Microforest Creation

Why create a microforest at Hancock St Park?

 This project has received funding support from the Queensland Government’s Community Sustainability Action grant program and an environment grant from Toowoomba Regional Council.

Hancock St Park is an endangered ecosystem 
(classification 12.5.6: https://apps.des.qld.gov.au/regional-ecosystems/details/?re=12.5.6). 

The park is a tiny spec of the original natural world, of Rangeville Toowoomba. It is an environment rich in life, despite its small size. The plants of Hancock St Park are native to this area, and provide habitat for native animals, birds and insects. Close by Hancock St Park is another parcel of land which houses St Bart’s Church. 

This land also supports the same endangered ecosystem. Bridging the gap between Hancock St Park and the St Bart’s Church land is a piece of land, about the size of a house block which is currently mown grass. By replanting this grassy piece of land with the same plant species which are found in Hancock St Park and in the St Bart’s Church land we will add to the viability of this ecosystem and create a wildlife corridor linking the two.

What is a microforest?

The mini forest (microforest, pocket forest) concept was developed by Professor Akira Miyawaki, a botanist, as he sought to recover and recreate plantings of original ecosystems found in different parts of Japan. Over the 40 years of his work 500 mini forests were created in Japan. His ideas spread to Europe, the Americas, the Middle East, the Indian subcontinent and to Australia. Microforests have been recognised as part of a worldwide effort to regreen our planet, to provide habitat for endangered species, to moderate the climate, and provide carbon storage. Please see our links to find out more about microforests in Australia and around the world.


How is the Hancock St Park Microforest being created?

In 2022, Friends of Escarpment Parks (FEP) submitted a grant proposal to the Queensland Department of Environment and Science, which was successful. This grant supports the purchase of plants, watering equipment and plant guards. FEP also submitted a second grant proposal to the Toowoomba Regional Council. This grant supports the cost of site preparation.

Crow’s Nest Community Nursery has undertaken the task of propagating the plants for the microforest. Only plant species which are naturally found in Hancock St Park are being grown, and many are being propagated from seeds and cuttings collected in the park. There will be a few trees, many small trees, understorey plants, herbaceous plants, grasses and creepers. Please see the plant list. The microforest site which is the size of a tennis court (600 m2)   will be planted in three stages, each 200m2.


Collecting Cuttings for Propagation

Acacia maidenii or Maidens Wattle grown at Crows Nest Nursery for the project. To germinate acacia seeds  boiling water is poured on to them and they are allowed to soak for a few days. The heat simulates the conditions they need to sprout. Below Acacia melanoxlyn or Blackwood flowered in the park in January. (Photos M. Henderson)

The Timeline for creating the Microforest

·       November 2022 – March 2023 – Crows Nest Nursery grows plants for the project. Many of the seeds and cuttings have been collected from Hancock St Park

·       January and February 2023 – Spray the grass on the microforest site – FEP

·       March 2023– Cultivate the soil and incorporate organic matter – landscape contractor

·       April 1 2023 – First planting – Volunteers from FEP and local community

·       April 2 2023 – Mulch the first planting area and the overall site - Volunteers from FEP and local community

·       Undertake watering and weeding – April 1 2023 onwards - Volunteers from FEP and local community

·       Spring 2023 – Second planting - Volunteers from FEP and local community

·       Autumn 2024 – Third planting - Volunteers from FEP and local community

Preparation of the site commenced at the beginning of the month.

In preparation for the planting, we need to remove the grass on this site. This has been done by a herbicide spray undertaken by a Friends of the Escarpment Parks volunteer. It is estimated that the forest which will replace the grass will store 30 times more  carbon than the grass can. And once established (approximately three years) will require minimal maintenance.


March 2023

Machinery was used to cultivate the soil to a depth of 30cm and a layer of 10cm of compost was incorporated into the soil. The process aims to simulate the ground level of a forest ecosystem. The soil was then evenly raked over in preparation for planting. 
Stage 1 planting will take place on 1 April 2023. A list of the species to be planted is available under the "Plants" page on this blog. A full description of the plants can be obtained by emailing: secretaryFEP@gmail.com

600 Plants Ready for Planting on April 1 2023

Planting Day - a huge success!

