Community raises $20,000 for Downer micro-forest

The Climate Factory and the Downer ParkCare group raised $20,000 to build a pilot micro-forest at the Cole St park in Downer. Over 180 individuals and businesses supported this initiative.

Edwina Robinson, Landscape Architect and Founder of The Climate Factory says, “planting trees is one of the simplest things we can do to address hotter, drier climates. Trees cool the environment, provide habitat, absorb carbon and improve property values.”

The $20,000 raised will pay for community engagement, development of a Landscape Sketch Plan, soil improvement, 1500 climate-ready native trees, shrubs and groundcovers and a water cart to keep plants watered during the establishment phase. The Downer ParkCare group will maintain the space and will have a say about other features they’d like to see in the park.

Robinson formed the social enterprise, The Climate Factory, in 2019 after Canberra experienced its hottest summer on record. She says, “Bureau of Meteorology records show January 2019 temperatures for Canberra were 6 degrees above average. I knew I needed to do something. So whenever I think, why the hell am I doing this, I remind myself I’m doing this for my adult children and my unborn grand-children”.

Robinson says she wouldn’t have had the confidence to launch her social enterprise and Crowd Funding campaign without the support of the Mill House GRIST program.

The Climate Factory will work with tree and native plant experts to create a climate-ready plant list for a public space. They will choose plants with low flammability and that can cope with hotter, drier weather.

Native plant nurseries will start growing plants before the end of the year with the first planting day scheduled for April 2020. Robinson says “hopefully it will be a mild Autumn and plants will get a great start”. Supporters who pledged $25 or more will be invited to the first planting day in 2020.

In October 2019, Robinson and Lachlan Richardson, Bluebell 2509 installed a micro-forest of 300 native plants across the road from the Cole St Park. They are looking forward to working with the Downer community to watch both micro-forests grow.

The Climate Factory is looking for partners and sponsors to build a micro-forest in a school in one of Canberra’s urban hot spots in 2020. Robinson says, “The Climate Factory will use land surface temperature maps created by CSIRO to help work out which Canberra schools need micro-forests the most. We will work with students and teachers so they can learn about the values of forests and together design and build a micro-forest and show them how to maintain it.”

Service One, a 100% community owned bank, kicked off the fundraising with $5000. The other official sponsors are:

Gold Sponsors $1000

The Silver Birch is dead

In 2010, I bought a Canberra fixer-upper with no garden to speak of. The front garden boasted two non-fragrant roses, an oleander (despised from my childhood) and a Liquidamber street tree.

As a young Landscape Architect student I was besotted by Edna Walling. Acclaimed as Australia’s first landscape architect, Walling was an unconventional woman. She ran a landscape design and construction business from the 1920s , built her own cottage and created an English style housing development in Victoria, named ‘Bickleigh Vale’.

The first essay I penned at the University of Canberra was about Miss Walling’s design style. English born, she determined the location of Silver Birches by scattering potatoes on the ground.

 With a new garden to design and plant on a budget, I decided I wanted a grove of white trunked Silver Birch (Betula pendula). Underneath I would grow rosemary and Grevillea. Note: the rosemary (tough bugger that it is, thrived) but the Grevillea ‘Deua Flame’ died one by one.

Birches have a reputation for thirst – but the Millenium Drought was over and I knew I could gravity feed water from an upstairs bathroom, if needed.

That Autumn, after removing the roses and oleander and the patchy grass, I planted nine $20 birches into compost enriched soil. I wasn’t as flamboyant as my hero, Walling, the birches were planted in evenly spaced trios.

Three years and a few wet seasons later, the Birches thrived. Lying in my upstairs bedroom I could glimpse their canopies and marvel as the Rosellas performed acrobatic feeding acts dangling from drooping branches.

But success was short lived.

Those nestled close to the house or large shrubs thrived. However, the Birches abutting the western side of the block with its hard, hot drivewayof concrete and bitumen and nothing to buffer blasting summer winds, fared poorly. Their trunks were only half the diameter of the happy ones.

In the back garden, I planted three tubestock of Snow Gum (Eucalyptus pauciflora). They grew quickly to about four metres high, and after a couple of very dry summers I was left with one survivor. Snow Gums suffered a similar fate at the nearby Banksia St, O’Connor wetland where planting commenced in 2010.  

Records from the Bureau of Meteorology show that Canberra’s summer of 2018-2019 was the hottest on record. The Birches branches browned.

This year, nine years after planting, I removed three of them, and sold the house.

Temperatures in Australia have risen by at least 1 degrees celcius since 1910. And we know Canberra’s future will be hotter and drier with more extreme events, including heatwaves and intense rainfall.

Temperatures will not only impact the types of trees we can grow in Canberra in the future but our ability to stay fit and well.

Increasingly evidence shows high temperatures result in increases in violence and mental health presentations. And who wants to exercise when it’s extremely hot? This will no doubt impact obesity levels and associated preventable diseases, like diabetes.

Unfortunately we’ve lost a significant number of trees in Canberra over the past few years and it’s vital to boost our tree canopy with climate-ready species. Note: the ACT Government committed in the 2019 budget to plant 17,000 trees over the next four years.

As I cycled round Canberra in Autumn 2019, I noticed one stellar deciduous tree – the Crepe Myrtle (Lagerstroemia) with its motley bark, multi-trunked stems and vibrant flowers was a stand-out.

Another, under-celebrated tree, the Kurrajong (Brachyciton) has proven to be a great performer. At Banksia St wetland, young plants were attacked by cockatoos (the vandals of the bird world). Those that survived are robust and beautiful.

Leaves of the Kurrajong, at Banksia St, O’Connor wetland. The wetland was constructed by the ACT Government in 2009 and the surrounds planted by the community from 2010.

Creating climate-ready public spaces and gardens will help us thrive in a hotter, drier future. The ANU has been working with the ACT Government to develop a list of trees suitable for public spaces for changing conditions and CSIRO has developed heat maps to identify areas at most risk of heat exposure with vulnerable populations. There are sections of Belconnen, Gungahlin, Molonglo, Tuggeranong, Weston Creek and Woden where communities are at significant risk. No surprises, that if you live near Lake Burley Griffin you will probably be ok during heatwaves.

The CSIRO report recommends planting vegetation and forests in our public spaces, streets and parks as one of the main ways to mitigate future heat. Plants have a more significant cooling effect if we can find ways to irrigate them, using water harvesting.

As a result of the hottest, summer on record I knew I needed to act. So The Climate Factory, was borne.

The Climate Factory is a social enterprise, that designs and builds micro-forests, to ensure we thrive physically and mentally in a hotter, drier future.

  1. Hi Edwina … my late lecturer in Landscape Architecture when it was still the CCAE, Glen Wilson, was a disciple of Edna Walling and spoke often about her and her work. I now live in Bundanoon, slightly warmer than Canberra, in a house with a large garden. I’ve noted how poorly the Silver Birches are performing here. Planted by the previous owner at least 20 years ago they attained a reasonable height but have now deteriorated considerably. I’ve removed one but three others need to be replaced. Two Weeping Silver Birches are, however, still doing quite well. Recently, I found in the Bundanoon Garden Club library a book on Edna Walling which contains images of her classic watercolour plans. The club, sometimes said to be the largest garden club in the country, will celebrate its 50 year anniversary next year with year-long activities.

    1. Hi Jim, Thanks for sharing your story. I’d be interested to hear what trees are doing well. We are finding trees like Japanese Maple get their leaves fried by the hot dry winds. I also have a garden at Moruya, near the NSW south coast, Japanese Maples thrive here.
