citizen scientists through a dedicated science outreach program that is one of the 157 UNESCO "Green Citizens" programs. Students plant their own Miyawaki forests on school grounds and monitor them monthly with the Harry Butler Institute’s Team Forest, becoming citizen scientists and fostering a sense of stewardship.
To date (2026), 22 forests have been planted as part of the program, 17 of them in schools. "I see schools, and reaching out to primary school age children is important, because often we see a disconnect for children from nature. They're often really focused on their screens. That's not necessarily through fault of their own, it's just the way society has taken them,” Coupland tells The Biophilic Blueprint.
The first pocket forest, located at South Padbury, was planted in 2021 by 106 schoolchildren on a 100 m² section of the school grounds. The project was a collaboration with SUGi and The Seedling Bank as part of National Tree Day.
"The children I work with, some of them have never planted a plant before. Some of them have never played in the dirt before. And when I first started doing this, I was actually quite surprised and a little bit shocked.”
“The disconnect from nature is worrying,” Coupland says. “If you don’t have a connection with nature as a child, you’re very likely not going to be interested as an adult. The next generation are going to be the custodians of our planet. We need to help reconnect children with nature so they feel affinity with it, so they’re more likely to fight and try and preserve it when they get older.”
By educating and involving the next generation in planting and caring for pocket forests, the program is cultivating the way for an urban greening strategy that not only plants life back into urban spaces—but also restores elements of the ecosystems that once existed there—a core principle of the Miyawaki method.
Japanese botanist Dr Akira Miyawaki.
The Miyawaki Method—from Japan to Australia
The Miyawaki method, developed in the 1970s by Japanese botanist Dr Akira Miyawaki, grows compact, thriving “tiny forests” using only native plants. By planting a rich mix of local saplings closely together on revitalised soil, these forests establish quickly, becoming denser and more biodiverse than conventional tree planting.
Within just a few years, they form self-sustaining ecosystems that require minimal maintenance—offering a powerful tool to restore nature in cities, reconnect communities with green spaces and support thriving wildlife.
This method is inspired by ancient sacred shrine forests in Japan, known as Chinju-no-mori. These forests were protected for centuries, providing valuable examples of what healthy ecosystems look like when they are allowed to grow with minimal human disturbance.
Scientifically, the method is based on two key ecological ideas. The first is successional vegetation ecology, which explains how plants naturally grow and change over time—from early pioneer species to mature forests. The second is potential natural vegetation (PNV), which refers to the plant communities that would naturally exist in a place if human disturbance were removed.
In practice, the Miyawaki Forest Method doesn’t wait for natural regeneration to occur slowly over decades. Instead, native trees are densely planted at the beginning, and the site is carefully managed during the early years to help the forest establish. After this stage, ecological processes take over, allowing the forest to develop with minimal ongoing intervention.
These scientific principles form the foundation for how Miyawaki forests are planted and managed.
"Dr Akira Miyawaki came up with the method and planted thousands of forests across Japan and Southeast Asia. From there, the method spread to Europe, and is now being used in Australia, South America, and many other places around the world."
"But of course, the Miyawaki method was originally designed for Japanese evergreen forests, which are very different from the systems we have here. In particular, Perth has a very unusual ecological system.
"We have the Banksia woodlands—currently listed as endangered under federal protection, though many believe they should be classified as critically endangered. This woodland system is unique to the southwest and relies on specific native species. They are very particular about how they can be replanted and restored, especially because many plants in this system, such as the Proteaceae species, are sensitive to high phosphorus levels in the soil."
The Banksia woodlands of the Swan Coastal Plain are a unique ecological system in southwest Australia, but over half have been cleared in the past century and the remaining fragments continue to face ongoing threats. Many of these woodlands are now listed as endangered under federal law, though some argue they should be classified as critically endangered (Van Etten & Slee, 2022; Urban Bushland Council WA Inc.).
Why Forests Matter for People and Planet
Forests are more than just trees—they are living, breathing hubs of life that sustain both the planet and people.
