1950-ltwdtw-i

Weirdly, one of the elements we found appealing about our property was the erosion. In a fit of masochistic optimism, we were excited by the prospect of working to restore a degraded landscape to a level of ecological function, of seeing gully walls stabilised with plants and creeklines resounding with a froggy chorus. As we’ve explored the best strategies for managing and restoring these sections of the property, the advice we’ve received has often tended towards paying someone to think about it and do the work for us, purchasing expensive, industrially produced tools and materials, and utilising heavy machinery, all of which bring with them a substantial price tag. This disturbed us, because it seems to suggest that land restoration is the domain of those with cash to splash, and that those people or places without the necessary resources may just have to resign themselves to the continued collapse of their landscapes.

Thankfully, we came across the work of the likes of Craig Sponholtz, Brad Lancaster, Bill Zeedyk and Van Clothier, and in Australia, Cam Wilson and Peter Bennett. In their work, these thinkers and practitioners of water management and restoration, offer a radically different approach to watershed restoration. While they don’t flinch from the importance of technical understanding, they cultivate strategies that are based in the thoughful observation of those who are connected to a landscape, that utilise locally available materials, and that draw on community power to create modest interventions that can be tweaked over time. Rather than advising that landowners simply save up and pay an expert, their work seeks to empower communities to manage, monitor and maintain water in their landscapes through accessible, practical and locally-adaptable erosion control and water harvesting responses. In his foreword to Zeedyk and Clothier’s book Let the Water Do the Work, Courtney White articulates the characteristics of this approach: it is evidence-based, its affordability and relative simplicity make it accessible, it is based in ‘soft engineering’, challenging “the dominant paradigms of river and creek restoration”, it requires “humility, attentiveness and patience”, operating at the pace of the ecosystem, and finally, it’s at a human scale, flourishing with the participation of community, that offers “joy in companionship, in learning together, and sharing knowledge.” Continue reading →

A break in the season

The rain gauge almost full!

With the big rains of the last couple of weeks, it feels like we’re approaching an break in the seasons. In most parts of the property, the cracks that open in the clay over summer are softening and closing, and there’s a green fuzz of new growth on the ground (especially in the areas with existing, dry ground cover, we’ve noticed). The sheep march briskly between discoveries of fresh grass and happily fan out over new paddocks.

The magic hour hits the cliffs at Lady Bay.

It’s now officially autumn, and already the air feels a little different. There’s a cool edge to the mornings, and a hint of moisture to the air. The land still feels dry, but we tell ourselves it won’t be long now.

It’s been a dry year on the Fleurieu Peninsula. After the inundation of 2013, 2014’s rainfall came in almost 200mm shy of the year before, and about 100mm short of the average. By February 2015, the dam had receded to a few centimetres of sludge, and the water carter had come to top up the stock water tanks. While there’s no doubt that the Fleurieu Peninsula has had the Mediterranean pattern of dry summers and cool, wet winters for some time, recently I’ve begun to wonder whether this pattern has shifted towards greater aridity as successive land-uses have cleared the landscape.

Curruckalinga, looking over St. Vincent’s Gulf, 1846, George French Angas, depicting a mosaic of woodland and open grassland. From the description: “This view is taken from the rocky hills near Mr Kemmis’s Station, to the northward of Rapid Bay … The undulating appearance of the country here represented, together with the singular manner in which the trees are dotted about in all directions over the landscape … principally ‘casuarinae’ or she-oak, with ‘eucalyptus’.” From the collection of the State Library of South Australia, B15276/33.

At the time of European colonisation, the Fleurieu Peninsula was most likely covered with a mosaic of woodland, forest and grasslands, maintained through Aboriginal burning and land management practices. In his paper on the discovery and settlement of the Fleurieu (1986), Rob Linn draws from the diaries of settlers in his descriptions of the landscape of the South Western Fleurieu. Writing in 1838, William Giles described the landscape around Rapid Bay, as “a most beautiful valley, the soil of great depth covered with most luxuriant herbage … on the sides of these hills we found plenty of keep for sheep, and wherever the grass had been burnt in these places it was looking beautifully verdant … fine land, excellent water, plenty of timber …” This was echoed by John Stephens in 1839, describing the “country from Cape Jervis upwards” as “very picturesque” and “well-timbered” (Linn 1986).

