The Climate Factory has partnered with the Downer ParkCare group to launch a CrowdFunding campaign to raise at least $20,000 to build a micro-forest at the Coles St neighbourhood park in Downer.
Planting trees is one of the simplest things we can do to address hotter, drier climates.
Edwina Robinson, Landscape Architect and Founder of The Climate Factory says trees cool the environment, provide habitat, absorb carbon and improve property values.
Service One, a 100% community owned bank, has kicked off The Climate Factory’s fundraising target with $5000.
Robinson says, ‘if we are successful in raising the $20,000 this will pay for a Master Plan for the Coles St, Downer park; 1500 native trees, shrubs and groundcovers; soil improvement and a water cart.’
The Climate Factory is a newly formed social enterprise responding to the impact of climate change in Canberra. Edwina says ‘after experiencing the hottest Canberra summer on record, with January 2019 temperatures 6 degrees above average, I knew I needed to do something. I’m doing this for my adult children and my unborn grand-children’.
The Climate Factory want to empower people in suburbs disdadvantaged by the Urban Heat Island effect create micro-forests in public parks and schools.
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 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.
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.
