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 →

Time and change: revegetation inspiration

Impatient as we are, we’ve become slightly obsessive about “before-and-after” photos in an effort to stay inspired about the possibilities for landscape transformation. About 15 minutes down the road from Yarnauwi, our friends David and Gillian have been gradually revegetating a former grazing property in the hills above Cape Jervis. Perhaps because of its steepness, the property has retained a good number of big old pink gums, together with the occasional ancient sheoak, offering the beginnings of a canopy for regeneration. Seven years ago we helped out with one of their first planting weekends, and I recently unearthed some photos taken at that time. With David, we recently walked around the property to admire the last seven years of growth.

David and Gillian have been philosophical about kangaroo grazing, with plants getting no more protection than korflute guards. Some plants have been repeatedly mowed down, reaching no higher than the tree guard after seven years, while others have finally stretched above mouth height and are now heading skywards. David notes that no plants were about adult should height for the first five years – something we can relate to at Yarnauwi. Continue reading →

“Trees are the poems the earth writes upon the sky” said Kahlil Gibran. Pete, Shani and Sophie prepare to plant.

This year is our fifth on Yarnauwi, and this June saw our fifth annual tree-planting extravaganza. Over the last five years, our amazing community of tree planters and supporters have planted 5000 trees and other plants on Yarnauwi as we work to restore woodland, stabilise and repair erosion and plant trees for future timber, forage and food. Following the last four years of observation and experimentation, in 2017 our main focus was planting carefully selected species into some of the more challenging areas of the property. Each year we’ve propagated and planted trees sourced from both Trees for Life and our own seed collection. In addition to their generous labour and time, we’re honoured that Yarnauwi regulars Richard and Marg have now immortalised the annual tree-planting tradition in a musical saga, published below and sung to the tune of Loudon Wainwright’s The Swimming Song. The lyricists also pre-emptively apologise for any character assassination contained within.

Putting in soil-stabilising groundcovers around the shed.

A week or two following the tree-planting extravaganza, we were delighted to host the Permaculture Association of South Australia for a walking tour and lunch, sharing our property planning process and how we’ve approached the landscape restoration through a permaculture lens – of which these plantings are a central element. Thank you to Tree Team 2017: Anthony, Pete, Shani, Arlo, Freya, Jeremy, Claire, Innis, Sal, Mary, Branny, Richard, Marg, Nat, Jess, Oliver, Gillian, David, Geoff and Andrew.

One of the electives at this year’s tree-planting fiesta was making plaster casts of animal tracks. Here we have a collection of fox tracks from the dam’s edge.

In birthday cards I often wish the recipient a coming year of “the right kind of challenge”, optimistically suggesting it will herald positive growth and empowerment through problem-solving and negotiation. This year, I got a taste of my own medicine, with a winter of biblical proportions just the beginning of the challenges.

November marks four years since we began the Yarnauwi project. Four years of attempting to regenerate the property to our optimistic standards on the weekends, of packing and unpacking the car, of ferrying and entertaining one, then two, small children, of revegetating, managing erosion, managing pasture, managing water, managing livestock, managing weeds and managing the legacy of past land managers. These are all admirable, ambitious intentions, and what we’ve achieved has only been possible through the support and enthusiasm of our community of neighbours, friends and family.

The Wet Season 2016

The first big storm saw the dam fill and rivers broaden to ten times their normal size for an afternoon. A neighbour’s creek crossing dissolved in the flow, the rock and rubble broadcast along the river bottom. The second big storm saw our rainwater tank, still awaiting a shed to fill it, lifted vertically from its nest of stardroppers, vaulting a tractor and four or five fences before being swept off in the swollen waters of the Anacotilla River, carried across two properties and wedged under a red gum. The third storm came with days of warnings, threats of winds over 120km/h and rainfall to rival all of the previous deluges. It left all of South Australia without electricity, the farm a sucking, gurgling swamp, and me walking home through a darkened, scrambling city.

Mist in the valleys

It’s been a demanding few months on the farm. The persistent moisture has made the ground unworkable, most of the farm inaccessible except on foot and the weather generally hostile to both our motivation and ability to do anything useful. The vast quantities of rain we’ve received however, have meant that moisture has permeated deep into the subsoil, so we console ourselves with the hope that as the weather warms, our tree plantings (including those from earlier this winter) will rocket skywards.