“Forests have the highest biodiversity on land—they're like the coral reefs of the landmass. They contain the most species globally on land,” Coupland explained. She said soils in forests are crucial, even for individuals. “Even if we don’t see forests in our urban landscapes, they play a vital role in the functioning of the world’s ecosystems and the health of the planet as a whole. Forests along the coastal fringes of land masses also help seed clouds… for allowing rain.”
They serve as critical habitats for maintaining Earth’s biodiversity, she said. “Biodiversity has huge effects on us—on our wellbeing, on food security, and on maintaining a diverse genetic pool.” Coupland also highlighted the role of soils and microbes within these ecosystems: “The microbes in the soil, and trying to maintain them, are sources of carbon sinks.”

Three important elements of a Miyawaki forest:
1. Locally Native Species
“The pocket forests are comprised of locally native species. This is what Professor Miyawaki called ‘Potential Natural Vegetation (PNV)’. It is what would have been on the site that you're proposing to put the forest … before the site was cleared.”
“We don't include ground covers, and we don't include grasses in a Miyawaki forest, because they're very fast-growing, and they all tend to dominate the canopy species. We have to be a bit careful about that."
Coupland also emphasises planting at high density: three plants per square meter. "The high density is said to encourage rapid growth of these things, so you get rapid maturation of these forest systems."
2. Soil Remediation
"When we come to the Miyawaki method, there's an extensive soil remediation process because we're working in urban areas, and the soil is devoid of life because we've done such horrible things to it," Coupland explained.
She said the soil remediation reinvigorates the soil, bringing life back to create optimal conditions for plants to grow before they are planted at high density.
“Part of the process is to reinvigorate the life in that soil and add microbes back in. But we have to be careful about how much in the way of nutrients we add, because the proteas won't like it. I’ve modified how we reintroduce nutrients in the soil. The focus primarily is adding microbes into the soil to help kickstart the system, so that the plants can have a really good start in life."
Once the soil is prepared, Coupland plants at a high density—around three plants per square metre. "The high density is said to encourage rapid growth of these plants, so you get rapid maturation of these forest systems," she said.
3. Species from Place
"But the really critical part is making sure you get that species mix right," Coupland said. "It has to be the locally native plant species and nothing else, and nothing from different locations, or from fruit trees—only locally native plant species."
She explained that using locally native plants is essential for creating a self-sustaining ecosystem. These species are adapted to the local climate, soil and seasonal conditions, which allows the forest to thrive with minimal ongoing maintenance. Introducing plants from other regions or non-native fruit trees can disrupt the balance of the ecosystem, outcompete native species and even reduce the forest’s ability to support local wildlife.
Getting the species mix right also ensures that the forest reflects the “potential natural vegetation” of the area—the plants that would have naturally existed on the site before it was cleared. This careful selection is what allows Miyawaki forests to regenerate quickly, support high biodiversity and reconnect urban spaces with local ecology.

Pocket Forests as an Urban Greening Strategy
"When you plant the pocket forests, they grow super-fast, and within six months, you've got these little forests growing. Within that short space of time, you can see the life coming back. You can see the biodiversity as you used to see it," Coupland said.
She explained that the return of life is immediate and remarkable. “You see all these invertebrates coming in, and after forests have been established for a while, invertebrates take root and increase in abundance. And other things come in, like birds. We even had Gwenda footprints in some of our forests. And we've got bobtails that have come in."
The ecological impact is mirrored by the social impact. "It's pretty exciting to see this. That's one side of things—the increase in biodiversity and seeing the kids really enjoying their forests. They have a strong sense of ownership over their forest. They like to report back on what they've seen. I find that very rewarding seeing that they're enjoying the natural space that they have created."
Coupland emphasised that witnessing both biodiversity and community engagement highlights the dual benefits of the program: the forests are not only restoring native ecosystems but also fostering environmental awareness, curiosity and stewardship in the next generation.

Reconnecting Children’s affinity to Nature (biophilia)
Coupland says that the children who had little prior engagement with nature often feel a bit nervous when they first come to plant a forest and get their hands dirty. "But once you've shown them the plant, dug the hole, and they can see what's going to happen, they start to get more enthusiastic," she explained.
