In March 2020, Joel was invited to present to the Yankalilla & District Historical Society on our research into how the landscape of the Fleurieu has changed over the last few centuries. Below is an edited version of the talk. If you’re interested in knowing more, we can also send you some links to interesting historical images from the colonial period. Any errors are our own – let us know if you have any questions or comments.

In 2012, my wife Sophie and I, with our children Asher and Annika purchased Yarnauwi, just outside of Second Valley. Our property is just under 50 acres, running between South Road and the Wirrina golf course, and over the last seven years with the generous support of our friends, neighbours and family we’ve worked to regenerate this patch of the landscape.

Our property is intended to remain at least partly agricultural. We’re not seeking to return it to a prior state of imagined ecological perfection. As we’ve discovered through our research and through our experience of working with the land over the last seven years, too much has changed and is still changing to return what was there before colonisation.

Instead, we’re working to restore its health and function as a landscape, and to build its resilience in a changing climate. I’m neither an historian or a scientist, however we have spent a lot of time contemplating both history and science, and tonight I wanted to share with you some of what my wife Sophie and I have discovered in our process of working to regenerate Yarnauwi.

There’s been so much growth and change at the farm over the last year that we really wanted to share with our team of volunteers and supporters. However, with everyone staying in their postcode this holiday weekend and farm tours suspended for the foreseeable future, we thought we’d put together a little video so you can still enjoy the big skies of the Fleurieu! Take care, and we hope to see you back under the trees soon!

2019 began and ended in fire. In early January, some errant fireworks set off by passers-by landed in one of our front paddocks, burning across a couple of hectares of our property. We were lucky. There was little wind, and it was quickly noticed and contained by our amazing neighbours and the CFS. Meanwhile, in Tasmania, fires ripped through the forests, and by spring and early summer, vast tracts of the east coast and Kangaroo Island were catastrophically aflame once again. While we’ve escaped the drought and bushfires that have gripped so much of the continent, these phenomena have served to focus our goals and aspirations in 2019. It’s been a year of learning as we work towards a more regenerative approach: ultimately building soil and harvesting water and carbon in the landscape.

2019 had the dubious distinction of being Australia’s hottest and driest year on record. It got pretty warm in the shed.

Learning
Our regenerative aspirations have been focused by some outstanding events this year. In June, we attended the Deep Winter Agrarian Gathering in Willunga, drawing together 150 aspiring and established regenerative farmers from around Australia to share skills and ideas. Former CSIRO microbiologist and climate scientist Walter Jehne set the tone with a rousing and inspirational keynote on restoring natural processes through agriculture to cool the climate.

Winter work: erosion control in dispersive soils

Some of the challenges of our landscape regeneration efforts have been both working to restore eroded badlands in some parts of the property, as well as to arrest continuing erosion. To make matters more complex, some sections of the property have “dispersive” subsoil. While the topsoil is relatively stable, when the subsoil becomes saturated it dissolves and begins to move, hollowing out tunnels beneath the surface that ultimately collapse into sinkholes, and eventually gullies. Of course, because it’s all happening underground, tracking or predicting which areas are vulnerable, or already cavernous is tricky.

Over the last seven years, we’ve been gradually working our way around the property installing erosion control structures, based on the work of permaculture-based landscape restoration folk like Craig Sponholtz and Bill Zeedyk. Hailing from the dry southwest of North America, Sponholtz and Zeedyk advocate applying small and slow interventions that use local materials to slow water flows and gradually heal erosion. In the permaculture spirit of viewing problems as solutions, our junk-filled erosion gullies have provided a seemingly inexhaustible supply of demolition rubble, concrete chunks and segments of brick walls that are ideal material for these structures.

This headcut just keeps moving, despite the perennial grasses and good ground cover.

One of the sections that we’ve avoided is a notorious headcut that our DIY soil tests showed us boasted slaking soil that disintegrates when moist and subsoil that was also more saline than other locations around the farm. With saline subsoil, most plants wanted to avoid getting their stabilising roots down. Tree-planting was also fraught, survival rates in the saline subsoil and cracking grey topsoil were low and  the very process of digging a small hole for a seedling can be enough to expose the subsoil so that next time there was a downpour, a sinkhole would open and swallow the seedling, tree guard and all. With the headcut moving about a metre a year and also widening, we thought it was time to get stuck in. At the very least, we’ve discovered that doing something is better than doing nothing and the act of getting in there and digging around allows for more accurate monitoring and effective intervention.

Yarnauwi Treefest 2019

A serial tree-planter manages to synchronise his outfit with the colouring of Eucalyptus occidentalis.

A couple of days before this year’s tree planting, I rang our friend and regular tree-planter Jeremy, and told him that three out of four family members were sick with the flu and we were thinking of cancelling this year’s planting weekend. He didn’t accept that proposal, effectively telling us that tree planting would happen regardless of our involvement, that between his family and another they would take care of catering, rally the volunteers and get the trees in the ground.

It has always been an aspiration of ours that the farm might offer a place for people to be able to develop connection with the landscape through collaboration on land-based projects – “where people and the landscape can restore each other”. I hope that Jeremy’s response, and the support of our friends and community over the last seven years of tree-planting is an indication of this aspiration in development. In this spirit, this year we were also delighted to host regenerative side projects such as Steven Hoepfner’s seed ball regeneration experiment, and provide a waterway for Sue and David Speck’s sedges, and a forever home for Greg Wood’s trees.

