Getting excited about fungi on a wet day at Hindmarsh Falls, Fleurieu Peninsula.

In the last year or so we’ve really begun to appreciate the importance of fungi in a living landscape. The fungi (toadstools, mushrooms and so on) we see pop up after rain are the fruiting bodies of sometimes vast underground fungal networks. Some of these fungi form relationships with plant roots that are often mutually beneficial and enhance the plant’s ability to access nutrients and moisture. The Australian National Botanic Gardens suggest that some 80-90% of Australian plants form or benefit from mycorrhizal networks (fungal associations), and may derive up to 30% of their food through this symbiotic relationship.

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.

On a balmy autumn afternoon, we celebrated the new shed with sixty of Yarnauwi Farm’s friends and supporters. Following a tour of the farm, we settled into a shared dinner and drinks by the campfire.

To mark the occasion we also produced a self-guided tour map of important developments and points of interest on the property, hard copies of which were gifted to our guests to be stuck on fridges and toilet doors.

The changes that have occurred at Yarnauwi over the last four-and-a-half-years have only been possible through the encouragement, support and labour of our community of friends, neighbours and family. We hope that this celebration went some way towards expressing how grateful we are.

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.

Triplets wait patiently for their mother’s attention again.

The 2016 lambing season has begun at Yarnauwi, with seven lambs dropping so far. One set of triplets, two lots of twins (with three survivors) and our first, puppy-like Damara lamb.

IMG_8382

Damara x Dorper lambs. You may have noticed we also have soursobs.

It’s also our first season experimenting with Manchego the Damara ram. Our initial flock were Wiltshire horns, a British breed that we found were more selective than we would’ve liked in their grazing habits, and sensitive to the exposure of our blistering summers. A few of their lambs were part Dorper, and in the culture of the flock, they’ve mimicked the habits of the Wiltshire Horn matriarchs.  Continue reading →

Winter and the One Rock Dams: erosion control after the rain

Rain, and a full dam.

By late July this year we’ve already exceeded our entire rainfall for 2015, and for now, the rain shows no signs of abating. This is fantastic news for our revegetation efforts, and our dam is now almost full for the first time in two years. With heavy rains – we managed to top 100mm (4 inches) in a single day – it’s also a chance to test the effectiveness of the erosion control strategies we’ve employed.

With significant erosion in some key areas of the property, we’ve worked to adapt erosion control strategies such as those practised by Bill Zeedyk and Craig Sponholtz (see April’s Waterway Restoration workshop/working bee and our Resources page for more information). In particular, we’ve constructed Zuni bowls, for arresting headcuts, and One Rock Dams, to slow water flow, catch sediment and gradually lift the floor of erosion gullies. After the recent deluge, we toured the works to see how we went. The Zuni bowls have had mixed success: those in relative stable locations have been effective, those in dispersive soils have been unpredictable. The One Rock Dams (ORDs) have been generally successful, if swamped by sediment!

The impact of 100mm of rain in one day is significant: exposed areas lose significant amounts of soil (some areas of gully floor had almost 30cm of freshly deposited sediment), and areas of dispersive soil go berserk, collapsing in all directions. For some of these areas, we’re continually seeking further advice, but for those we can manage, we monitor and tweak over time, and try to “let the water do the work” in healing the landscape.

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.

From where we'd rather be...actually there's nowhere we'd rather be! Big thumbs up for the kids' new hammock under the old gums. So glad to finally be here at last! Happy 2023 all 🌿
First fig of the season. A monster Black Genoa, organically grown in our little windswept orchard.
As proof of the recent confusing weather patterns, these Amanita mushrooms came up a few days ago! We've never seen mushrooms here in November, they're usually all finished by August, and we've never seen this species or anything like it here before! Amanitas are mycorrhizal (they form a partnership with a tree/plant to help feed and nourish it in exchange for sugars) and these ones were growing only 1m or so from a Eucalypt we planted about 7 years ago which has always grown really well. I just wonder if this species has been there all along, waiting for perfect conditions of 45mm in one day in Nov to be able to fruit! And now it can reproduce and spread to other parts of the farm. It makes me wonder what else is out there ready to take advantage of crazy climactic conditions!
As long time admirers of @thegreenhorns we're thrilled that Joel's comic about weeds will be published in Vol. VI of "The New Farmer's Almanac". It all releases this January and pre-orders are available now through @chelseagreenbooks
Frog spawn! 🐸 We've never seen this before at Yarnauwi but with the best rains in years our dam is filling up, the air is full of the calls of the Spotted Grass Frog and the Common Froglet, and we seem to be providing enough grassy water habitat for these eggs to be laid with enough shelter for them to grow into the little black tadpoles you can see inside! Lying next to the dam listening to frog calls definitely takes us to our happy place and makes it all so very worthwhile 💚
2022 marks a decade since we started working to regenerate Yarnauwi. To celebrate Joel's been working on a little comic to acknowledge all the amazing folks in our community near and far who have supported us and this place over the last 10 years. Here's a sample, but the whole thing is on our blog - follow the link in our bio!
Thanks to everyone who came joined us on our farm tour as part of @historyfestival and @heritagefleurieucoastfestival - we really appreciate your interest and enthusiasm!
We're honoured to have this story pop up on @abcnews_au sharing some of the work we've been doing to regenerate our patch. Our deepest thanks to all the friends, neighbours and family who have helped transform the property over the last decade!
It's been a good year in our little orchard, with plenty of ripe figs for us - and others! Here's one we found, positioned just like this on top of a fence post. I'm looking for a raven with fig juice running down its chin.