“By the end of the day, some of those children have planted 4, 5, 6 plants. When we go out to do the monitoring afterwards, that's when you really start to see that connection happening,” she says joyfully.
Coupland tracks the pocket forests, still visiting the very first one planted at South Padbury Primary School—a school in Perth’s northern suburbs on the Swan Coastal Plain. This was the first forest in the program and the first in W.A. The site was once a Banksia woodland community.
"I'm still going back there to monitor with the kids and doing my own monitoring. We keep tracking all the forests over time, see how well they're performing, and what animals are coming in. We do environmental DNA work on the soil, bird surveys, and all sorts of testing.
"We take learnings from all the previous forests and apply them to the new ones, and publish data and try to disseminate the information to the broader community through public talks, going to academic conferences and publishing manuscripts. There's a lot in the program to educate young people about the benefits and the importance of these systems."
She said at first the children start looking for their own plant in the forest but as the the forest matures, they start looking not just for their own plant, but how everything is growing and working together.
“They see what’s happening in the forest, and how the whole forest is growing and all the different animals that are coming in to use their forest and how the forest is cooling the area. They start to get more enthusiastic, and they start to recognise plants. They start to recognise bugs. Some that had no idea what a cockroach looks like—or an earwig.”
“By the end of a few monitoring sessions, they can readily identify these things. And they start to name the local birds. I can see that reconnection with nature happening, and it's very inspirational to me to see the children regaining their affinity with nature."
"I've got a PhD student who's looking at the wellbeing of children who are working in the Miyawaki forest program, seeing how well they're re-engaging with nature, how that's influencing their wellbeing, and how that might influence what they do outside of school. Are they going to be more likely to plant in their garden? Can they identify birds and things? Are they interested in going for bush walks now? It is exciting to see what is unfolding."

Inspiring Action Beyond Schools
Beyond the schools, the impact of these forests extends into the wider community. Children are not the only ones re-engaging with nature—residents of all ages can feel the benefits and take action themselves.
"People feel very invested in these forests, and they're very joyful things to help reconnect people with each other, reconnect people with nature and give people a sense of civic pride that they've created something beautiful. The benefits that people can get from these forests are quite incredible.”
Coupland reflects on the broader potential of these forests: “We've demonstrated the effects these forests can have on increasing local biodiversity and showing the public that they have the capacity to make a difference. If each and every one of us planted a small patch of Banksia woodland—one of these little forests in our backyard or on our verge—we could start to see real change.”
The Pocket Forests initiative provides a practical strategy to combat urban heat while demonstrating how small, dense forests can reimagine tree planting—turning urban greenery into vibrant hubs for biodiversity, community connection and local climate resilience. Efforts are now underway to reverse Perth’s low canopy cover, with tree-planting strategies and urban greening plans aiming to boost canopy cover. WATCA, for example, is advocating for a Tree Canopy Target of 30 percent by 2040 to improve heat resilience, biodiversity and overall liveability.
The State Government is committed to its ambitious target of increasing Perth and Peel’s urban tree canopy to 30% by 2040.
She continues, “If all of us got together and did that across our urban landscape, imagine the incredible difference we could make. It gives me goosebumps to think about it, because if everyone rewilded part of their verge, we could create pollinator highways and provide habitat and resources for all our amazing species that can live in urban areas.”
“This is a really important part of the work—showing that everyone can make a difference. No matter how big a space you have, even if it's just a balcony, you can plant some pollinator food. No matter the size of your area, you can actually make a difference.”
Alignment with The Biophilic Blueprint
The Pocket Forests WA program aligns with The Biophilic Blueprint’s mission by fostering a hands-on, lived relationship with nature. It reconnects children and communities with biodiversity, demonstrates practical ways to restore urban ecosystems, and promotes mental and physical wellbeing through nature engagement. The program shows that biophilic design is not just about aesthetics—it’s about restoring ecological function, improving human health and cultivating the next generation of nature stewards. By integrating ecological restoration into everyday urban spaces, Grey Coupland’s work exemplifies how science, education and community engagement can co-create a greener, healthier future.