Farm hack: reusing livestock water

When our livestock are moved into the next paddock, or the trough needs a clean, the contents, up to 450 litres of water, are dumped into the pasture. While we’ve tended to hold a ‘survival-of-the-fittest’ mentality for our tree planting, we couldn’t help but feel that this water could be better directed on nearby seedlings. So, a little while ago, we whipped up our first attempt at a stock trough water diverter that would do just this.  Continue reading →

Testing water quality

The DIY water testing kit, including big buckets, little buckets, ice-cube trays, teaspoons, magnifying glass, pH strips, homemade Secchi disk, EC meter, pool net, boots, ID charts and recording sheets. If you have a toddler in attendance, you may consider a change of clothes for yourself and toddler.

Inspired by permaculture’s commitment to observation, over the last couple of years, we’ve become enthusiastic/compulsive gatherers of data about our farm. Everything we can think of to measure, we’ve tried to measure. Now, as we scale up our interventions, we can begin to track our impact and refine our management accordingly. As part of this, we’ve started a seasonal water quality testing program to monitor changes in the quality of our catchment as we revegetate the catchment and manage grazing more intensively.

We’ve assembled our own water testing kit, all stored conveniently in a secondhand mayo bucket from the local chip shop. Using this, there are a few characteristics we’ll test seasonally:

  • salinity and temperature (both tested using an EC (Electrical Conductivity) Meter from your friendly local hydroponics vendor),
  • pH (tested using pool pH strips from the hardware shop),
  • turbidity is a measure of the amount of solids suspended in the water (measured with a DIY Secchi disk or turbidity tube),
  • macroinvertebrate populations, the presence and composition of which is also an indicator of pollution levels (gathered with buckets and nets, and sorted with teaspoons into ice-cube trays).

Fleurieu Foliage: River red gum (Eucalyptus camaldulensis)

After shedding two-thirds of its branches last year, one of our giant red gums is now a forest of new shoots.

As the two remnant trees on our farm, River red gums (Eucalyptus camaldulensis) hold a special place in our hearts. Our red gums are bent and stretch up the hillside away from the prevailing winds. Red gums are not unique to the Fleurieu however, in fact, their high level of adaptability means that they have a distribution across Australia, most commonly occurring on floodplains and waterways as well as throughout higher rainfall regions.

IMG_5466

Not dead yet! After apparently dying in an unusually dry winter and spring, this year-old red gum seedling has re-sprouted from its base after receiving about 10mm of rain over several weeks.

With red gums as a significant species in the past ecosystem of our property, they’ve been a clear choice for revegetation. When planting, we’re constantly inspired by their resilience. I’ve heard it said that red gum roots grow at a centimetre a day, which puts them at over three-and-a-half metres a year. If it’s true, then it’s an indicator of their startling ability to find water and nutrients. We’ve been amazed by some of our red gums that have shot to almost 1.5 metres after a couple of years in the ground, but also by their apparent capacity for dormancy. Some seedlings will sit in dry, cracked clay soil for months on end, leaves green but not growing. Then, with a decent rain, they burst into new growth. Likewise, others appear to have died, leaving nothing but a dry stick until the opening rains of autumn when they reshoot from the ground, sending out a profusion of leaves and spindly branches. We’ve noticed some other plants behave similarly – the occasional melaleuca or acacia for example – but none so consistently and successfully resurrect themselves as the red gum.

The Farm Year in Review: 2014

2014 was a year where the dry season came early and stayed late. It seemed as if the rain barely had a chance to soften the ground and throw up some soursobs before our clay soils began to crack again and the pasture browned off. Despite this, after two years observing the rhythms of this patch of ground, I feel like we’re becoming more resilient and optimistic: where previously we despaired at every lost seedling, now we celebrate every survivor.

Summer: a shingleback lizard soaks up some sunshine.

In the spirit of permaculture, this year also marks a transition from our observational period towards beginning to implement infrastructure for a sustainable farming enterprise. With fencing and water infrastructure for livestock, our appreciation of the need for water only deepens, and despite its challenges, we’ve learnt to stop worrying and love winter.