Despite a long silence from us, there’s still lots going on at Yarnauwi, not least our ongoing attempt to clean up historic dumping in our erosion gullies. We feel like we’re closing in on the last 30 metres or so of junk to clear and now we’re so close to finishing it can sometimes be difficult maintaining motivation! While most of the material remaining is steel or demolition rubble, both of which we recycle or repurpose, there are still pockets of wonder in the form of various plastic domestic items. Happily, the plantings established in previously cleared areas are now well-established and working to stablise the exposed gully walls as well as restore them as habitat and an ephemeral waterway. We’ll write with more updates soon, but in the meantime, enjoy these treasures from the deep.

Specimen #51: Plastic clown launcher from a “Dandina Sky Dancer”, released in 1995. This particular clown is from the Italian Masque series of the toy. Intact toys from this series in original packaging are available online for a mere US$75.00. (Thank you to Pascelle for the ID, see comments below)

Specimen #52: Wobbling bear in winter attire.

Specimen #53: Battery operated toy train.

Specimen #54: Lightly soiled Boggle Junior console, dating from around 1988. Some cosmetic wear and tear.

Making a floating habitat island

The planted habitat island, ready to launch

Regular readers and supporters of our farm will be familiar with the challenges we’ve faced trying to re-establish native vegetation in the face of large populations of rampaging herbivores. Inspired by an idea from @nature_at_work_ (check them out on Instagram) and folks around the world working to increase urban and rural habitat, we thought we’d construct a floating habitat island.

Once installed in the dam, we hoped the island would function as a seed bank for aquatic plants, a fox-proof roost for waterbirds, and offer filtration through the plant roots as well as aquatic shelter and habitat.

During the summer, our friend Shani, assisted by a team of kids, got to work assembling a frame from some leftover PVC stormwater pipe to act as the float, with a length of shade cloth salvaged from our gully junk to act as a base onto which we could later plant local aquatic plants. The frame was tied to a rock anchor and then launched with great ceremony.

Installation requires a great deal of precision and technical know-how.

In the following months, the island became popular with waterbirds of all types, with ducks often spotted perched on the floating edge, grebes diving underneath and the enclosed centre of the island becoming coated with feathers and bird manure. Continue reading →

Tree-fest 2018: Six years and growing

Volunteers planting at the very first Yarnauwi tree planting extravaganza, 2013

The work continues in 2018 with new plantings amid established trees.

Six years ago we first invited friends and family to come and plant trees at Yarnauwi. They came, dug holes in a windswept paddock, hunched their shoulders against the cold and ate lunch beneath one of the property’s two big old red gums. That first year most of the plants were devoured by kangaroos and deer. Amazingly, our friends and family came back the following year and every year since, with the tree-planting weekend growing into an annual celebration of moist ground and hope for the future.

Yarnauwi: the First Five Years

Towards the end of 2012 we first came to Yarnauwi Farm. The property at that time was a single paddock, carved up with junk-filled erosion gullies and with two regal, remnant red gums smeared up the hillside by the wind. However, set within a grand landscape of rolling hills and a couple of kilometres from the coast, there was something about it that captured our attention and our aspirations.

Five years later, the property is beginning to change. The survivors of annual tree planting are now heading skywards, most of the junk is gone, paddocks have been fenced, some erosion gullies are stabilising, sheep graze, fruit trees peek from the tops of tree guards and rain thunders on a shed roof. The last five years have brought with them an almost vertical learning curve, challenge, plenty of failures and the indescribable satisfaction of seeing seedlings become trees become woodland.

We’ve tried documenting this process online here at yarnauwi.com, but to celebrate this milestone we’ve also produced a limited edition book curating photos, illustrations and writings from the last five years.

This slideshow requires JavaScript.

Yarnauwi: The First Five Years is divided into sections on the history of the property, trees and tree planting, creek restoration and erosion management, treasures extracted from the junk heaps, property planning, “obtaining a yield” and landscape change through the Fleurieu seasons. Each section is copiously illustrated with photographs and drawings and hopefully provides inspiration to others who are seeking to regenerate their own landscape or who have a connection with the spectacular landscape of the Fleurieu Coast. A number of sections contain “before-and-after” photographs of locations around the farm showing the impact of tree planting and low-tech erosion management strategies, predictably however, with a few decent summer downpours the changes were even more dramatic just a month or two after taking the final photographs!

It’s available for purchase now from our Etsy shop and we’ll also have a few copies available, together with sheepskins and farm- and Fleurieu-inspired artworks at the Second Valley Market from 10.00am-3.00pm on Saturday 27 January 2018.

New poster: Imagining Yarnauwi before colonisation

Over the last few years, we’ve spent a great deal of time learning about the landscape of Yarnauwi, and the broader southwestern Fleurieu Peninsula. This has been essential for us in helping us to understand how the landscape works, and therefore how we can best work to ensure its health and function. We’re inspired by a statement from the 2015 Greenhorns New Farmer’s Almanac, where Connor Stedman writes, “Farms, forests, and grasslands can store and regenerate natural capital again, rebuilding the ecological fabric that is the ultimate source of our prosperity and survival. But to know how to undertake that stewardship, it’s not enough to know the land as it is now. We need to dig below the recent surface and go deeper – find the older ecological and cultural stories of a place. It’s the wildlands that hold these stories, and it’s these lands that will return them to us if we know where to look and how to listen. An agrarian economy needs to tend, restore and engage in a deep relationship with the wild as well as the planted field.”

In this spirit, in this poster we’ve tried to imagine and illustrate the landscape of Yarnauwi and the surrounding area as it may’ve appeared before colonisation. It summarises our reading and research, as well as our experiences exploring more intact local landscapes. It’s a work of imagination, it’s definitely not to scale, but we hope it helps communicate some of the complexity of a functioning landscape and the interactions of the Kaurna in maintaining its function and ecological health over millennia. Then, as now, the southwestern Fleurieu was a cultural landscape, maintained through intentional management practices. This poster is also an effort to acknowledge our own place in the long history of this landscape. Continue reading →
