A new fence and a kangaroo. Neither are particularly concerned about each other.

A year or so ago, we celebrated the first phase of fencing on the farm: defining our ‘wilderness zones’ by carving out seven-ish hectares of erosion gully, remnant vegetation and waterlogging for regeneration. We commented at the time at how much a few posts and wire redefines a sense of space. Now we’ve almost completed all of the major fencing for the property. What began as essentially one vast, 20-odd hectare paddock, has now been reshaped into 8 smaller paddocks, together with 3 revegetation zones/habitat corridors. Continue reading →

An English oak seedling (Quercus robur) reaches towards the winter sun.

Back in autumn, we gathered freshly fallen acorns from the base of a row of massive old English oaks (Quercus robur). Inspired by the dehesa agroforestry systems of Spain and Portugal, we’ve often pondered how a livestock-grazed oak plantation could work on the property. Acorns for pigs, and perhaps even human consumption, timber for the use of our great-great-grandchildren, and in the meantime, a carpet of fallen leaves offering organic matter for composting and mulch. So, with some bags of acorns and few containers of the topsoil and leaf litter from around the parent oaks, we set to propagating them.

We mixed the leaf litter and gathered topsoil in with our potting medium, hoping to inoculate our own medium with beneficial fungi, and then planted the acorns. We planted some close to the surface, and others about an acorn-width deep. After about eight weeks of being kept damp and left in the late autumn-early winter sun, they began sending their first shoots upwards, red furry things with a cluster of jagged leaves at the top. The depth of the acorn doesn’t seem to have had any bearing on their readiness to propagate. Once they’ve all emerged and are about 8-10 cm tall, we’ll carefully thin them, planting out excess strong specimens to their own pots until we have one decent plant per pot.

Grow little seedling, grow!

The feijoa (Acca sellowiana, aka. Feijoa sellowiana) is one of those underrated suburban fruit trees that is often (perhaps unwittingly) grown around Adelaide backyards and little eaten. The varieties I’ve come across most often have offered grey-green torpedoes with a sharp, pineapple tang and a somewhat gritty texture. In the height of feijoa season, we were given a paper bag full of a variety I’d not encountered before. The skin was thin enough to bite a chunk out of and the flesh silky(ish) and smooth.

In her book Farms with a Future (Chelsea Green, 2012), American small farm consultant, sometime-homesteader and former family rancher Rebecca Thistlethwaite offers a brisk, yet detailed, guide to building and running a sustainable farm business. Writing on a range of essential topics including marketing, land access, finance and business planning, equipment, soil and water management, record-keeping and human resources her writing is concise and targeted, supported by her own experiences together with a selection of excellent case studies describing how the principles outlined are expressed in the real world. Each chapter offers a discussion of key issues and strategies for sustainable farms, a case study and summary of short, sharp “Take Home Messages” drawn from the text. While it is necessarily written for a North American audience, and some US-focussed sections on regulation or financing can be skipped over, there is still much here to inspire Australian readers.

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 →

A One-Page Place Assessment for TBC Farm, Second Valley

Brad Lancaster’s books on Rainwater Harvesting would have to be among the most consistently inspiring books we own. Two volumes into his trilogy on Rainwater Harvesting for Drylands and Beyond, Lancaster combines accumulated community wisdom with permaculture principles to produce lavishly illustrated, practical and highly accessible manuals for managing water in urban and rural environments. Consistent with permaculture thinking, Lancaster urges land managers to spend time observing the season patterns of the landscape to more effectively design for sustainable, integrated water management. One method of doing this is to compile a One Page Place Assessment, drawing together essential climatic and ecological information about your particular location.

Our first year has been one of spreadsheets, mapping out our seasonal observations and activities, and the One Page Place Assessment concept is a elegant way of compiling climatic data from Second Valley and the surrounding area. We’ve finally completed the first version of a place assessment for our property, with much of the data drawn from Bureau of Meteorology stations nearby (Myponga Reservoir being the furthest). While we have tailored information to our particular location, we hope it will be of use to other landowners in the region. We have also referenced information sources so others can draw on the same resources in exploring their own area.

You can download our One Page Place Assessment here. Continue reading →

Book Review: Embracing an arid future in “Growing Food in a Hotter, Drier Land”

Years before there was talk of locavores and 100-mile-diets and omnivore’s dilemmas, I came upon Gary Nabhan’s book Coming Home to Eat, a personal account of his experiences striving to solely eat food produced in his home bioregion of the US-Mexican borderlands in southern Arizona. His observations as renowned desert ecologist and ethno-botanist redefined how I thought about food and sustainability and accompanied me on my own sustainable food explorations for years after.

I get the feeling that his latest book, Growing Food in a Hotter, Drier Land: Lessons from Desert Farmers on Adapting to Climate Uncertainty (Chelsea Green, 2013), may be another companion for us in our adventures on the farm. While Growing Food is as practical as its title suggests, it is permeated by Nabhan’s respect for the insights of cultures deeply connected to the land, and his belief that communities connected to their bioregion are the most resilient in the face of environmental change.

We’ve seeded our last 150 tubes in preparation for planting in a few months time. When the rains come, we’ll have over 1000 plants ready to go. Most are destined for the regeneration areas we’ve fenced around the waterways, but a few others are non-indigenous livestock fodder plants, timber trees and food plants we’ve raised from seed and cuttings to begin developing other zones around the farm.

It’s a Pink Gum Woodland, it just doesn’t know it yet.

Late in 2013, along with a posy of other plant nerds, we attended a workshop with botanist Ann Prescott (author of It’s Blue with Five Petals) to explore ideas behind revegetation for habitat. We walked through remnant woodland in the hills above Yankalilla, and tried to imagine how our farm might have looked 180 years ago. Continue reading →

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.

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 →

A Year on the Block

TBC2013November marks one year since we began our relationship with this patch of soil, grass and rusty car parts. If the permaculture imperative is to obtain a yield, then the yields of this first year have been largely intangible, but no less real. It has been a year of observing and learning about the land, ourselves and what we can do here. I remember emotions I was feeling about this project a year ago, and I think my terror has been mostly balanced by a sense of calm. Where 12 months ago I was overwhelmed by the scale of our ignorance, now, our ignorance is still largely intact, but I’m more confident in our collective abilities as a family, nested within a community, to unravel the challenges we face.