Over 60 people, including Friends of the Escarpment Park, neighbours of the park and community members came to assist with planting. It was heartening to see several families with young children among the participants. People signed on, were given a safety briefing following by instruction in the process -  preparation of the hole, planting, watering, mulching and guarding.

July 2023 - Care and Maintenance

During the last four months volunteers have continued with regular watering, weeding and mulching. The plants in the microforest have grown well and some are now in flower, despite the cooler weather. 

The table below shows the rate of growth of several species since planting in April.
Some are growing more quickly than others. The groundcovers like Commelina and Einadia in particular are spreading extremely quickly and it may be necessary to cut some of these back to stop them from smothering nearby plants.

Spring Planting

The next stage of planting will take place on Saturday 14 October from
8.00AM to 12.00noon. All welcome!

Spring Planting - Stage Two

Fifty people attended the planting day. Stage Two of the microforest has now been planted, bringing the plant total of stages one and two to just under 1000 plants.  All of these plants are found naturally growing in Hancock St Park. Plants were grown for us by Crows Nest Community Nursery, and we also obtained some from Paten Park Nursery. 

Ongoing care  for about two years is required to keep the plants alive. After this time, the forest should be self-sustaining. Requirements are simple: watering and weeding, and the mulch may need topping up. If you would like to participate on either an occasional or regular basis, please contact the Secretary: secretaryfep@gmail.com. It is a pleasant and rewarding task to weed and look after the plants in this lovely location. 

The philosophy of creating a microforest is to reestablish a plant community that was originally growing in a location, but which has been cleared. This provides habitat for wildlife and reintroduces biodiversity. The Hancock St Park microforest is extending the endangered ecosystem of Hancock St Park. Note: The Hancock St Park ecosystem is classified as 12.5.6. It is a mid dense open forest usually found on deep red soils at higher altitudes. It provides a suitable koala habitat. It is estimated that preclearing 36,000 hectares of this ecosystem was found in Queensland, whereas in 2019 we had 8000 hectares remaining. This is a loss of 78%. 


Carbon storage and temperature modification (cooling) are also important outcomes of this process. There is  a specific method which is used in microforest creation, and this is based on the research and practical work of the founder of this approach, Akira Miyawaki. His approach has been adopted throughout the world. Note: https://www.gdrc.org/u-gov/rewild/rewild-08.html

Microforests can also be created in home gardens and we can draw from this approach to create wildlife gardens by selecting a range of garden plants which are local to our area to provide habitat for wildlife. 

 Stage Three planting will take place in  Autumn 2024.

Hancock Street Park Microforest Autumn Planting 2024

On Saturday 23 March 2024 we completed the Hancock St Park microforest plantings. 520 plants were planted, plant guarded, watered and mulched on the day by 48 community and FEP volunteers. The day started with safety talks, planting and plant guarding demonstrations. Thanks very much to Greg Lukes and Shirley Dunsdon. At 9am Tiffany Gessler asked us all to be mindful of the moment, tune in to our wonderful surroundings while she shared with us an Acknowledgement of Country. Thanks very much Tiffany. You have provided a beautiful Acknowledgement of Country for all three of our plantings. Thanks to all our volunteers on the day. We had a great time and had downed tools by 12pm.

Acknowledgement of country

Growth of microforest stages one (planted in April 2023) and two (planted in October 2023) have been beyond expectation, with stage one plants now towering above us and forming a dense mini bushland. This success can be attributed to the careful implementation of the Miyawaki miniforest method, good soil, rain and care from FEP volunteers. All plants used are those found growing naturally in Hancock Street Park, an endangered ecosystem (classification 12.5.6). This revegetation project turned a 600m2 piece of grassed land into a forest habitat.  Thank you to everyone who has been involved. We hope to inspire more microforest creators.
