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.

“You’re just so far away”: A tale of a farm shed

The Yarnauwi skyline is changing: some is grown, some is constructed.

A ‘Grand Design’ it isn’t, but the Yarnauwi farm shed has seen enough delays to make even Kevin McCloud blush. After 14 months, our simple 4-bay equipment shed is finally done. Ordered in January 2016, with the shed company suggesting an initial completion date of June 2016, this modest structure was beset with delays ranging in scale from an apocalyptic winter through to urban tradies that couldn’t quite stomach the prospect of venturing beyond suburbia.

Done!

One of our hoggets, sizing up the new facilities.

We’re great fans of temporary. Not aiming for permanence tends to mean that ideas can be trialled inexpensively, can be easily changed and that learning from failure can be quick and low-impact. In that spirit, as we develop the sheep enterprise of the farm, we’ve tried to keep things low-key. For yards, we use locally-made portable panels, but when working closely with sheep, we found the mesh sides problematic due to the ease with which horns or feet can become entangled. In more established circumstances, yards would have a working race for such a purpose, but the cost of a manufactured race can be steep. It was time to get out the tools and make our own.

The ‘new’ working race in position, with sheep, also in position. As a further refinement, we need to attach bracing to the far end to help it stand up to the inevitable knocks and bumps.

A moveable sheep shelter: the sequel

With recent temperatures climbing into the 40s (about 107 degrees Fahrenheit), and tree-induced shade still a few years away, we’ve constructed another moveable sheep shelter to ensure our sheep and alpacas have a cooler place to recline on the most hostile of days.

IMG_5444

Employing the off-grid carpentry prowess of Jeremy and Pete, we knocked up the second shelter to the same rough plan as the original: salvaged hardwood for a sled base, allowing it to be dragged from pasture to pasture, fallen redgum for uprights, and tin reclaimed from the gullies for the roof. The previous life of the tin means that a hole is already cut for the installation of a pot-belly stove, should the sheep find one that fits their budget. This sheep shelter also includes a perch, should passing birds need a break while searching for a tree. Continue reading →

The moveable sheep shelter in fresh pasture.

While the name Trees, Bees and Cheese might suggest otherwise, one thing we’re short on is trees. So with the arrival of sheep, and now lambs, we’ve tried to get in before summer with a sheep shade-shelter. With our soon-to-be-complete subdivision of the property into smaller paddocks, we thought we’d build a moveable shelter that would allow us to rotate it from paddock to paddock with the flock, rather than building seven or eight smaller structures.

Stile Design #1, the crossed tread option.

Fences are amazing things. They totally reshape the way you think about a landscape by cutting it into smaller, yet still expansive, rooms. They alter the movement patterns of humans and other animals and we’ve very quickly discovered the bits where, far from any gate, we’re regularly having to launch ourselves between strands of high-tensile barbed wire. With a bit of research, we came up with a couple of simple designs for stiles allowing easy pedestrian access at high-traffic points. Continue reading →

Uses for tyres: livestock shelters

Pete, lifter of heavy things, Employee of the Month

Earlier in the year, our friend Pete decided that the time was right to haul the last clump of tyres from Zephyr Creek. It was about 8 o’clock at night, and after a cursory glance, he predicted that there “couldn’t be more than 30 or 40 in there.” Almost 200 tyres later, Pete had earnt his “Employee of the Month” status, and with assistance from Will, had built a respectable tyre mound on the edge of the creek. Thanks. I think.

The patch buried under tyres is slated for revegetation this winter, so we couldn’t leave the tyres there indefinitely, nor could we afford their disposal fees, nor could we find any earthship or go-kart track builders interested in taking them off our hands. So after pondering them for a while, we settled on Option E: using them to construct sheep shelters. Continue reading →

Pipe Dreams: How to set up a watering system for stock

‘Pipe Dream’: useful for passing time in the late 1980s, not that useful for planning livestock systems.

One of our key milestones in the development of the property this year was the establishment of a watering system for livestock. Having a watering system supports our fencing of the farm dam and waterways for habitat regeneration and also allows us to more intensively manage the movement and impact of livestock through rotational grazing. While we’re still the furthest thing from expert, with the advice and support of our neighbours, we managed to knock together a watering system that works. In researching and developing our own plans, we found an absence of basic information on setting up stock systems, so the ideas below are a few of the things we learnt or found useful in planning a system for our own context and landscape. They are just one perspective in informing your own planning, and shouldn’t be read as an endorsement of any particular way of doing things.

Nature abhors a vacuum

Following the evacuation of its previous residents, the bee-house has not remained vacant for long. Offering waterside views and passive solar design, resident roos have recently been spotted conducting an open inspection of this prime real estate.

The First Phase of Fencing: Marking Zone 5

The gate into the top end of the northern revegetation area

While our impact on this landscape has been pretty minimal so far, with the completion of our first phase of fencing, we’ve begun more major infrastructure works. We’ve started by fencing off two big chunks of ground encircling the erosion gullies, surrounding them with a roughly 20-metre buffer zone for future woodland regeneration.

IMG_3231

Neat knots

In a permaculture sense, these patches of ground will be our Zone 5, our minimal-management ‘wilderness’ zones, designed for habitat and ecosystem services such as erosion and salinity control and water filtration. Abutting our western boundary they form a link with the creeks and swamps that feed the Congeratinga River. With these zones now marked onto the landscape we can plan outwards towards zones of increasing management intensity. Continue reading →

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.
