Miyawaki Tiny Forests: Rapid Reforestation in Small Urban Spaces
A Miyawaki Tiny Forest is a high-density, ultra-diverse “pocket forest”. Invented in Japan, this method is increasingly being used in urban spaces around the world as a planting method able to quickly increase canopy in cities.
By prepping the soil and planting young native trees, shrubs, and wildflowers very close together in layers, we mimic how a wild, old-growth forest works. Because the plants are so close, they “compete” for sunlight and grow 10 times faster and 30 times denser than a regular park or backyard. Within just a couple of years, it becomes a self-sustaining ecosystem that takes care of itself.
Why Tiny Forests Work
Rapid Growth and High Density
Because we plant 3 to 4 trees per square meter, the saplings compete for sunlight, which triggers them to grow upward much faster than usual. A Miyawaki forest can reach maturity in about 20 to 30 years, compared to 150 to 200 years for a natural forest.
Massive Biodiversity Boost
By planting a huge variety of native species (trees, shrubs, and groundcovers), we create a “layered” habitat. This attracts a much wider range of insects, birds, and pollinators than a standard lawn or a row of identical street trees.
Natural Air Conditioning (Urban Heat Island Mitigation)
The dense canopy of a tiny forest provides significant shade and releases moisture into the air through transpiration. In the middle of a hot Aylmer summer, the temperature inside or near a tiny forest can be several degrees cooler than the surrounding pavement.
Better Water Management
Instead of rainwater running off into our sewers, taking pollutants with it, the forest absorbs the water, recharges the groundwater, and prevents local flooding.
Carbon Sequestration and Air Quality
A tiny forest has a much higher leaf-surface area than a traditional garden. This greatly improves its ability to absorb CO2, and filter out urban dust and pollutants. As the trees grow, they pump carbon through their roots and into the soil, where it is “locked away” by a massive network of fungi and microbes.
Air Quality and Sound Barriers
Tiny forests act as high-performance filters in an urban neighborhood. The dense foliage traps urban dust, smoke, and pollutants. Because the planting is so thick, the forest also acts as a natural sound barrier, soaking up the noise from nearby traffic or construction.
Creating Immediate, Deep Shade
The multi-layered structure of a tiny forest creates a “cool room” effect very quickly. By planting densely, we create a canopy that overlaps, providing deep, dark shade that protects people (and pets!) from harsh UV rays.
Do you have access to a public greenspace we could transform? Whether it’s a schoolyard, park, or community lot — reach out. We’d love to chat about planting a tiny forest together.
Our Living Learning Lab
Our flagship Tiny Forest is located at the Localeaf Gardens Learning Lab. This is where our volunteers help us track growth, monitor soil health, and care for the forest saplings as they establish their roots.
Everything we do is rooted in “learning by doing.” We observe how different species interact and document the results so we can refine our methods for the rest of the community.
Grown Locally, Planted Together
This season, we have two new Tiny Forests planned for the Aylmer area. What makes our forests special is their lineage:
- Grown from Seed: Every tree we plant is started right here at the Localeaf nursery, grown from locally sourced and nearby seeds.
- Resilient & Native: We are locally rooted, with a learning laboratory here in Aylmer that allows us to observe the resilience and performance of multiple species locally, in a tiny forest setting.
- Community Driven: While we help guide, plan and facilitate the creation of new Tiny Forests here in Aylmer, these are community events, where volunteers, neighbours, teachers, students and multiple generations of community members come together to prepare, plant and continue caring for selected sites, learning together throughout the process.
Let’s Plant One Together
We have access to locally grown young trees, shrubs and forest floor plants, we have the knowledge, experience and capacity.
If you have a schoolyard corner, a park lawn, or a community space that needs a burst of biodiversity, get in touch. We are always looking for new partners to help us grow Aylmer’s canopy, one tiny forest at a time.