Farming with young children

IMG_8221One of our motivations for seeking land beyond the city was the hope that it would support our children to develop a deep connection with a particular patch of ground. Of course, in imagination, it’s all pretty easy: self-directed kids building cubbies in the golden light of late afternoon, climbing trees and constructing dams. In truth, it sometimes feels like masochism.

There are so many things we could have done (and are now trying to do), that would have made the first years of working with Yarnauwi easier. Our restorative ambitions meant that we chose a piece of land that, while superbly located, is highly exposed and has been much abused over the last almost-two centuries. It brings with it endless challenge, and the need for constant monitoring and intervention. The weather sometimes feels defined by the kind of driving winds that take water tanks for excursions around the farm. There’s always work to be done, and sometimes it feels like you’re working without progress, in an environment that can be hostile to weather-beaten, outdoorsy adults, let alone toddlers.

Matching trees to tricky spots

Eucalyptus occidentalis, a hardy, salinity and waterlogging tolerant timber and bee forage WA species, putting on new growth despite a dry year.

For the first couple of years of tree planting, we adopted a pretty haphazard approach, planting a bit of everything everywhere, and waiting to see what would stick. It took only a couple of months to highlight which areas offered the conditions for revegetation at a respectable pace, and which did not. Some patches only appeared to support certain species, others seemed to support nothing at all. The challenge has been to work out why. For enthusiastic amateurs like us, the working out comes through plenty of observation, plenty of reading and plenty of research.

IMG_7870

One persistently hostile area of the farm offers saline, slaking, seasonally waterlogged clay with tunneling and cracks you could lose a child down.

For some areas on our farm, vegetation is a valuable indicator, plants like sea barley grass (Hordeum marinum) suggests mild salinity, and, in our case, seasonal waterlogging. In others, aspect and soil type present challenges. Three years of tree planting and walks through local bushland have also given us a sense of which local species might suit which locations. We keep trying new configurations in the same places, and also try to mimic the natural process of succession by planting hardy pioneers first, then waiting for them to establish shelter and canopy before adding others. As the balance of the landscape has changed through clearing, cultivation and the associated effects of erosion, shifting water tables and changes in nutrients and soil biology, many of the species that may have dominated a couple of centuries ago no longer tolerate certain areas of the block. Likewise, some areas that may have been conducive to vegetation when woodland was already present, once cleared, they seem to be hostile to its re-establishment: for example, a north-facing corridor of grey, cracking clay that has resisted our affections for two years now.

Reforesting the Fleurieu, one tree(guard) at a time.

Over the June long weekend, once again our loyal crew of tree-planters descended on Yarnauwi for the fourth year of tree planting. This year we planted 600 plants, local species associated with pink and red gum woodlands.

The 2016 Crew

After 3 years of planting, many patches of seedlings are now well established, and on rainfall only they’re slowly growing into the landscape. Our mission for this year was to fill in some unplanted spaces, trace windbreaks and corridors between islands of vegetation, replant tricky spots with specially selected vegetation and to expand some of our successful woodlots. Spots that we cleared junk from earlier in the year were planted out, and areas of erosion control will also be planted with sedges and reeds this season. Continue reading →

Blue gum (Eucalyptus leucoxylon) seedlings ready for planting.

Before Yarnauwi, we never really appreciated winter. Now, through the long dry season, we find ourselves yearning for a chill edge to the wind, the moisture in the grass, and skies of dark clouds. We’ve tried to plan our year to mimic the lives of so many of the organisms that occupy our landscape: in the hot, dry times, we go into maintenance mode, watching and waiting for the first rains before we spring into action again. With the greening of the landscape, it’s all on: tree-planting has begun, shed sites are levelled, the grass grows. In winter, the kangaroos converge in clans numbering hundreds, displaced from the pasture, they lounge among the seedlings in the reveg areas while we look on nervously.

We’re now three years into the Yarnauwi project. With all of our major water and fencing infrastructure in place, 2015 was a year of consolidating and refining our planting and grazing systems, and continuing to restore habitat while also developing income streams. Once again, we thank you for your support this year, whether that’s been planting trees, purchasing meat, hauling junk, offering advice or just being generally encouraging! We feel enormously privileged to have such a supportive community of family, friends and neighbours contributing to the restoration and development of this patch of ground. Continue reading →
